LARGE BORE CLOSURE DEVICE AND METHODS

摘要

A vascular closure system includes a body portion (12), an anchor (60,62), a suture carrying portion (16), and a plurality of needles (18). The body portion has a distal end surface (52). The anchor is positionable through a vessel puncture in a vessel wall of a vessel. The anchor defines a vessel contact surface, wherein withdrawal of the anchor captures a portion of the vessel wall between the vessel contact surface and the distal end surface. The suture carrying portion is positionable through the vessel puncture and carries at least one suture member. The plurality of needles extend through the portion of the vessel wall adjacent to the vessel puncture and are configured to connect to the at least one suture member. Withdrawal of the plurality of needles through the portion of the vessel wall positions the at least one suture member through the portion of the vessel wall.
