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.

Claims

1. A device for nonoperatively occluding a defect characterized by a pair of patches, each comprising a flexible, foldable annular frame and a piece of cloth stretched over and fixed to the frame are arranged so as to face each other and sewed together 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.

2. The device for nonoperatively occluding a defect described in claim 1 and characterized by the two patches being sewed with the thread along a coaxial circle a little inward of the circumferential edge of each of the patches.

3. The device for nonoperatively occluding a defect described in claim 1 and characterized by the end portion of the thread for sewing the patches together being led out of the central portion of one of the patches.

4. The device for nonoperatively occluding a defect described in claim 1 and characterized by shrink-preventing members 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.
