  • Method and apparatus for temporarily immobilizing a local area of tissue
    Patent number: 7445594
    Abstract: A method and apparatus for temporarily immobilizing a local area of tissue. In particular, the present invention provides a method and apparatus for temporarily immobilizing a local area of tissue within a patient's body cavity. In one embodiment, the tissue immobilized is heart tissue to thereby permit surgery on a coronary vessel in that area without significant deterioration of the pumping function of the beating heart. The local area of heart tissue is immobilized to a degree sufficient to permit minimally invasive or micro-surgery on that area of the heart. The apparatus for temporarily immobilizing a local area of tissue includes a first tissue engaging member and a second tissue engaging member coupled to a spreader. The spreader is operated by an actuator to selectively control the movement of the first tissue engager and the second tissue engager.

  • Method and device for transventricular mechanical circulatory support
    Patent number: 6790171
    Abstract: Invention relates to a cannula and a screw pump for use in a mechanical circulatory support device, in particular a transventricular circulatory support device. The cannula according to the present invention comprises a tubular member made of a flexible, collapsible material having a diameter between 0.5 cm and 3 cm, preferably between 1 cm and 2.5 cm. The invention also relates to an inflatable screw pump for use in circulatory support system which comprises a flexible central drive shaft and an inflatable body having a free edge defining a spiral shaped contour around the central drive shaft and an inner edge connected to the drive shaft. The Archimedes type screw pump may be used in conjunction with the flexible cannula.
