A system for sealing a percutaneous puncture in a blood vessel in a living being and method of use thereof. The system includes a hemostatic closure, a blood vessel locator device for determining the position of the blood vessel via the percutaneous puncture, and a deployment instrument for deploying the closure within the puncture to seal the puncture. The vessel locator includes means for enabling blood from the vessel to flow therethrough so that the position of the vessel can be rapidly determined. Once the vessel has been located the deployment instrument, which includes a tubular carrier storing the closure, is extended into the puncture to deploy the closure. The closure basically comprises a radiopaque rigid anchor for location within the blood vessel, a compressed collagen plug for location within the puncture tract leading to the vessel, and a thin filament connecting the two in a pulley-like arrangement. The deployment instrument also includes a tamper which is used to mechanically deform the plug within the tract. Once the closure is positioned hemostasis occurs rapidly, thereby locking the closure in place.

[ What is claimed is:] [1.] A system for sealing a percutaneous puncture in the wall of a vessel, duct or lumen of a living being, the vessel, duct or lumen having a fluid therein, the puncture comprising an opening in the wall of the vessel, duct or lumen and a tract contiguous with the opening extending through tissue overlying the vessel, duct or lumen, said system comprising a deployment member, a pusher member, and a puncture closure, said closure comprising a first portion at least one extending filament portion and a filament lock, said deployment member having a portion arranged for introduction through the puncture and the opening in the wall of the vessel, duct or lumen into the interior of the vessel, duct or lumen to deploy said closure in the puncture with said first portion of said closure within the interior of the vessel, duct or lumen and with said at least one extending filament portion extending from said first portion of said closure into the puncture tract, said closure being arranged to be disposed at an operative position in the puncture sealing the puncture, said filament lock comprising a knot locatable on said at least one filament portion within the puncture tract for cooperation with a portion of said closure said knot, when in said puncture tract and when said first portion of said closure is within the interior of the vessel, duct or lumen, holding said closure at said operative position, said pusher member being adapted for insertion within the tract and slidably disposed on a portion of said closure to slide therealong to effect the positioning of said knot within the puncture tract with respect to said vessel, duct or lumen and to secure said closure in place at said operative position sealing the puncture.
