ABSTRACT:
A method and closure device for performing a routine biopsy procedure without the use of sutures or butterfly bandages. The method and closure device controls bleeding, repairs the biopsy site, reduces the likelihood of inducing excessive scarring and reduces the handling of tissue. The closure device is comprised of a syringe, a detachable needle mounted on an end portion of the syringe, a biopsy punch mounted on the syringe which is accessible when the needle is detached from the syringe, and a a circular sponge made from an absorbable foam material which swells and fills up the defect left by biopsy and an applicator for implanting the sponge into the biopsy site. The sponge is pre-formed to a diameter which approximately corresponds to the diameter of the punch which is used for excising a biopsy specimen. After a biopsy site has been anesthetized with the syringe and needle, the needle is removed to expose the biopsy punch, the specimen is excised with the punch and the sponge is implanted into the space from which the specimen was taken, A slight pressure is applied to the sponge for approximately 30 to 60 seconds to stop any excess bleeding.
