Abstract
Ablation probes and methods of their use. Example probes include probe circuits configured to provide identifying information for the probe itself. The probe circuits may sense probe usage and/or age to determine probe end of life (EOL). In response to EOL, the probe circuit generates an output indicating EOL. The probe electronic circuit may also be configured to monitor probe usage via impedance or other features, independent of such operation by an ablation pulse generator.
Claims6
An ablation probe configured for use with an ablation generator, comprising:
- a distal end having one or more electrodes thereon for delivering therapy directed at target tissue;
- a proximal end having one or more contacts thereon for coupling to the ablation generator;
- an elongated body between the proximal and distal ends carrying at least one conductor that electrically couples at least one electrode to at least one contact;
- a probe electronic circuit in or on the probe and configured to obtain power from the ablation generator and sense one or more characteristics of usage of the probe, quantify the one or more characteristics, and record or transmit data related to the sensed and quantified one or more characteristics;
- and
- an electronic indicator providing visual feedback to a user of the probe, the electronic indicator being located on the probe and separate from a user interface of the ablation generator, wherein the electronic circuit is coupled to the electronic indicator to allow the data to be displayed to a user via the electronic indicator;
- wherein the electronic circuit obtains power from the ablation generator by harvesting power from therapeutic signals transmitted to the distal end of the probe by the ablation generator via the conductor.
