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.

Abstract: A device for retaining a graft on an artery, comprising a first part for contacting the graft and a second part for contacting the artery when the device is pierced radially through the graft and the artery wall, the first and second parts being connected by a resilient member, wherein the resilient member biases the first and second parts towards each other into a retaining configuration such that in use the artery and the graft are retained together between the first and second parts of the device, and wherein the first and second parts are moveable into an open configuration in which they are further apart than in the retaining configuration to enable the device to be conveyed along an artery.
