Balloon perfusion catheter

摘要

Catheter for use in catheter procedures. The catheter includes a balloon carried at the distal end of an elongate shaft. A mechanism is included for providing a generally open perfusion passage while the balloon is in an inflated state. The perfusion passage provides both branch and distal perfusion. A mechanism is secured against the balloon for supporting the perfusion passage while the balloon is in an inflated state, and a mechanism is provided for retaining the balloon shape under pressure.
