1. An implantable medical device comprising:
a thin film defining an array portion and a flexible connection portion;
one or more electrodes disposed on the array portion;
a set of filaments disposed on the flexible connection portion, the set of filaments including multiple non-conductive filaments, and multiple conductive filaments, wherein at least some of the multiple non-conductive filaments and the multiple conductive filaments are braided or woven together;
a circuitry configured to process recorded data transmitted over one or more electrical channels of a set of electrical channels and/or to output control signals that identify stimulation parameters to be communicated over at least one of the set of electrical channels; and
one or more electrical interfaces, wherein each electrical interface of the one or more electrical interfaces is configured to connect an end of an electrical channel of the set of electrical channels with the circuitry,
wherein some of the conductive filaments are configured to electrically connect with a corresponding electrode to operate as an electrical channel of the set of electrical channels and transmit data from the electrode to the circuitry and/or output control signals from the circuitry to the electrode, and
wherein each of the multiple conductive filaments includes multiple monofilament fibers, each of the multiple monofilament fibers includes a non-conductive core formed from a thin-film material with a conductive material disposed on the thin-film material.
