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.
Claims20
A neurostimulation lead or lead extension comprising:
- a lead body having a proximal end and a distal end;
- a plurality of first contacts disposed on the distal end of the lead body;
- a plurality of second contacts 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 first contacts to at least one of the second contacts, wherein at least one of the conductors comprises at least one switch disposed along a length of the conductor, wherein 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.
A neurostimulation system, comprising:
- a 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 at least one switch disposed along a length of the conductor and configured and arranged to separate the conductor into a plurality of individual segments when the at least one switch is opened;
- and
- a control module configured and arranged for coupling to the lead and to provide electrical stimulation signals to a patient through the electrodes of the lead.
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 at least one switch disposed along a length of the conductor and configured and arranged to separate the conductor into a plurality of individual segments when the at least one switch is opened;
- providing signals to the electrodes to produce neural stimulation of tissue in the patient;
- and
- opening the at least one switch when an intensity from at least one of a magnetic field or radio-frequency radiation meets a threshold criterion.
