Abstract
A medical device includes telemetry circuitry configured to receive programming instructions. The medical device also includes stimulation circuitry configured to generate a plurality of electrical pulses in response to the programming instructions to provide an electrical stimulation therapy for a patient. The stimulation circuitry includes a voltage converter, a multiplexor, and a stimulation driver. At least one of the voltage converter, the multiplexer, or the stimulation driver is selectively enabled and disabled during or between the electrical pulses to reduce power consumption of the medical device.
Claims20
A medical device, comprising:
- telemetry circuitry configured to receive programming instructions;
- and
- stimulation circuitry configured to generate a plurality of electrical pulses in response to the programming instructions to provide an electrical stimulation therapy for a patient;
- wherein:
- the stimulation circuitry includes a voltage converter, a multiplexor, and a stimulation driver;
- and
- at least one of the voltage converter, the multiplexer, or the stimulation driver is selectively enabled and disabled during or between the electrical pulses to reduce power consumption of the medical device.
A medical system, comprising:
- an electronic programmer configured to generate stimulation programming instructions;
- an implantable pulse generator (IPG) configured to receive the stimulation programming instructions to generate electrical pulses as a part of a stimulation therapy for a patient;
- and
- a lead configured to deliver the electrical pulses to the patient;
- wherein:
- the IPG includes a voltage converter, a multiplexor, a stimulation driver, and a microcontroller;
- and
- the microcontroller is configured to automatically generate control signals to selectively enable and disable the voltage converter, the multiplexer, or the stimulation driver during the stimulation therapy to reduce power consumption of the IPG.
A method, comprising:
- receiving programming instructions via telemetry circuitry of a pulse generator;
- and
- generating, via stimulation circuitry of the pulse generator that includes a voltage converter, a multiplexor, and a stimulation driver, a plurality of electrical pulses in response to the programming instructions to provide an electrical stimulation therapy for a patient, wherein the generating comprises automatically enabling and disabling the voltage converter, the multiplexor, or the stimulation driver during or between e electrical pulses to reduce power consumption of the pulse generator.
