Bifurcated/branch vessel prosthesis
First Claim
1. A prosthesis comprising a stent graft having a proximal end, a distal end, a tubular wall defining a main lumen therethrough, at least one fenestration in the wall and at least one tube extending from the fenestration into the main lumen and in fluid communication with the main lumen, whereby an extension leg stent graft can be deployed from a branch vessel into the fenestration or from the main lumen into the branch vessel and into the tube to seal into the tube.

Abstract
A stent graft has a tubular wall (1) defining a main lumen with at least one fenestration (15) in the wall. A tube (17) extends from the fenestration into the main lumen and is in fluid communication with the main lumen. An extension leg stent graft can be deployed from a branch vessel into the fenestration to seal into the tube. A flared guide (89) associated with the fenestration can be provided interiorly or exteriorly. There is also disclosed a bifurcated intraluminal prosthesis having a body (1), a first leg (7) and a second leg (17), the first leg extending from the body and the second leg extending into the body.

- 14. A prosthesis comprising a stent graft including a substantially tubular body portion providing a body fluid flow path, a first tubular leg extending from the body portion providing a first leg fluid flow path in communication with the body fluid flow path, an aperture in the tubular body portion adjacent the first tubular leg and a second tubular leg extending from the aperture into the tubular body portion, thereby providing a joining socket for a second leg extension and a second leg fluid flow path in communication with the body fluid flow path.
