    Abstract: The invention is surgical instruments which facilitate substantially linear incisions, especially through the wall of vessels, such as arteries, which have been specifically designed for coronary artery bypass graft procedures (CABG) on the beating heart. The instruments of the invention are particularly useful to create the incision in the artery to which the bypass graft is sewed, typically the left anterior descending artery (LAD). The instruments of the invention allow incisions to be rapidly made, precisely measured, and cleanly formed so that a bypass graft can be rapidly sewn in place. In one embodiment, the invention is comprised of a hand-held instrument with a curved cutting edge formed on the interior edge of a curved or arcuitous segment located near the end of the instrument. The tip of the instrument has a point of penetrating the vessel wall. The point may have several alternate shapes to facilitate penetration of the vessel wall while maximizing the trauma to the surrounding tissue. Another embodiment is comprised of a hand-held instrument with moveable member such that the incision is created by engaging a cutting blade against a stop with the tissue being cut therebetween. This instrument is also constructed to facilitate a rapid linear incisions in a vessel while minimizing the possibility for damage to the surrounding tissue. In another embodiment, the instrument features a motion-cancelling member which compensates for the movement of the target surface to be incised. This embodiment has a cutting blade which is manipulated form handle which is isolated from the movement of the tissue containing or proximate to the target of the incision. The instruments facilitate the invasive cardiac procedures by creating linear incisions quickly without undue trauma to surrounding tissue and without excess loss of blood.

    Abstract: The present invention is methods and devices for improving valve function in a heart. Particularly a device of the present invention comprises a an elongate member having a distal end and a proximal end, a thermal heating member fixed to the distal end of the elongate member, wherein the thermal heating member includes at least one thermal heating element adapted to supply thermal energy to a heart valve structure, and an energy source in communication with the thermal heating element. In use, a thermal heating device of the present invention is inserted into working space proximate the valve to be treated and is used to selectively contract the collagen fibers of the valve structure treated so as to improve the performance and functioning of the valve. Devices are disclosed suitable for use with a variety of access procedures on both beating and non-beating hearts, including: a minimally invasive surgical procedure, a sternotomy, a thoracotomy, an endovascular procedure, and endoscopic procedure, or a percutaneous procedure. Methods and devices are disclosed which are suitable for treatment of a chordae, leaflet, or annulus, as well as devices and methods for the replacement of heart valve with prosthetic valves.

    Abstract: A surgical instrument is configured to aid in performing a procedure of detaching an internal mammary artery (IMA) and the like, from the connecting tissues and side branch vessels which surround the artery in its native location, wherein the detaching procedure is preliminary to the performing of a coronary artery bypass grafting procedure and wherein the IMA is detached via a minimally invasive thoracotomy. To this end, an elongated slender rod includes a handle at its proximal end and an artery engaging loop, arc, fork configuration, or hook at its distal working end. Embodiments may incorporate electrosurgical capability or electrical insulation. A surgeon thus has means for harvesting an intact and undamaged graft vessel from its native location through a minimally invasive incision with enhanced speed, visibility, and freedom of motion.
