An implantable device has a hermetically sealed enclosure, an electronic device within the hermetically sealed enclosure, and a plurality of feedthrough conductors in mechanical contact with the hermetically sealed enclosure and exposed outside of the hermetically sealed enclosure. The implantable device also has a flexible substrate with a plurality of therapy contacts, and a plurality of continuously conductive elements extending along the flexible substrate from the array of therapy contacts and terminating at a plurality of connection pads. Each of the continuously conductive element is integral with at least one therapy contact and at least one connection pad to electrically communicate the noted therapy contact(s) and the noted connection pad(s). The thickness of each continuously conductive element may be between about 5 and 190 microns. The implantable device also has a plurality of mechanical welded couplings that each couple at least one of the connection pads.

Implantable devices with welded multi-contact electrodes and continuous conductive elements and method

An electrode array system includes a unitary body forming a plurality of apertures, and a plurality of continuous conductive elements at least partially encapsulated within the unitary body. The continuous conductive elements include/form a plurality of contacts, a plurality of electrode sites configured to couple with neural tissue (e.g., a spinal nerve or peripheral nerve), and a plurality of interconnects extending between the plurality of contacts and the plurality of electrode sites. The plurality of electrode sites are aligned with the plurality of apertures, and the plurality of apertures expose the plurality of electrodes.

Multi-electrode array with unitary body

Implantable devices with welded multi-contact electrodes and continuous conductive elements

A method assists a person by providing an electrode array having a substrate supporting a plurality of stimulation contacts configured to stimulate at least a portion of the spinal cord neural tissue. The method also implants, in a medically uncompressed manner, the therapy array in the epidural space, where a portion of the therapy array is positioned adjacent to at least one pedicle with stimulation contacts positioned adjacent to at least one dorsal root laterally and at least one fasciculi of the dorsal column within the vertebral foramen at one or more vertebral levels.
