GUIDE EXTENSION CATHETER WITH PERFUSION OPENINGS

摘要

A guide extension catheter 100 includes a proximal shaft 102, a distal shaft 104, and a plurality of perfusion openings 106. The distal shaft includes a jacket 118 and a helical coil structure 120 embedded in the jacket 118, the distal shaft defining a lumen. The plurality of perfusion openings are disposed though the jacket of the distal shaft between windings of the helical coil structure. The guide extension catheter provides additional back support to the guide catheter. The plurality of perfusion openings allow fluid communication between an area outside the guide extension catheter and the lumen.
