Abstract
The present invention relates generally to agents and devices for promoting hemostasis and tissue sealing and, more particularly, to hemostatic pads comprising bioabsorbable scaffolds that can deliver lyophilized hemostasis promoting proteins, such as fibrinogen and thrombin, to a wound site or injured organ or tissue.
Claims5

- a bioabsorbable scaffold having a wound facing surface and an opposing surface;
- and a hemostatic powder that comprises a mixture of fibrinogen and thrombin, the method comprising:
- a) wetting the scaffold with the biocompatible liquid that is not blood or plasma selected from the group consisting of an aqueous solution, normal saline, ethanol, and ethanol-water mixture;
- then
- b) contacting the scaffold with the hemostatic powder in dry form in a powder tray onto the wet scaffold and adhering at least a portion of the hemostatic powder to at least the wound facing surface of the scaffold;
