Guide wire insertion and re-insertion tools and methods of use
First Claim
1. A method of inserting a guide wire into a guide wire lumen of a catheter for use in a lumen of and endoscope, comprising the steps of:
- providing an insertion tool comprising a main body having a main lumen extending therethough 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.

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 having a main lumen and a funnel-shaped extension having a funnel lumen that merges with the main lumen. The funnel lumen has a first large opening 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. Also, a re-insertion tool and method for re-inserting a guide wire into a channel of a catheter. The re-insertion tool is particularly useful in combination with an endoscope and an SOE catheter disposed therein.

13. A method of inserting a guide wire into a guide wire lumen of a catheter comprising the steps of:
-
providing an insertion tool having a main lumen sized to receive the catheter and a secondary lumen which intersects the main lumen, the secondary lumen having a first end and a second end, the secondary lumen having a greater cross sectional area at the first end than at the second end, wherein the second end of the secondary lumen intersects the main lumen;
providing an alignment mechanism adjacent to the main lumen that is adapted to engage the catheter when the catheter is inserted in the main lumen, the alignment mechanism adapted to create a particular relative radial alignment of the catheter with respect to the insertion tool, wherein, when the catheter is in the particular relative radial alignment the second end of the secondary lumen is adjacent the guide wire lumen of the catheter;
placing the insertion tool such that a catheter is received in the main lumen; and
inserting the guide wire through the secondary lumen and into the guide wire lumen of the catheter.

14. A method of manipulating a guide wire comprising:
-
providing a guide wire insertion tool, the insertion tool having a receiving location for receiving the guide wire and a feeding location for feeding the guide wire into a guide wire lumen of a catheter;
providing a guide wire locking tool adapted to couple to the catheter and having a locking receiver at which a guide wire may be laterally inserted and axially secured;
placing the guide wire insertion tool relative to the catheter such that the feeding location is in a place allowing the guide wire to be fed into the guide wire lumen;
inserting the guide wire at the receiving location, through the guide wire insertion tool, out of the feeding location and into the guide wire lumen; and
securing the guide wire at a fixed axial location with respect to the catheter using the guide wire locking tool. - View Dependent Claims (15, 16, 17, 18, 19, 20)
