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 member fixed to the anvil;
a clamp foot;
a clamp member fixed to the clamp foot, wherein the pull member and the clamp member 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 member that comprises a cutter at a distal end thereof, wherein the cutter member is movable relative to the pull member and the clamp member 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.

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.

14. A system comprising:
-
an anvil configured to be inserted into a vessel of a patient, wherein the anvil comprises a proximal surface; a clamp foot that is selectively movable relative to the anvil, wherein the clamp foot and the anvil are configured to be moved 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; a plurality of teeth that are configured to be inserted into the vessel of a patient, wherein the plurality of teeth comprise proximal ends that are configured to engage the vessel wall when they are moved in a proximal direction after having been inserted into the vessel of a patient; a pull member fixed to the anvil, wherein the plurality of teeth encompass the pull member; and a cutter member that comprises a cutter at a distal end thereof, wherein the cutter member is movable relative to the clamp foot and is configured to contact the proximal surface of the anvil to cut the wall of the vessel when the proximal ends of the teeth are engaging the vessel wall and when the anvil and the clamp foot are holding the wall of the vessel in the closed state. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A system comprising:
-
an anvil configured to be inserted into a vessel of a patient, wherein the anvil comprises a proximal surface; a pull member fixed to the anvil; a clamp foot; a clamp member fixed to the clamp foot, wherein the pull member and the clamp member 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; a cutter member that comprises a cutter at a distal end thereof, wherein the cutter member is movable relative to the pull member and the clamp member 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; and a tract dilator configured to encompass at least the clamp member and the pull member, wherein the tract dilator is configured to move from a constricted state to an expanded state to expand an insertion tract in the skin of a patient. - View Dependent Claims (24, 25, 26, 27, 28)
