The jaw members are each longitudinally curved with respect to the longitudinal axis. The dynamic clamping member is disposed in mechanical cooperation with a distal portion of the drive assembly and includes an upper beam, a lower beam, and a vertical beam having a cutting edge on a distal portion thereof. At least a portion of the dynamic clamping member is longitudinally curved with respect to the longitudinal axis. The tissue stop is disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members.
