ABSTRACT:
A device is provided for endoluminal delivery of a luminary graft. As applied in the vascular system, the device comprises a catheter configured to be advanced endovascularly to a graft location. A generally tubular temporary stent having a distal end and a proximal end is tapered and attached to the catheter at the proximal end. The temporary stent comprises helically braided thread members that expand radially outwardly to a maximum diameter in a resting state. The temporary stent terminates in discrete ends temporarily affixed to the graft at the distal end. A tubular sheath selectively and reversibly radially constrains the temporary stent. The sheath is configured to be longitudinally moveable relative the temporary stent to constrain and reconstrain the temporary stent when positioned over the temporary stent, and to release the temporary stent when withdrawn from over the temporary stent. Optionally, a perfusion balloon may be combined with the temporary stent to stabilize the graft during vascular surgical treatment.
