Abstract

A self-expanding stent-graft provided in a diametrically compacted state for implantation and retained preferably by a constraining sheath, useful for the temporary or permanent repair of injured, partially or entirely transected body conduits including blood vessels. It may be used under direct visualization to quickly stop or substantially reduce loss of blood from such damaged vessels and to quickly re-establish perfusion distal to the injury site. The device would typically be implanted under emergency room conditions but also be used in field situations by trained medical technicians. After an end of the device is inserted into a blood vessel through the injury access, deployment preferably initiates from the device end in a direction moving toward the middle of the length of the device by directionally releasing the constraining sheath. In a preferred embodiment, the two opposing ends of the device are individually deployable from the compacted, small diameter intended for insertion into a vessel, to the larger diameter at which they fit interferably into a portion of the vessel.

Claims

1. An intraluminal device comprising a self-expanding stent having first and second ends, said device provided with a covering over at least a portion of the stent, said first and second ends having a compacted state for insertion into a body conduit and a radially expanded state, said first end being retained in the compacted state by a first constraining sheath individually deployable from the compacted state to the expanded state by a first release filament configured to release said first constraining sheath, and said second end being retained in the compacted state by a second constraining sheath individually deployable from the compacted state to the expanded state by a second release filament configured to release said second constraining sheath, wherein deployment is initiated at the ends of said first and second sheaths and proceeds toward a middle length portion of said first and second sheaths by the individual application of tension to the first and second release filaments directly from the vicinity of the middle length portion of the device wherein the first and second ends are individually and independently deployable, and wherein, during repair of a body conduit, the first and second ends of the device may be deployed sequentially in vivo by the application of the tension individually to the first and second release filaments over any angle within a range of angles from 90 degrees to substantially parallel to a longitudinal axis of the device.

2. An intraluminal device according to claim 1 wherein said first constraining sheath comprises an end portion that extends beyond said first end of said self-expanding stent wherein said end portion is a pointed introducer with a diameter smaller than the compacted state of the self-expanding stent.

3. An intraluminal device according to claim 1 wherein said self-expanding stent has a length and said intraluminal device incorporates an axial stiffening component along at least a portion of the length of said self-expanding stent, said axial stiffening component adapted to being removed prior to radially expanding said self-expanding stent.

4. An intraluminal device according to claim 1 wherein said intraluminal device is adapted to be manually implantable under direct visualization.

5. An intraluminal device according to claim 2 wherein said second constraining sheath comprises an end portion that extends beyond said second end of said self-expanding stent wherein said end portion is a pointed introducer with a diameter smaller than the compacted state of the self-expanding stent.

6. An intraluminal device of claim 1 wherein said device comprises nitinol.

7. An intraluminal device of claim 6 wherein said device comprises ePTFE.

8. An intraluminal device of claim 1 wherein said device comprises ePTFE.
