Abstract
Abstract An aneurism patch apparatus for treating an aneurism formed in a vessel includes a vessel interface side and an opposing non-interface side. A patch is formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurism. The interface side of the patch is configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth. The adherence maintains a fixed position of the patch relative to the aneurism mouth.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A method for treating an aneurism, comprising: providing a patch including a vessel interface side and an opposing non-interface side, the patch being formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurism, the interface side of the patch being configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth, and wherein the patch includes an aperture for communication with the aneurism; introducing the patch through the vessel in the stowed state; positioning the patch at least partially adjacent to the aneurism so that the aperture is substantially adjacent to the mouth of the aneurism; deploying the patch from the stowed state to the deployed state; and forming an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth.
Claim 2
Independent Claim
164 words
A method for treating an aneurism, comprising: providing a patch including a vessel interface side and an opposing non-interface side, the patch being formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurism, the interface side of the patch being configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth, and wherein the patch includes an aperture for communication with the aneurism; introducing the patch through the vessel in the stowed state; positioning the patch at least partially adjacent to the aneurism so that the aperture is substantially adjacent to the mouth of the aneurism; deploying the patch from the stowed state to the deployed state; and forming an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth.
Claim 3
Dependent Claim
18 words
The method of claim 1, wherein the adherence maintains a position of the patch relative to the aneurism.
Claim 4
Dependent Claim
25 words
The method of claim 1, further comprising: applying a low pressure source to the aneurism through the aperture of the patch to evacuate the aneurism.
Claim 5
Dependent Claim
13 words
The method of claim 3, further comprising: at least partially collapsing the aneurism.
Claim 6
Dependent Claim
35 words
The method of claim 1, further comprising: delivering adhesion material to an area between the vessel wall and the interface surface of the patch at least partially after the patch is in the deployed state.
Claim 7
Dependent Claim
19 words
The method of claim 2, wherein the patch is passively activated from the stowed state to the deployed shape.
Claim 8
Dependent Claim
19 words
The method of claim 2, wherein the patch is actively deployed from the stowed state to the deployed shape.
Claim 9
Dependent Claim
26 words
The method of claim 2, wherein at least a portion of the patch is made of a material that provides passive deployment to the deployed state.
Claim 10
Dependent Claim
26 words
The method of claim 2, wherein at least a portion of the patch is made of a material that provides active deployment to the deployed state.
