1. A method of treating heart failure, comprising:

  • causing a baroreflex therapy system to be manufactured and made available to a user, the baroreflex therapy system configured to be implanted within a patient;

    causing an implantable measurement device to be manufactured and made available to the user, the implantable measurement device configured to be implantable proximate a blood vessel of the patient, the implantable measurement device including a plurality of electrodes; and

    causing a control system to be manufactured and made available to the user, the control system configured to be coupled to the baroreflex therapy system and the implantable measurement device, the control system programmed to automatically;

    determine an impedance of the blood vessel with the implantable measurement device over a time period of at least one cardiac cycle;

    generate at least one signal representative of a pressure waveform based on the impedance;

    activate, deactivate or otherwise modulate the baroreflex therapy system to deliver a therapy to treat heart failure based at least in part on the at least one signal representative of the pressure waveform.
