Electrical stimulation leads having RF compatibility and methods of use and manufacture
First Claim
1. A method of neural stimulation, the method comprising:
- implanting a lead in a patient, the lead comprising a lead body having a proximal end and a distal end, a plurality of electrodes disposed on the distal end of the lead body, a plurality of terminals disposed on the proximal end of the lead body, and a plurality of conductors extending along the lead body, wherein each of the plurality of conductors electrically couples at least one of the electrodes to at least one of the terminals, wherein at least one of the conductors comprises a plurality of switches disposed along a length of the conductor and configured and arranged to separate the conductor into a plurality of individual segments when the plurality of switches are opened;
providing signals to the electrodes to produce neural stimulation of tissue in the patient; and
opening the plurality of switches when an intensity from at least one of a magnetic field or radio-frequency radiation meets a threshold criterion.

Abstract
A neurostimulation lead or lead extension includes a lead body having a proximal end and a distal end. A plurality of first contacts are disposed on the distal end of the lead body. A plurality of second contacts are disposed on a proximal end of the lead body. A plurality of conductors extend along the lead body. Each of the plurality of conductors electrically couples at least one of the first contacts to at least one of the second contacts. At least one of the conductors includes at least one switch disposed along a length of the conductor. The at least one switch is configured and arranged to separate the conductor into a plurality of individual segments when the at least one switch is opened.
