Abstract
Abstract A method for deploying an endoluminal prosthesis by introducing into a bifurcated vessel a sheath introducer having therein a bifurcated graft with a primary and contralateral limb. The contralateral limb being radially retained independent of the sheath introducer. The graft being positionable by an insertion catheter. When the graft is in position within the vessel, a retaining device about the contralateral limb is broken and the graft takes the shape of the vessel.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
61 words
A method of reloading a graft into a sheath introducer, comprising: providing a graft having a distal spring portion; providing a sheath introducer including a spool apparatus having a hand crank, wherein the spool apparatus includes a plurality of suture loops connected to the distal spring portion; rotating the hand crank, thereby collapsing the distal spring portion into the sheath introducer.
Claim 2
Independent Claim
61 words
A method of reloading a graft into a sheath introducer, comprising: providing a graft having a distal spring portion; providing a sheath introducer including a spool apparatus having a hand crank, wherein the spool apparatus includes a plurality of suture loops connected to the distal spring portion; rotating the hand crank, thereby collapsing the distal spring portion into the sheath introducer.
Claim 3
Dependent Claim
20 words
The method of claim 1 , wherein the hand crank is rotated in a counterclockwise direction during the rotating step.
Claim 4
Dependent Claim
11 words
The method of claim 1 , further comprising: performing an angiogram.
Claim 5
Independent Claim
98 words
A method of positioning a bifurcated graft within a contralateral iliac vessel, comprising: providing a bifurcated graft housed within a sheath introducer, wherein the graft includes a contralateral limb and a primary limb; deploying firstly the primary limb of the graft from the sheath introducer into the aorta; and deploying secondly the contralateral limb from the sheath introducer after the sheath introducer has been withdrawn past a graft junction of the bifurcated graft such that the contralateral limb is directed downward into the contralateral iliac vessel, wherein the contralateral limb is radially retained independent of the sheath introducer.
Claim 6
Independent Claim
98 words
A method of positioning a bifurcated graft within a contralateral iliac vessel, comprising: providing a bifurcated graft housed within a sheath introducer, wherein the graft includes a contralateral limb and a primary limb; deploying firstly the primary limb of the graft from the sheath introducer into the aorta; and deploying secondly the contralateral limb from the sheath introducer after the sheath introducer has been withdrawn past a graft junction of the bifurcated graft such that the contralateral limb is directed downward into the contralateral iliac vessel, wherein the contralateral limb is radially retained independent of the sheath introducer.
