International Classification:

A61B 5/0476
A61N 1/36

US Classification:

600544, 607 45, 600300

Abstract:

The invention includes a recordation and stimulation system for determining and delivering an electrical stimulation treatment based upon the current status of neuronal activity of a subject. The system include components for detecting neuronal activity in a subject's brain and, based upon the information received, determine an appropriate electrical stimulation treatment for the subject. The system allows immediate adjustments to the stimulation treatment as the needs of the subject change over time. The invention also includes a method for determining whether a subject has early Parkinson's Disease or advanced Parkinson's Disease. The method includes the steps of acquiring information regarding neuronal discharges in certain areas of the brain, creating a ratio based upon the neuronal activity, and determining whether a previous medical diagnosis of Parkinson's Disease is accurate.

Abstract:

Described herein is a cranial surgery drill bit having a safety self stopping mechanism for use on bone material to prevent or repair skin erosion and infection which may result from the placement of a cap for holding the lead from Deep Brain Stimulation surgery. The surgical procedure of attaching a lead holding cap onto the bone material of a skull requires an attachment which results in no movement of the lead. Accordingly, counter boring the skull surrounding a pre-existing perforation bore so that the cap is not significantly above the surface of the skull is a technique which allows the cap user to brush hair, etc. , without disrupting the attachment and placement of the lead.

International Classification:

A61B 90/11
A61B 90/14

Abstract:

A stereotactic system for positioning a device relative to a spine includes a first frame with an attached first pedicle screw, a second frame with an attached second pedicle screw, and a platform for mounting the device. The lower parts of the frames are horizontally spaced apart, and attachable to the spine by the pedicle screws. The platform is attached to the upper parts of the frames and supported by the frames above the spine. The platform is slidably attached to the upper parts of the frames to adjust a longitudinal position of the platform relative to the frames. The platform is pivotally attached to the upper parts of the frame to adjust a horizontal distance between the lower parts of the frames, while maintaining a constant orientation of the platform.
