Abstract
Systems and methods are provided for applying electrical stimulation to a body by an electrode spaced from a target nerve of passage. It has been discovered that pain felt, or perceived to be felt, in a given region of the body can be treated by stimulating muscle close to a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt, such as in a case of post-amputation residual limb pain, or purportedly felt in the case of post-amputation phantom limb pain.
Claims35
A stimulation system comprising:
- an open-coiled wire lead having a thickness and a diameter configured for percutaneous insertion into a portion of a body;
- a plurality of electrodes each formed integrally on the coiled wire lead, wherein the electrodes are spaced apart from one another with an insulated portion positioned between at least two of the plurality of electrodes;
- and
- an electrical stimulation device operatively coupled to the coiled wire lead and configured to apply electrical stimulation through the plurality of electrodes.
A stimulation system comprising:
- a coiled wire lead configured for percutaneous insertion into a body, wherein the coiled wire lead comprises a plurality of electrodes each formed integrally on the coiled wire lead, wherein the electrodes are spaced apart from one another with an insulated portion positioned between at least two of the plurality of electrodes;
- and
- an electrical stimulation device operatively coupled with the coiled wire, wherein the electrical stimulation device is configured to deliver electrical stimulation through the plurality of electrodes to a neural fiber bundle within a body.
A stimulation system comprising:
- a lead comprising at least two electrodes, wherein the at least two electrodes are spaced apart from one another with an insulated portion positioned between them and wherein one of the electrodes is configured to be positioned at a therapeutically effective distance from a neural fiber bundle within tissue, wherein the neural fiber bundle comprises more than one type of nerve fiber;
- and
- an electrical stimulation device operatively coupled with the lead, the electrical stimulation device configured to deliver electrical stimulation from the electrodes to the neural fiber bundle.
A stimulation system comprising:
- a lead comprising at least two non-insulated portions, wherein the at least two non-insulated portion are spaced apart from one another with an insulated portion positioned between them and wherein one of the at least two non-insulated portions is configured to be positioned at a therapeutically effective distance from a neural fiber bundle within tissue, wherein the neural fiber bundle comprises more than one type of nerve fiber;
- and
- an electrical stimulation device operatively coupled with the lead, the electrical stimulation device configured to deliver electrical stimulation to the neural fiber bundle.
