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.
