Definitions
- the present invention relates to a medical catheter and more particularly to a catheter for the transvascular deployment of expandable medical devices, such as an intravascular embolic filter device, in a collapsed condition.
- the device as described herein relates to a carotid angioplasty procedure with an, intravascular filter being placed distally to capture procedural emboli being released.
- Other medical procedures warrant the use of distal protection systems.
- Angioplasty and stenting of surgically implanted Saphenous Vein grafts that have stenosed and primary treatment of Renal artery stenoses are applicable also. Indeed, the insertion of embolic protection devices to protect patients during any vascular surgery is envisioned as being applicable to this invention.
- embolic protection device in the form of a filter element for placing in a desired position has been described in our co-pending Patent Application No. PCT ⁇ IE98 ⁇ 00093 the contents of which are incorporated herein by reference.
- this filter element is compressed into a housing or pod to advance it to the required location in a vessel. Once in situ the housing is withdrawn or the filter element is advanced. This allows the compressed filter element to expand to the required size and occlude the vessel except for the path or paths provided through the filter which thus provides a pathway for blood and has means for capturing and retaining undesired embolic material released during the surgical operation or percutaneous interventional procedure.
- Difficulties may arise if, for example, the catheter tube, or more particularly the pod as the pod effectively leads in the insertion, were to damage the artery sidewall and thus cause for example a break-away of atherosclerotic plaque from the carotid arteries.
- the device needs to be efficiently compressed.
- the resulting compressed device needs to be manipulated in its pod as efficiently as possible. Further, there is a need for loading such catheters in a way that will facilitate their use on unloading.
- stent delivery systems essentially comprising a catheter with a stent mounted in a collapsed state at a distal end of the catheter under a retractable outer sheath. An abutment within the bore of the catheter spaced proximally from the distal end of the catheter prevents retraction of the stent as the outer sheath is withdrawn over the stent.
- Each of these devices has at least two main components, namely an inner catheter and an outer sheath which is slidably retractable on the catheter to expose the stent for deployment.
- Catheters of this type tend to be relatively long and the loading of a medical device within the distal end of the catheter prior to use can be a somewhat cumbersome operation for the surgeon.
- the length of the catheters makes them unwieldy and difficult to keep sterile.
- the present invention is directed towards overcoming these problems.

- the catheter body has an inner tubular core encased within a concentric thin-walled tubular outer sheath which is fixed to the core, the sheath being extended outwardly of a distal end of the core to form the pod.
- the advantage of using the thin-walled tube is that the maximum volume to retain the medical device for deployment is achieved. Further the pod is relatively flexible on the catheter further facilitating its manipulation and passage through vasculature to the desired site of use.
- the inner tubular core is formed from a steel spring, but may alternatively be formed from polymeric material. Any suitable material may be used as the core is now covered by the thin-walled tubular outer sheath which is effectively the important tube, being the vessel contact surface. Alternatively, a thin walled pod may be achieved by locally thinning a polymeric tube at the distal end of the tube.
- the thin-walled tube is manufactured from a low friction material and ideally is manufactured from polytetrafluoroethylene (PTFE) often sold under the Registered Trade Mark TEFLON.
- the thin walled tube may alternatively be manufactured from any other suitable thin walled material of low friction coefficient or employing a friction reducing agent or component to minimise the friction coefficient.
- PTFE polytetrafluoroethylene
- the advantage of this is that firstly the catheter will not damage arteries, for example the carotid, knocking off atherosclerotic plaque. Further this will allow the easy removal of the implant from th catheter.
- outer thin walled tube is formed of PTFE, it would typically have a thickness of less than 0.004 inches.
- the thickness of thin walled tubes of other materials may vary somewhat depending on the characteristics of the material being used.

- the loading device comprises means for radially compressing the medical device.
- the loading device comprises a funnel having an enlarged inlet end and a narrowed outlet end, the outlet end being engageable within the pod.
- the loading device comprises a main support having a funnel-shaped bore formed from a frusto-conical filter device receiving portion terminating in a cylindrical portion formed by a thin-walled loading tube projecting from the main support.
- This funnel-like arrangement is a very suitable arrangement of loading a pod on the catheter with a compressible filter device.
- the cone angle is between 15° and 65° and preferably may be between 35° and 45°. This allows a sufficiently gentle compression of a filter device, particularly one of a polymeric material.
- the main support is formed from perspex and the thin-walled loading tube is formed from PTFE material.
- the perspex gives a smooth surface.
- the loading tube is mounted on the main support on a metal spigot at an outlet end of the funnel.

Abstract
A medical catheter for the transvascular deployment of a collapsible medical device such as a filter has a tubular body formed by an inner tubular core surrounded by an outer thin-walled tube which is fixed to the core. The outer thin-walled tube extends outwardly beyond a distal end of the core to form a fixed thin-walled medical device embracing pod. The filter is carried on a guidewire which is slidably engagable within a central lumen of the core and the filter can be collapsed against the guidewire for loading within the pod. With the filter thus loaded within the pod the distal end of the catheter can be manoeuvred through a patient's vascular system to a desired deployment site where the filter is discharged from the pod allowing the filter to expand within the blood vessel for use filtering blood flowing through the blood vessel.
Description
- The present invention relates to a medical catheter and more particularly to a catheter for the transvascular deployment of expandable medical devices, such as an intravascular embolic filter device, in a collapsed condition.
- The device as described herein relates to a carotid angioplasty procedure with an, intravascular filter being placed distally to capture procedural emboli being released. Other medical procedures warrant the use of distal protection systems. Angioplasty and stenting of surgically implanted Saphenous Vein grafts that have stenosed and primary treatment of Renal artery stenoses are applicable also. Indeed, the insertion of embolic protection devices to protect patients during any vascular surgery is envisioned as being applicable to this invention.
- A particularly useful form of embolic protection device in the form of a filter element for placing in a desired position has been described in our co-pending Patent Application No. PCT\IE98\00093 the contents of which are incorporated herein by reference. For example, this filter element is compressed into a housing or pod to advance it to the required location in a vessel. Once in situ the housing is withdrawn or the filter element is advanced. This allows the compressed filter element to expand to the required size and occlude the vessel except for the path or paths provided through the filter which thus provides a pathway for blood and has means for capturing and retaining undesired embolic material released during the surgical operation or percutaneous interventional procedure.
- There are difficulties with such expandable devices, whether they be filters or other devices in that firstly they have to be correctly and efficiently compressed and retained within the pod so that when released from the pod, they will expand to assume the correct shape and will not have been distorted by the compression within the pod. The problems of distortion or incorrect expansion tend to be exacerbated if the medical device is stored for long periods within the pod prior to use. Secondly, it is important that the pod and the catheter tube itself be manipulated to the site of use without causing damage to, for example, the arteries through which it is being manipulated. Difficulties may arise if, for example, the catheter tube, or more particularly the pod as the pod effectively leads in the insertion, were to damage the artery sidewall and thus cause for example a break-away of atherosclerotic plaque from the carotid arteries.
- Essentially this leads to certain requirements. The device needs to be efficiently compressed. The resulting compressed device needs to be manipulated in its pod as efficiently as possible. Further, there is a need for loading such catheters in a way that will facilitate their use on unloading.
- It is known to mount implantable medical devices at a distal end of a delivery catheter for transvascular deployment. Upon reaching a desired location within a patients vasculature the catheter is withdrawn relative to the medical device thus allowing the medical device to expand or be expanded within the blood vessel. In the prior art WO98/07387 and U.S. Pat. No. 5,064,435 show stent delivery systems essentially comprising a catheter with a stent mounted in a collapsed state at a distal end of the catheter under a retractable outer sheath. An abutment within the bore of the catheter spaced proximally from the distal end of the catheter prevents retraction of the stent as the outer sheath is withdrawn over the stent. Each of these devices has at least two main components, namely an inner catheter and an outer sheath which is slidably retractable on the catheter to expose the stent for deployment.
- These deployment catheters need to have lateral flexibility in order to manoeuvre through the vascalature but at the same time be sufficiently pushable so that they can be steered and manipulated through the vascalature. The mounting of a medical device within the distal end of the catheter either greatly limits the size of the medical device that can be accommodated or necessitates enlargement of the catheter which restricts access of the catheter within the vascalature of a patient.
- Catheters of this type tend to be relatively long and the loading of a medical device within the distal end of the catheter prior to use can be a somewhat cumbersome operation for the surgeon. The length of the catheters makes them unwieldy and difficult to keep sterile. There is also a difficulty in ensuring air is excluded from the medical device and catheter during loading.
- The present invention is directed towards overcoming these problems.
- According to the invention there is provided a catheter for the transvascular deployment of a medical device, the catheter comprising an elongate tubular body having a proximal end and a distal end, a tubular housing being formed at the distal end of the body for reception of the medical device, a deployment means for engagement with the medical device, being movable through the housing to move the medical device between a stored position within the housing and an in-use position externally of the housing, characterised in that the housing comprises a tubular thin-walled medical device embracing pod fixed at the distal end of the body, the pod extending outwardly from the distal end of the body and forming an extension thereof. Conveniently, the pod and the catheter body form a single integral unit for deployment of the medical device.
- Preferably the catheter body has an inner tubular core encased within a concentric thin-walled tubular outer sheath which is fixed to the core, the sheath being extended outwardly of a distal end of the core to form the pod.
- The advantage of using the thin-walled tube is that the maximum volume to retain the medical device for deployment is achieved. Further the pod is relatively flexible on the catheter further facilitating its manipulation and passage through vasculature to the desired site of use.
- Preferably the inner tubular core is formed from a steel spring, but may alternatively be formed from polymeric material. Any suitable material may be used as the core is now covered by the thin-walled tubular outer sheath which is effectively the important tube, being the vessel contact surface. Alternatively, a thin walled pod may be achieved by locally thinning a polymeric tube at the distal end of the tube.
- Preferably the thin-walled tube is manufactured from a low friction material and ideally is manufactured from polytetrafluoroethylene (PTFE) often sold under the Registered Trade Mark TEFLON. The thin walled tube may alternatively be manufactured from any other suitable thin walled material of low friction coefficient or employing a friction reducing agent or component to minimise the friction coefficient. The advantage of this is that firstly the catheter will not damage arteries, for example the carotid, knocking off atherosclerotic plaque. Further this will allow the easy removal of the implant from th catheter.
- Where the outer thin walled tube is formed of PTFE, it would typically have a thickness of less than 0.004 inches. The thickness of thin walled tubes of other materials may vary somewhat depending on the characteristics of the material being used.
- In another aspect the invention provides a method of loading such a catheter comprising:
- inserting a loading tube into the pod at a free end of the outer thin-walled tube; and
- compressing the medical device and delivering the compressed medical device through the loading tube into the pod.
- The problem is that if one did not insert the loading tube into the pod the thin-walled tube would collapse in compression when trying to insert the medical device. The use of the loading tube prevents such collapse.
- Preferably the loading tube is a further thin-walled tube which is inserted into the pod for smooth delivery of the medical device into the pod.
- Ideally the medical device is compressed by delivering the filter device through a funnel and into the loading tube which is mounted at an outlet of the funnel.
- In another aspect the invention provides a delivery system for transvascular deployment of a medical device, the system comprising a catheter in combination with an associated separate loading device which is operable to collapse the medical device from an expanded in-use position to a collapsed position for reception within the pod.
- Preferably the loading device comprises means for radially compressing the medical device.
- In a particularly preferred embodiment the loading device comprises a funnel having an enlarged inlet end and a narrowed outlet end, the outlet end being engageable within the pod.
- In another embodiment, the loading device comprises a main support having a funnel-shaped bore formed from a frusto-conical filter device receiving portion terminating in a cylindrical portion formed by a thin-walled loading tube projecting from the main support. This funnel-like arrangement is a very suitable arrangement of loading a pod on the catheter with a compressible filter device.
- Ideally the cone angle is between 15° and 65° and preferably may be between 35° and 45°. This allows a sufficiently gentle compression of a filter device, particularly one of a polymeric material.
- In one particularly preferred embodiment of the invention, the main support, is formed from perspex and the thin-walled loading tube is formed from PTFE material. The perspex gives a smooth surface.
- Preferably the loading tube is mounted on the main support on a metal spigot at an outlet end of the funnel.
- In a still further aspect the invention provides a pack for an elongate intravascular catheter of the type comprising a tubular body with a proximal end and a distal end, the distal end adapted for reception of a medical device, the pack comprising a tray having means for releasably holding the distal end of the catheter relative to an associated catheter loading device in a cooperative juxtaposition on the tray, the loading device being operable to collapse the medical device from an expanded in-use position to a collapsed position for reception within the pod. This facilitate raid and correct loading, of a medical device within the catheter.
- Preferably the tray has a liquid retaining bath formed by recess in the tray, the bath having a depth sufficient to accommodate in a totally submerged state the distal end of the catheter and a medical device for submerged loading of the medical device into the catheter.
- In another embodiment the tray has a catheter holding channel communicating with the bath, the channel defining a pathway around the tray which supports the catheter in a loading position on the tray.
- Preferably the means for securing the catheter within the channel comprises a number of retainers spaced-apart along the channel, each retainer comprising two or more associated projections which project inwardly from opposite side walls of the channel adjacent a mouth of the channel, the projections being resiliently deformable for snap engagement of the catheter within the channel behind the projections.
- Conveniently a ramp is provided at an end of the channel communicating with the bath to direct a distal end of the catheter towards a bottom of the bath.
- In another embodiment means is provided within the bath for supporting the distal end of the catheter above the bottom of the bath. Preferably said supporting means is a step adjacent the channel.
- In another embodiment means is provided within the bath for supporting a catheter loading device for engagement with the distal end of the catheter to guide a medical device into the distal end of the catheter. Preferably said means comprises a recess in a side wall of the bath for reception of a funnel with an outlet pipe of the funnel directed towards the channel for engagement within the distal end of the catheter.
- Ideally, it will be appreciated that the device for loading the catheter with a compressible filter device such as described above may be used in conjunction with this pack. The advantage of this is that the filter device can be submerged in a saline bath during loading into the pod which ensures that air is excluded from the filter device when loading as it would obviously cause medical complications if air was introduced to the bloodstream during an angioplasty and stenting procedure.
- The tray system with the catheter distal end submerged, combined with appropriately designed catheter proximal end and standard device flushing techniques can ensure a fluid filled device is introduced to the vasculature.

- FIG. 10 are, detail plan views of retaining clip portions of the pack of FIG. 9,
- FIG. 11 is a perspective view showing a bath portion of the pack of FIG. 9, and
- FIG. 12 is a sectional view of the bath portion of the pack illustrated in FIG. 11.
- Referring to the drawings and initially to FIGS. 1 and 2 thereof, there is illustrated a catheter, indicated generally by the
reference numeral 1, for mounting acollapsible filter 2 or other collapsible medical device. The catheter has on it's free distal end apod 3 within which thefilter 2 is shown compressed in FIG. 2. Aguide wire 6 on which thefilter 2 is mounted is also illustrated in FIG. 2. - FIG. 7 shows the
collapsible filter device 2, of the type described in our Patent Application No. PCT/IE98/00093, in an expanded in-use position. Thefilter device 2 is mounted adjacent a distal end of theguidewire 6 which terminates at the distal end in aflexible spring tip 7. - The filter device can be collapsed inwardly against the
guidewire 6 for reception within thepod 3 as shown in FIG. 2. - Referring particularly to FIGS. 2, 3 and4 a the
catheter 1 comprises an outer thinwalled tube 10 of PTFE or other thin walled polymer tube surrounding an elongate tubular body forming an inner support core which in this embodiment is formed by aspring 11. The outerthin wall tube 10 projects beyond a distalfree end 12 of thespring 11 to form thepod 3. - An alternative catheter construction is shown in FIG. 4b. In this case the
catheter 1 is formed by apolymeric tube body 14 having a thin-walleddistal end portion 15 which forms thepod 3. This thin-walled pod 3 is formed by locally thinning thepolymeric tube body 14 at thedistal end 15 of thetube body 14. A still further construction is shown in FIG. 4c in which in this case the inner support core is formed frompolymeric tubing 16. - FIG. 3 also illustrates a loading device indicated generally by the
reference numeral 20, which loading device comprises asupport 21 having a funnel-shape bore 22 formed from a frusto-conical filterdevice receiving portion 25 terminating in a cylindrical portion formed by a thin wallstainless steel spigot 23 on which is mounted aloading tube 24, again of a flexible thin wall material, in this embodiment PTFE. It will be seen from FIG. 3 how theloading device 20 is inserted into thepod 3. - To use the
loading device 20, referring now specifically to FIGS. 5 and 6, thefilter 2 is connected to theguidewire 6 and is drawn through theloading device 20 where it is compressed and pulled through thespigot 23 and theloading tube 24 until it rests within thepod 3 at a proximal end of thepod 3. With theguidewire 6 held fast relative to the catheter, theloading device 20 is withdrawn leaving behind thefilter 2 which is now mounted within thepod 3 as shown in FIG. 2. It will be appreciated that thefilter device 2 will move smoothly through theloading tube 24 as theloading tube 24 is in tension during loading. - The
catheter 1 can then be delivered trans-arterially according to standard clinical practice to a deployment site. As thecatheter 1 is moved through the arteries a leading end of thepod 3 which is flexible will deflect to assist in guiding thecatheter 1 to the deployment site without damaging the artery wall. Once in position thefilter device 2 is held stationary whilst catheter body incorporating thepod 3 is retracted. When released thefilter device 2 will expand to fill the vessel. - Advantageously for use simply as a deployment catheter the thickness of the pod wall can be minimised, and consequently the crossing profile of the catheter can be minimised, as the pod does not need to be able to withstand compressive forces which would collapse the pod. When retaining the medical device and when pushing the medical device out of the pod for deployment the pod wall is in tension and so will not collapse. For loading the medical device in the pod the loading tube of the loading device projects into the pod to shield the pod from compressive forces which would collapse the pod.
- It will be appreciated that instead of having the guidewire co-axially mounted within the catheter along the full length of the catheter, the guidewire may only be co-axial with an outer free end of the catheter. In this case, the guidewire is mounted alongside the catheter and enters an inlet hole adjacent the outer free end of the catheter (typically 5-20 cm from the end of the catheter) to travel coaxially within the outer free end of the catheter. This configuration is commonly referred to as a RAPID EXCHANGE system.
- It will be appreciated that the catheter/pod assembly may be constructed with a single polymeric tubing that has an integral distal thin walled section describing the pod. This construction can be achieved by a localised moulding operation. Alternatively, a pod may be bonded to the proximal tube by way of adhesive or welding.
- The pod described in any of the constructions may be fabricated with enough longitudinal stiffness such that it can withstand compressive loading of a filter element into it. In this embodiment the delivery catheter may also be used as a retrieval catheter.
- Referring now specifically to FIGS.9 to 12, there is illustrated a pack for retaining a catheter assembly. Such a catheter assembly could be of conventional construction or may be as is illustrated, a
catheter 1 according to the present invention. - Referring to FIGS. 9 and 10 initially, the pack has a moulded
plastics tray 30 which is recessed to support the parts of a catheter such as, for example, a recess 31 to retain a conventional Y-connector with an associatedhub receiving slot 32 at one end for reception of a hub mounted at a proximal end of a catheter. Abath 33 is formed by another recess in thetray 30. A catheter mounting recess orchannel 34 extends between thehub receiving slot 32 and thebath 33. It will be noted that thechannel 34 is shaped to define a desired curve with no sharp bends and smooth transitions to facilitate loading of a catheter in situ. Thechannel 34 is provided with a number of spaced-apart retaining clips 37 illustrated in FIG. 10. Each retainingclip 37 comprises three associatedprojections 42 which project inwardly fromopposite side walls 43 of thechannel 34 adjacent an upwardly open mouth of thechannel 34. Theseprojections 42 and/or theside walls 43 of thechannel 34 are resiliently deformable for snap engagement of a tubular catheter body within thechannel 34 behind theprojections 42. A downwardly sloping ramp 44 (FIG. 12) is provided at an end of thechannel 34 communicating with thebath 33 to direct a distal end of acatheter 1 towards a bottom of thebath 33. Further recesses 39 and 40 respectively are provided to retain an adapter and a syringe for flushing thecatheter 1 with saline solution. Obviously, it will be appreciated that many other forms of apparatus could be provided. - The
bath 33 has a bottom 45 with an upwardly extendingside wall 46. It will be noted that astep 47 is provided adjacent thechannel 34 for supporting the distal end of thecatheter 1 above the bottom 45 of thebath 33 to facilitate loading of thecatheter 1 with amedical device 2. - A
recess 48 is shaped in thestep 47 for reception of theloading device 20 for thecatheter 1. When theloading device 20 is mounted in therecess 48 theloading tube 24 extends into thepod 3 of thecatheter 1 in a cooperating loading position. Lugs 49 at each side of therecess 48 engage and retain thesupport 21 in therecess 48. These lugs 49 are resiliently deformable for snap engagement of thesupport 21 in therecess 48 and to allow release of thesupport 21 from therecess 48. - A
further channel 50 for a balloon tube is also provided on thetray 30 having a number of spaced-apart retaining projections 52 (FIG. 10) to retain a balloon tube in thechannel 50. In use, thecatheter 1 is packaged on thetray 30, being mounted within thechannel 34 so it is held on thetray 30 in a position ready for loading. Saline solution is injected through thecatheter 1 to exclude air from thecatheter 1 and thebath 33 is filled with saline solution. Theguidewire 6 having thefilter 2 attached is then fed through theloading device 20 and through thecatheter 1. Air is excluded from thefilter 2 which is submerged in the saline bath and thefilter 2 is then drawn through theloading device 20 into thepod 3 at the distal end of thecatheter 1. The loading is conducted under water to prevent air entrapment in thefilter device 2 whilst loading thefilter device 2 in thepod 3 at the distal end of thecatheter 1. It will be noted that thepod 3 at the distal end of thecatheter 1 is submerged and, thecatheter 1 is held firmly on the tray in loading engagement with theloading device 20 while thefilter 2 is being loaded into thepod 3. - The invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail within the scope of the appended claims.
