Abstract
Methods and devices for stimulating a nerve in a patient include emitting an electrical signal near a spinal nerve within the patient such that the patient experiences at least some pain relief. The methods include varying an electric field such that burst periods and constant periods are created. The electric field has a charge that alternates between positive and negative during the burst periods and a charge with a magnitude of zero during the constant periods.
Claims11
A method comprising:
- generating an electrical signal within a housing having a lead extending therefrom;
- varying the electric field with a signal generator within the housing such that burst periods and constant periods are created, wherein the electric field has a charge that alternates between positive and negative during the burst periods, wherein the charge of the electric field alternates between positive and negative 2 times to 20 times during each burst period, and wherein the charge of the electric field is constant during each constant period;
- positioning the lead near, or in operational proximity to, a spinal nerve within a patient;
- and
- emitting the electrical signal via the lead towards the spinal nerve such that an electric field is generated near the spinal nerve such that the patient experiences at least some pain relief.

A device comprising:
- a housing;
- a lead extending from the housing, wherein the lead is configured to be positioned near, or in operational proximity to, a spinal nerve;
- and
- a source of energy positioned within the housing, wherein the source of energy is operably coupled to the lead;
- a signal generator configured for generating an electrical field such that the electrical field is emitted via the lead towards the spinal nerve such that that a patient experiences at least some pain relief, wherein the signal generator is configured to vary the electrical field to create burst periods and constant periods, wherein the electric field has a charge that alternates between positive and negative during the burst periods, wherein the charge of the electric field alternates between positive and negative 2 and 20 times during each burst period and wherein the charge of the electric field is constant during each constant period.
