HYPERTENSION THERAPY DEVICE WITH LONGEVITY MANAGEMENT

摘要

System and methods for programming and delivering electrical stimulation to treat hypertension are discussed. In various embodiments, an ambulatory stimulator system, such as an implantable medical device, can receive a power-saving command and deliver the electrical stimulation to a target site in a patient according to one or more simulation parameters including a therapy on-off pattern. In some embodiments, stimulation with therapy on-off pattern can reduce the power consumption while maintaining the anti-hypertension therapy efficacy. In some embodiments, the ambulatory stimulator system can include one or more of a physiologic response detector, a patient status detector, or a battery longevity detector. The power-saving command can be generated using one or more of the detected physiologic signal, the patient status, or the information about the battery longevity.

主权项

1. A system for treating hypertension, comprising:
a stimulator configured to generate stimulation pulses; a memory circuit configured to store one or more stimulation parameters including a therapy-on period during which the stimulation pulses are programmed to be delivered, a therapy-off period during which no stimulation pulse is programmed to be delivered, and a therapy on-off pattern including a combination of a sequence of therapy-on periods with variable durations and a sequence of therapy-off periods with variable durations; and a controller circuit connected to the stimulator and the memory circuit, the controller circuit configured to: receive a power-saving command; time one or both of the therapy-on period and the therapy-off period; and schedule the delivery of the stimulation pulses to a target site according to the therapy on-off pattern in response to a power-saving command.
