Systems and methods for evaluating neuromodulation therapy via hemodynamic responses

Abstract

Systems and methods for evaluating neuromodulation via hemodynamic responses are disclosed herein. A system configured in accordance with embodiments of the present technology can include, for example, a neuromodulation catheter comprising an elongated shaft having a distal portion, and a plurality of electrodes spaced along a distal portion. The system can further include a controller communicatively coupled to the electrodes. The controller can be configured to apply first and second stimuli at and/or proximate to a target site within a blood vessel before and after delivering neuromodulation energy to the target site, and detect, via at least one of the electrodes, vessel impedance resulting from the first and second stimuli to determine a baseline impedance and a post-neuromodulation impedance. The controller can further be configured to assess the efficacy of the neuromodulation based, at least in part, on a comparison of the baseline impedance and the post-neuromodulation impedance.
