摘要： Various devices for ablating tissue in a lateral direction and methods of operation thereof. One embodiment of such a device includes: (1) an elongated body configured to carry ablative energy from an ablative energy source associated with a proximal end to a distal end and (2) a distal tip located at the distal end, the distal tip configured to deliver the ablative energy in a direction substantially lateral to a longitudinal axis of the elongated body.
