  • Patent number: 9498198
    Abstract: Surgical devices for stabilizing the heart are disclosed which facilitate anastomosis under beating heart conditions. Various instruments or devices may be maneuvered and secured on a retractor device to provide stabilization of the heart. An instrument mount is provided which is preferably configured to accept a surgical instrument, such as a tissue stabilizer, and to allow the instrument to be easily maneuvered to a desired position and subsequently locked into position with a simple operation of a single locking actuator. Further disclosed are stabilizer devices each having at least one surface for contacting the heart and each being adapted to be mounted to the retractor while having the ability to be positioned in the desired location against the heart.

  • Publication number: 20090137865
    Abstract: Devices and methods are disclosed for stabilizing tissue within a patient's body during a surgical operation to provide a relatively motionless surgical field. The devices involve tissue stabilizers which provide superior engagement with a tissue structure to be stabilized, for example the beating heart. The tissue stabilizer may have one or more stabilizer feet which provide for adjustment of the orientation of the features which engage the surface of the tissue structure. In one instance, the orientation may be adjusted to ensure the engaging features will be properly aligned with the surface of the tissue structure before engagement. In addition, once engaged with or connected to the tissue structure the orientation may be adjusted to yield an optimum surgical presentation of a portion of the tissue structure, for instance a coronary artery or the like. The tissue stabilizer may be configured to use friction, negative pressure, or both to engage the surface of the heart.

  • Patent number: 6758808
    Abstract: Stabilization devices, systems and methods for stabilizing tissue to perform a surgical operation while the heart of the patient continues to beat. A stabilization system including a tissue contact member having a surface adapted to contact the tissue and temporarily maintain the tissue in a relatively immobilized state; and a maneuverable arm attached to the tissue contact member, which includes at least one articulating joint formed by a link having a male articulating surface composed of angled teeth and a female articulating surface having angled trenches adapted to receive the angled teeth.

  • Patent number: 6656113
    Abstract: In accordance with the present invention, there is disclosed surgical methods and apparatus for accessing and stabilizing the heart. The methods and apparatus facilitate access to an anastomosis site, allows various instruments or devices to be maneuvered and secured in place, and provide stabilization of the heart. The apparatus may involve a tissue stabilizer, and in particular a tissue stabilizer for use in immobilizing or stabilizing a portion of the beating heart using a compressive force delivered to the heart via the tissue stabilizer. The stabilizer may include a stabilizer base and a shaft. The shaft may be secured within an appropriate instrument mount preferably fixed to a retractor or other stable platform as disclosed herein. The stabilizers of the present invention provide improved access to a surgical site at a target vessel on the surface of the heart and may include features which facilitate optimal presentation of the target vessel.
