Abstract

Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

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.

2. The method of claim 1 wherein the at least one of the ablated regions in the series is spatially separated from at least one of the at least two previously formed ones of the ablated regions in the series.

3. The method of claim 1 wherein each of the ablated regions in the series is positioned one after the other in spatial succession to form a continuous ablated region.

4. The method of claim 3 wherein the continuous ablated region circumferentially encloses a region of the tissue wall.

5. The method of claim 3 wherein the continuous ablated region circumferentially encloses a port of a bodily opening that interrupts the tissue wall.

6. The method of claim 1 wherein each of the ablated regions in the series is adjacently positioned in the series between a respective pair of ablated regions in the series.

7. The method of claim 1 wherein the energy from the energy source device system delivered to each of the transducers in each group of the plurality of groups of adjacent transducers in the distribution is configured to cause bipolar tissue ablation.

8. The method of claim 1 wherein the energy from the energy source device system delivered to each of the transducers in each group of the plurality of groups of adjacent transducers in the distribution is configured to cause monopolar tissue ablation.

9. A catheter device system comprising:

an energy source device system;

a 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; and

a data processing device system connected to at least the energy source device system and configured at least to:

activate 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, the energy sufficient 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.

10. The catheter device system of claim 9 wherein the at least one of the ablated regions in the series is spatially separated from at least one of the at least two previously formed ones of the ablated regions in the series.

11. The catheter device system of claim 9 wherein each of the ablated regions in the series is positioned one after the other in spatial succession to form a continuous ablated region.

12. The catheter device system of claim 11 wherein the continuous ablated region circumferentially encloses a region of the tissue wall.
