GUIDE CATHETERS WITH GUIDEWIRE DEFLECTION FEATURES

摘要

A guide catheter system for use in treating the sinus cavity or Eustachian tube is described. The system includes a guide catheter that has a proximal end and a distal end and an elongate shaft between the proximal end and the distal end and a guidewire. The guide catheter includes a deflection feature on a distal tip of the distal end for deflecting the guidewire at a predetermined angle.
