Abstract:
A bifurcated intravascular stent graft, comprising:first and second primary stent segments; a primary graft sleeve operatively coupled near a first open end thereof to the first primary stent segment, operatively coupled near a second open end thereof to the second primary stent segment, having a side opening therethrough, and forming a main fluid flow channel between the open ends of the graft sleeve; and an internal graft channel formed within the primary graft sleeve and separated from the main fluid flow channel by a partition, the internal graft channel having an inner open end within the primary graft sleeve and an outer open end communicating with the side opening of the primary graft sleeve, thereby forming at least a portion of a branch fluid flow channel between the main fluid flow channel and the side opening of the graft sleeve, wherein: the first primary stent segment and the first open end of the primary graft sleeve are adapted for engaging an endoluminal surface of a first segment of a main vessel and forming a substantially fluid-tight seal therewith; and the second primary stent segment and the second open end of the primary graft sleeve are adapted for engaging an endoluminal surface of a second segment of the main vessel and forming a substantially fluid-tight seal therewith.
