Abstract
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.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
101 words
A method for repairing a liver laceration, comprising the steps of: providing a plurality of bolts of biocompatible material, each of said bolts being formed with anchoring means for preventing removal of the respective bolt from the liver upon insertion of the bolt therein; driving two of said bolts into the liver on opposite sides of the laceration so that head portions of said two of said bolts remain protruding from the liver; and attaching a suture around the protruding head portions of said two of said bolts, thereby closing the laceration and stemming a flow of blood from the laceration.
Claim 2
Independent Claim
101 words
A method for repairing a liver laceration, comprising the steps of: providing a plurality of bolts of biocompatible material, each of said bolts being formed with anchoring means for preventing removal of the respective bolt from the liver upon insertion of the bolt therein; driving two of said bolts into the liver on opposite sides of the laceration so that head portions of said two of said bolts remain protruding from the liver; and attaching a suture around the protruding head portions of said two of said bolts, thereby closing the laceration and stemming a flow of blood from the laceration.
Claim 3
Dependent Claim
58 words
The method defined in claim 1, further comprising the steps of inserting molley sheaths into the liver, said two of said bolts being inserted into respective ones of said molley sheaths, thereby expanding at least portions of said molley sheaths to anchor said sheaths and said bolts in the liver, said sheaths being made of a biocompatible material.
Claim 4
Dependent Claim
