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. The actuator is proximal to the ball and socket, and preferably is adjacent the distal end of the tube.
