Methods of implanting a prosthesis and treating an aneurysm
First Claim
1. A method of implanting a prosthesis in a patient at a treatment site, comprising the steps of:
- a) advancing an outer catheter of a prosthesis delivery system in the patient distal to the treatment site, wherein the treatment site is a curved portion of a blood vessel;
b) advancing an inner sheath and a curved guidewire lumen of the delivery system from the outer catheter through the curved portion of the blood vessel along a guidewire while the outer catheter remains stationary relative to the patient, wherein the curved guidewire lumen is curved along the entire length of the prosthesis, whereby advancing the inner sheath and the curved guidewire lumen through the curved portion of the blood vessel causes rotation of the curved guidewire lumen and the prosthesis to thereby rotationally align the prosthesis within the treatment site;
c) retracting the inner sheath to deploy the prosthesis from within the inner sheath and at the treatment site; and
d) retracting the delivery system from the patient.

Abstract
A method of implanting a prosthesis in a patient at a treatment site includes advancing an outer catheter of a prosthesis delivery system in the patient distal to the treatment site. An inner sheath and a curved guidewire lumen of the delivery system are advanced from the outer catheter to the treatment site along a guidewire while the outer catheter remains stationary relative to the patient. Advancing the inner sheath causes rotation of the prosthesis to thereby rotationally align the prosthesis at the treatment site. The inner sheath is retracted to deploy a prosthesis from within the inner sheath and at the treatment site. The delivery system is then retracted from the patient.
