Abstract
A system for implanting a prosthesis includes a control lumen and a nose cone affixed at a distal end of the control lumen. At least one supporting wire is affixed at one end, is substantially parallel to a major axis of the control lumen and is free at an opposite end, wherein the free end of at least one of the supporting wires is arcuate. Alternatively, a system for implanting a prosthesis includes at least one suture extending from a nose cone affixed to a distal end of a control lumen. The suture extends from the nose cone to a proximal end to a stent graft extending about the control lumen and from the stent graft to a fixed location on the control lumen. The suture is releasable from the stent graft by remote activation, whereby the suture separates from the nose cone to thereby deploy the stent graft.

51. A system for implanting a prosthesis, comprising:

58. A method for implanting a prosthesis, comprising the steps of:
-
a) delivering a stent graft through an artery to an aneurysm site of a patient, the stent graft being radially constrained by an inner sheath and supported at least in part by a control lumen, the stent graft further being longitudinally constrained by at least one supporting wire extending from a nose cone, from the control lumen or from an outer control tube extending about and slideable along the control lumen, wherein the free end of at least one of the supporting wires is arcuate and extends through a loop within a proximal end of the stent graft; b) partially retracting the inner sheath from the stent graft, whereby the supporting wire at least partially restricts longitudinal movement of the proximal end of the stent graft until the proximal end of the stent graft is secure within the artery to thereby prevent rotation of a portion of the proximal end of the stent graft at an inferior portion of the artery; c) retracting the inner sheath; and d) retracting the supporting wire, thereby removing the supporting wire from the loop and deploying the stent graft within the artery at the aneurysm site in the patient. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76)

77. A method for implanting a prosthesis, comprising the steps of:
-
a) delivering a stent graft through an artery to an aneurysm site in a patient, the stent graft being radially constrained by an inner sheath and supported at least in part by a control lumen, the stent graft further being constrained by at least one suture extending from a nose cone at a distal end of the control lumen to a proximal end of the stent graft extending to a fixed location on the control lumen, the suture being releasable from the nose cone and the stent graft by remote activation; b) partially retracting the inner sheath from the stent graft, whereby the suture at least partially restricts longitudinal movement of the proximal end of the stent graft until the proximal end of the stent graft is secure within the artery, thereby preventing rotation of a portion of the proximal end of the stent graft at an inferior portion of the artery; c) activating the suture, whereby the suture is released from the nose cone and releases the stent graft; and d) retracting the inner sheath to thereby deploy the stent graft within the artery at the aneurysm site of the patient. - View Dependent Claims (78, 79, 80, 81, 83)

89. A method for implanting a prosthesis, comprising the steps of:
-
a) delivering a stent graft through an artery to a point distal, relative to the patient, of an aneurysm site of a patient, the stent graft being radially constrained by an inner sheath, and affixed to an outer control tube, and wherein the inner sheath is constrained by an introducer sheath, the stent graft and the inner sheath each including at least one radiopaque marker on superior portions of the stent graft and the inner sheath, the radiopaque markers being separated along a major longitudinal axis of the inner sheath; b) advancing the inner sheath, the stent graft and the outer control lumen beyond the introducer sheath until the stent graft spans the aneurysm site of the patient; c) partially retracting the inner sheath from the stent graft, whereby the radiopaque marker of the stent graft overlaps to the radiopaque marker of the inner sheath; d) positioning a proximal end of the stent graft within the artery; and e) fully retracting the inner sheath to thereby fully deploy the stent graft within the artery. - View Dependent Claims (90, 91, 92, 93, 94)
