Abstract

An insertion tool and method for easily inserting a guide wire into a guide wire lumen of a catheter, particularly a rapid exchange catheter, for use in an endoscope. The insertion tool includes a main body (602) having a main lumen and a funnel-shaped extension (604) having a funnel lumen that merges with the main lumen. The funnel lumen has a first large opening (610) and a second smaller opening aligned with the guide wire lumen of the catheter such that, when the catheter is disposed in the main lumen, the guide wire may be easily inserted into the large opening of the funnel-shaped extension and into the guide wire lumen of the catheter. The insertion tool may further include a longitudinal slot (612) in the funnel-shaped extension and/or main body to allow removal of the guide wire from the insertion tool while the guide wire remains in the guide wire lumen of the catheter.

Claims (23)

1. An insertion tool for use in inserting a guide wire into a guide wire lumen of a catheter for use in a lumen of an endoscope, the insertion tool comprising:
a main body having a main lumen extending therethrough, the main lumen sized to accommodate the catheter therein; and a funnel-shaped extension connected to and disposed adjacent to the main body, the funnel-shaped extension having a funnel lumen extending therethrough, the funnel lumen having a first opening and a second opening, the first opening sized larger than the guide wire, the second opening positioned and sized to communicate with the guide wire lumen of the catheter when the catheter is disposed in the main lumen such that the guide wire may be easily inserted into the first opening of the funnel lumen and into the guide wire lumen of the catheter.
2. An insertion tool as in claim 1, wherein the catheter includes a longitudinal slot providing access to the guide wire lumen, the insertion tool further comprising a means for maintaining alignment between the funnel lumen and the slot of the catheter.
3. An insertion tool as in claim 2, wherein the alignment means comprises a tongue.
4. An insertion tool as in claim 2, wherein the alignment means comprises a non-round surface.
5. An insertion tool as in claim 2, wherein the main body and the funnel-shaped extension each include a distal portion, and wherein the distal portion of the funnel-shaped extension merges with the distal portion of the main body to define a merged section, the merged section sized to fit in the lumen of the endoscope.
6. An insertion tool as in claim 2, wherein the main body is sized to fit in the lumen of the endoscope.
7. An insertion tool for use in inserting a guide wire into a guide wire lumen of a catheter for use in a lumen of an endoscope, the insertion tool comprising:

a main body having a main lumen extending therethrough, the main lumen sized to accommodate the catheter therein; and a funnel-shaped extension integrally formed with and disposed adjacent to the main body, the funnel-shaped extension having a funnel lumen extending therethrough, the funnel lumen merging with the main lumen, the funnel lumen having a first opening and a second opening, the first opening larger than the guide wire and the second opening aligned with the guide wire lumen of the catheter, such that, when the catheter is disposed in the main lumen, the guide wire may be easily inserted into the first opening of the funnel lumen and into the guide wire lumen of the catheter.
8. An insertion tool as in claim 7, wherein the catheter includes a longitudinal slot providing access to the guide wire lumen, the insertion tool further comprising a tongue disposed in the main lumen, the tongue sized to fit in the slot of the catheter such that the tongue maintains alignment between the funnel lumen and the slot of the catheter.
9. An insertion tool as in claim 7, wherein the catheter includes a longitudinal slot providing access to the guide wire lumen, the insertion tool further comprising a non-round surface in the main lumen, the non-round surface engaging a non-round surface extending along a portion of the catheter such that the engaging surfaces maintain alignment between the funnel lumen and the slot of the catheter.
10. An insertion tool as in claim 7, further comprising a longitudinal slot in the main body to allow removal of the guide wire from the insertion tool while the guide wire remains disposed in the guide wire lumen of the catheter.
11. An insertion tool as in claim 7, further comprising a longitudinal slot in the funnel-shaped extension to allow removal of the guide wire from the insertion tool while the guide wire remains disposed in the guide wire lumen of the catheter.
12. An insertion tool as in claim 7, wherein the main body and the funnel-shaped extension each include a distal portion, and wherein the distal portion of the funnel-shaped extension merges with the distal portion of the main body to define a merged section, the merged section sized to fit in the lumen of the endoscope.
13. An insertion tool as in claim 7, wherein the catheter includes a longitudinal slot providing access to the guide wire lumen, the insertion tool further comprising a means for maintaining alignment between the funnel lumen and the slot of the catheter.
14. A method of inserting a guide wire into a guide wire lumen of a catheter for use in a lumen of an endoscope, comprising the steps of:

providing an insertion tool comprising a main body having a main lumen extending therethrough and a funnel-shaped extension having a funnel lumen extending therethrough;
placing the insertion tool on the catheter such that the catheter extends through the main lumen; and inserting the guide wire through the funnel of the insertion tool and into the guide wire lumen of the catheter.
15. A method of inserting a guide wire as in claim 14, wherein the insertion tool includes a distal merged section, further comprising the steps of:
prior to inserting the guide wire, advancing the insertion tool along the catheter;
and inserting a portion of the merged section into the lumen of the endoscope.
16. A method of inserting a guide wire as in claim 15, wherein the merged section is inserted into the lumen of the endoscope a sufficient distance to open a valve disposed therein, thereby permitting unhindered longitudinal movement of the catheter therethrough.
17. A method of inserting a guide wire as in claim 16, further comprising the step of sliding the insertion tool proximally along the catheter, thereby removing the merged section from the lumen of the endoscope while the guide wire remains disposed in the guide wire lumen of the catheter.
18. A method of inserting a guide wire as in claim 14; further comprising the steps of:
prior to inserting the guide wire, advancing the insertion tool along the catheter;
and inserting a portion of the main body into the lumen of the endoscope.
19. A method of inserting a guide wire as in claim 18, wherein the main body is inserted into the lumen of the endoscope a sufficient distance to open a valve disposed therein, thereby permitting unhindered longitudinal movement of the catheter therethrough.
20. A method of inserting a guide wire as in claim 19, wherein the insertion tool includes a longitudinal slot in the main body, further comprising the step of removing the guide wire from the insertion tool through the slot while the guide wire remains disposed in the guide wire lumen of the catheter.
21. A method of inserting a guide wire as in claim 14, wherein the insertion tool includes a longitudinal slot, further comprising the step of removing the guide wire from the insertion tool through the slot while the guide wire remains disposed in the guide wire lumen of the catheter.
22. A re-insertion tool having a lumen therein for re-inserting a proximal portion of a guide wire into a channel of a catheter when the catheter and a distal portion of the guide wire are disposed in a lumen of an endoscope, wherein the tool has an outside diameter greater than an inside diameter of the lumen of the endoscope, and the lumen of the tool has an inside diameter sized to accommodate the catheter, but less than the inside diameter of the lumen of the endoscope.
23. A re-insertion tool as in claim 22, wherein the tool further includes a keel sized to fit in the channel of the catheter.
