Definitions

  • FIG. 4A is a partial side view of an alternative embodiment of the wire guide and catheter of the present invention.
  • the distal portion 26 of the wire guide 20 extends distally from the port 19 at the distal end 21 of the catheter 12.
  • the wire guide 20 may be extended distally so that the cutting portion 28 is disposed distal of the port 19 and can be used to cannulate tissue as described below.
  • the tip 30 may be tapered and extend distally beyond the cutting portion 28 between about 2.5 to 25 centimeters (cm), preferably about 5 to 10 cm.
  • the cutting portion 28 may be about 0.5 to 5 cm in length.
  • the cutting portion 28 of the wire guide 20 extents externally from the lumen 14 of the catheter 12 through side ports 19a and 19b so that the cutting portion 28 extends generally axially with respect to the catheter 12. At least a portion of the distal portion 26 of the wire guide 20 may also extend distally from the port 19 of the catheter 12.
  • the port 19b may be located about 5- 20 cm proximal from the distal end 21 of the catheter 12.
  • the spacing between the ports 19a and 19b may be the same length as the cutting portion 28, or may be longer or shorter than the cutting portion 28.
  • the cutting portion 28 may be about 0.5 to 5 cm in length.
  • the port 19a may be spaced apart from the port 19b about 0.5 to about 3 cm.
  • the cutting portion 28 of the wire guide 20 may be movably disposed in the catheter 12 and configured to extend externally from the lumen 14 of the catheter 12 through a channel 19c so that the cutting portion 28 extends generally axially with respect to the catheter 12 as shown in FIGS. 5 A and 5B. Similar to the embodiments described above, the cutting portion 28 of the wire guide 20 extends external to the catheter 12 so that a stricture may be cannulated. In some embodiments having a channel 19c, the cutting portion 28 may be bowed to extend beyond the catheter 12.
  • the wire guide 20 may be re-extended through the channel 19c and in the embodiments having the ramp-like structure 43, the wire guide 20 may be redirected at an angle along the structure 43 and away from the distal end 21 of the catheter 12.
  • the wire guide 20 may have conventional dimensions and be made from conventional materials where at least some of the components are capable of conducting current.
  • the length of the wire guide 20 may range from about 40 to 480 cm.
  • An outside diameter of the wire guide 20 may range from about 0.008 to 0.05 inches.
  • the power source 27 may be turned off and in some embodiments, the connector 23 may be disconnected from the proximal portion 24 of the wire guide 20. Additional medical procedures may be conducted using the wire guide 20 in the non-energized state as a traditional wire guide.
