Abstract
Surgical instrumentation and methods for performing a bypass procedure in a digestive system incorporate laparoscopic techniques to minimize surgical trauma to the patient. The instrumentation includes an outer guide member dimensioned for insertion and passage through an esophagus of a patient and defining an opening therein extending at least along a portion of the length of the outer guide member, an elongate anvil delivery member at least partially disposed within the opening of the outer guide member and being adapted for longitudinal movement within the outer guide member between an initial position and an actuated position and an anvil operatively engageable with the delivery member. The anvil includes an anvil rod defining a longitudinal axis and an anvil head connected to the anvil rod. The anvil head is at least partially disposed within the opening of the outer guide member when in the initial position of the delivery member and is fully exposed from the distal end of the outer guide member upon movement of the delivery member to the actuated position.
