ABSTRACT:
A heart stabilizer and suture control device for stabilizing the heart and for occluding a preselected portion of coronary artery by developing a downward force on the heart and simultaneously developing an upward force across a coronary artery in a predetermined position. The device has at least two stabilization pads, the stabilization pads each having an operative size and shape, and each having a first end and a second end and a lower contacting surface. The second ends have suture retaining grooves, and the stabilization pad has a suture locking means for securing the distal end of a suture means thereto. The device also comprises a linking member locking the two stabilization pads an operative distance apart. The device has suture means with a proximal end coupled to the linking member and extending from the first end to the suture retaining groove of the second end, the suture means having a distal end which can be locked to the stabilization pad with the suture locking means thereon. The device also has means for rotating the linking member such that when operatively positioned adjacent a coronary artery to be occluded with the suture threaded between the coronary artery and the remaining portion of the heart muscle, rotating the linking member will cause the proximal end of the suture means to be wound onto the linking member and thus tighten the suture between the first end and the second end of each stabilization pad and urge the coronary artery against the contacting surface, thereby causing occlusion of the coronary artery as desired.
