ABSTRACT:
A system, a closure, and method of use for sealing a percutaneous puncture in a blood vessel. The puncture includes an opening in the vessel wall and a tract leading to the opening. The system includes an introducer sheath and associated positioning device, a hemostatic puncture closure, and a deployment instrument. The positioning device enables the introducer sheath to be positioned at a desired position within the vessel. The deployment instrument includes a tubular carrier holding the closure. The closure comprises a rigid, e.g., radio-opaque, anchor, a compressed collagen plug, and a thin filament connecting the two in a-pulley-like arrangement. The instrument and introducer are used to introduce the closure into the puncture, with the anchor located within the artery and with the collagen plug within the puncture tract. A locking member is provided to hold the closure in place at its operative position, whereupon hemostasis occurs rapidly, thereby sealing the puncture.
