  • Cannula system and method
    Patent number: 8257323
    Abstract: Embodiments of the invention provide a cannula having a body with a first outer diameter, a proximal end, a distal end, a lumen extending between the proximal and distal ends, and a portion outward of the first outer diameter having a second outer diameter greater than the first outer diameter that is adapted to space tissue from the fluid inlet to maintain fluid flow. Such a cannula is particularly useful for cardiopulmonary bypass procedures using a kinetically assisted venous drainage system.

  • Adjustable supporting bracket having plural ball and socket joints
    Patent number: 5899425
    Abstract: An articulating supporting bracket for a surgical tissue stabilizer comprises a series of elements joined to one another by articulating ball-and-socket joints. A flexible cable extends through passages in the elements, and, when tightened, causes the balls and sockets to lock together frictionally. The ball of each joint fits into its socket by an interference fit, whereby the ball and socket of each joint engage one another over an area of contact when the cable is tightened, thereby providing a strong, rigid support for the tissue stabilizer.
