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.
