    摘要： The invention provides a percutaneous visualization system for direct, stereoscopic visualization of a body cavity during minimally-invasive surgical procedures. The visualization system includes a cannula having a distal end, a proximal end, and a passage extending therebetween. The passage is configured to allow stereoscopic vision therethrough, and is preferably tapered from the proximal end to the distal end. A sleeve is positionable in the passage of the cannula, the sleeve having an optical passage also configured to allow stereoscopic vision, preferably by tapering. A lens may be disposed in the optical passage of the sleeve tier wide-angle viewing. Magnification means may be positioned in optical alignment with the optical passage to provide a magnified image of a surgical site.

    摘要： The invention is devices and techniques which use a negative (suction) pressure or vacuum, applied through a surgical instrument, to fix the position of a portion of the surface of a beating heart so that a surgical procedure can be more easily performed. The devices apply a negative pressure at several points on the outer surface of the heart such that a portion of the heart is fixed in place by the suction imposed through the surgical instrument. Because the instrument fixes the position of the tissue, and because the instruments remain at a constant distance from the particular portion of the heart where the surgery is being performed, the device may also serve as a support or platform so that other surgical instruments or devices can be advantageously used at the site. In certain preferred embodiments, the devices described herein have structures to facilitate the use of additional surgical instruments such that the placement of negative pressure device permit the surgeon to advantageously manipulate the other instruments during surgery. The negative pressure is preferably imposed through a plurality of ports which may be disposed in a substantially planar surface of the instrument which contacts the cardiac tissue.

    摘要： An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, so increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.

    摘要： A method and apparatus for facilitating coronary surgery on the beating heart wherein the vagus nerve is electrically stimulated to purposely temporarily stop or substantially reduce the beating of the heart under precisely controlled conditions. The apparatus controllably applies the electrical stimulus to preselected locations along the vagus nerve and thus to preselected nerve branches related to the heart. The apparatus includes several clip and probe configurations for establishing electrical contact with the vagus nerve. Such purposely caused temporary stoppage or substantial reduction of the beating of the heart facilitates procedures such as suturing of an anastomosis which would otherwise be more difficult because of the motion induced by the beating heart.
