  • Patent number: 6015416
    Abstract: In accordance with the present invention, there is provided a surgical device for attaching a first hollow organ to a second hollow organ and creating a passageway therebetween. The device includes a first member comprising a first prong for entering a wall of the first hollow organ and a second prong for entering a wall of the second hollow organ. The prongs each have a proximal end which attaches to the first member and a distal end extending therefrom. The device further includes a second member having a plow for incising at least one of the hollow organs so as to create a passageway between the hollow organs. The second member further includes a plurality of needle paths on either side of the plow for guiding a needle through the walls of the hollow organ on either side of the passageway. The device further includes a means for driving a needle, having a suture attached thereto, so as to attach the hollow organs together.

  • Patent number: 6013027
    Abstract: A method is described for stabilizing moving tissue within the body. The method comprises creating a first opening for primary surgical access into the body, and a second opening spaced apart from the first opening in the body. An elongated stem having a proximal end and a distal end is inserted into the second opening. A foot having an upper and a lower surface is inserted into the first opening. The lower surface of the foot is engaged with the moving tissue within the body. The distal end of the stem is releaseably attached to the foot. The proximal end of the stem may be held so as to stabilize the moving tissue within the body.

  • Patent number: 6007486
    Abstract: In accordance with the present invention there is provided a device for stabilizing moving tissue, such as a beating heart, so as to facilitate surgical procedures on such tissue. The device includes a tube having a proximal end, a distal end and a lumen extending therebetween. The tube has a flexible hose extending through the lumen of the tube between its distal and proximal ends. The hose having a proximal end connected to a suction source so as to draw air through the tube from its distal end to its proximal end. The tube is made up of a plurality of segments which are detachable from one another. The device further includes at least one foot connected to the distal end of the tube. The foot extends laterally from the tube. In a preferred embodiment the device includes a pair of feet which are spaced apart laterally from each other. Each foot has a proximal surface, and a distal surface for making contact with the tissue.

  • Patent number: 5879291
    Abstract: In accordance with the present invention, there is provided a device for pivoting a surgical retractor with respect to a patient it is being used on. The device includes a bridge having distal and proximal ends wherein a distal coupling is attached to the distal end of the bridge and a proximal coupling is slidably attached to the bridge proximal to the distal coupling. The proximal and distal couplings include a means for releasably attaching itself to a surgical retractor. The device further includes a lifting assembly attached to the bridge proximal to the proximal coupling. The lifting assembly comprises a means for applying an upward force to the proximal coupling, whereby when the device is attached to a surgical retractor, the lifting assembly pivots the retractor upward about the distal coupling.

  • Patent number: 5865730
    Abstract: In accordance with the present invention there is provided a device for stabilizing and/or manipulating moving tissue, such as a beating heart, so as to facilitate surgical procedures on such tissues. The device includes a tube having a proximal end, a distal end and a lumen extending therebetween. The tube is operatively connected to a suction source so as to draw air through the tube from the distal end to the proximal end. The device further includes at least one foot operatively connected to the distal end of the tube. The foot extends laterally from the tube. In a preferred embodiment the device includes a pair of feet which are spaced apart laterally from each other. Each foot has a proximal surface, and a distal surface for making contact with the tissue. Each foot is attached to the tube by a ball and socket connector. The ball and socket connector is operatively connected to an actuator which can release and re-engage the ball from the socket.

  • Patent number: 5846194
    Abstract: In accordance with the present invention, there is provided an apparatus for pivoting a surgical retractor with respect to a patient it is being used on. The apparatus has a bridge for engaging at least one arm of a surgical retractor. The bridge has a distal end, a proximal end and a longitudinal axis extending therebetween. The bridge further includes a distal coupling attached to the distal end of the bridge for releasably attaching the bridge to the surgical retractor. The apparatus also has a lifting assembly comprising an elevator. The lifting assembly is for applying an upward force to the proximal end of the bridge, so that when the apparatus is attached to a surgical retractor the lifting assembly pivots the retractor upward about the distal coupling. The elevator includes a bridge coupling for attaching the lifting assembly to the proximal end of the bridge. The bridge coupling has a rotatable connection for allowing the bridge to rotate about its longitudinal axis.
