Abstract
A vascular closure system includes a suture carrying portion, a plurality of needles, and an internal sealing member. The suture carrying portion is insertable through a vessel puncture of a vessel and carries first and second suture ends of at least a first suture member. The plurality of needles are extendable through a wall of the vessel adjacent to the vessel puncture and are configured to connect to the first and second suture ends. Withdrawal of the plurality of needles draws the first and second suture ends through the vessel wall. The internal sealing member is configured to advance along the first suture member through the vessel puncture and into the vessel. Applying a withdrawal force to the first and second suture ends draws the internal sealing member against an internal surface of the vessel wall to at least partially seal closed the vessel puncture.
