Patient treatment systems for sensing cardiac depolarization and/or stimulating the carotid sinus nerve, and associated devices and methods

Abstract

Patient treatment systems and methods for sensing cardiac depolarization and/or stimulating the carotid sinus nerve are disclosed herein. Exemplary patient treatment systems can include a neuromodulator and an implantable signal delivery device electrically coupleable to the neuromodulator. The signal delivery device comprises a lead body including a first region, a second region positionable over the first region, and lead electrodes. The patient treatment system further comprises computer-readable media having instructions that cause the patient treatment system to perform operations comprising: (i) obtaining a physiological parameter of the patient, (ii) generating neuromodulation pulses based on the obtained physiological parameter, and (iii) delivering the neuromodulation pulses to the CSN afferent fibers via one or more of the lead electrodes. The physiological parameter can include at least one of blood pressure, heart rate, bioimpedance, or activity level of the patient.
