STENT-GRAFT PROSTHESIS WITH PRESSURE RELIEF CHANNELS
First Claim
1. A stent-graft prosthesis comprising:
- a graft material having a tubular construction, the graft material including a proximal end, a distal end, a graft lumen extending between the proximal end and the distal end, and a central longitudinal axis;
a frame coupled to the graft material; and
a channel for relieving pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel, wherein the channel includes a channel entrance distal of the proximal end of the graft material, and a channel exit proximal of the distal end of the graft material,wherein the channel permits blood flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration.

Abstract
A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.

5. A stent-graft prosthesis comprising:
-
a graft material having a tubular construction, the graft comprising a proximal end, a distal end, a graft lumen extending between the proximal end and the distal end, and a central longitudinal axis; a frame coupled to the graft material; and a channel for relieving pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel, wherein the channel includes a channel lumen extending from a channel entrance to a channel exit, wherein the channel lumen is a portion of the graft lumen, the channel entrance is disposed through the graft material distal of the proximal end of the graft material and is configured to permit blood flow to the channel lumen, and the channel exit is disposed through the graft material distal of the channel entrance and is configured to permit blood flow from the channel lumen such that the channel permits blood flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A stent-graft prosthesis comprising:
-
a graft material having a tubular construction, the graft comprising a proximal end, a distal end, a graft lumen extending between the proximal end and the distal end, and a central longitudinal axis; a frame coupled to the graft material, the frame including at least one body stent; and a channel for relieving pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel, wherein the channel is defined between an outer surface of the graft material and an adjacent first segment of the at least one body stent to which the graft material is not attached such that the channel permits blood flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration. - View Dependent Claims (16, 17, 18, 19, 20)
