Abstract
Tissue management methods can include inserting a clamping device into a vessel and clamping a vessel wall via the clamping device. Tissue can be dilated about the clamping device and an anastomotic device provided to the vessel.
Claims13
A method of managing tissue for creation of an anastomosis, the method comprising:
- inserting an anvil and a clamp foot through a wall of the vessel while the anvil and the clamp foot are in an approximated state, wherein a clamp assembly comprises the anvil and the clamp, and wherein the clamp foot defines a diameter;
- separating the anvil and the clamp foot to an open state after the anvil and the clamp foot have been inserted through the wall of the vessel to create or expand a gap between the anvil and the clamp foot, wherein the anvil and the clamp foot are closer to each other when in the approximated state than they are when in the open state, and wherein a diameter of the clamp assembly within the gap is smaller than the diameter of the clamp foot;
- removing the clamp foot from the vessel after the anvil and the clamp foot have been moved from the approximated state to the open state;
- permitting the vessel wall to resiliently close around at least a portion of the clamp assembly that is within the gap upon removal of the clamp foot from the vessel;
- and
- approximating the anvil and the clamp foot to each other after the vessel wall has resiliently closed around the at least a portion of the clamp assembly to hold the vessel wall between the anvil and the clamp foot.

A method of managing tissue for creation of an anastomosis, the method comprising:
- inserting through a wall of a vessel an anvil and a clamp foot of an assembly that comprises the anvil, the clamp foot, and one or more teeth;
- separating the anvil and the clamp foot from each other after insertion of the anvil and the clamp foot through the wall of the vessel to create or expand a gap between the anvil and the clamp foot;
- providing access to the one or more teeth;
- moving the clamp assembly proximally to capture the wall of the vessel via the one or more teeth after separation of the anvil and the clamp foot from each other and after access to the one or more teeth has been provided;
- and
- approximating the anvil and the clamp foot to each other to clamp the vessel wall between the anvil and the clamp foot after capture of the wall of the vessel via the one or more teeth.
