Abstract
Abstract A device and method of closing an incision or puncture in a patient by inserting a vessel plug into the incision or puncture until the distal end of the vessel plug is adjacent to the outer lumen of the blood vessel or target organ so that the vessel plug does not obstruct the flow of fluid through the blood vessel or target organ. The precise positioning of the vessel plug in the incision or puncture is accomplished through the use of a balloon catheter or a cylindrical insertion assembly having a proximal plunger member associated therewith.
