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.

Claims

1. A system comprising:

an introducer tip configured to be inserted into a vessel of a patient;

an anvil configured to be inserted into the vessel of a patient, wherein the anvil is proximal to the introducer tip to permit the anvil to be inserted into the vessel after the introducer tip has been inserted into the vessel, wherein the anvil comprises a proximal surface;

a pull tube fixed to the anvil;

a clamp foot;

a clamp tube fixed to the clamp foot, wherein the pull tube and the clamp tube are movable relative to each other to selectively move the anvil and the clamp foot between a closed state in which the anvil and the clamp foot are in close proximity to each other and an open state in which the anvil and the clamp foot are spaced further from each other than when they are in the closed state, and wherein the anvil and the clamp foot are configured to hold a wall of the vessel between them when in the closed state; and

a cutter tube that comprises a cutter at a distal end thereof, wherein the cutter tube is movable relative to the pull tube and the clamp tube and is configured to pass over the clamp foot to bring the cutter into contact with the proximal surface of the anvil to cut the wall of the vessel when the anvil and the clamp foot are holding the wall of the vessel when in the closed state.
