Abstract
Abstract A deployment catheter for deploying a tubular endoluminal vascular prosthesis includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy the prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. In one embodiment, a reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section. In another embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central-core.
