Abstract
A surgical fastener for use with an anastomosis of two tissues includes a base leg and an upright leg. The base leg is selectively deformable and includes a traumatic tip for piecing tissue. The surgical fastener also includes at least one capillary disposed on the base leg which has a reservoir defined therein for retaining a liquid, e.g., bioadhesive, bonding agent, medicament, etc. Each of the capillaries is ruptureable upon deformation of the surgical fastener to dispense the liquid to the anastomosis site.
