Abstract:
1. A method of deploying a bifurcated prosthesis in a patient's vasculature, comprising: supporting the bifurcated prosthesis with a deployment catheter; advancing at least a distal end portion of the deployment catheter and the prosthesis through a first access site in a first vessel in the patient's vasculature to a bifurcation region of the patient's vasculature; positioning a main body portion of the bifurcated prosthesis in a main vessel; positioning a first branch portion of the bifurcated prosthesis in a first branch vessel, a diameter of the first branch portion being smaller than a diameter of the main body portion; positioning a second branch portion of the bifurcated prosthesis in a second branch vessel, wherein the first and second branch vessels branch off the main vessel, a diameter of the second branch portion being smaller than the diameter of the main body portion; releasing a main body portion of the bifurcated prosthesis from a main body restraint so that the main body portion of the bifurcated prosthesis expands in the main vessel; and withdrawing the main body restraint from the patient's vasculature through a second access site in a second vessel, wherein the second access site is at a different location than the first access site.
