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.
Claims20
An implantable medical device comprising:
- one or more electrodes;
- a flexible connection component that includes a surface comprised of a set of filaments, wherein:
- the set of filaments includes multiple non-conductive filaments, wherein at least some of the set of filaments are braided or woven together;
- the surface includes a set of conductive elements;
- a set of electrical channels extend across the flexible connection component, each of the set of electrical channels extending across at least one of the set of conductive elements and electrically connected with an electrode of the one or more electrodes;
- circuitry configured to process recorded data transmitted over one or more of the 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.

(canceled)
A method of manufacturing an implantable medical device, the method comprising:
- concurrently pulling each of a set of filaments from a corresponding filament spool to position the pulled set of filaments on a substrate in a braided or woven pattern, wherein the set of filaments includes multiple conductive filaments and multiple non-conductive filaments, and wherein the set of filaments are positioned such that the multiple conductive filaments do not overlap with each other;
- shaping the substrate and positioned pulled set of filaments to form a cylindrical shape;
- and
- for each conductive filament of the multiple conductive filaments:
- forming an electrical connection between a first end of the conductive filament and an electrode;
- and
- forming an electrical connection between a second end of the conductive filament and circuitry.
