Abstract
Apparatus and methods are provided for use in sealing a vascular puncture site. The invention comprises an introducer sheath with an integrated closure component. The closure component includes an advanceable resilient spring clip with an expanded delivery configuration in which opposing sides do not contact one another, and an unstressed deployed configuration, in which opposing sides close towards one another. The clip is advanced along the sheath until it pierces opposing sides of a vessel wall at a puncture site. The sheath then is withdrawn, thereby causing the clip to resiliently return to its unstressed deployed configuration and draw opposing sides of the puncture together to seal the wound.
