Abstract
Abstract A closure for sealing a percutaneous puncture in an vessel, e.g., an artery, or lumen. The puncture also includes a puncture tract in which a portion of the closure is to be located. The closure comprises an elongated rigid anchor member formed of a resorbable material, a sealing member formed of a resorbable material, e.g., compressed collagen plug, and a thin resorbable material filament, e.g., a suture, connecting the anchor member and the sealing member. The anchor member is located in the interior of the vessel, with the sealing member being located in the puncture tract. An elongated reinforcing filament or ribbon, formed of a resorbable material, is incorporated in the elongated anchor member to prevent any portion of it from breaking away in the event that the anchor is loaded beyond its breaking point.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
150 words
A closure for sealing a percutaneous puncture in a vessel or lumen of a living being, said puncture comprising a tract extending through tissue overlying the vessel, said closure comprises anchoring means, sealing means, and filament means, said closure being arranged to be inserted into the puncture tract and through the puncture in said vessel or lumen so that said anchoring means is within said vessel or lumen, said sealing means is within said puncture tract, and said filament means connecting said anchoring means and said sealing means, said anchoring means being a generally elongated member formed of a first resorbable material and including reinforcing means of a second resorbable material which has a higher tensile strength than said first material, said reinforcing means extending along substantially the length of said anchoring means and fixedly secured thereto to prevent said anchoring means from breaking apart and separating from said closure.
Claim 2
Dependent Claim
150 words
