Microcatheter with sleeved guidewire port

摘要

A microcatheter having a guidewire port that is positioned proximal of the distal end of the microcatheter in order to provide rapid exchange capability. The guidewire port includes provisions that permit guidewire access into a lumen of the microcatheter while providing a relatively fluid tight seal at least when the guidewire is not present in the guidewire port.
