Temperature-controlled fiber optic laser soldering system has proved to be effective for surgical laser bonding of the edges of human tissue. Laser heating methods are less traumatic to tissue because they cause fewer foreign body reactions, and potentially they lead to faster wound healing and result in much less scanning. Thermal damage depends exponentially on temperature and linearly on time, and researchers has assumed that the accurate monitoring and control of the temperature of the site of the bonded tissue are essential to reduce thermal damage and increase the immediate bond strength. CO2 laser heating with albumin solder has been used for in vivo experiments involving laser bonding of cuts in the urinary bladders of rabbits, and the experiment produced a tensile strength and showed no complications.
