    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： Device and method for sub-xiphoid ablation of patient tissue. A sub-xiphoid access clamp has a handle, an elongate neck coupled to the handle and first and second opposing jaws. The first and second opposing jaws have first and second opposing relief segments being generally co-planar and concave with respect to one another to form a void therebetween, and first and second opposing elongate ablation elements positioned along the first and second opposing jaws and distal of the first and second opposing relief segments relative to the handle. The first and second opposing jaws are articulate between a closed position and an open position to admit, at least in part, a second portion of tissue of the patient within the void created by the first and second opposing relief segments while the first portion of tissue is positioned between the first and second ablation elements in the closed position.

    摘要： Structure and method for using a sub-xiphoid ablation clamp for ablating tissue of a patient. The clamp has an elongate shaft having a major axis, first and second opposing jaws configured to open and close along a first plane, a first and second ablation element positioned along the first and second jaws configured to ablate the tissue positioned therebetween, an actuable joint operatively coupled between the shaft and the opposing jaws and configured to move the opposing jaws to a selectable angle relative to the major axis of the elongate shaft along a second plane orthogonal to the first plane. The ablation clamp has a handle operatively coupled to the shaft having an actuator configured to actuate the actuable joint and a trigger mechanism to open and close the opposing jaws.

    摘要： Method and apparatus for ablating target tissue adjacent pulmonary veins of a patient. The ablation device can include a lower jaw assembly including a proximal jaw having a proximal electrode and a distal jaw having a distal electrode, and an upper jaw assembly including an upper jaw having an upper electrode. A proximal actuator can be movable between a first position in which the proximal jaw is open and a second position in which the proximal jaw is clamped with respect to the upper jaw. A distal actuator can be movable between a third position in which the distal jaw is open and a fourth position in which the distal jaw is clamped with respect to the upper jaw.
