Claim:
1. A method of ablating tissue with a catheter device system, the catheter device system comprising an energy source device system and a catheter device, the catheter device including a plurality of transducers, the plurality of transducers arranged in a distribution, the distribution positionable in a bodily cavity, the bodily cavity defined by at least one tissue wall, and the energy source device system connected to at least some of the plurality of transducers, the method comprising: activating each group of a plurality of groups of adjacent transducers in the distribution to cause energy from the energy source device system to be delivered to each of the transducers in each group of the plurality of groups of adjacent transducers in the distribution to form a series of ablated regions in the tissue wall, each of the ablated regions in the series positioned one after the other in spatial succession and corresponding to one of the plurality of groups of adjacent transducers, wherein each group of the plurality of groups of adjacent transducers in the distribution has a same transducer as another group of the plurality of groups of adjacent transducers in the distribution, and each group of the plurality of groups of adjacent transducers in the distribution is activated in a sequence that causes at least one of the ablated regions in the series to be formed in a region of the tissue wall that has not been previously ablated, the region in the tissue wall that has not been ablated being positioned between at least two previously formed ones of the ablated regions in the series.
