Abstract
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.
