Patent ID: 7717953

Claim:
A method for delivering a luminal prosthesis, said method comprising: providing a delivery catheter which carries the prosthesis, wherein the prosthesis comprises a radially expansible scaffold section, at least two anchors each having a distal end coupled with a proximal end of the scaffold section, and at least one opening extending through a side wall of the prosthesis between the at least two anchors and between the scaffold and proximal ends of the anchors, wherein, when expanded, the opening defines a passage; advancing the delivery catheter to position the prosthesis at a target location in a body lumen, the target location including an Os opening from a main body lumen to a branch body lumen, wherein at least the anchors are radially constrained by a capturing structure to prevent divarication from the delivery catheter and the scaffold is not radially constrained by a structure that is separable from the delivery catheter; positioning the prosthesis so that the scaffold lies within the branch body lumen and all of the anchors extend into the main body lumen; expanding the scaffold within the branch body lumen and expanding at least two anchors so that all of the anchors extend into and in a same upstream blood flow direction within the main body lumen when expanded; and deploying a second prosthesis within the passage through the at least one opening.
