Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
A stent graft device for insertion into a lumen by an insertion catheter comprising: an expandable stent having various portions, a graft secured to said stent, a band for preventing the stent and graft from expanding, a release means for severing the band to allow the stent and graft to expand, means for retaining the stent graft in position while removing the insertion catheter from the stent graft, means for maintaining together the various portions of the stent, means for maintaining the stent graft substantially smooth as the insertion catheter is removed from the stent graft, and means for holding the front portion of the graft from folding back upon itself during deployment from the insertion catheter.
Claim 2
Dependent Claim
20 words
The stent graft device of claim 1 wherein the expandable stent has at least a first ring of multiple cells.
Claim 3
Dependent Claim
47 words
The stent graft device of claim 1 wherein the means for retaining the stent graft in position includes: a. fork means for engaging the stent, b. receiving means on the stent for receiving the fork means, and c. fork control means for retaining and moving the forks.
Claim 4
Dependent Claim
48 words
The stent graft device of claim 3 wherein the fork means have a "V" shape for mating with the receiving means which have a needle eye shape and the fork control means are wires attached to the fork means and extend from both sides of the insertion catheter.
Claim 5
Dependent Claim
35 words
The stent graft device of claim 2 wherein the means for maintaining together the various portions of the stent maintains both the various cells and the rings joined at the tangent points of the cells.
Claim 6
Dependent Claim
32 words
The stent graft device of claim 1 wherein the means for maintaining the stent graft substantially smooth includes both the means for retaining the stent graft in position and the insertion catheter.
Claim 7
Dependent Claim
56 words
The stent graft device of claim 2 wherein the means for holding the front portion of the graft from folding back upon itself includes a second set of rings having smaller cells than the first rings and connected to the cells at a position where each individual cell is farthest from the cell adjacent to it.
Claim 8
Dependent Claim
30 words
The stent graft device of claim 1 wherein the graft includes at least two components that are to be combined with both components at least partially supported by the stent.
Claim 9
Dependent Claim
25 words
The stent graft of claim 8 wherein the means for retaining the stent graft in position also has a means for combining the two components.
Claim 10
Dependent Claim
52 words
The stent graft of claim 9 wherein the means for combining the two components includes: a. a magnetic element attached to the a portion of the insertions catheter, b. part of the means for retaining the stent graft in position, and c. a flexible element of the portion of the insertion catheter.
Claim 11
Dependent Claim
16 words
The stent graft of claim 1 wherein at least a portion of the graft is bifurcated.
Claim 12
Dependent Claim
36 words
The stent graft of claim 1 wherein the means for maintaining together the various portions of the stent maintains the length of the stent in its compressed condition and in its expanded condition substantially the same.
