Patent ID: 8892214

Claim:
An implantable medical electrical lead for applying an electrical stimulation energy to bodily tissue of a patient from a power source located external the patient, the lead defined by a distal section, an intermediate section, and a proximal section, and the lead comprising: a lead body corresponding to the distal section, the lead body extending from a proximal end thereof to a distal end thereof, and the lead body comprising a plurality of stimulating electrodes arranged in an electrode array that extends proximally from the distal end of the lead body, and an anchoring device that extends between the electrode array and the proximal end of the lead body; a plurality of coiled wire lead conductors disposed within the lead body and defining a lead body lumen that extends distally from an opening thereof at the proximal end of the lead body, each of the coiled wire lead conductors including a distal end, each coiled wire lead conductor distal end being coupled to a corresponding electrode of the electrode array; a plurality of insulated conductor wires electrically insulated from one another, each conductor wire including a distal segment, an intermediate segment, and a proximal segment, each distal segment being coupled to a corresponding coiled wire lead conductor within the lead body, the intermediate segments corresponding to the intermediate section of the lead and extending proximally from the proximal end of the lead body, and the proximal segments corresponding to the proximal section of the lead, and each intermediate segment having a non-coiled configuration and not being exteriorly encompassed by any separate body, such that a clinician can bend or curve each wire, along the intermediate segment thereof, to any desired spatial orientation, and the intermediate segments are extendable through a patient's skin and sealable relative thereto; and a plurality of connector elements formed in a connector array at the proximal section, each of the connector elements being electrically coupled to, and terminating a corresponding wire proximal segment.
