This application is directed to a surgical stapling device for performing circular anastomoses. The stapling device includes a retractable trocar which is slidably supported by an anvil retainer and movable from a retracted position located within the anvil retainer to an advanced position extending from the anvil retainer. The trocar defines a sensor and is operatively connected to an indicator assembly. The indicator assembly is operatively associated with an anvil assembly such that the indicator will not move from a fire-not ready position to a fire-ready position until an anvil assembly has been mounted to the anvil retainer.

Surgical method and apparatus for resectioning tissue, preferably lumenal tissue, with a remaining portion of an organ being anastomized with staples or other fastening devices, preferably endolumenally. The apparatus may be inserted via a naturally occurring body orifice or a surgical incision and then advanced using either endoscopic or radiological imaging guidance to an area where surgery is to be performed. Under endoscopic or diagnostic imaging guidance the apparatus is positioned so tissue to be resected is manipulated into an inner cavity of the apparatus. The apparatus then cuts the diseased tissue after stapling and retains the diseased tissue within the apparatus. The rent resulting in a border of healthy tissue is anastomosed with surgical staples.
