  • Patent number: 7731650
    Abstract: A system and method for capturing and placing a cardiac assist device on a heart. A cardiac assist device is delivered to a chest cavity of a being through an opening provided in a chest wall. A magnetically charged tether is provided at each corner or extremity of the cardiac assist device. Capture instruments magnetically couple with a corresponding tether. The magnetically coupled instruments and tethers then maneuver the cardiac assist device to a desired position about the heart. The cardiac assist device is then secured directly to the heart or to anchoring devices separately provided and secured to the heart.

  • Patent number: 7601117
    Abstract: Systems and methods for reducing distention in designated portions of a heart muscle while assisting cardiac valve alignment and coaptation. Anchoring devices are secured to the heart muscle and a bio-compatible cardiac assist device placed over portions of the heart muscle is separately secured to the anchoring devices. The cardiac assist device may be a material that wraps portions of the heart muscle, or may be straps that wrap portions of the heart muscle. Tightening and securing the cardiac assist device in place helps to reduce distention in chambers of the heart muscle and aids alignment and coaptation of cardiac valves.

  • Patent number: 6837852
    Abstract: A suction device for applying vacuum to a tissue surface is provided. The suction device including: a suction cup portion having a wall defining a cavity and an engagement surface for engaging the tissue surface; a vacuum inlet portion connected to the suction cup portion, the vacuum inlet portion having an inlet for connection to a vacuum source and a conduit in fluid communication with the vacuum inlet and the cavity such that a vacuum applied to the inlet is transferred to the cavity; and a valve disposed in the bore for selectively venting the vacuum in the cavity.

  • Patent number: 6764444
    Abstract: A surgical retractor system including: a surgical retractor for retracting tissue surrounding an opening; and an attachment member having a linear or non-linear edge along a length; and an accessory device for use with the surgical retractor, the accessory device having a channel in sliding engagement with the edge along the length, the channel being the other of linear and non-linear along a width thereof such that the accessory device is movable along the length of the edge into a desired position upon the application of a moving force and locked in the desired position in the absence of the moving force. Also provided are various mounts for disposing the edge in the channel and a pseudoelastic arm for supporting the accessory device from the attachment member, the arm being capable of articulation into a desired position yet also maintaining the desired position during a surgical procedure.

  • Publication number: 20040002631
    Abstract: A suction device for applying vacuum to a tissue surface is provided. The suction device including: a suction cup portion having a wall defining a cavity and an engagement surface for engaging the tissue surface; a vacuum inlet portion connected to the suction cup portion, the vacuum inlet portion having an inlet for connection to a vacuum source and a conduit in fluid communication with the vacuum inlet and the cavity such that a vacuum applied to the inlet is transferred to the cavity; and a valve disposed in the bore for selectively venting the vacuum in the cavity.

  • Publication number: 20040002630
    Abstract: A suction device having a vacuum inlet portion having an inlet for attachment to a vacuum source; and a suction cup portion connected to the vacuum inlet portion, the suction cup portion having a wall defining a cavity in fluid communication with the inlet and an engagement surface for engaging the tissue surface; the suction cup being configured to minimize injury to the tissue surface caused by the applied vacuum. The configuration of the suction cup having at least one of: a plurality of channels formed in the cavity on an inner surface of the wall for allowing the applied vacuum to be distributed over the tissue surface and thereby minimizing injury thereof; an elastic mesh disposed in the cavity such that it engages the tissue surface; and a closed cell foam member disposed on the suction cup portion such that it engages the tissue surface.

  • Publication number: 20040002632
    Abstract: A suction device includes a suction cup having a vacuum inlet for connection to a vacuum source. The suction cup has a wall defining a cavity that is in fluid communication with the vacuum inlet and an engagement surface for engaging a tissue surface. The suction cup is formed of a material that minimizes injury to the tissue surface contacted by the engagement surface and tissue captured when the vacuum is applied and permits the captured tissue to be perfused during use of the suction device.
