DEVICE FOR RAPID REPAIR OF BODY CONDUITS
First Claim
1. An intraluminal device comprising a self-expanding stent having at least two ends, said device provided with a covering over at least a portion of the stent, said ends having a compacted state for insertion into a body conduit and an expanded state, each of said ends having a release filament individually operable by the application of tension to cause the end to deploy from the compacted state to the expanded state.

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.

- 1. An intraluminal device comprising a self-expanding stent having at least two ends, said device provided with a covering over at least a portion of the stent, said ends having a compacted state for insertion into a body conduit and an expanded state, each of said ends having a release filament individually operable by the application of tension to cause the end to deploy from the compacted state to the expanded state.
- 25. 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 an 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 and proceeds toward a middle length portion of the device.
- 29. An intraluminal device comprising a self-expanding stent having at least one end, said device provided with a covering over at least a portion of the stent, said at least one end having a compacted state for insertion into a body conduit and an expanded state, said at least one end being retained in the compacted state by a first constraining sheath wherein said constraining sheath extends beyond said first end to incorporate an introducer of diameter smaller than said compacted at least one end.

33. A method of repairing a damaged blood vessel having proximal and distal portions comprising,
a) by direct visualization, inserting a compacted first end of a self-expanding stent-graft into the damaged blood vessel in a proximal direction; b) deploying the first compacted end of the self-expanding stent-graft to an expanded state by pulling a release filament to create a passageway from the damaged proximal portion of the blood vessel into the expanded first end of the self-expanding stent-graft. - View Dependent Claims (36)

37. A method of repairing a damaged blood vessel having proximal and distal portions comprising,
a) by direct visualization, inserting a compacted first end of a self-expanding stent-graft into the damaged blood vessel in a distal direction; b) deploying the first compacted end of the self-expanding stent-graft to an expanded state by pulling a release filament to create a passageway from the damaged distal portion of the blood vessel into the expanded first end of the self-expanding stent-graft. - View Dependent Claims (40)

41. A method of repairing a damaged blood vessel comprising,
a) by direct visualization, inserting a compacted first end of a self-expanding stent-graft into the damaged blood vessel; - and
b) deploying the first compacted end of the self-expanding stent-graft to an expanded state, thereby substantially occluding blood flow from said damaged blood vessel without recourse to pinching said stent-graft.
