Graft deployment system

A deployment system for deploying a bifurcated prosthesis at the junction of a main vessel and first and second branch vessels, comprising:

• a delivery catheter having an inner core, an outer sheath and a distal tip that is coupled to the inner core, the inner core being slidably engaged within the outer sheath;
• and
• a bifurcated prosthesis having a main body section with proximal and distal ends, and first and second branch sections at the proximal end of the main body section, wherein the main body section is held in a radially compressed state by a first peelable cover, the first branch section is held in a radially compressed state within a first tubular cover and the second branch section is also held in a radially compressed within a second tubular cover.

A straight tube graft deployment system, comprising:

• an elongate, flexible catheter body, having a proximal end and a distal end and comprising an outer sheath and an inner core that is axially moveable with respect to the outer sheath;
• a first graft restraint comprising a first peelable cover for restraining at least a first portion of a straight tube graft;
• wherein the first peelable cover is coupled to a first release element and wherein the first graft restraint is positioned within the catheter body in a graft loaded position.

The method of claim 30, wherein the step of expanding at least a portion of the prosthesis includes expanding the distal portion of the prosthesis.

The method of claim 31, further comprising the step of expanding a proximal portion of the prosthesis from a radially compressed state within the deployment system to a radially expanded state within the vessel by proximately retracting a second release element so as to tear a second peelable cover.
