20100145414 | BIOMIMETIC NEUROSTIMULATION DEVICE - A neuromimetic device includes a feedforward pathway and a feedback pathway. The device operates in parallel with a suspect neural region, coupled between regions afferent and efferent to the suspect region. The device can be trained to mimic the suspect region while the region is still considered functional; and then replace the region once the region is considered dysfunctional. The device may be particularly useful in treating neuromotor issues such as Parkinson's disease. | 06-10-2010 |
20100179620 | SYSTEM AND METHOD FOR PROMOTING DIURESIS AND NATRIURESIS BY THE APPLICATION OF ELECTRIC FIELDS TO THE KIDNEY - A system and method of applying an electric field to the kidney of a subject can reduce renal salt and water retention through the process of electrophoresis. The system includes a first and a second electrode, at least of which is implantably associated with the kidney. The electric field can be controlled to affect the removal of a first constituent (e.g. sodium) from the kidney while the level of a second constituent (e.g. potassium) is maintained within normal physiological range. | 07-15-2010 |
20100331923 | SYMMETRICAL OUTPUT NEUROSTIMULATION DEVICE - A method and system of providing therapy to a patient using electrodes implanted adjacent tissue. The method comprises regulating a first voltage at an anode of the electrodes relative to the tissue, regulating a second voltage at a cathode of the electrodes relative to the tissue, and conveying electrical stimulation energy between the anode at the first voltage and the cathode at the second voltage, thereby stimulating the neural tissue. The system comprises a grounding electrode configured for being placed in contact with the tissue, electrical terminals configured for being respectively coupled to the electrodes, a first regulator configured for being electrically coupled between an anode of the electrodes and the grounding electrode, a second regulator configured for being electrically coupled between an anode of the electrodes and the grounding electrode, and control circuitry configured for controlling the regulators to convey electrical stimulation energy between the anode and cathode. | 12-30-2010 |
20110077722 | NEUROSTIMULATOR - Methods and devices of stimulating nerves are disclosed. In one embodiment adapted for stimulating excitable tissue, the invention includes drive circuitry ( | 03-31-2011 |
20120095531 | System and Method for Wireless Power Transfer in Implantable Medical Devices - A system and method for energy transfer between a transmitting unit and a receiving unit, the transmitting unit having a transmitting antenna circuit having a first resonant frequency and a high quality factor. | 04-19-2012 |
20130096655 | SHORT DURATION PRE-PULSING TO REDUCE STIMULATION-EVOKED SIDE-EFFECTS - A method and neurostimulation system of providing therapy to a patient is provided. At least one electrode is place in contact with tissue of a patient. A sub-threshold, hyperpolarizing, conditioning pre-pulse (e.g., an anodic pulse) is conveyed from the electrode(s) to render a first region of the tissue (e.g., dorsal root fibers) less excitable to stimulation, and a depolarizing stimulation pulse (e.g., a cathodic pulse) is conveyed from the electrode(s) to stimulate a second different region of the tissue (e.g., dorsal column fibers). The conditioning pre-pulse has a relatively short duration (e.g., less than 200 μs). | 04-18-2013 |

20160144171 | SYSTEMS AND METHODS FOR GENERATING BIPHASIC WAVEFORMS - This present disclosure describes systems that use a constant current source to generate biphasic waveforms. In one example, a positive, constant current is generated from a single constant current source, and then applied to either end of an output workload in an alternating manner, such as at a predefined frequency. In another example, a constant current source is used to generate a positive phase, and a constant current sink along with a voltage source are used to generate a negative phase. An alternating adoption of these two phases, therefore, gives rise to the application of a biphasic waveform on an output workload. | 05-26-2016 |
