  • Patent number: 7569064
    Abstract: A surgical apparatus useful in closing an atrial appendage may include a clamp with a first arm and a second arm spaced apart from one another along at least a portion of their length, pins associated with the first arm, and a locking plate associated with the second arm. The clamp may have an open position in which the arms are spaced apart from one another, and a closed position in which the arms are closer to one another. To close the atrial appendage with the apparatus, the clamp in the open position may be placed relative to the atrial appendage such that it is located between the arms, and the clamp may be moved to the closed position, where that motion may cause the pins to penetrate the atrial appendage and engage the locking plate.

  • Publication number: 20090065552
    Abstract: A surgical endocutter may include an end effector, at least one feeder belt that extends at least partially into the end effector; and two or more staples, where each staple has a first end frangibly connected to a corresponding feeder belt and a second, free end, and where the staples form at least one row. The endocutter may be used to treat a patient by inserting the end effector into the body of a patient through an opening such as a trocar port, engaging tissue with the end effector, stapling tissue along two staple lines with the end effector; cutting tissue between the staple lines with the end effector, releasing the tissue from the end effector, and repeating the holding, stapling and engaging on tissue at a different location within the body of the patient without removing the end effector from within the body of the patient.

  • Patent number: 7291157
    Abstract: A surgical tool for performing anastomosis may include a staple holder; a clip detachably connected to the staple holder; a length of suture, wherein a portion of the length of suture is held securely between the clip and the staple holder; and a needle connected to the suture. An incision may be made at one end of the graft vessel to form a flap. The needle may penetrate the wall of the graft vessel proximal to the incision, and the graft vessel may then be parachuted down the suture toward engagement with the clip. In this way, graft loading onto the clip is facilitated.

  • Patent number: 7285131
    Abstract: An anastomosis system for connecting a graft vessel to a target vessel includes an elongated anvil arm for insertion into the target vessel. The anvil arm includes a contact surface that contacts the inner surface of the wall of the target vessel. The anvil arm includes a channel through which a cutting element translates, and a opening that extends between the channel and the contact surface of the anvil arm. The cutting element is translated along the channel, and is controlled to extend through the opening and make an incision in the wall of the target vessel at a selected location. The incision is made at a location spaced apart from the penetration site at which the anvil arm is inserted into the target vessel, resulting in a tissue bridge between the incision and the penetration site.

  • Publication number: 20070233163
    Abstract: A surgical tool for performing anastomosis between a graft vessel and a target vessel may include an anvil; a cutting element connected to the anvil; and an energy source connected to the cutting element, wherein the energy source is configured to deliver energy to the cutting element. A method for performing anastomosis with that tool may include placing an end of the graft vessel against a side of the target vessel; creating an opening in the wall of the target vessel at a first location; inserting an anvil through the opening from outside the wall of the target vessel into the lumen of the target vessel; creating an incision in the wall of the target vessel spaced apart from the first location; and connecting the graft vessel to the target vessel.
