ABSTRACT:
Guidewire exit ramp members that may be placed over a tubular member having a guidewire lumen, which longitudinally extending and laterally accessible, and methods of use. The guidewire exit ramp member can be placed to force a guidewire loaded through the lumen in a first direction to be forced out of the lumen via an opening, slit or channel. The guidewire exit ramp member, in an illustrative embodiment, takes the form of a relatively short member having a proximal portion and a distally extending flap. The flap may be designed to enter and remain in a longitudinally accessible guidewire lumen. Combinations of such ramp members and device shafts having longitudinally extending laterally accessible guidewire lumens are also disclosed, as are methods for securing such combinations together. A method of backloading a guidewire into a catheter while causing lateral exit of the guidewire at a desired location is also shown.
