Abstract

In some preferred embodiments, without limitation, the present invention comprises an implantable, intracranial neural interface node which is an integrated and minimally invasive platform system and supports cross-modal neural interfaces to the cerebrum and other associated structures in the central nervous system. The neural interfaces comprise electrical and chemical interfaces for neural recording, electrical stimulation, chemical delivery, chemical sensing, chemical sampling, cell delivery, genetic material delivery and/or other functions of interest.

Claims

1. An implantable neural interface node comprising:

a chamber insertable into a mammalian cranium;

at least one lumen within the chamber; and

at least one neuroprobe assembly.

2. The implantable neural interface node of claim 1, further comprising at least one electronic interface.

3. The implantable neural interface node of claim 2, further comprising at least one electronic interface comprised of a rim circuit board on a shelf within the chamber.

4. The implantable neural interface node of claim 1, further comprising at least one electronic interface connected to at least one neuroprobe assembly.

5. The implantable neural interface node of claim 4, further comprising a flexible interconnect cable that connects at least one electronic interface to at least one neuroprobe assembly.

6. The implantable neural interface node of claim 1, further comprising a lumen plug.

7. The implantable neural interface node of claim 1, further comprising at least one or more fluidic components.

8. An implantable neural interface node comprising:

a chamber comprised of a cranial insert piece and a top piece;

at least one lumen within the cranial insert piece;

at least one electronics interface; and

at least one neuroprobe assembly connected to at least one electronics interface.
