<p>A puncture seal device (32) for stemming the flow of blood from a punctured blood vessel (150) comprises an elongated outer sheath (40) affixed to a generally tubular housing (30) where the housing contains a manually actuable slide (48) which is affixed to a rigid tubular pusher member (48) 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 (44). The assembly thus far described may be fitted over a tubular introducer or the body of a catheter (18) 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 (42) and held in abutting relationship to the bleeding blood vessel.</p> |
