Abstract
A lead assembly includes a lead with a distal end and a proximal end. The lead includes a plurality of electrodes disposed at the distal end and a plurality of terminals disposed at the proximal end. The lead also defines at least one central lumen and a plurality of outer lumens. The central and outer lumens extend from the proximal end to the distal end such that the plurality of outer lumens extend laterally from the at least one central lumen. The lead further includes a plurality of conductive wires. Each conductive wire couples at least one of the plurality of electrodes electrically to at least one of the plurality of terminals. At least two conductive wires are disposed in each of the plurality of outer lumens.
Claims20
An electrical stimulation system, comprising
- a control module comprising
- a housing,
- an electronic subassembly disposed in the housing, and
- a connector comprising
- a connector housing defining at least one port, and
- a plurality of connector contacts disposed in the connector housing;
- and
- a lead electrically coupleable to the control module, the lead comprising:
- a lead body with a distal end, a proximal end, and a longitudinal length;
- a plurality of electrodes disposed along the distal end of the lead body;
- a plurality of terminals disposed along the proximal end of the lead body;
- a central lumen defined by the lead body and extending from the proximal end of the lead body;
- a plurality of conductive wires extending along the longitudinal length of the lead body and electrically coupling the electrodes to the terminals;
- and
- a rod permanently disposed within the central lumen at the proximal end of the lead body to stiffen the proximal end of the lead body to facilitate insertion of the proximal end of the lead body into the connector of the control module, wherein the rod is hollow and defines a lumen extending along a length of the rod;
- wherein at least one of the at least one port of the connector housing is configured for receiving the proximal end of the lead body.
A lead, comprising:
- a lead body with a distal end, a proximal end, and a longitudinal length;
- a plurality of electrodes disposed along the distal end of the lead body;
- a plurality of terminals disposed along the proximal end of the lead body;
- a central lumen defined by the lead body and extending from the proximal end of the lead body;
- a plurality of conductive wires extending along the longitudinal length of the lead body and electrically coupling the electrodes to the terminals;
- a rod disposed within the central lumen at the proximal end of the lead body to stiffen the proximal end of the lead body to facilitate insertion of the proximal end of the lead body into a connector, the rod extending radially beneath at least one of the terminals;
- and
- a cap physically and permanently attached to the rod and disposed outside of, and proximal to, the proximal end of the lead body.
