Abstract
An apparatus for ablating tissue within a treatment region includes an ultrasound treatment transducer (36, 36′) for orienting at a first longitudinal orientation and a first angular orientation (40, 42) within the treatment region (26), for orienting at the first longitudinal orientation and a second angular orientation (40, 42) within the treatment region, and for orienting at a second longitudinal orientation and the first angular orientation (40, 42) within the treatment region, and a drive system for exciting (via conductors 46) the transducer (36, 36′) to ablate tissue (60) oriented adjacent the first longitudinal orientation and the first angular orientation within the treatment region (26), adjacent the first longitudinal orientation and the second angular orientation within the treatment region (26), and adjacent the second longitudinal orientation and the first angular orientation within the treatment region (26), respectively.
