Vascular Tissue Bonding Using Laser Energy

Low-power laser energy is being evaluated extensively as a method of fusing soft tissues and replacing or augmenting standard suture techniques [1–8]. This method is appealing because 1) it produces improved healing without the foreign-body reaction associated with sutures [1–7, 9–13], 2) it has the potential for reducing the technical difficulty of microrepairs, and 3) it produces cosmetic closure of skin incisions [2, 14]. Laser vascular tissue fusion shows promise in improving healing at the sites of anastomoses by reducing or eliminating intimal hyperplasia [9], by possibly preserving mechanical properties such as compliance, and by permitting normal growth of vessels [10].
