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.

Abstract: An apparatus for performing transmyocardial revascularization provides a closed-chest formation of a channel in a wall of a heart. An articulating scope in one embodiment includes a flexible distal portion which provides for a coupling of a surface of the heart to the distal portion. The articulating distal portion is coupled to a control member to provide articulation. Movement of the control member causes deflection, including articulation, of the generally flexible working end of the scope. The coupler may be a two way valve to provide both vacuum and flushing solutions. The articulating scope can be supported by a scope holder that is table mounted or mounted to the patient. An access port provides for the introduction of tools and instruments. An adaptor couples the access port with a handle. The handle provides a working channel for the introduction of an energy delivery device.

Abstract: A tissue-ablation method and apparatus are disclosed. The apparatus includes a plurality of RF ablation electrodes, and a plurality of sensor elements, each movable from retracted to deployed positions in a tissue to be ablated. A control device in the apparatus is operatively connected to the electrodes for supplying an RF power to the electrodes, to produce tissue ablation that advances from individual-electrode ablation regions to fill a combined-electrode ablation volume. The control device is operatively connected to the sensor elements for determining the extent of ablation in the regions of the sensor elements. The supply of RF power to the electrodes can thus be regulated to control the level and extent of tissue ablation throughout the combined-electrode volume. The electrodes are preferably hollow-needle electrodes through which liquid can be infused into the tissue, also under the control of the control unit, to modulate and optimize tissue ablation.
