Abstract
Systems and methods for performing and controlling ablation therapy. Examples provide adaptive therapy outputs that allow a user to select among various feedback parameters, parameter limits, and therapy profiles, to be implemented by an ablation system. The ablation system adaptively issues therapy by monitoring one or more feedback parameters to determine changes to make to therapy outputs.
Claims20
A system for controlling an ablation therapy comprising:
- a signal generator adapted to provide electrical output for ablation therapy;
- and
- a user interface operatively linked to the signal generator, the user interface configured to interact with a user by:
- providing the user a list of available closed loop control parameters to select from;
- receiving from the user a selection of one or more closed loop control parameters;
- and
- for at least one user selected closed loop parameter, presenting the user with an input screen for selecting or approving one or more limits for the user selected closed loop parameter;
- further wherein the signal generator is configured to deliver a therapy regimen as follows:
- generating a first electrical output having a first output parameter set;
- sensing a signal related to the user selected closed loop parameter and comparing the sensed signal to the user selected or approved limit for the user selected closed loop parameter;
- adjusting the first output parameter set to create a second output parameter set;
- and
- generating a second electrical output using the second output parameter set, wherein at least the second output parameter set is configured for ablating tissue.
