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 extend 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.

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 and extending through tissue overlying the vessel, duct or lumen, said system comprising a closure device and a location detector, said location detector being arranged for introduction into the puncture to provide a perceptible signal indicative of the location of the wall of the vessel, duct or lumen, whereupon a desired position for said closure with respect to the vessel, duct or lumen may be determined, said location detector comprising means for insertion in the puncture tract to a position at which the fluid within the vessel, duct or lumen is enabled to flow from the interior thereof into said location detector to provide said perceptible signal, said closure device being arranged to be positioned within a portion of the puncture in accordance with said desired position to enable the effective sealing of the puncture by said closure device.
