Abstract
A forceps includes a housing having a shaft attached thereto. The shaft has an end effector assembly disposed at a distal end thereof. The end effector assembly includes a pair of jaw members disposed in opposing relation relative to one another. At least one of the jaw members is moveable relative to the other between a spaced apart position and an approximated position for grasping tissue therebetween. At least one shape memory cutting member is coupled to one of the jaw members. The shape memory cutting member(s) is transitionable between a retracted state and an extended state. In the extended state, the cutting member(s) extends between the jaw members to cut tissue disposed therebetween when the jaw members are in the approximated position.
