Devices, systems and methods for evaluation and feedback of neuromodulation treatment
First Claim
1. A method for neuromodulation treatment of a human patient, the method comprising:
- delivering energy over a first period of time, via an electrode positioned at a treatment site within a blood vessel of the patient, to target neural fibers adjacent a wall of the blood vessel;
maintaining energy delivery at a first predetermined power level for a second period of time;
increasing energy delivery to a second predetermined power level if a temperature value sensed in or near the electrode is less than a preset threshold temperature following the second period of time;
obtaining a set of treatment data corresponding to a completed neuromodulation treatment;
evaluating the set of treatment data in view of one or more criteria to determine if a valuation of the completed neuromodulation treatment is within a pre-determined range; and
providing an indication as to whether the valuation of the completed neuromodulation treatment is within the pre-determined range.

Abstract
The present disclosure relates to devices, systems and methods for evaluating the success of a treatment applied to tissue in a patient, such as a radio frequency ablative treatment used to neuromodulate nerves associated with the renal artery. A system monitors parameters or values generated during the course of a treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of the likelihood that a completed treatment was technically successful. In other embodiments, parameters or values generated during the course of an incomplete treatment (such as due to high temperature or high impedance conditions) may be evaluated to provide additional instructions or feedback to an operator.

19. A method for renal neuromodulation treatment of a human patient via an electrode positioned within a renal artery of the patient, the method comprising:
-
delivering radio frequency (RF) energy, via the electrode, to target renal nerves proximate the renal artery, wherein delivering RF energy comprises— increasing energy delivery to the electrode a predetermined first power level over a first period of time; maintaining energy delivery at the predetermined first power level for a second period of time; and increasing energy delivery to a predetermined second power level if the temperature value measured in or near the electrode is less than a preset threshold temperature following the second period of time, wherein the increase in energy delivery following the second period of time continues until the power level has reached a target maximum power threshold; and evaluating the renal neuromodulation treatment of the patient, wherein the evaluation comprises— obtaining a set of treatment data corresponding to a completed renal neuromodulation treatment; evaluating the set of treatment data in view of one or more criteria to determine if a valuation of the completed renal neuromodulation treatment is within a pre-determined range; and providing an indication as to whether the valuation of the completed renal neuromodulation treatment is within the pre-determined range. - View Dependent Claims (20, 21)
