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.
