Abstract
A device having a cutting implement movable in a direction generally parallel to a tissue surface and creating a cut line that does not extend to the proximal end of tissue adjacent the device is disclosed. The device has a cutting implement that emerges from a tissue engaging surface and cuts tissue only between a proximal and distal ends of the adjoining staple lines. A method is further provided for anastomosing two lumens without extending the passageway between them to the openings made for the forks of the anastomosis device.
