The epicardial clip includes a curved member having an anterior segment configured to be positioned in the transverse sinus of the heart, a posterior segment configured to be positioned on the posterior side of the heart, such as on or inferior to the atrioventricular groove, and a lateral segment extending between the anterior segment and the posterior segment. The lateral segment includes a curve such that the first end of the member is positioned at or above the plane of the mitral valve and the second end of the member is positioned at or below the plane of the mitral valve.

Organ manipulation devices for atraumatically grasping the surface of an organ and repositioning the organ to allow access to a location on the organ that would otherwise be substantially inaccessible. Methods of accessing a beating heart, retracting the heart using an organ manipulation apparatus, and stabilizing a surgical target area with a stabilizer. Both the organ manipulator and stabilizer are fixed to a stationary object which may be a sternal retractor. A system for performing beating heart coronary artery bypass grafting includes a sternal retractor, organ manipulator and stabilizer.
Endoscopic surgical instruments, lens elements and methods of treating or ablating tissue such as epicardial surfaces of cardiac tissue. An endoscopic surgical instrument includes an elongate shaft, a lens attached to the distal end of the shaft, and a coupling element extending from or attached to the lens. The distal end of the lens can protrude through the coupling element so that an ablation element, such as a flexible microwave ablation element, held by the coupling element is in the line of sight of the lens. Embodiments can be used to selectively ablate epicardial surfaces to treat atrial fibrillation and form more complete lesions around pulmonary veins without severing or penetrating a pericardial reflection near the superior vena cava.

Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end. The tool for manipulating vessels may have a low-profile for increased visibility of operation, and may be coupled to the cannula with a damping mechanism to reduce the possibility of avulsion of the vessels. Various vessel cutting and sealing devices are provided that may accommodate various sizes of vessels and improve cutting and sealing efficacy.
