Definitions
- This invention relates to surgical instruments and procedures for placement of cardiac pacer or defibrillator electrodes, particularly via subxiphoid incision and insertion of an electrode structure in an extrapericardial position with a connected generator disposed in a subcutaneous pocket adjacent the subxiphoid incision.
- Contemporary surgical techniques for installing electrodes on the heart of a patient that is at risk for ventricular fibrillation or bradycardia arrhythmias commonly involves insertion of a wire electrode through the patient's venous system into the heart, and connection of the electrode to an implanted defibrillator or pacemaker. These procedures are commonly performed in a cardiac catheterization lab, under fluoroscopic x-ray guidance. It is desirable to place defibrillator or pacing electrodes in contact with the pericardium of the heart with minimal trauma and simple surgical techniques that can be rapidly implemented, with or without the need for fluoroscopic guidance.
- an electrode structure in accordance with one embodiment of the present invention, includes an inflatable balloon having surface-oriented electrode patches for positioning extrapericardially at a posterior aspect of the sternum.
- the electrode structure is positioned via a subxiphoid incision and entry along a tract of dissected tissue to the posterior aspect of the sternum.
- Orientation of the electrode patches is gauged via radiological or mechanical techniques, and the balloon is inflated to engage the electrode patches on a surface thereof with selected regions of the pericardium.
- Surgical instruments for inserting and placing the electrode structure within the posterior aspect of the sternum are specifically configured to facilitate the placement via the subxiphoid entry.
- Associated electrical conductors are disposed substantially along the dissected tract to an implantable pacer or defibrillator that is inserted into a subcutaneous pocket formed adjacent the subxiphoid entry incision.

- FIGS. 11A and 11B comprise a flow chart illustrating one method embodiment of the present invention.
- a central elongated hollow shaft 9 includes a handle 11 attached to the proximal end of the shaft 9 , and includes a fitting or connector 13 on the distal end of the shaft 9 .
- a mating connector 15 is detachably engaged with the connector 13 , and is attached to the proximal end of a hollow support shaft 19 that includes a tissue-dissecting tapered tip 21 on the distal end.
- An inflatable member 23 preferably inelastic, as later described herein, is also supported on the shaft 19 , and is shown furled or rolled around shaft 19 in an undeployed configuration.
- Electrically conductive patches 25 , 27 include electrical conductors 29 that extend from the member 23 toward the proximal end of the shaft 9 .
- An outer hollow sheath 31 is slidably mounted on the central shaft 9 and extends distally over the mating connectors 13 , 15 , and over the balloon or inflatable member 23 in undeployed configuration substantially to the base of the tapered tip 21 .
- the cable of electrical conductors 29 is also confined within the outer sheath.
- a port 33 communicates with the hollow central shaft 9 for supplying fluid under pressure through the shaft 9 to the inflatable member 23 supported on shaft 19 .
- the instrument illustrated in FIG. 1 is thus configured for insertion into a patient in a manner as later described herein, with the tapered tip 21 aiding advancement of the instrument through a tissue-dissected channel from the subxiphoid incision toward the anterior pericardium.
- the proximal end of the support tube 19 may be internally threaded, and mating threads on the distal end of the central shaft 9 screw into the support tube to fix the balloon 23 onto the central shaft.
- the hub 15 attached to the proximal end of the support tube 19 includes a non-round cavity that mates with the corresponding connector 13 on the distal end of the central shaft.
- the balloon 23 deflates upon detachment of the central shaft 9 from the support shaft 19 .
- the balloon 23 stays in position on the anterior pericardium due to the conformance of the balloon 23 to the extra-pericardial cavity formed during balloon inflation.
- frictional members or small protrusions can be disposed on the balloon 23 to maintain the position of the electrodes.
- a sealing valve may be added to the connector 15 , such as a check-ball valve 35 , to ensure that the balloon does not deflate upon detachment of the central shaft 9 .
- the balloon retained in inflated configuration is less likely to migrate out of position after insertion.
- the balloon may be deflated via percutaneous needle puncture in the intercostal space.
- the balloon surface may be coated or covered with fabric or coarse-mesh material or other suitable material 50 that promotes fibrous adhesions to hold the balloon in place. Such coating or covering may be applied to the side opposite the patch electrodes 25 , 27 , or may be on both sides of the balloon except at the locations of the electrodes.
- FIG. 2 there is shown a pictorial sectional diagram of the instrument in FIG. 1 re-configured with the outer sheath 31 drawn back proximally to the handle 11 to expose the inflatable member 23 and the mating connectors 13 , 15 between central shaft 9 and support shaft 19 .
- the inflatable member 23 can be inflated with fluid (e.g., air or saline solution) under pressure to deploy the inflatable member 23 , as illustrated in FIG. 3 .
- fluid e.g., air or saline solution
- the inflatable member 23 includes two substantially circular membranes of flexible but substantially inelastic material such as mylar or polyurethane that are bonded together substantially only around the periphery thereof (and to the support shaft 19 ) to form a disk-like balloon having an interior between the membranes that is disposed in fluid communication with the hollow support shaft 19 .
- One disk-like surface of the member 23 supports one or more electrode patches 25 , 27 that are spaced apart to form pericardium-engaging contact electrodes.
- the patch electrodes 25 , 27 may include surface pads of sputtered metal or organic conductive compounds or mesh or spiral grids that are affixed to the outer surface of the posterior membrane, as shown in the bottom view of FIGS. 3 and 4 .
- the space between the membranes may thus be pressurized to expand the thickness of the member 23 .
- the mating connectors 13 , 15 may include a check valve such as a spring-biased ball 35 against a valve seat in connector 15 for retaining fluid pressure within the member 23 once pressurized through the central shaft 9 and support shaft 19 . Thereafter, the mating connectors 13 , 15 are detached or disconnected, leaving in place the inflated member 23 with attached shaft 19 , connector 15 and tip 21 , as shown in FIG. 4 .
- the cable 29 of electrical conductors connected to the electrode patches 25 , 27 may be suitably routed, as discussed later herein, for connection via connector 37 to an implantable defibrillator or pacer unit 53 .
- FIG. 5 there is shown a pictorial side view of the instrument of FIG. 1 being positioned within a patient.
- an incision of about 2 cm length is formed in the subxiphoid region, and blunt dissection is conducted to expose the linea alba, which is also incised a length of about 2 cm.
- a surgeon's gloved index finger is inserted in the incision in a superior direction, and a tract is bluntly dissected to the posterior aspect of the sternum.
- the finger is withdrawn, and the instrument in the configuration of FIG. 1 is inserted through the incision and advanced to dissect tissue along a path toward the posterior aspect of the sternum.
- the distal balloon 23 is constrained within the outer sheath 31 as the tapered tip 21 dissects tissue along the path.
- the maximal diameter of the portion of the instrument that is inserted into the body is approximately 10-12 mm, in the area of the sheathed balloon 23 .
- the instrument is inserted without a sweeping motion, keeping the dissected tissue tract limited to about the 12 mm diameter of the instrument. Torsion about the long axis of the instrument may be employed to advance the instrument through tissue substantially in contact with the posterior aspect of the sternum. This allows the instrument to form a tract anterior to the anterior surface of the pericardium without poking the heart.
- the instrument is advanced until the balloon member 23 is centered on the anterior surface of the heart 100 .
- Advancement of the instrument may be performed under fluoroscopic visualization oriented in a lateral direction to visualize the tip 21 in contact with the posterior aspect of the sternum and directed away from the heart 100 .
- the instrument may be straight and rigid, as shown in FIG. 1 .
- the outer sheath 31 of the instrument may be slid back along the central shaft proximally toward the handle 11 to expose the balloon member 23 , as shown.
- the balloon member 23 is inflated to occupy the region between the posterior aspect of the sternum and the anterior pericardium, with the patch electrodes 25 , 27 held resiliently in contact with the pericardium at selected locations, for example, adjacent the right atrium and the left ventricle.
- the central shaft 9 may then be detached from the support shaft 19 at the connectors 13 , 15 , leaving the member 23 pressurized in place (if connector 15 includes a check valve, as previously described), as illustrated in FIG. 6 , or depressurized in place (if connector 15 does not include a check valve).
- FIG. 7 Another embodiment of the present invention, as illustrated in FIG. 7 , facilitates placement of the inflatable member 23 without fluoroscopic guidance.
- this configuration of the instrument includes a curved central shaft 39 and an outer sheath 41 of mating curve slidably mounted on the shaft 39 that is formed in a generally U-shape with the handle 42 extending up and forward ending generally parallel to the long axis of the shaft 39 .
- An indicator 43 may extend from the handle (or the shaft 39 and handle 42 may extend) to position the tip 45 of the indicator, when in use, outside the body corresponding to the position of the tip 47 inside the body.
- the portion of the instrument for positioning inside the body is curved concave upwardly so that, as the instrument is advanced, the tip 47 is directed into contact with the posterior sternal surface, as shown in FIG. 8 .
- a standard chest X-ray of the patient in an AP (anterior-posterior) orientation may be used initially to determine a desired position of the tip 47 of the instrument.
- the heart shadow in an AP chest X-ray and its position with respect to the rib cage and sternum can be noted with reference to a correct placement of the tip 47 of the instrument in order to position the balloon 23 and electrode pads 25 , 27 on the heart.
- the patient's chest is palpated to count the ribs and delineate the sternal edge, and the desired spot for location of the tip 47 may be marked on the patient's skin.
- the external indicator 43 , 45 aligns with the patient's skin marking, and the internal portion of the instrument including the balloon 23 is correctly placed.
- the sheath 41 is retracted to expose the balloon 23 .
- the balloon is inflated to create a cavity anterior to the anterior portion of the pericardium.
- the balloon 23 contains two or more patch electrodes 25 , 27 , as previously described herein, that are oriented on the inferior side of the balloon.
- the balloon is substantially flat with an outer diameter of approximately 7-8 cm. Balloon inflation creates a cavity in adjacent tissue that conforms to the dimensions of the balloon 23 to hold the balloon 23 in the correct position against the heart 100 , as shown in FIG. 9 .
- the shaft 39 and handle 42 are detached from the balloon 23 by unscrewing the flexible mounting shaft 40 from the mating threaded connector 44 on the electrode structure to remove the central shaft 39 and sheath 41 and handle assembly 40 , 42 , 43 from the patient, leaving the balloon-oriented electrode structure 23 in place. Detachment of the mounting shaft 40 may facilitate deflation of the balloon 23 (in the absence of a check valve, as previously described herein), or may leave the balloon 23 inflated (with a check valve installed).
- the cable 29 of insulated conductive leads connected to the patch electrodes 25 , 27 is routed through the tract of dissected tissue back to the subxiphoid incision 51 , and is connected to the implantable generator 53 (pacer or defibrillator). The generator 53 is inserted into a subcutaneous pocket formed adjacent the subxiphoid incision 51 .
- FIG. 10 there is shown a partially cutaway pictorial view of another embodiment of the present invention in which a linear defibrillation or pacing cannula 46 of suitable flexibility may be advanced from a subxiphoid incision into position on the anterior pericardium.
- the cannula 46 may have two or more ring electrodes 48 , 52 near its distal end, allowing conduction through the pericardium to the heart when the cannula 46 is positioned and the conductive leads 54 , 55 from the ring electrodes 48 , 52 are connected to the implantable generator 53 .
- the circumferential ring electrodes 48 , 52 ensure that electrical contact occurs with the anterior pericardium regardless of the angular orientation of the cannula 46 about its axis of elongation.
- the cannula 46 includes a central lumen 56 to accommodate a rigid obturator 58 that increases the stiffness of the cannula 46 and facilitates its advancement through tissue.
- the obturator may be disposed about the cannula as an outer sheath or tube.
- Conductive wires 54 , 55 from the electrodes 48 , 52 to the proximal end of the cannula 46 and connectors 57 , 59 on the proximal end of the conductive wires 54 , 55 interface with the generator unit 53 that is implanted near the subxiphoid incision, as previously described herein.
- Cannula insertion is performed by advancement in a straight line from the subxiphoid incision, without sweeping the cannula 46 back and forth. Torsion or twisting of the cannula 46 may be performed during insertion to facilitate advancement through tissue.
- the obturator 58 may be withdrawn from within the central lumen 56 . Placement of the linear cannula 46 is simpler, as it does not require retraction of an overlying sheath or balloon inflation, and straight line insertion of the cannula 46 through tissue may adequately anchor the ring electrodes 48 , 52 in contact with the anterior pericardium.
- the procedure for placing an electrode structure in contact with the heart of a patient proceeds from initial formation of a subxiphoid entry incision 61 .
- Blunt tissue dissection is performed to expose the linea alba 62 which is incised 63 .
- the surgeon uses a gloved finger to dissect an initial tract 64 from the subxiphoid incision to the posterior aspect of the sternum.
- the instrument supporting the electrode structure in a configuration as illustrated in FIG. 1 or 7 or 10 , is inserted 65 into the initial tract and is advanced through tissue to a position posterior the sternum and anterior the anterior pericardium. The proper positioning of the instrument in an embodiment as illustrated in FIG. 1 or FIG.
- FIG. 7A A standard chest x-ray of a patient in an AP orientation may be used initially to determine a desired position of the distal tip of the instrument.
- the heart shadow in such an x-ray image and its position relative to the rib cage and sternum can be designated for correct positioning of the distal tip and the associated electrodes for proper contact with the pericardium.
- the patient's skin may be marked to designate the correct positioning of the alignment tip 45 of the instrument in the configuration illustrated in FIG. 7A .
- the instrument in this configuration is inserted through the subxiphoid entry incision, and is advanced superiorly until the external indicator 45 aligns with markings on the patient's skin to designate proper positioning of the electrode structure relative to the heart.
- the overlying sheath is slid back along the central shaft to expose 69 the electrode structure including the balloon 23 that supports the electrode pads 25 , 27 .
- the balloon is then inflated through the gas port 33 to expand the thickness of the electrode structure sufficiently to contact 69 the electrode pads 25 , 27 with the anterior pericardium.
- the instrument in an embodiment of FIG. 7A is positioned 68 with the electrodes in contact with the pericardium. The proper position of the instrument can be verified, as previously described herein.
- the central shaft may be detached 71 from the electrode structure, leaving the balloon 23 and electrode pads 25 , 27 in position, for removal of the central shaft and the overlying sheath from within the tract of dissected tissue.
- the removal of the sheath and central shaft of the positioning instrument also releases and positions 73 the cable of electrical conductors that are attached to the electrode pads within the tract of dissected tissue to extend toward the subxiphoid entry incision.
- These conductors are then attached to a generator 75 .
- a subcutaneous pocket is formed 77 near the subxiphoid entry incision and the generator is implanted 79 in the subcutaneous pocket. The subxiphoid entry incision is then closed.
- the obturator 58 is withdrawn 71 from within the central lumen 56 , leaving the ring electrode 48 , 52 of the insertion cannula 46 in contact with the anterior pericardium.
- the conductive leads 54 , 55 extend from the proximal end of the insertion cannula 46 . These leads are positioned within the tract of dissected tissue 73 for attachment 75 to a generator, as previously described herein.
- a subcutaneous pocket is formed 77 adjacent the subxiphoid incision, and the generator with attached leads is placed within the pocket 79 , and the subxiphoid incision is closed 81 .
- the surgical instruments and surgical procedures for placing an electrode structure in contact with the heart advances an electrode structure through a subxiphoid access tract to a posterior aspect of the sternum and the anterior pericardium.
- the simplified surgical procedure using an embodiment of the present invention facilitates proper placement of the electrode structure with fluoroscopic visualization or x-ray positioning for minimal trauma to the patient.
- Conductive leads from contact electrodes of the electrode structure are routed along the access tract to the subxiphoid incision for connection to a pulse generator or defibrillator that is implanted within a subcutaneous pocket near the subxiphoid incision.

Electricallyconductive patches FIGS. 3 and 4 , includeelectrical conductors 29 that extend from themember 23 toward the proximal end of theshaft 9. An outerhollow sheath 31 is slidably mounted on thecentral shaft 9 and extends distally over themating connectors inflatable member 23 in undeployed configuration substantially to the base of thetapered tip 21. The cable ofelectrical conductors 29 is also confined within the outer sheath. Aport 33 communicates with the hollowcentral shaft 9 for supplying fluid under pressure through theshaft 9 to theinflatable member 23 supported onshaft 19. The instrument illustrated inFIG. 1 is thus configured for insertion into a patient in a manner as later described herein, with thetapered tip 21 aiding advancement of the instrument through a tissue-dissected channel from the subxiphoid incision toward the anterior pericardium. - The proximal end of the
support tube 19 may be internally threaded, and mating threads on the distal end of thecentral shaft 9 screw into the support tube to fix theballoon 23 onto the central shaft. Thehub 15 attached to the proximal end of thesupport tube 19 includes a non-round cavity that mates with thecorresponding connector 13 on the distal end of the central shaft. Thus, when thesupport shaft 19 and thecentral shaft 9 are screwed together, or are otherwise detachably connected, the assembly may be rotated, and torque may be transmitted to thetip 21 of the instrument for bluntly dissecting tissue. Keying of theconnectors balloon 23 so that thepatch electrodes balloon 23 deflates upon detachment of thecentral shaft 9 from thesupport shaft 19. However, theballoon 23 stays in position on the anterior pericardium due to the conformance of theballoon 23 to the extra-pericardial cavity formed during balloon inflation. Similarly, frictional members or small protrusions can be disposed on theballoon 23 to maintain the position of the electrodes. - In another embodiment of the invention, a sealing valve may be added to the
connector 15, such as a check-ball valve 35, to ensure that the balloon does not deflate upon detachment of thecentral shaft 9. The balloon retained in inflated configuration is less likely to migrate out of position after insertion. After several days to several weeks, the balloon may be deflated via percutaneous needle puncture in the intercostal space. Additionally, the balloon surface may be coated or covered with fabric or coarse-mesh material or othersuitable material 50 that promotes fibrous adhesions to hold the balloon in place. Such coating or covering may be applied to the side opposite thepatch electrodes - Referring now to
FIG. 2 , there is shown a pictorial sectional diagram of the instrument inFIG. 1 re-configured with theouter sheath 31 drawn back proximally to thehandle 11 to expose theinflatable member 23 and themating connectors central shaft 9 andsupport shaft 19. In this configuration, theinflatable member 23 can be inflated with fluid (e.g., air or saline solution) under pressure to deploy theinflatable member 23, as illustrated inFIG. 3 . - The
inflatable member 23 includes two substantially circular membranes of flexible but substantially inelastic material such as mylar or polyurethane that are bonded together substantially only around the periphery thereof (and to the support shaft 19) to form a disk-like balloon having an interior between the membranes that is disposed in fluid communication with thehollow support shaft 19. One disk-like surface of themember 23 supports one ormore electrode patches patch electrodes FIGS. 3 and 4 . The space between the membranes may thus be pressurized to expand the thickness of themember 23. Themating connectors biased ball 35 against a valve seat inconnector 15 for retaining fluid pressure within themember 23 once pressurized through thecentral shaft 9 and supportshaft 19. Thereafter, themating connectors member 23 with attachedshaft 19,connector 15 andtip 21, as shown inFIG. 4 . Thecable 29 of electrical conductors connected to theelectrode patches connector 37 to an implantable defibrillator orpacer unit 53. - Referring now to
FIG. 5 there is shown a pictorial side view of the instrument ofFIG. 1 being positioned within a patient. To place the instrument as shown, an incision of about 2 cm length is formed in the subxiphoid region, and blunt dissection is conducted to expose the linea alba, which is also incised a length of about 2 cm. A surgeon's gloved index finger is inserted in the incision in a superior direction, and a tract is bluntly dissected to the posterior aspect of the sternum. The finger is withdrawn, and the instrument in the configuration ofFIG. 1 is inserted through the incision and advanced to dissect tissue along a path toward the posterior aspect of the sternum. Thedistal balloon 23 is constrained within theouter sheath 31 as the taperedtip 21 dissects tissue along the path. The maximal diameter of the portion of the instrument that is inserted into the body is approximately 10-12 mm, in the area of the sheathedballoon 23. The instrument is inserted without a sweeping motion, keeping the dissected tissue tract limited to about the 12 mm diameter of the instrument. Torsion about the long axis of the instrument may be employed to advance the instrument through tissue substantially in contact with the posterior aspect of the sternum. This allows the instrument to form a tract anterior to the anterior surface of the pericardium without poking the heart. The instrument is advanced until theballoon member 23 is centered on the anterior surface of theheart 100. Advancement of the instrument may be performed under fluoroscopic visualization oriented in a lateral direction to visualize thetip 21 in contact with the posterior aspect of the sternum and directed away from theheart 100. The instrument may be straight and rigid, as shown inFIG. 1 . Once properly positioned, theouter sheath 31 of the instrument may be slid back along the central shaft proximally toward thehandle 11 to expose theballoon member 23, as shown. Theballoon member 23 is inflated to occupy the region between the posterior aspect of the sternum and the anterior pericardium, with thepatch electrodes central shaft 9 may then be detached from thesupport shaft 19 at theconnectors member 23 pressurized in place (ifconnector 15 includes a check valve, as previously described), as illustrated inFIG. 6 , or depressurized in place (ifconnector 15 does not include a check valve). - Another embodiment of the present invention, as illustrated in
FIG. 7 , facilitates placement of theinflatable member 23 without fluoroscopic guidance. Specifically, this configuration of the instrument includes a curvedcentral shaft 39 and anouter sheath 41 of mating curve slidably mounted on theshaft 39 that is formed in a generally U-shape with thehandle 42 extending up and forward ending generally parallel to the long axis of theshaft 39. Anindicator 43 may extend from the handle (or theshaft 39 and handle 42 may extend) to position thetip 45 of the indicator, when in use, outside the body corresponding to the position of thetip 47 inside the body. The portion of the instrument for positioning inside the body is curved concave upwardly so that, as the instrument is advanced, thetip 47 is directed into contact with the posterior sternal surface, as shown inFIG. 8 . A standard chest X-ray of the patient in an AP (anterior-posterior) orientation may be used initially to determine a desired position of thetip 47 of the instrument. The heart shadow in an AP chest X-ray and its position with respect to the rib cage and sternum can be noted with reference to a correct placement of thetip 47 of the instrument in order to position theballoon 23 andelectrode pads tip 47 may be marked on the patient's skin. When the instrument is inserted through the subxiphoid incision and advanced superiorly, theexternal indicator balloon 23 is correctly placed. - Once the instrument is advanced to the desired position, the
sheath 41 is retracted to expose theballoon 23. The balloon is inflated to create a cavity anterior to the anterior portion of the pericardium. Theballoon 23 contains two ormore patch electrodes balloon 23 to hold theballoon 23 in the correct position against theheart 100, as shown inFIG. 9 . Following balloon placement, theshaft 39 and handle 42 are detached from theballoon 23 by unscrewing the flexible mountingshaft 40 from the mating threadedconnector 44 on the electrode structure to remove thecentral shaft 39 andsheath 41 and handleassembly electrode structure 23 in place. Detachment of the mountingshaft 40 may facilitate deflation of the balloon 23 (in the absence of a check valve, as previously described herein), or may leave theballoon 23 inflated (with a check valve installed). Thecable 29 of insulated conductive leads connected to thepatch electrodes subxiphoid incision 51, and is connected to the implantable generator 53 (pacer or defibrillator). Thegenerator 53 is inserted into a subcutaneous pocket formed adjacent thesubxiphoid incision 51. - Referring now to
FIG. 10 , there is shown a partially cutaway pictorial view of another embodiment of the present invention in which a linear defibrillation or pacingcannula 46 of suitable flexibility may be advanced from a subxiphoid incision into position on the anterior pericardium. Thecannula 46 may have two ormore ring electrodes cannula 46 is positioned and the conductive leads 54, 55 from thering electrodes implantable generator 53. Thecircumferential ring electrodes cannula 46 about its axis of elongation. Thecannula 46 includes acentral lumen 56 to accommodate arigid obturator 58 that increases the stiffness of thecannula 46 and facilitates its advancement through tissue. Alternatively, the obturator may be disposed about the cannula as an outer sheath or tube.Conductive wires electrodes cannula 46 andconnectors conductive wires generator unit 53 that is implanted near the subxiphoid incision, as previously described herein. Cannula insertion is performed by advancement in a straight line from the subxiphoid incision, without sweeping thecannula 46 back and forth. Torsion or twisting of thecannula 46 may be performed during insertion to facilitate advancement through tissue. Following insertion of thecannula 46 into position of thering electrodes obturator 58 may be withdrawn from within thecentral lumen 56. Placement of thelinear cannula 46 is simpler, as it does not require retraction of an overlying sheath or balloon inflation, and straight line insertion of thecannula 46 through tissue may adequately anchor thering electrodes - Referring now to the flow chart of
FIGS. 11A and 11B , the procedure for placing an electrode structure in contact with the heart of a patient proceeds from initial formation of asubxiphoid entry incision 61. Blunt tissue dissection is performed to expose thelinea alba 62 which is incised 63. The surgeon uses a gloved finger to dissect aninitial tract 64 from the subxiphoid incision to the posterior aspect of the sternum. The instrument supporting the electrode structure, in a configuration as illustrated inFIG. 1 or 7 or 10, is inserted 65 into the initial tract and is advanced through tissue to a position posterior the sternum and anterior the anterior pericardium. The proper positioning of the instrument in an embodiment as illustrated inFIG. 1 orFIG. 10 can be verified 67 using such radiological visualization as fluoroscopy or x-ray imaging. Alternatively, proper positioning of the electrode structure may be accomplished without requiring radiological visualization and guidance of the instrument using the embodiment of the present invention in a configuration as illustrated inFIG. 7A . A standard chest x-ray of a patient in an AP orientation may be used initially to determine a desired position of the distal tip of the instrument. The heart shadow in such an x-ray image and its position relative to the rib cage and sternum can be designated for correct positioning of the distal tip and the associated electrodes for proper contact with the pericardium. The patient's skin may be marked to designate the correct positioning of thealignment tip 45 of the instrument in the configuration illustrated inFIG. 7A . Then, the instrument in this configuration is inserted through the subxiphoid entry incision, and is advanced superiorly until theexternal indicator 45 aligns with markings on the patient's skin to designate proper positioning of the electrode structure relative to the heart. - After the instrument in an embodiment of
FIG. 1 or 7 is properly positioned posterior of the sternum and anterior of theanterior pericardium 66, the overlying sheath is slid back along the central shaft to expose 69 the electrode structure including theballoon 23 that supports theelectrode pads gas port 33 to expand the thickness of the electrode structure sufficiently to contact 69 theelectrode pads FIG. 7A is positioned 68 with the electrodes in contact with the pericardium. The proper position of the instrument can be verified, as previously described herein. Thereafter, the central shaft may be detached 71 from the electrode structure, leaving theballoon 23 andelectrode pads generator 75. A subcutaneous pocket is formed 77 near the subxiphoid entry incision and the generator is implanted 79 in the subcutaneous pocket. The subxiphoid entry incision is then closed. - After the instrument in an embodiment of
FIG. 10 is properly positioned posterior of the sternum and anterior of theanterior pericardium 68, theobturator 58 is withdrawn 71 from within thecentral lumen 56, leaving thering electrode insertion cannula 46 in contact with the anterior pericardium. The conductive leads 54, 55 extend from the proximal end of theinsertion cannula 46. These leads are positioned within the tract of dissectedtissue 73 forattachment 75 to a generator, as previously described herein. A subcutaneous pocket is formed 77 adjacent the subxiphoid incision, and the generator with attached leads is placed within thepocket 79, and the subxiphoid incision is closed 81. - Therefore, the surgical instruments and surgical procedures for placing an electrode structure in contact with the heart advances an electrode structure through a subxiphoid access tract to a posterior aspect of the sternum and the anterior pericardium. The simplified surgical procedure using an embodiment of the present invention facilitates proper placement of the electrode structure with fluoroscopic visualization or x-ray positioning for minimal trauma to the patient. Conductive leads from contact electrodes of the electrode structure are routed along the access tract to the subxiphoid incision for connection to a pulse generator or defibrillator that is implanted within a subcutaneous pocket near the subxiphoid incision.
