    摘要: 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.

    摘要: A surgical stapler for securing a prosthetic heart valve within a patient is disclosed and generally includes a first cylindrical portion for carrying a staple assembly on a distal end thereof, a second cylindrical portion positioned concentrically about the first cylindrical portion and having a camming arm on a distal end thereof and a third cylindrical portion positioned concentrically about the second cylindrical portion and having an anvil flange on a distal end thereof, the camming arm configured to cam the staple assembly radially outward and drive the staple assembly distally such that a first leg of the staple assembly penetrates a cuff of the prosthetic heart valve and a second leg of the staple assembly pierces a portion of heart tissue surrounding the prosthetic heart valve to secure the valve. A method of installing a heart valve within a patient utilizing the surgical stapler is also disclosed.

    摘要: A surgical stapler for securing a prosthetic heart valve within a patient generally includes a first cylindrical portion for carrying at least one staple assembly on a distal end thereof; a second cylindrical portion positioned concentrically about the first cylindrical portion and having a camming arm on a distal end thereof, the camming arm configured to cam the at least one staple assembly radially outward and drive the at least one staple assembly distally such that a first leg of the at least one staple assembly penetrates a cuff of the prosthetic heart valve and a second leg of the at least one staple assembly pierces a portion of heart tissue surrounding the prosthetic heart valve, as the second cylindrical portion is moved distally relative to the first cylindrical portion; and a third cylindrical portion positioned concentrically about the second cylindrical portion and having an anvil flange on a distal end thereof, the anvil flange configured to crimp the second leg of the at least one staple assembly toward the first leg of the at least one staple assembly to secure the prosthetic heart valve to the surrounding heart tissue as the third cylindrical portion is moved relative to the second cylindrical portion. A method of installing a heart valve within a patient which includes the steps of accessing a site within a heart from which a natural heart valve has been removed; lowering a prosthetic heart valve into position within the site in the heart; positioning a surgical stapler having at least one staple assembly removably held on a distal end thereof adjacent the prosthetic heart valve within the site in the heart; driving a first leg of the at least one staple assembly through a peripheral cuff of the prosthetic heart valve; and crimping a second leg of the at least one staple assembly in a direction toward the first leg such that the second leg pierces a portion of heart tissue surrounding the prosthetic heart valve, thereby securing the prosthetic heart valve to the surrounding heart tissue.

    摘要: An improved surgical dilator extractor is introduced into the abdominal cavity through a trocar cannula and expanded, forming a tissue receiving space, at the distal end. The tissue receiving space is enlarged by passing a grasper through a lumen of the dilator extractor to interact with a guide surface on the interior of dilator extractor to expand a dilator portion having a single leaf beyond the natural resiliency of the leaf. The tissue being extracted is then manipulated into the space with the grasper. The tissue is then removed from the cavity by the surgeon applying a force onto the dilator extractor that insures the elongation of the tissue and temporarily dilates the entry wound to the extent necessary for the tissue to be removed. Alternative embodiments of the surgical dilator extractor and related instrument tool sets and methods for the use thereof also are disclosed.
