  • 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: 20120078061
    Abstract: Devices and methods are disclosed for accessing and stabilizing an unstable or moving tissue structure within a patient's body, and in particular, for temporarily stabilizing a target site on the beating heart. The devices generally involve tissue stabilizers having at least one multiple link support member operably connecting a stabilizer foot to a retractor. The tissue stabilizer may have a stabilizer foot allowing for additional members to be connected to the stabilizer foot at discreet locations. The support member and the additional members may be attachable to a retractor. The support member and the additional members may be operably associated with attachments or mounts which provide additional degrees of freedom at a connection to the retractor.

  • 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: 7326177
    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, such as during a coronary artery bypass graft procedure. The devices include tissue stabilizers which engage and provide stabilization to a targeted area of tissue and further have the ability to engage and manipulate some portion of tissue within or adjacent the targeted area to improve the surgical presentation of that portion of tissue. The tissue stabilizer typically has one or more stabilizer feet which have a first foot portion configured to provide stabilization to the targeted tissue and a second foot portion moveable relative to the first foot portion for manipulating a portion of tissue to improve the surgical presentation.

  • Patent number: 7238155
    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. In particular, the apparatus involves a retractor assembly having a pair of opposing blades having a channel adapted to engage an incision in a patient. The retractor blades may have features to cooperatively engage an instrument mount. The instrument mount may hold an instrument, such as a tissue stabilizer, and allows the instrument to be easily maneuvered. The retractor blades may have a number of suture locks for securing sutures used during surgery. The retractor system is particularly useful in accessing, positioning and stabilizing the beating heart for coronary artery bypass graft surgery.

  • 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.
