Abstract
An end effector assembly adapted to couple to an electrosurgical instrument, the end effector assembly including a plurality of spaced apart small seal plates on opposing jaw members where each seal plate forms a pair of seal plates with the corresponding seal plate on the opposing jaw member. Each pair of seal plates is individually activatable, and the pair of seal plates are activated in sequence. When the opposing jaw members are in an approximated position, the pairs of seal plates around the periphery of each jaw member define a gap therebetween that is larger than the gap between pairs of seal plates along the center of each jaw member.
