Patent number: 9427571Abstract: An implantable biomedical conductor assembly is configured for at least partial insertion in a living body. The implantable conductor assembly includes an inner tubular structure and an outer tubular structure generally surrounding the inner tubular structures such that a gap of less than about 0.030 inches exists there between. A dynamic coil is located in the gap. The dynamic coil includes a plurality of insulated conductors that are coiled generally at or below a yield point. The insulated conductors are permitted to expand within the gap to engage an inner surface of the outer tubular structure in an expanded coiled configuration. At least one mechanical restraint at each of a distal end and a proximal end retains the dynamic coil in the tubular structures. Free ends of the insulated conductors extend beyond the proximal and distal ends to facilitate attachment to electrodes and connectors.Type: GrantFiled: June 29, 2012Date of Patent: August 30, 2016Assignee: Nuvectra CorporationInventors: Shahn S.
