Abstract
Abstract The device of the invention is provided with a pair of patches each comprising a resilient, foldable annular frame and a piece of cloth stretched over and fixed to the frame. The patches are so arranged as to face each other across a gap and sewed together concentrically with a thread slightly inwardly of the outer circumferential edge thereof in such a manner that as the thread is pulled, the two patches are moved so as to approach each other. 1 5

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
A device for nonoperatively occluding a hole defect in an animal, comprising a pair of patches each of which comprises a flexible, foldable annular frame and a piece of cloth stretched over and fixed to the frame and which are arranged so as to be folded and inserted into a catheter having a distal end which is adapted to be brought to the defect to be occluded, and pushed out of the catheter and restored to the original annular shape having a larger diameter than the defect and to face each other across a gap, said pair of patches being sewed together adjacent the periphery of the opening of said defect by a thread in such a manner that as the thread led out of one of the patches is drawn, the patches are moved to approach each other.
Claim 2
Independent Claim
139 words
A device for nonoperatively occluding a hole defect in an animal, comprising a pair of patches each of which comprises a flexible, foldable annular frame and a piece of cloth stretched over and fixed to the frame and which are arranged so as to be folded and inserted into a catheter having a distal end which is adapted to be brought to the defect to be occluded, and pushed out of the catheter and restored to the original annular shape having a larger diameter than the defect and to face each other across a gap, said pair of patches being sewed together adjacent the periphery of the opening of said defect by a thread in such a manner that as the thread led out of one of the patches is drawn, the patches are moved to approach each other.
Claim 3
Dependent Claim
56 words
A device for nonoperatively occluding a hole defect according to claim 1, wherein the two patches are sewed with the thread along a coaxial circle a little inward of the circumferential edge of each of the patches so as to securely hold the periphery of said hole defect by the peripheries of said pair of patches.
Claim 4
Dependent Claim
36 words
A device for nonoperatively occluding a hole defect according to claim 1, wherein the end portion of the thread for sewing the patches together is led out of the central portion of one of the patches.
Claim 5
Dependent Claim
61 words
A device for nonoperatively occluding a hole defect according to claim 1, wherein shrink-preventing members are provided on that surface of one of the patches which faces the surface of the other of the patches so as to extend from a position a little inward of the outer circumferential edge of the one patch to a position near the center thereof.
