Abstract
Embodiments relate to an implantable device. Specifically, a device includes a flexible connection component that includes a set of conductive filaments that connect a set of electrodes (or traces connected to the electrodes) and circuitry that receives and/or transmits electronic signals from and/or to the electrodes.
Claims18
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.

A method of manufacturing an implantable medical device, the method comprising:
- providing a thin film defining an array portion and a flexible connection portion;
- providing one or more electrodes disposed on the array portion;
- providing a set of filaments including multiple non-conductive filaments and multiple conductive filaments, 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;
- concurrently pulling each filament of the set of filaments from a corresponding filament spool to position a pulled set of filaments on the flexible connection portion of the thin film, wherein at least some of the multiple non-conductive filaments and the multiple conductive filaments are braided or woven together and positioned such that the conductive filaments do not overlap with each other;
- providing a circuitry 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;
- shaping the thin film and the positioned pulled set of filaments to form a cylindrical shape;
- and
- for each of the multiple conductive filaments:
- forming an electrical connection between a first end of the conductive filament and a corresponding electrode of the one or more electrodes to operate as an electrical channel of the set of electrical channels and transmit data from the corresponding electrode to the circuitry and/or output control signals from the circuitry to the corresponding electrode;
- and
- forming an electrical connection between a second end of the conductive filament and the circuitry via a corresponding electrical interface of one or more electrical interfaces.
