Patent Images
1. A stereotactic system, adapted for attachment to the skull of a subject, comprising:
- a skull guide with a plurality of pilot holes and at least two stand-off posts for attachment to the skull;
one or more implant shuttles, for insertion into the pilot holes, comprising a sheath that aligns with and is supported by the pilot hole and an electrode; and
a stereotactic device that engages with the skull guide, the stereotactic device comprising;
a lower housing with sidewalls and an aperture that leads into a chamber, such that the skull guide is inserted into the chamber through the aperture;
a mounting socket configured on the lower housing having one or more conformations, adapted to attach a secondary device to the implant shuttles; and
an upper housing for placement over the lower housing with a cover section that extends over the chamber and an orifice for receiving the mounting socket therethrough.

Abstract
A stereotactic system with customizable and interoperable components for implantation of intracranial implants is provided. The stereotactic system can include a NeuroHat stereotactic device that attaches directly to the skull of an animal subject to protect chronic intracranial implants without interfering with the normal activities of the animal subject. The stereotactic system can also include a drill guide for accurate placement of burr holes and implant shuttles designed to be interoperable with other components of the NeuroHat stereotactic device for accurate placement and secureability.

19. A stereotactic system, adapted for attachment to the skull of a subject, comprising:
-
a skull guide with a plurality of pilot holes and at least two stand-off posts for attachment to the skull; one or more implant shuttles, for insertion into the pilot holes, comprising a sheath that aligns with and is supported by the pilot hole, an electrode, and stopper for controlling the depth of the electrode, and one or more attachment mechanisms on the stopper for attachment of secondary components; and a stereotactic device that engages with the skull guide, the stereotactic device comprising; a lower housing with sidewalls, an aperture at the posterior end that leads into a chamber, such that the skull guide is inserted into the chamber through the aperture, at least one hole by which the lower housing is attachable to the skull, and a side port in communication with the at least one hole; a mounting socket configured on the lower housing comprising one or more conformations, adapted to attach a secondary device to the one or more implant shuttles, and a removable access plate for covering the conformations; and an upper housing for placement over the lower housing that at least partially surrounds the lower housing sidewalls, a cover section at the anterior end that extends over the chamber and an orifice at the posterior end through which the mounting socket extends distally therethrough, wherein the sidewalls of the lower housing rise to at least the height of the distal end of an implant shuttle inserted into a pilot hole in the skull guide, wherein the stereotactic system further comprises enhancement on the at least two standoff posts of the skull guide to aid in securing the standoff posts to the skull, and wherein the stereotactic system further comprises a drill guide having; a drill support, adapted to receive and support a drill; and a jig, proximal to the drill support, that includes a post on a proximal side of the jig that engages with a pilot hole in the skull guide and is adapted to guide a drill bit through the pilot hole.
