1. A forceps for sealing tissue, comprising:
- a housing having at least one shaft that extends therefrom for supporting an end effector assembly at a distal end thereof, the end effector assembly including a pair of opposing jaw members each including a sealing plate, the sealing plates configured to grasp tissue and a foreign material therebetween, at least one of the sealing plates adapted to connect to an electrosurgical energy source for applying electrosurgical energy to tissue and the foreign material to form a tissue seal, at least one of the sealing plates including a predetermined surface geometry defined thereon that is non-complementary relative to the other sealing plate such that a corresponding surface geometry is imprinted onto the tissue seal to facilitate sealing tissue with the foreign material when electrosurgical energy is applied to the at least one sealing plate.

Abstract
A forceps for sealing tissue includes a housing having one or more shafts that extend therefrom configured to support an end effector assembly at a distal end thereof. The end effector assembly includes a pair of opposing jaw members each having a sealing plate with tissue engaging surfaces adapted to connect to an electrosurgical energy source. At least one of the sealing plates includes a predetermined surface geometry defined thereon that imprints a corresponding surface geometry onto the tissue seal to facilitate sealing the tissue with a foreign material when electrosurgical energy is applied to the forceps.
