Anastomosis clipping tool with half-loop clip
A tool to fasten tissue or to fasten a prosthetic to tissue includes a gripper to hold one or more tissue portions, a needle, an actuator to drive the needle, a fastener cartridge to store one or more tissue fasteners, a holder cartridge to store one or more holders, and a holder applier to secure one of the holders on one of the fasteners. The actuator drives the needle and the needle pulls a first fastener from the fastener cartridge. The actuator drives the needle through the one or more tissue portions held by the gripper to form a hole in the tissue portions. The needle pulls a leading portion of the first fastener through the hole without a trailing portion of the first fastener being pulled through the hole. The holder applier secures a first holder from the holder cartridge onto the leading portion of the first fastener.

a controller to control operation of the tool and the positioning device.
13. A method to fasten tissue using the tool according to claim 1 , comprising:
orienting the tool to a configuration to begin a sequence of fastening the tissue;
gripping a first piece of the tissue to be fastened with the gripper of the tool;
advancing the needle of the tool to pierce the first piece of the tissue to be fastened;
opening the gripper while the needle remains pierced through the first piece of the tissue to be fastened;
gripping a second piece of the tissue to be fastened with the gripper;
further advancing the needle to pierce the second piece of the tissue to be fastened;
