Catheter and guide wire exchange system

摘要

A catheter and guide wire exchange system including a catheter having a guide wire lumen with a guide way extending along the length of a stiffened proximal shaft portion, and a guide member slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. The guide member may be slid along the proximal shaft portion and the guide wire in zipper-like fashion so that the guide wire is contained within the guide wire lumen distal to the guide member and with the guide wire and catheter being separated proximal of the guide member.
