  • Publication number: 20230398380
    Abstract: A workflow has been developed that enables initially mapping of a focused ultrasound (FUS) beam using magnetic resonance (MR) thermometry or MR-acoustic radiation force imaging (MR-ARFI) while working within the MRI device. During this procedure, key measurements will be taken including the precise location of the transducer relative to the skull and the transducer parameters (such as amplitudes and phases) required to place the ultrasound focus at the desired focal size and location in the skull. The anatomical measurements will be used to build a patient-specific, device-specific stereotactic frame to hold the transducer in the position relative to the skull and the aberration corrects will be applied. FUS therapy can then be delivered to the patient outside of the MR environment.

  • Patent number: 9044596
    Abstract: Certain aspects of the present disclosure are directed to a method of applying infrared neural stimulation (INS) to the central nervous system (CNS) of a target. The methods includes applying a pulsed infrared laser at a stimulation site in the CNS; and evoking responses from a region of interest of the CNS that is at or adjacent to the stimulation site by the pulsed infrared laser. In the method, the pulsed infrared laser penetrates a predetermined penetration depth of the stimulation site. Certain aspects of the present disclosure are directed to an apparatus for applying INS to the CNS of a target. The apparatus includes a generator generating a pulsed infrared laser, which penetrates a predetermined penetration depth of a stimulation site to evoke a response from the CNS, and an optical medium adapted for delivering the pulsed infrared laser at the stimulation site of the CNS.

  • Patent number: 8498699
    Abstract: An apparatus and method for stimulating animal tissue (for example to trigger a nerve action potential (NAP) signal in a human patient) by application of both electrical and optical signals for treatment and diagnosis purposes. The application of an electrical signal before or simultaneously to the application of a NAP-triggering optical signal allows the use of a lower amount of optical power or energy than would otherwise be needed if an optical signal alone was used for the same purpose and effectiveness. The application of the electrical signal may precondition the nerve tissue such that a lower-power optical signal can be used to trigger the desired NAP, which otherwise would take a higher-power optical signal were the electric signal not applied. Some embodiments include an implanted nerve interface having a plurality of closely spaced electrodes placed transversely and/or longitudinally to the nerve and a plurality of optical emitters.

  • Patent number: 8152809
    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.

  • Publication number: 20110184306
    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.
