20210361942 | SACRAL NERVE STIMULATION - In some examples, a method including determining a chronaxie of evoked threshold motor responses from electrical stimulation delivered to a sacral nerve of a patient; and delivering, based on the determined chronaxie, electrical stimulation therapy, configured to treat a patient condition, to the sacral nerve having a pulse width at or near the identified chronaxie, wherein the delivered electrical stimulation is configured to inhibit contraction of at least one a bladder or bowel of the patient. | 2021-11-25 |
20210361943 | SYSTEMS, DEVICES AND METHODS FOR NEUROSTIMULATION - Systems, devices, and methods for neurostimulation via vestibular stimulation are described. One example is a device for administering thermal stimulation to an ear canal of a subject. The device may include an earpiece configured to be at least partially insertable into the ear canal of the subject; a thermoelectric device thermally coupled to the earpiece and configured to heat and/or cool the earpiece to thereby heat and/or cool the ear canal of the subject; and a controller configured to administer a selected treatment plan including administering a caloric vestibular stimulation (CVS) stimulus to the ear canal of the subject in a condition-treatment effective amount during a first treatment interval. The treatment plan may be effective to produce a durable improvement in at least one symptom of the condition for a time of at least 1 week following cessation of the administering. | 2021-11-25 |
20210361944 | PATIENT-CUSTOMIZED ELECTRODE ARRAYS BASED ON PATIENT-SPECIFIC COCHLEAR INFORMATION, AND DESIGNING/SELECTING METHODS AND APPLICATIONS OF SAME - A method for designing a patient-customized EA or selecting an existing EA that fits the patient best includes segmenting shapes of SOIs of the cochlea in a pre-operative CT image using a shape model; defining a 3D curve of interest within the shape model of the SOIs as a sequence of points-; automatically transforming the defined 3D curve to the pre-operative CT image so as to obtain a structure curve in the cochlea; determining a length and curvatures of the structure curve at the sequence of points; and designing a patient-customized EA or selecting an existing EA based on the determined length and curvatures of the structure curve such that after the EA shape model, which estimates the resting state shape of the EA, is rigidly registered to the structure curve in the cochlea, the EA shape model has a registration error smaller than a preset value. | 2021-11-25 |
20210361945 | SYSTEM AND METHOD FOR RATE MODULATED CARDIAC THERAPY UTILIZING A TEMPERATURE SENSOR - Described herein are implantable medical systems, and methods for use therewith, that provide a temperature based rate response for a patient within which the implantable medical system is implanted. Such a method can include sensing a blood temperature signal indicative of a core body temperature of the patient, and producing a relative temperature signal based on the blood temperature signal. The method can further include producing a moving baseline temperature signal based on the relative temperature signal, producing a proportional response signal based on the relative temperature signal and the moving baseline temperature signal, and producing a sensor indicated rate response signal based on the proportional response signal and a base rate. The sensor indicated rate response signal can also be based on a dip response signal and/or a slope response signal. Additionally, a pacing rate is controlled based on the sensor indicated rate response signal. | 2021-11-25 |
20210361946 | OPTIMIZATION OF APPLICATION OF CURRENT - An excitation unit is configured to induce action potentials by applying an excitatory current to a nerve. A blocking unit is configured to block the induced action potentials from propagating along the nerve by applying a blocking current to the nerve. A sensor unit is configured to detect the induced action potentials in the nerve, and to responsively provide a sensor signal that conveys information about the detected induced action potentials. Circuitry is configured (i) to drive the excitation unit to apply the excitatory current, (ii) to drive the blocking unit to apply the blocking current, (iii) while driving the blocking unit to apply the blocking current, to drive the sensor unit to detect the induced action potentials and provide the sensor signal, (iv) to receive the sensor signal, and (v) in response to the sensor signal, to alter a parameter of the blocking current. | 2021-11-25 |
20210361947 | SYSTEMS AND METHODS FOR SELECTING STIMULATION PARAMETERS BASED ON STIMULATION TARGET REGION, EFFECTS, OR SIDE EFFECTS - A system or method for identifying sets of stimulation parameters can include receiving at least one image of a region of a patient; registering the at least one image with an anatomical or physiological atlas that identifies different anatomical or physiological structures; identifying a desired stimulation region using the at least one image; comparing the desired stimulation region with each of a plurality of predetermined estimated stimulation regions, where each of the estimated stimulation regions is a calculated estimate of a stimulation volume for a corresponding set of electrical stimulation parameters; selecting one of the predetermined estimated stimulation regions based on the comparing; and providing the corresponding set of electrical stimulation parameters for the selected one of the predetermined estimated stimulation regions to a user or an electrical stimulation device. Other systems or methods use functional maps or subregions of a region of synchronous neural activity to identify stimulation parameters. | 2021-11-25 |
