Device and method for stabilizing cardiac tissue
First Claim
1. A surgical device for stabilizing cardiac tissue during surgery, said device comprising:
- a support structure having a distal end and a proximal end; and
a stabilizing foot attached to said support structure at a distal end, the foot comprising two laterally spaced apart fingers connected by a bridge at one end of the fingers, said fingers each having an inner edge with said edges being located generally in a first plane and defining a surgical site therebetween, said fingers having bottom surfaces, each said bottom surface having a beveled surface portion extending upwardly and away from the inner edge at an angle in the range of between about 10° and
about 35°
from the first plane.

Abstract
The present invention is directed to a new and useful device and method for stabilizing cardiac tissue at a surgical site during heart surgery, and specifically useful during beating heart surgery. The device includes a foot for contacting a heart tissue and two arms movably connected together for selective movement to vary and adjust the position of the foot on the heart. The foot and the arm assembly are designed to optimize stability of the foot in contact with heart tissue, and therefore, to optimize stability of the heart during surgical procedure. The device is capable of being mounted on a chest spreader. The foot has a bottom surface which is angled for better stabilization and engagement with the heart.

52. The method for selectively isolating and stabilizing cardiac tissue at a surgical site comprising the steps of:
-
obtaining a device for isolating and stabilizing cardiac tissue comprising a stabilizing foot having at least two heart engaging bottom surfaces, such bottom surfaces being inwardly angled relative to each other;
placing said angled heart engaging bottom surfaces on opposite sides of the surgical site;
applying force to the heart through said angled heart engaging bottom surfaces to thereby stretch and stabilize cardiac tissue at the surgical site;
performing a medical procedure on the cardiac tissue. - View Dependent Claims (53, 54, 55, 56, 57)
