    摘要： A device for holding a surgical suture including a base, a guide body, a cam body, a bearing member, and a spring member. The base has a top side, a front edge, and a back edge. The guide body projects from the top side of the base and defines a guide face having an entrance side and an exit side. The entrance side is adjacent the front edge and the exit side is adjacent the back edge. The cam body is pivotally mounted to the top side and forms a toothed surface positioned to selectively secure a surgical suture against the guide face. The spring member is positioned between the cam body and the bearing member, biasing the toothed surface toward the guide face.

    摘要： System, device and method for ablating target tissue adjacent pulmonary veins of a patient through an incision. An ablation device can include a hinge including a cam assembly, a moving arm, a floating jaw, and a lower jaw. Fingers can engage the floating jaw to hold the floating jaw in a first position with respect to the moving arm. Some embodiments of the invention can provide an ablation device including a central support, an upper four-bar linkage coupled to the central support, an upper jaw coupled to the upper linkage, a lower four-bar linkage coupled to the central support, and a lower jaw coupled to the lower linkage. Some embodiments of the invention can provide an ablation device having an upper jaw including a first cannula connection and a lower jaw including a second cannula connection. The system can include a first catheter coupled to the first cannula connection and a second catheter coupled to the second cannula connection. The first and second catheters can be inserted through the incision and can move the upper and lower jaws adjacent the pulmonary veins.

    摘要： Methods and apparatus employed in surgery involving making precise incisions through body vessel walls, particularly coronary arteries. A body vessel cutting instrument comprises an elongated instrument shaft extending between a shaft proximal end adapted to be manipulated outside the patient's body and a shaft distal end and having a shaft axis and first and second cutting blades supported at the shaft distal end. The first cutting blade extends substantially orthogonally or laterally to the shaft axis and has a first cutting edge extending along a trailing side, a cutting tip at the first cutting blade free end, and an atraumatic blunt surface along the leading side. The second cutting blade has a second cutting edge extending along a leading side, whereby the first and second cutting edges face one another and are brought together to slit a vessel wall.
