Patent
Highland Instruments, Inc. | Date: 2015-08-07

An apparatus for generating focused currents in biological tissue is provided. The apparatus comprises an electric source capable of generating an electric field across a region of tissue and means for altering the permittivity of the tissue relative to the electric field, whereby a displacement current is generated. The means for altering the permittivity may be a chemical source, optical source, mechanical source, thermal source, or electromagnetic source.

DESCRIPTION provided by applicant This proposal includes trade secrets and other proprietary or confidential information of Highland Instruments and is being provided for use by the National Institutes of Health NIH for the sole purpose of evaluating this SBIR proposal No other rights are conferred This proposal and the trade secrets and other proprietary or confidential information contained herein shall further not be disclosed in whole or in parts outside of NIH without Highland Instrumentandapos s permission This restriction does not limit the NIHandapos s right to use information contained in the data if it is obtained from another source without restriction This legend applies to the entire proposal including but not limited to the Abstract Introduction Specific Aims Research Plan all components Commercialization Plan and Human Subjectandapos s Sections of this proposal Abstract OA of the knee is a leading cause of chronic pain and disability Conventional treatments do not directly address the fact that pain sensation is processed in the brain and mechanical joint dysfunction can be worsened by chronic pain induced changes in the brainandapos s motor control centers Non Invasive Brain Stimulation NIBS has been successfully applied for the treatment of chronic pain in some disease states where treatment induced changes in brain activity revert maladaptive plasticity associated with the perception sensation of chronic pain However the most common NIBS methods Transcranial Magnetic Stimulation TMS and Transcranial Direct Current Stimulation tDCS fail to show consistent clinical benefit on par with that of the conventional pain treatments and are not commonly used for OA therapy It has been postulated that limitations in these techniquesandapos focality penetration and targeting control limit their therapeutc efficacy Electrosonic Stimulation ESStim tm is an improved NIBS modality that overcomes the limitations of other technologies by combining independently controlled electromagnetic and ultrasonic fields to focus and boost stimulation currents via tuned electromechanical coupling in neural tissue This proposal is focused on evaluating whether our noninvasive ESStim system can effectively treat chronic OA pain and in turn improve knee biomechanical function and patient quality of life QOL First in Phase I to assess the feasibilit of the proposed work we will follow OA patients after giving a constant fixed dose of ESStim for min day on consecutive days SHAM ESStim ESStim We will assess a battery of safety pain biomechanical knee function and QOL measures in the patients evaluated over the treatment period and for at least six weeks following the last treatment session Next in Phase II we will follow OA patients after giving a constant fixed dose of stimulation for days min day over a two week period Patients will randomly be assigned to of stimulation conditions ESStim tDCS transcranial ultrasound TUS or SHAM ESStim We will evaluate these patients with the battery of pain biomechanical QOL and safety measures which were validated in the Phase I studies and compare the efficacy of the tested interventions for at least eight weeks following the last treatment session Furthermore we will test whether the ESStim pain suppression can be guided by the baseline disease state To test this we will build and evaluate multivariate linear and generalized linear regression models to predict the clinical outcomes and identify best responders Overall we hypothesize that the proposed experiments computational studies and technology development will allow us to test the effectiveness of ESStim in OA patients The work will serve as the basis for a future large scale multicenter study and further the commercialization of ESStim OA therapy PUBLIC HEALTH RELEVANCE Osteoarthritis OA of the knee is a major cause of chronic pain and a leading cause of disability Alternative therapies such as Non Invasive Brain Stimulation NIBS have been successfully applied for the treatment of chronic pain in other diseases whereby treatment induced changes in brain activity revert maladaptive plasticity associated with the perception sensation of chronic pain This study analyzes NIBS treatments for chronic pain in OA patients


Patent
Highland Instruments, Inc. | Date: 2014-10-22

An apparatus for interfacing between tissues being stimulated is provided. The apparatus includes an electric source capable of generating an applied electric field across a region of tissue and/or a means for altering at least one electromagnetic characteristic of the region of tissue relative to the applied electric field and an interface component, such interface component creating an interface between the region of tissue and the applied electric field or the means for altering at least one electromagnetic characteristic of the region of tissue.
