    摘要： A method of making a hemostatic plug for placement at a site where hemostatic treatment is indicated. The method comprises rolling a sheet of a hemostatic material a plurality of turns onto a generally cylindrical forming tool to thereby produce a rolled hemostatic plug having an opening therethrough along its longitudinal axis. In addition to employing one sheet of hemostatic material having a single density to form a plug, two sheets of hemostatic material having different densities can be rolled in tandem to each other on the forming tool, with one sheet overlapping an exposed wedge portion of the other sheet. The plugs thus formed can be longitudinally compressed if subsequent longitudinal expansion is desired. A typical placement site for which the plug is preferably employed is a puncture wound wherein an entry penetration of an artery and a tissue channel leading thereto are present.

    摘要： A puncture seal device for stemming the flow of blood from a punctured blood vessel has an elongated outer sheath affixed to a generally tubular housing where the housing contains a manually actuable slide which is affixed to a rigid tubular pusher member coaxially disposed within the outer sheath. Also contained within the outer sheath in longitudinal alignment with the pusher and distally thereof is a ring-shaped plug of a hemostatic material. The assembly thus far described may be fitted over a tubular introducer or the body of a catheter and then advanced therealong until the distal end of the outer sheath is proximate a bleeding blood vessel. By actuating the pusher member, the hemostatic plug surrounding the introducer or catheter is ejected from the distal end of the outer sheath and held in abutting relationship to the bleeding blood vessel.
