Abstract
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.
Claims16
A balloon catheter, comprising:
- an elongate shaft having a proximal end and a distal end, and defining an inflation lumen therethrough;
- a balloon connected to the shaft at the distal end;
- and
- a guidewire tube disposed proximate and externally of the distal end of the shaft, the tube having a proximal end and a distal end, the distal end being disposed proximally of the distal end of the balloon, and wherein the shaft at least partially surrounds the guidewire tube.
A method of providing access to a vessel side branch from a location proximal of an inflated balloon, comprising the steps of:
- providing a balloon catheter including a shaft having a proximal end and a distal end, and a balloon assembly disposed proximate the distal end of the shaft, the balloon assembly having a proximal end, a distal end and a side;
- defining a passage extending distally into the balloon assembly such that the passage has a first opening proximate the proximal end of the balloon and a more distally disposed second opening at the side of the balloon assembly;
- and
- disposing the balloon assembly in a vessel such that the balloon assembly is disposed adjacent a side branch vessel opening such that the second opening is adjacent the side branch vessel opening.
