ABSTRACT:
In a method for repairing a liver laceration, a plurality of bolts of biocompatible material are provided, each of the bolts being formed with anchoring means for preventing removal of the respective bolt from the liver upon insertion of the bolt therein. At least two of the bolts are driven into the liver on opposite sides of the laceration so that head portions of the two bolts remain protruding from the liver. A suture is tied around the protruding head portions of the two bolts, thereby closing the laceration and stemming a flow of blood from the laceration. The bolts may be provided with molley type sheaths which are pushed into the liver prior to insertion of the two bolts and which are expanded at least in part by the bolts to anchor the sheaths and the bolts in the liver. The sheaths, like the bolts, are made of a biocompatible, even bioabsorbable or hemostatic, material.
