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 for 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： 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.

摘要： Devices and methods for minimally invasive harvesting of a vessel, especially the internal mammary artery for coronary artery bypass grafting, are disclosed. Generally, an electrosurgical instrument is provided which has a scissors mechanism or other end effector for dissecting tissue. The instrument also has monopolar or bipolar capabilities. Bipolar blade configurations provide current flow between blades or within each blade of the scissors mechanism or both. The instrument includes at least one ergonomically positioned actuator for actuating movement of the blades or end effectors for cutting tissue, for actuating current flow for cauterizing tissue, or for simultaneously or sequentially actuating movement and current flow. In one embodiment, the actuator is operable by a fingertip. The instrument also has a shaft which extends between the scissor mechanism and a handle portion which may be selectively rotatable or malleable to optimize orientation of the scissor mechanism.

摘要： A plurality of embodiments of a distal perfusion device are disclosed, which device facilitates anastomosis constructions by maintaining a dry anastomosis site while simultaneously maintaining blood flow distally in the blood vessel to prevent ischemia and reduce overall patient trauma. The perfusion device is configured for installation into a blood vessel such as a left anterior descending coronary artery through an incision therein, to which is to be grafted a distal end of a blood vessel such as an internal mammary artery. The device includes a central member of selected configuration and material, terminating at either end thereof in respective selectively tapered end members. A lumen extending through the central member and end members, and selected perforations in the end members, maintain blood flow through the perfusion device. A selected portion or portions of the device's outer circumference fit snugly within the artery in the regions beyond and/or at the anastomosis site, to maintain the latter free of blood. Several methods for deploying and removing respective embodiments of the device also are illustrated.

摘要： A method and system for making a three dimensional product wherein the size and shape of a plurality of cross-sectional segments of the three dimensional object are determined which when assembled together in a particular sequence form the desired three dimensional shape. Thin layers of material in the shape of each of the cross-sectional segments are applied in the particular sequence in which they form the three dimensional object. The application of each of the layers is much like a lithographic printing process in that a resin may be applied by a roller in the shape of the cross-sectional segments.
