Multiple Branch Tubular Prosthesis and Methods
First Claim
1. A method of forming an opening in a tubular prosthesis in vivo comprising:
- endovascularly positioning a tubular prosthesis in a first passageway in a human body in the vicinity of a second passageway that branches from the first passageway;
positioning an imaging device in the prosthesis and locating the juncture between the first passageway and the second passageway therewith;
extending a piercing member from the imaging device to a portion of the prosthesis adjacent to the juncture; and
forming an opening in the portion with the piercing member into the second passageway.

Abstract
A tubular prosthesis having an opening formed in a side wall thereof is positioned in a first passageway in a human body with the opening facing and providing fluid flow to a first branch passageway that branches from the first passageway. A portion of the prosthesis that is in the vicinity of the juncture between the first passageway a second branch passageway is located and a second opening is formed in the located portion of the prosthesis so that the second opening faces the second branch passageway. In another embodiment, a tubular prosthesis is endovascularly delivered and positioned in a first passageway in a human body in the vicinity of a second passageway that branches from the first passageway. An imaging device, which is positioned in the prosthesis, locates the juncture between the first passageway and the second passageway after which a piercing member is advanced from the imaging device to a portion of the prosthesis adjacent to the juncture to form an opening in that portion of the prosthesis.
