Collapsible hemostatic plug

摘要

A hemostatic plug for sealing wounds in blood vessels comprising a tubular or spring-like body capable of buckling or collapsing upon application of a threshold axial force and having a fretted distal end. A collapsed portion of the plug lodges into the tissue tract and thus acts as a foothold allowing the plug to maintain continuous pressure on the puncture site necessary for a quick effective closure of the wound. Furthermore, collapse of the plug minimizes the chance of arterial penetration.
