| 20110276110 | Power Circuitry for an Implantable Medical Device Using a DC-DC Converter - Improved power circuitry for charging a battery in an implantable medical device is disclosed. The improved power circuitry uses a DC-DC converter positioned between the rectifier and the battery in the implant to be charged, and operates to boost the voltage produced by the rectifier to a higher compliance voltage used to charge the battery. Because the rectifier can now produce a smaller DC voltage, the AC voltage preceding the rectifier (the coil voltage), can also be lessened. Lowering the coil voltage reduces the amount of heat generated by the coil, which reduces the overall heat generated by the implant during receipt of a magnetic charging field from an external charger during a charging session, which improves patient safety. Additionally, a reduced coil voltage means that the external charger can reduce the intensity of the magnetic charging field, which also reduces heat generated in the external charger during the charging session. | 11-10-2011 |

A sensor may receive a transceiver identification (ID) of an external transceiver conveyed from the external transceiver and determine whether the received transceiver ID is a new transceiver ID. If sensor determines the received transceiver ID to be a new transceiver ID, the sensor may store the received transceiver ID in a nonvolatile storage medium of the sensor and convey, using the sensor, measurement information stored in the nonvolatile storage medium to the external transceiver. | 04-09-2015 |
| 20150141777 | FLUORESCENCE-BASED SENSOR WITH MULTIPLE INDICATOR GRAFTS - A system including a sensor and a transceiver and configured to determine a concentration of an analyte in a medium of a living animal. The sensor may include first and second signal photodetectors and first and second reference photodetectors, which may each be covered by an associate filter. The first photodetector may receive light emitted from first and second grafts, respectively. The grafts may receive excitation light from one or more light sources. The transceiver may receive signals from the photodetectors of the sensor and may determine the analyte concentration based on the received signals. | 05-21-2015 |

| 20110077721 | IMPLANTABLE MICROSTIMULATORS AND METHODS FOR UNIDIRECTIONAL PROPAGATION OF ACTION POTENTIALS - Miniature implantable stimulators (i.e., microstimulators) are capable of producing unidirectionally propagating action potentials (UPAPs). The methods and configurations described may, for instance, arrest action potentials traveling in one direction, arrest action potentials of small diameters nerve fibers, arrest action potentials of large diameter nerve fibers. These methods and systems may limit side effects of bidirectional and/or less targeted stimulation. | 03-31-2011 |
| 20110152988 | CAVERNOUS NERVE STIMULATION VIA UNIDIRECTIONAL PROPAGATION OF ACTION POTENTIALS - Methods of using unidirectionally propagating action potentials (UPAPs) for cavernous nerve stimulation and for certain disorders are provided. Stimulators capable of creating such UPAPs include, but are not limited to, miniature implantable stimulators (i.e., microstimulators), possibly with programmably configurable electrodes. | 06-23-2011 |
