|20150282725||Method and System for Controlling Electrical Conditions of Tissue II - A method for controlling electrical conditions of tissue in relation to a current stimulus. A first current produced by a first current source is delivered to the tissue via a current injection electrode. A second current drawn by a second current source is extracted from the tissue via a current extraction electrode. The second current source is matched with the first current source so as to balance the first current and the second current. A ground electrode which is proximal to the current injection electrode and the current extraction electrode is grounded, to provide a ground path for any mismatch current between the first current and second current. A response of the tissue to the current stimulus is measured via at least one measurement electrode.||10-08-2015|
|20140243931||METHOD AND APPARATUS FOR APPLICATION OF A NEURAL STIMULUS - A method of applying a neural stimulus with an implanted electrode array involves applying a sequence of stimuli configured to yield a therapeutic effect while suppressing psychophysical side effects. The stimuli sequence is configured such that a first stimulus recruits a portion of the fibre population, and a second stimulus is delivered within the refractory period following the first stimulus and the second stimulus being configured to recruit a further portion of the fibre population. Using an electrode array and suitable relative timing of the stimuli, ascending or descending volleys of evoked responses can be selectively synchronised or desynchronised to give directional control over responses evoked.||08-28-2014|
|20140236257||METHOD AND APPARATUS FOR CONTROLLING A NEURAL STIMULUS - An implantable device applies and controls a neural stimulus. The device has a plurality of electrodes, and a stimulus source for providing a stimulus to be delivered from the electrodes to a neural pathway in order to evoke an action potential on the neural pathway, such as the spinal cord. A control unit controls application of a neural stimulus as defined by a set of parameter values and measures via measurement circuitry an evoked neural compound action potential response. The control unit determines from the measured evoked response a feedback variable, and compares it to a therapy map. The therapy map defines a therapeutic relationship of control variable to feedback variable. One or more of the stimulus parameter values are altered to effect the required change in the control variable. This process is performed iteratively to improve alignment of the feedback variable with the therapy map over time.||08-21-2014|
|20140236042||METHOD AND APPARATUS FOR MEASUREMENT OF NEURAL RESPONSE - A method for estimating conduction velocity of a neural response. Measurements of the neural response are obtained from at least two electrodes which are at distinct locations along a neural pathway. A delay between the time of arrival of the neural response at each respective electrode is determined from the measurements. From the delay, and from knowledge of electrode spacing, a conduction velocity of the neural response is estimated.||08-21-2014|
|20140194772||METHOD AND APPARATUS FOR MEASUREMENT OF NEURAL RESPONSE - A device for measuring a neural response evoked by a stimulus. First and second sense electrodes are positioned at distinct locations along a neural pathway. A neural stimulus is applied and first and second recordings of a neural response evoked by the stimulus are obtained from the respective sense electrodes. The first recording and the second recording are compared to determine propagation properties of the evoked neural response.||07-10-2014|
|20130289683||DISTRIBUTED IMPLANT SYSTEMS - A distributed implantable neurostimulation system. One or more electrode arrays each have at least one electrode configured to be positioned at a desired implant location within the body. An implantable control unit is configured to selectively direct stimulus and/or telemetry instructions and power to each electrode of each array. A shared bus extends to each of the plurality of electrode arrays, the bus interconnecting each array with the implantable control unit. There is at least one electrode cell associated with each electrode array. The electrode cell obtains electrical power and command signals from the shared bus, and controls operation of each electrode associated with that electrode cell. The bus is connected to the control unit and/or the electrode cell by docking contacts of the bus to form electrical contact with contacts of the control unit and/or electrode cell.||10-31-2013|
