Classification: CPC A | IPC A

Claim 0:
1. A medical device system comprising:
a structure;
a plurality of transducers located on the structure;
a shaft member configured to percutaneously deliver the structure to a location within a patient, the shaft member comprising a distal end portion and a proximal end portion, at least part of the shaft member sized to be percutaneous deliverable toward the location within the patient distal end portion ahead of the proximal end portion;
a plurality of conductors coupled to the plurality of transducers, at least a portion of each conductor of the plurality of conductors located within the shaft member; and
a controller operatively coupled to the plurality of transducers and configured to cause delivery of electrical power to the plurality of transducers via the plurality of conductors,
wherein the controller is configured to cause delivery, via a first set of the plurality of conductors, of first electrical power to a transducer set of the plurality of transducers, the first electrical power sufficient to cause, if delivered for a first time period, a portion of the shaft member to transition from a first temperature to a steady-state temperature immediately upon conclusion of the first time period, the steady-state temperature determined sufficient to cause thermally-induced tissue cellular damage,
wherein the controller is configured to cause delivery of the first electrical power to the transducer set for a maximum of a second time period, the second time period shorter than the first time period, and the delivery of the first electrical power to the transducer set for the second time period (a) sufficient to cause tissue ablation via the transducer set, and (b) sufficient to cause the portion of the shaft member to transition from the first temperature to a second temperature immediately upon conclusion of the second time period, and
wherein the controller is configured to determine the second temperature, which is less than the steady-state temperature and determined insufficient to cause thermally-induced tissue cellular damage.
