Abstract

Laser repair of liver using albumin is a promising method for treating liver trauma. Concentrated human serum albumin is applied to a liver laceration and then denatured using a laser. These repairs were pulled with a material tester to measure the ultimate strength of the laser repair. We show that the ultimate strength of the liver repairs tends to increase with delivered laser energy, that the mode of delivery (pulsed versus continuous) does not matter, that the repair strength correlates with the area of denatured albumin, and that strong welds cause about 1.5 mm of thermal damage.
