End-to-end anastomosis instrument and method for performing same
First Claim
1. A loading unit for use with a surgical instrument for performing an end-to-end anastomosis of first and second luminal structures, the loading unit comprising:
- a first retracting sleeve including a base and a sleeve cap, the first retracting sleeve being configured to support a plurality of fasteners on a distal end thereof;
a second retracting sleeve disposed about the first retracting sleeve, the second retracting sleeve including upper and lower cuffs; and
a fastener support configured to house the first and second retracting sleeves, the fastener support including upper and lower supports; and
wherein the sleeve cap of the first retracting sleeve, the lower cuff of the second retracting sleeve and the lower support of the fastener support are pivotally connected with respect to the base of the first retracting sleeve, the upper cuff of the second retracting sleeve and the upper support of the fastener support to permit removal of a first luminal structure therefrom after the first luminal structure is secured to a second luminal structure.

Abstract
A surgical instrument for performing an end-to-end anastomosis of first and second luminal structures includes a housing having an actuator attached thereto and a selectively removable loading unit attached to a distal end of the housing which supports any array of surgical fasteners at a distal end thereof. The surgical fasteners are simultaneously deformable upon activation of the actuator such that a distal end of each surgical fastener secures each end of each luminal structure to complete the end-to-end anastomosis wherein the resulting eversion is exterior to the luminal structures.
