Abstract: A hermetic electronics package of a multi-electrode neural prosthesis system includes a metal case, a feedthrough construction having an electrically insulating substrate and an array of electrically conductive feedthroughs extending through it, with the electrically insulating substrate connected to the open end of the metal case to form a hermetically sealed enclosure. And a set of electronic components is located within the hermetically sealed enclosure and operably connected to the feedthroughs of the feedthrough construction so as to electrically communicate outside the package. And a demultiplexer is fsoperatively connected to demultiplex a single signal into multiple signals prior to being transmitted through the feedthroughs.

Abstract: A rigid spine-reinforced microelectrode array probe and fabrication method. The probe includes a flexible elongated probe body with conductive lines enclosed within a polymeric material. The conductive lines connect microelectrodes found near an insertion end of the probe to respective leads at a connector end of the probe. The probe also includes a rigid spine, such as made from titanium, fixedly attached to the probe body to structurally reinforce the probe body and enable the typically flexible probe body to penetrate and be inserted into tissue, such as neural tissue. By attaching or otherwise fabricating the rigid spine to connect to only an insertion section of the probe body, an integrally connected cable section of the probe body may remain flexible.
