Abstract: A body tissue has oppositely disposed first and second tissue sides with an aperture extending therebetween. An apparatus for selectively permitting access through the body tissue includes a proximal balloon adapted for placement adjacent the first tissue side. A distal balloon is adapted for placement adjacent the second tissue side. An expandable support member is adapted to extend through the aperture and defines a support member lumen providing fluid communication between the first and second tissue sides. The expandable support member is attached to the proximal and distal balloons and has at least one of an inner support member lining and an outer support member cover. A support member valve is located within the support member lumen and selectively permits access through the aperture between the first and second tissue sides. A closure device is provided for permanently occluding the support member lumen.

Abstract: An intraoperative anastomosis method is described and comprises the steps of providing an intraluminal prosthesis having a first end and a second end; suturing a first vessel to a second vessel to form a vessel junction; intraluminally delivering the prosthesis so that the first end of the prosthesis is disposed within the first vessel and the second end of the prosthesis is disposed within the second vessel; and deploying the prosthesis so that the prosthesis overlaps and reinforces the vessel junction. The vessel suturing, prosthesis delivering, and prosthesis deploying steps may be performed in a single operation. Other devices, systems, and methods are described.

Abstract: An aortic stent graft and a method of deploying the aortic stent graft. The method comprises providing a tapered tubular graft having a distal end and a proximal end, providing at least one stent attached to the graft at a site adjacent the distal end of the graft, loading the graft into an introducer, inserting the introducer through an incision in the aorta, deploying the graft inside the aorta; and suturing the proximal end of the graft in place.
