Abstract: A method of surgical dissection of tissue with a dissector comprising: an elongate shaft comprising a proximal portion and a distal portion, wherein the distal portion comprises a plurality of segments that articulate with respect to one another and the plurality of segments includes a distal segment having a distal end; and a handle attached to the proximal portion of the shaft, wherein the handle comprises controls for articulating the plurality of segments of the distal portion of the shaft with respect to one another, comprising the steps of: positioning the distal end of the dissector in a body; advancing the distal end through the body to dissect tissue; and simultaneously articulating the plurality of segments with respect to one another. A method of surgical dissection of tissue and guiding a second device to a desired physiological location with a first device.

Abstract: An ablation catheter assembly including an elongate catheter body having a proximal portion, a distal portion and a lumen therethrough. A helical structure associated with the catheter distal portion carries a plurality of independently operable electrodes and is transformable between a low-profile configuration wherein a straightening element is positioned in the lumen and an expanded configuration wherein the straightening element is at least partially retracted from the spiral structure. When the helical structure is in the expanded configuration, a laterally offset tip portion extends distally therefrom.

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.
