Definitions

  • Patent 5,439,445 to Kontos and U.S. Patent 5,290,247 to Crittendon all show the use of a catheter having a tubular portion that extends or telescopes beyond the guiding catheter, and an elongated manipulation/insertion wire or shaft attached to the tubular portion to manipulate the tubular portion axially - in push / pull fashion - within the guiding catheter after it has been inserted through the hemostasis valve and into the guiding catheter.
  • the Adams '562 patent suggests that the proximal manipulation/insertion wire may actually be a low-diameter tubular shaft for conducting fluid to inflate and deflate a restriction balloon that restricts movement of the tubular portion.
  • Example 4 relates to the catheter according to Example 1, wherein the proximal shaft comprises at least one additional sheath segment, wherein each of the at least one additional sheath segments is disposed around a different length of the first and second elongate members.
  • Example 8 relates to the catheter according to Example 1, wherein the first elongate member is configured to extend distally into a first portion of the tubular wall, and further wherein the second elongate member is configured to extend distally into a second portion of the tubular wall.
  • Example 15 relates to the catheter according to Example 9, wherein the proximal shaft further comprises a distal opening in fluid communication with the shaft lumen, whereby the shaft lumen is in fluid communication with an area external to the catheter and proximal to the distal tube.
  • Example 17 relates to the catheter according to Example 1, further comprising at least one support member disposed in the proximal portion of the distal tube.
  • Example 19 relates to the catheter according to Example 1, wherein the proximal shaft comprises a third elongate member.
  • Example 24 relates to the catheter according to Example 1, wherein the first length of the first and second elongate members is a portion of an entire length of the first and second elongate members such that the first sheath segment is disposed around the portion of the entire length of the first and second elongate members.
  • Example 25 relates to the catheter according to Example 1, further comprising a second sheath segment disposed around a second length of the first and second elongate members such that the second length of the first and second elongate members is disposed within the second sheath segment, wherein the proximal shaft further comprises a first shaft lumen defined by the first sheath segment and a second shaft lumen defined by the second sheath segment.
  • FIG. 1 is an environmental view showing the use of one embodiment of the subject device in a conventional guiding catheter, which is used to perform various medical procedures.
  • FIG. 8A is a side view of an extension catheter showing the junction of the proximal and distal portions, according to one implementation.
  • FIG. 18 is a perspective view of a portion of a catheter with a support membrane, according to one embodiment.
  • the positioning and configuration of the distal portions 44, 46 of the rods 30, 32 in the connection zone 42 in the wall 40 of the distal tube 14, according to any of the embodiments depicted in FIGS. 3A-4B, can enhance the kink resistance of that portion of the tube 14 as well as assisting in transmitting a distal or proximal force to the distal tube 14 in a more even fashion during use of the catheter 10.
  • FIGS. 5B-5N show that the shaft 16 can, in certain embodiments, have various configurations relating to the number, shape, and size of the elongate members.
  • the shaft 16 has a sheath segment 60 with two large rods 62, 64 and one small rod 66.
  • the sheath 60 also has lumens 70A, 70B, 70C, 70D defined within the sheath 60 as a result of the configuration of the rods 62, 64, 66.
  • Each elongate member 62, 64, 66 disposed within the sheath 60 provides additional support or reinforcement to the shaft 16 while also resulting in multiple lumens within the segment 60.
  • the opening must be large enough and/or have sufficient clearance to allow for easy insertion of various medical devices into the opening such that the devices can be urged distally through the tube and out of the opening at the distal end of the tube.
  • clearance at the opening at the proximal end of the distal tube can be optimized by minimizing the profile (by reducing the diameter, etc.) of the manipulation shaft according to various configurations as disclosed herein.
  • the tube 160 has a lumen (not shown) in fluid communication with the lumen 182 of the sheath segment 162 and further in fluid communication with the lumen 180 of the distal tube 152.
  • the tube 160 can have a lumen (not shown) that is not in fluid communication with the lumen 182 or the lumen 180.
  • the tube 160 has no lumen.
  • two marker bands 184 are positioned around the rods 156, 158.
  • the proximal end of the lumen 206 in the shaft 200 does not have an opening. That is, the proximal end of the lumen 206 is not in fluid communication with any opening at the proximal end of the shaft 200.
  • a radiopaque marker (not shown) can be located anywhere in or near the connection zone 270 (e.g. on the manipulation shaft 262 in or near the connection zone 270 or in the distal tube 260 in the connection zone 270).
  • any of the markers 274, 276, 278 can be non-cylindrical.
  • one or more of the markers 274, 276, 278 can be strips or other known configurations.
  • markers 274, 276, 278 can be helpful to indicate to the doctor or surgeon the location of the proximal end 282 of the tube 260 in relation to the guiding catheter (not shown) so that they do not insert or push the proximal end 282 past the distal end of the guiding catheter.
  • certain embodiments include a third marker 278 located at some optimal point along the tube 260 in between the other two markers 274 and 276, as shown in Figs. 2B, 12B, and 12C. As best shown in FIG. 2B, the doctor or surgeon can use this third marker 278 to track how far the tube 260 is extending beyond the guiding catheter 12. That is, the third marker 278 can be used in certain circumstances as a limit indicator.
  • the inner layer 344 also has a protective wrap (also referred to as an "extended portion,” “extension,” “distal wrap,” or “protective tip”) 348 that extends beyond the length of the outer layer 346 and, in this implementation, is wrapped around the distal end of the outer layer 346 such that the external portion (also referred to as “outer portion” or “distal portion”) of the extended portion 348 extends toward the proximal end of the tube 340 and is positioned against or adjacent to the exterior surface of the outer layer 346.
  • This configuration creates a fold 350 (also referred to herein as a "distal fold") of the extended portion 348 at the catheter tip 342 that facilitates protection of the tube layers at the tip 342.
  • the positioning of the extended portion 348 as shown ensures that the ends of the layers 344, 346 are not exposed at the distal end of the tube 340, thereby reducing the risk of delamination and the problems related thereto.
  • any of the various catheter embodiments disclosed herein can also have an outer support membrane (also referred to as a "support membrane” or “support layer”) disposed around a proximal portion of the distal tube. It is also understood that any embodiment of the support membrane as disclosed or contemplated herein can also be incorporated into any other known catheter.
  • FIG. 18 depicts one embodiment of a catheter 400 in which the distal tube 404 has a support membrane 406 disposed around and coupled to the external wall 408 of the distal tube 404.
  • the membrane 406 is disposed around a portion of the wall 408 and extends longitudinally along the length of the tube 404 such that the proximal end of the membrane 406 does not extend to the proximal end 410 of the tube 404. That is, the membrane 406 is positioned such that it is spaced from the proximal end 410 of the tube 404. Alternatively, the membrane 406 can extend to the proximal end 410 of the tube 404. According to certain implementations, the membrane 406 is disposed in the connection zone (or region) of the distal tube 404 in which the manipulation shaft 402 is coupled to the tube 402 (similar to the connection zone 42 discussed above with respect to FIG. 3A).
  • circumference membrane can utilize a high strength material while not rendering the catheter tube hindered or inoperable.
  • any of the various improved proximal end embodiments disclosed or contemplated herein can be integrated into or combined with any boosting catheter, including the boosting catheter disclosed and claimed in U.S. Application 14/210,572, entitled “Boosting Catheter and Related Systems and Methods,” which is hereby incorporated herein by reference in its entirety.
