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 extending through the proximal tube section and beyond the distal end;
a central core, extending through the intermediate tube; and
a cap attached to the central core;
wherein the central core is rotationally linked 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.

8. An endoluminal graft deployment catheter, comprising:
-
an elongate flexible body, having a proximal end and a distal end;
a proximal outer tube section, having a proximal end and a distal end;
a distal outer tube section, having a proximal end and a distal end, the proximal outer tube section being rotationally linked to the distal outer tube section; and
a central core, extending through the proximal and distal outer tube sections;
wherein the proximal and distal tube sections define a prosthesis cavity therein for carrying a prosthesis; and
axial separation of the proximal tube section from the distal tube section opens the cavity to release the prosthesis. - View Dependent Claims (9, 10, 11, 12)

13. An endoluminal graft deployment catheter, comprising:
-
an elongate, flexible body, having a proximal end and a distal end;
a proximal outer tube section having a proximal end and a distal end;
a distal outer tube section, having a proximal end and a distal end;
a central core, extending between the proximal outer tube section and the distal outer tube section, wherein at least one of the proximal outer tube section and the distal outer tube section is axially moveable between a first position in which the proximal outer tube section and the distal outer tube section are adjacent each other, and a second position in which the proximal outer tube section and the distal outer tube section are spaced apart, the outer tube section and the distal outer tube section forming a junction when in the first position; and
a reinforcing element carried by the catheter and spanning the junction. - View Dependent Claims (14)
