Stent/graft device and method for open surgical placement
First Claim
Patent Images
1. A method for open surgical repair of a damaged portion of a body vessel of a patient that has been subjected to a traumatic episode, comprising:
- surgically opening an open air pathway from an outer layer of skin to said damaged vessel portion;
positioning a stent/graft device at said surgical opening for insertion through said open air pathway, said stent/graft device having a length at least as long as a length of said damaged vessel portion undergoing repair, said stent/graft device comprising an elongated generally cylindrical stent and a graft material covering at least a portion of said stent, said device being expandable from a compressed condition having a diameter less than a diameter of the vessel to an expanded condition having a diameter at least as large as the diameter of the vessel, said stent/graft device being loaded into a sheath capable of maintaining said stent/graft device in said compressed condition;
inserting said sheath having said stent/graft device loaded therein in said compressed condition into said damaged vessel portion through said open air pathway, such that said device at least spans said damaged vessel portion length; and
removing said sheath from said stent/graft device at said site such that said stent/graft device expands to said expanded condition and engages said vessel, in a manner such that migration of said stent/graft device in said vessel is inhibited.

Abstract
A method and a stent/graft device for intraoperative repair of a damaged portion of a body vessel. The stent/graft device has a length at least as long as the length of the damaged portion of the vessel undergoing repair, and is positioned within the vessel such that the device at least spans the length of the damaged vessel portion. The stent/graft device is securely engaged with the vessel at the site of the damage in a manner such that migration of the device in said vessel is inhibited.

9. A method for open surgical repair of a damaged portion of a body vessel, comprising:
-
surgically opening an open air pathway from an outer layer of skin to said damaged vessel portion; positioning an assembly comprising a sheath and a stent/graft device at said surgical opening for insertion through said open air pathway, said stent/graft device received in said sheath in a compressed condition having a diameter less than a diameter of the vessel, and expandable therefrom to an expanded condition having a diameter at least as large as the diameter of the vessel, said stent/graft device having a length at least as long as the length of said damaged vessel portion undergoing repair, said stent/graft device comprising a plurality of axially spaced stents, and a graft material spanning axially adjacent stents and covering at least a portion of said axially adjacent stents, said assembly including a mechanism for selectively splitting said sheath for effecting expansion of said stents to the expanded condition; inserting said sheath into said damaged vessel portion through said open air pathway when said stents are in said compressed condition, such that the stent/graft device at least spans said damaged vessel portion; and splitting said sheath, thereby effecting expansion of said stents to said expanded condition such that said stent/graft device engages said vessel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for open surgical repair of a fragmented portion of a body vessel that has been subjected to a traumatic episode, comprising:
-
surgically opening an open air pathway from an outer layer of skin to said fragmented vessel portion; positioning a stent/graft device at said surgical opening for repair, the stent/graft device having a length at least as long as the length of the fragmented vessel portion undergoing repair, the stent/graft device comprising a pair of axially spaced stents, and a graft material spanning the stents, the stents being expandable from a compressed condition having a diameter less than a diameter of the vessel to an expanded condition having a diameter at least as large as the diameter of the vessel, the stent/graft device being loaded into a sheath mechanism, the sheath mechanism including one or more sheath members aligned for maintaining the stents in the compressed condition; inserting the sheath mechanism having the stent/graft device loaded therein into the fragmented vessel portion through said open air pathway, and aligning the sheath mechanism along the vessel such that the stent/graft device at least spans the fragmented vessel portion; and removing the sheath mechanism, thereby effecting expansion of the stents to the expanded condition such that the stent/graft device engages the vessel. - View Dependent Claims (18, 19, 20, 21, 22)
