Benefits of technology

[0006]In yet another embodiment, a method for stimulating patient brain tissue includes implanting a lead into a brain of a patient. The lead includes a plurality of electrodes disposed on a distal end. The distal end has a non-circular transverse cross-sectional shape. The plurality of electrodes are electrically coupled to a plurality of terminals disposed on a proximal end. A plurality of conductive wires electrically couple at least one terminal to at least one electrode. The proximal end...

Problems solved by technology

The precise insertion of the stimulating lead and positioning of the stimulating lead in the precise location indicated by the recording lead can be particularly difficult.

Embodiment Construction

[0033]The present invention is directed to the area of brain stimulation systems and methods of making and using the systems. The present invention is also directed to brain stimulation systems that include leads with distal ends that have non-circular transverse cross-sectional shapes configured and arranged to limit stimulation to one or more stimulation regions, as well as methods of making and using the leads and brain stimulation systems.

[0034]A lead for deep brain stimulation can include both recording and stimulation electrodes. This allows a practitioner to determine the position of the target structures, such as neurons, using the recording electrode(s) and then position the stimulation electrode(s) accordingly without removal of a recording lead and insertion of a stimulation lead. A lead can also include recording electrodes spaced around the circumference of the lead to more precisely determine the position of the target structures. In at least some embodiments, the lead...

Abstract

A lead is configured and arranged for brain stimulation. The lead includes a proximal end and a distal end. The proximal end includes a plurality of terminals disposed at the proximal end. The distal end has a non-circular transverse cross-sectional shape and includes a plurality of electrodes disposed at the distal end. A plurality of conductive wires electrically couple at least one of the plurality of electrodes to at least one of the plurality of terminals.

Description

TECHNICAL FIELD[0001]The present invention is directed to the area of brain stimulation systems and methods of making and using the systems. The present invention is also directed to brain stimulation systems that include leads with distal ends that have non-circular transverse cross-sectional shapes configured and arranged to limit stimulation to one or more discrete stimulation regions, as well as methods of making and using the leads and brain stimulation systems.BACKGROUND[0002]Deep brain stimulation can be useful for treating a variety of conditions including, for example, Parkinson's disease, dystonia, essential tremor, chronic pain, Huntington's Disease, levodopa-induced dyskinesias and rigidity, bradykinesia, epilepsy and seizures, eating disorders, and mood disorders. Typically, a lead with a stimulating electrode at or near a tip of the lead provides the stimulation to target neurons in the brain. Magnetic resonance imaging (“MRI”) or computerized tomography (“CT”) scans c...
