Claim 11:
12. A forceps end effector comprising:
a shaft;
first and second jaw members connected to the shaft, at least one of the first and second jaw members moveable between a first position wherein the first and second jaw members are spaced apart and a second position wherein the first jaw is moved towards the second jaw member and approaching a transverse plane defined between face portions of the first and second jaw members; and
first and second tissue sealing surfaces each attached to a corresponding one of the first and second jaw members;
wherein the first tissue sealing surface includes at least one cavity formed within a material of the first tissue sealing surface, wherein a compression force of tissue grasped between the first and second jaw members in the second position localizes more at an offset distance spaced apart from a medial plane than at a location along the medial plane, the medial plane defined as:
bisecting each of the shaft, the first jaw member, and the second jaw member; and
being orthogonal to the transverse plane;
wherein the at least one compression feature includes at least one section that is increasingly less rigid at increasing offset distances spaced apart from the medial plane.
