Abstract

Abstract The device is provided with two patches each composed of a fabric sheet extended over a resilient flexible annular frame. The two patches are arranged face-to-face with a gap between them and concentrically stitched to each other at a position slightly inward the outer peripher of each patch. By drawing a thread appearing on one of the patches, both patches are brought closer to each other. @(33pp Dwg.No.2/37)@.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 133 words
Device for nonoperatively occluding a defect with a pair of patches (3) to be situated on opposite sides of the defect, each patch (3) comprising a flexible, foldable frame (1) and a piece of cloth (2) stretched over and fixed to the frame (1), and in use arranged so as to face each other, characterised in that the frame (1) is annular shaped and that the patches (3) are sewed together by at least one thread (4, 4₁, 4₂) in such a manner that as the thread (4, 4₁, 4₂) leading out of one of the patches (3) is drawn, the patches (3) are moved to approach each other such that in use the defect is positioned at the central position of both patches by the thread contacting the periphery of the defect.
Claim 2
Dependent Claim 37 words
Device according to claim 1, characterized in that the two patches (3) are sewed with the thread(s) (4, 4₁, 4₂) along a coaxial circle a little inward of the circumferential edge of each of the patches (3).
Claim 3
Dependent Claim 38 words
Device according to claim 1 or 2, characterized in that the end portion of the thread(s) (4, 4₁, 4₂) for sewing the patches (3) together is led out of the central portion of one of the patches (3).
Claim 4
Dependent Claim 55 words
Device according to claim 3, characterized in that the opposite ends of the thread (4) are drawn out of the central portion of one of the patches (3) and that a further thread (19) is coiled around the portions of the thread (4) which lie adjacent to the central portion of the other patch (3).
Claim 5
Dependent Claim 63 words
Device according to one of claims 1 to 4, charac terized in that shrink-preventing members (5) are provided on the surface of one of the patches (3) 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.
