Abstract
An implantable, substantially isodiametric, low resistance implantable lead having at least one electrode positioned in a stimulation/sensing portion of the lead. At least the stimulation/sensing portion is unitized through partially surrounding and supporting insulation and conductive element(s) of the stimulation/sensing portion with a fused matrix of material having mechanical properties consistent with a body of the lead.
Claims14
An implantable lead comprising:
- a lead body having a distal end and a proximal end, wherein the lead body is formed of a material having prescribed mechanical properties;
- a first region extending distally from the distal end of the lead body, wherein the first region includes a plurality of electrodes, and adjacent electrodes are separated by a first insulative material having mechanical properties consistent with the material of the lead body;
- a second region extending proximally from the proximal end of the lead body, wherein the second region includes at least one terminal, and when the implantable lead includes a plurality of terminals, adjacent terminals are separated by a second insulative material having mechanical properties consistent with the material of the lead body;
- and
- at least one conductor electrically coupling each terminal with at least one corresponding electrode of the plurality of electrodes, wherein each conductor extends along an interior passage defined within the lead body, first region, and second region,
- wherein in addition to the at least one conductor, the interior passage of the first region is substantially filled with a third insulative material having mechanical properties consistent with the material of the lead body.
