Abstract
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.
