Abstract

See full text

A wound closure apparatus is provided which utilizes blood fluid by activating the clotting cascade of blood fluid outside the body within a substantially enclosed sterile container then introducing, the blood fluid to the wound site to complete clotting. An apparatus for providing ways of inhibiting anticoagulating agents, and slowing fibrin clot degradation are also disclosed. Kits for practicing the invention singularly or in combination with, and/or associated with preferred procedures are also disclosed. The invention provides a clotting cascade initiation apparatus (1) including a substantially enclosed sterile containment chamber within which an aliquot of blood fluid, either autologous or from donor sources can be received, and retained. In preferred embodiments, the sterile containment chamber further includes a heparin binding agent which will bind heparin and remove it from the blood fluid. In further embodiments, the containment chamber will also include a procoagulating agent, wherein a clotting cascade can be initiated when the blood fluid is accepted into the sterile containment chamber.
