Definitions
- the present invention pertains to marker bands for in-vivo radiographic visualization and medical devices that include a marker band. More particularly, the present invention pertains to marker bands that include one or more holes or slots defined therein and medical devices that include these modified marker bands with polymeric material filling the holes or slots.
- Background of the Invention A wide variety of radiopaque marker bands have been developed for intracorporal medical devices. Some of the devices that include marker bands are guidewires and catheters. Of the known marker bands and intracorporal medical devices with marker bands, each has certain advantages and disadvantages. There is an ongoing need to provide alternative designs and methods of making and using marker bands and medical devices with marker bands.
- the invention provides design, material and manufacturing method alternatives for radiopaque marker bands, and medical devices with marker bands.
- the marker bands include a body region having one or more holes or slots formed therein. The holes may desirably impact the bonding between the marker band and a catheter shaft or other suitable structure.

- Figure 8 is a perspective view of another example marker band for use with a medical device
- Figure 9 is a perspective view of another example marker band for use with a medical device.
- FIG. 1 is an example medical device 10, generally depicted as a guide catheter.
- Catheter 10 may include an elongate catheter shaft 12 having a proximal end region 14 and a distal end region 16.
- a hub 18 may be coupled to proximal end region 14.
- Example guide catheters include a tubular lubricious liner that forms a lumen therein.
- a reinforcing member extends over the liner for a selected distance from the proximal end to provide stiffness.
- the reinforcement can be a metallic braid or other means known in the art.
- Catheter 10 may also include one or more marker bands 20. Marker bands 20 may be disposed at essentially any position along shaft 12.
- medical device 10 is depicted in Figure 1 as a guide catheter, device 10 could be any other type of catheter including diagnostic or therapeutic catheters such as angioplasty balloon catheters, atherectomy catheters, stent delivery catheters, and the like, or any other suitable device.
- medical device 10 can generally include any device designed to pass through an opening or body lumen.
- medical device 10 may comprise an endoscopic device, laproscopic device, embolic protection device, guidewire (as shown in Figure 3), and the like, or any other suitable device.
- marker band 20 is intended to aid in the visualization of catheter 10 (via any number of known visualization techniques) while the medical device is in use within the body.
- the visualization techniques used rely on marker band 20 being made from or otherwise including a radiopaque material.
- Radiopaque materials are understood to be materials capable of producing a relatively bright image on a fluoroscopy screen or another imaging technique during a medical procedure. This relatively bright image aids the user of catheter 10 in determining its location.
- Some examples of radiopaque materials can include, but are not limited to, gold, platinum, platinum-iridium, palladium, tantalum, tungsten alloy, plastic material loaded with a radiopaque filler, and the like.
- Marker band 20 may be incorporated into catheter 10 by disposing marker band 20 over catheter shaft 12 during the manufacturing process. This manufacturing step may also include securing the position of marker band 20 relative to shaft 12. Securing the position of marker band 20 may be important for a number of reasons. For example, if marker band 20 is properly secured, the clinician can rely on the known position of marker band 20 in order to accurately assess the position of the remainder of catheter 10. This may include the clinician being able to know the precise location of the distal end of catheter 10 by virtue of visualizing marker band 20 and knowing how far marker band 20 is from the distal end of catheter 10. This may be critically important when catheter 10 is being used in a particular sensitive location, such as the central nervous system, because errantly positioning the catheter 10 could damage sensitive areas.
- Marker band 20 may include a number of refinements, which may provide a number of desirable features to catheter 10 and/or marker band 20 itself. These refinements may include improving the bonding between marker band 20 and shaft 12.
- marker band 20 may include one or more holes or slits 22 formed therein, as shown in Figure 2.
- holes 22 may improving the bonding of marker band 20 to shaft 12, for example, by interlocking marker band 20 with shaft 12 by including an exterior polymer layer 24.
- Interlocking may be accomplished by disposing polymer layer 24 over marker band 20, then melting and allowing polymer layer 24 to flow through holes 22 and within the space or void 26 that may exist between marker band 20 and an inner liner or shaft portion 28. Therefore, including slits 22 allows for consistent and predictable reflow of polymer layer 24 that essentially fills space 26. Once the polymer layer 24 is solidified or otherwise hardened, marker band 20 becomes locked into position. As described above, securing the position of marker band 20 may be desirable.
- the manufacturing steps that can be used to create the interlocking structure or arrangement between marker band 20 and shaft 12 may include extruding polymer layer 24 over marker band 20 and liner 28.
- Liner 28 may comprise a generally tubular shaft that may be made of a metal, metal alloy, polymer, composite material, and the like, or any other suitable material.
- liner 28 may comprise a stainless steel or nickel-titanium alloy hypodermic tube (i.e., a "hypotube"), a polytetrafluoroethylene (PTFE) liner or etched PTFE liner, or any other suitable structure.
- PTFE polytetrafluoroethylene
- polymer layer 24 may be suitably molten or sufficiently adapted to flow through holes 22 and into space 26.
- polymer layer 24 can become disposed within holes 22 and space 26 by heating polymer layer 24 as a part of the extrusion or in a separate manufacturing methodology.
- a number of other manufacturing methods may be substituted that generally result in an exterior layer becoming disposed over marker band 20, within holes 22, and under marker band 20 (i.e., between marker band 20 and liner 28).
- Including marker band 20 with holes 22 may be desirable for a number of other reasons.
- holes 22 may allow for less material to be used for securing marker band 20 to shaft 12 (and/or liner 28).
- catheter 10 can be manufactured with a decreased outer profile. Reducing the amount of material used may also increase the flexibility, which may be desirable.
- spaces 26 are formed during the manufacturing process (which can be the case in medical devices that do not include marker band 20) the outer surface of the medical device may form a corresponding outward projection or "bump".
- FIG. 3 depicts another example medical device 110, this time the distal portion of a guidewire, in order to illustrate that marker band 20 may be used with essentially any other suitable medical device including a guidewire.
- Guidewire 110 is similar to typical guidewires and may include a central core wire 130 and a polymer jacket 132 disposed over core wire 130. Marker band 20 may be disposed over core wire 130.
- Polymer jacket 132 may flow through holes 22 in marker band 20 so as to fill space 126 (which is shown larger than it would likely be in practice) and secure marker band 20.
- Figures 4-9 illustrate a number of different forms of marker band 20 that are contemplated.
- Figure 4 depicts marker band 20.
- the general form of marker band 20 and the others described below is that they include a generally tubular or cylindrical body portion 34 defining a central channel 36 and a pair of opposing ends 38a/b.
- Holes 22 are formed within body portion 34 and generally extend all the way through body portion 34 and into channel 36 so that materials (e.g., polymer layer 24) can flow therethrough and into channel 36.
- marker band 20 is made from or otherwise includes a radiopaque material.
- marker band 20 can be disposed over liner 28 (or any other portion of shaft 12) by sliding marker band 20 thereover to the desired position.
- the desired position for marker band 20 is near the distal end of the device.
- marker band 20 can be disposed at essentially any position along shaft 12.
- any number of marker bands 20 may be used, such as 1, 2, 3, 4, 5, 6, or more marker bands. If it is not practical to slide marker band 20 over shaft 12, it may be desirable to form marker band 20 from a generally flat or planar sheet of material and then wrap the material into a generally cylindrical shape (or any other suitable shape) about shaft 12. Typically there will be a relatively tight tolerance between marker band 20 and shaft 12.
- polymer layer 24 can be disposed over marker band 20. As described above, polymer layer 24 can flow through holes 22 and fill any void 26 that might otherwise be created between marker band 20 and shaft 12. Accordingly, it may be desirable to use a thermoplastic material (i.e., a material whose viscosity changes with the induction of heat), a thermoplastic-like material, a thermoset material, combinations thereof, or the like for polymer layer 24.
- a thermoplastic material i.e., a material whose viscosity changes with the induction of heat
- thermoplastic-like material i.e., a material whose viscosity changes with the induction of heat
- thermoset material i.e., a thermoset material, combinations thereof, or the like for polymer layer 24.
- suitable polymers may include polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETFE), fluorinated ethylene propylene (FEP), polyoxymethylene (POM), polybutylene terephthalate (PBT), polyether block ester, polyurethane, polypropylene (PP), polyvinylchloride (PNC), polyether-ester (for example, a polyether-ester elastomer such as AR ⁇ ITEL® available from DSM Engineering Plastics), polyester (for example, a polyester elastomer such as HYTREL® available from DuPont), polyamide (for example, DURETHA ⁇ ® available from Bayer or CRISTAMID® available from Elf Atochem), elastomeric polyamides, block polyamide/ethers, polyether block amide (PEBA, for example, available under the trade name PEBAX®), silicones, polyethylene (PE), Marlex high-density polyethylene, Marlex
- polymer layer 24 can be blended with a liquid crystal polymer (LCP).
- LCP liquid crystal polymer
- the mixture can contain up to about 5% LCP.
- polymer layer 24 may be or include a coating, for example, a lubricious, a hydrophilic, a protective, or other type of coating may be applied over portions or all of shaft 12 or other portions of catheter 10.
- Hydrophobic coatings such as fluoropolymers provide a dry lubricity which improves catheter and guidewire handling and device exchanges. Lubricious coatings improve steerability and improve lesion crossing capability.
- Suitable lubricious polymers are well known in the art and may include silicone and the like, hydrophilic polymers such as high- density polyethylene (HDPE), polytetrafluoroethylene (PTFE), polyarylene oxides, polyvinylpyrolidones, polyvinylalcohols, hydroxy alkyl cellulosics, algins, saccharides, caprolactones, and the like, and mixtures and combinations thereof. Hydrophilic polymers may be blended among themselves or with formulated amounts of water insoluble compounds (including some polymers) to yield coatings with suitable lubricity, bonding, and solubility. Some other examples of such coatings and materials and methods used to create such coatings can be found in U.S. Patent ⁇ os.
- HDPE high- density polyethylene
- PTFE polytetrafluoroethylene
- Hydrophilic polymers may be blended among themselves or with formulated amounts of water insoluble compounds (including some polymers) to yield coatings with suitable lubricity, bonding, and solub
- FIG. 4 shows that marker band 20 may include two holes 22. However, this need not be the case as other numbers are contemplated.
- Figure 5 depicts marker band 120 that includes three holes 122 formed therein. It can also be seen that the arrangement of holes 122 can also vary. For example, holes 122 are arranged in a staggered configuration about body portion 134 of marker band 120. The staggered configuration is understood to be an arrangement where no two holes 122 are radially aligned. The shape of the holes defined in the various marker bands may also vary. For example, Figures 4 and 5 depict holes 22/122 as being generally circular.
- Figure 6 shows marker band 220 having oval or pill-shaped holes 222. It can be appreciated that holes 222 may alternatively be triangular, squared, rectangular, polygonal, irregularly shaped, and the like, or have combinations of these or any other shape.
- Figure 7 is another example marker band 320 where holes or slits 322 are disposed at the ends 338a b of body portion 334. This embodiment illustrates that slits 322 can be disposed at essentially any position along marker band 320 and still have the desired effects.
- slits 322 disposed at ends 338a/b allow polymer layer 24 to flow under marker band 320 so as to improve bonding between marker band 320 and shaft 12, as described above.
- holes or slits 322 can vary in number and arrangement.
- Figure 7 depicts two pairs of holes 322 (i.e., four holes 322) at each end 338a/b that are radially aligned.
- holes 322 are also longitudinally aligned with the corresponding holes 322 on the opposite end 338a/b of marker band 320.
- these holes could alternatively be staggered radially and/or longitudinally as well as vary in number.
- Figure 8 depicts marker band 420 having three holes 422 disposed at each of ends 438a/b. Holes 422 are arranged in a staggered configuration both radially and longitudinally. It can be appreciated that other embodiments of marker bands are contemplated where the holes are staggered either radially or longitudinally, but not both.
- Figure 9 depicts another example marker band 520 that is similar to the other bands described herein except that marker band 520 include holes 522a disposed at ends 538a b and holes 522b formed medially within body 534 of marker band 520. Of course, the number, arrangement, and shape of holes 522b (as well as holes 522a) can vary as seen in the aforementioned embodiments.
