Abstract

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.
