Bifurcation graft deployment catheter
First Claim
1. An endoluminal graft deployment catheter, comprising:
- a proximal outer tube section having a proximal end and a distal end;
an intermediate tube having an inside surface and an outside surface, the intermediate tube being extendable through the proximal tube section;
a central core having an outside surface, the central core being extendable through the intermediate tube;
a cap attached to the central core; and
a projection extending continuously along one of the outside surface of the central core and the inside surface of the intermediate tube and a channel extending continuously along the other of the outside surface of the central core and the inside surface of the intermediate tube;
wherein the projection and the channel are engageable so that the central core is rotationally linked to the intermediate tube at all axial positions of the central core relative to the intermediate tube.

Abstract
Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.
