1. A surgical fastener for use with an anastomosis of two tissues, comprising:
- a base leg and an upright leg, said base leg being selectively deformable and including at least one traumatic tip for piercing tissue; and
at least one capillary disposed on said base leg having a reservoir defined therein for retaining a liquid, each of said at least one capillary being rupturable upon deformation of said surgical fastener to dispense said liquid simultaneously with being ruptured.

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.

11. A surgical fastener for use with a surgical instrument for performing an anastomosis between two tissues wherein the surgical instrument includes a selectively engageable loading unit for supporting an array of surgical fasteners and an actuator for initiating deformation of the surgical fasteners, each of the surgical fasteners comprising:
-
a base leg and an upright leg, said base leg being selectively deformable and including a tip for piecing tissue; and at least one capillary disposed on said base leg having a reservoir defined therein for retaining a liquid, each of said at least one capillary being rupturable to dispense said liquid simultaneously upon actuation of the surgical instrument and deformation of each surgical fastener. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
