Abstract
Abstract The prostheses include an endovascular member in need of repair and a patch therefore, as well as prostheses including two or more endovascular members, such as stent-grafts, which may be assembled in situ. Components of the prostheses are held together in substantially fluid tight engagement as the result of hook and loop structures which are present on the members. The hooks engage the loops to secure the components to one another. As a result, the present invention is particularly useful for the in situ repair of damaged prostheses and for the in situ assembly of bifurcated endovascular prostheses, particularly for the treatment of abdominal aortic aneurysms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A method of repairing a damaged area of an endovascular prosthesis having a hook or loop structure and which is positioned within a body lumen, comprising the step of: attaching a patch to a tubular endovascular prosthesis, said endovascular prosthesis including a damaged area, wherein said patch has a hook or loop structure cooperative with a hook or loop structure of said endovascular member for maintaining said patch in substantially fluid tight communication with said endovascular member; wherein said patch covers said damaged area of said endovascular prosthesis; and wherein said tubular endovascular prosthesis is selected from the group consisting of grafts, stents and stent-grafts.
Claim 2
Independent Claim
105 words
A method of repairing a damaged area of an endovascular prosthesis having a hook or loop structure and which is positioned within a body lumen, comprising the step of: attaching a patch to a tubular endovascular prosthesis, said endovascular prosthesis including a damaged area, wherein said patch has a hook or loop structure cooperative with a hook or loop structure of said endovascular member for maintaining said patch in substantially fluid tight communication with said endovascular member; wherein said patch covers said damaged area of said endovascular prosthesis; and wherein said tubular endovascular prosthesis is selected from the group consisting of grafts, stents and stent-grafts.
Claim 3
Dependent Claim
26 words
The method of claim 1 , further comprising the step of delivering said patch to said endovascular member through a body lumen containing said endovascular member.
Claim 4
Dependent Claim
34 words
The method of claim 1 , wherein said patch comprises one of a hook structure and a loop structure and said endovascular member comprises the other of said hook structure and said loop structure.
Claim 5
Dependent Claim
13 words
The method of claim 1 , wherein said attaching step occurs in situ.
Claim 6
Dependent Claim
44 words
The method of claim 1 , wherein said attaching step is effected by expanding a balloon affixed to a catheter to cause said hook or loop structure of said patch to engage the other of said hook or loop structure of said endovascular member.
Claim 7
Dependent Claim
17 words
The method of claim 2 , wherein said delivery step is effected by use of a catheter.
Claim 8
Dependent Claim
18 words
The method of claim 2 , wherein said delivery step is effected by use of a balloon catheter.
