Abstract
A lead assembly includes a flexible lead body extending from a proximal end to a distal end, and the lead body includes two or more conductors disposed therein. The second conductor is disposed within the first conductor, and the first conductor has a coating of insulation disposed on a portion thereof. In another option, a sleeve of insulative material is disposed between the first conductor and the second conductor.
Claims17
A lead assembly comprising:
- a lead body extending from a proximal end to a distal end, the lead body including two or more co-axial and non co-radial conductors disposed therein;
- the two or more co-axial and non co-radial conductors including a first conductor and a second conductor, the second conductor disposed within, and rotatable relative to, the first conductor;
- the first conductor including one or more filars having a coating of insulation disposed directly on an outer surface portion thereof;
- and
- an electrode assembly including at least one extendable and/or retractable electrode electrically coupled with at least one of the conductors.
