ABSTRACT:
A plug and method for controlling bleeding and repairing a circular wound caused by the excising of a specimen of skin from a patient with a biopsy punch. The plug is a cylindrical porous sponge made from a gelatin material which, when implanted into a wound, swells, absorbs blood and is completely absorbed by the patient with little tissue reaction. By completely filling the bleeding site, the plug promotes healing without the necessity of suturing. In the first aspect of the invention, a sterile cylindrical plug is provided having about the same diameter as the biopsy punch used for excising the specimen. In a second aspect of the invention, after a specimen has been excised with a biopsy punch, the cylindrical plug is cut from a pad of the gelatin material with the same punch and implanted into the wound.
