Patent number: 9358399Abstract: An external charger for a battery in an implantable medical device and charging techniques are disclosed. Simulation data is used to model the power dissipation of the charging circuitry in the implant at varying levels of implant power. A power dissipation limit constrains the charging circuitry from producing an inordinate amount of heat to the tissue surrounding the implant, and duty cycles of a charging field are determined so as not to exceed that limit. A maximum simulated average battery current determines the optimal (i.e., quickest) battery charging current, and at least an optimal value for a parameter indicative of that current is determined and stored in the external charger. During charging, the actual value for that parameter is determined, and the intensity and/or duty cycle of the charging field are adjusted to ensure that charging is as fast as possible, while still not exceeding the power dissipation limit.Type: GrantFiled: May 30, 2014Date of Patent: June 7, 2016Assignee: Boston Scientific Neuromodulation CorporationInventors: Rafael Carbunaru, Jordi Parramon, Robert Ozawa, Jess Shi, Joey Chen, Md.

Patent number: 9339648Abstract: Methods and systems are disclosed for determining the timing of stimulation applied using a medical device. In embodiments, the medical device filters a received signal to obtain a plurality of band-pass filtered signals, each corresponding to one or more stimulation channels.

Next, the medical device determines the stimulation timing (i.e., the pulse times) for the corresponding stimulation channel based on the timing of a particular phase (e.g., a peak, a minimum, etc.) of the envelope. A pulse amplitude for the stimulation channel may then be determined, and stimulation applied using the determined amplitude and pulse time.Type: GrantFiled: January 28, 2014Date of Patent: May 17, 2016Assignee: Cochlear LimitedInventor: Zachary Mark Smith

Patent number: 9317729Abstract: RFID-based sensors, RFID readers and software sense a changed condition. In one embodiment, an RFID-based sensor includes a base that may be placed at a location where a condition may change. The sensor includes an RFID tag that is coupled to the base. The sensor also includes a detector that can be electrically coupled to the RFID tag. If the condition changes, an electrical property of the detector also changes, impacting an operation of the RFID tag. The impacted operation can be detected by an RFID reader/interrogator so as to provide a notification. An advantage over the prior art is that the condition change can be sensed wirelessly over a domain that can be laborious or hazardous to access otherwise. Moreover, RFID based sensors can be made by modifying common RFID tags.Type: GrantFiled: October 28, 2013Date of Patent: April 19, 2016Assignee: WEST AFFUM HOLDINGS CORP.Inventors: Blaine Krusor, Isabelle Banville, Joseph Leo Sullivan, David Peter Finch, Daniel Ralph Piha, Laura Marie Gustavson, Kenneth Frederick Cowan, Richard C.

Patent number: 9308368Abstract: A visual prosthesis must convey luminance information across a range of brightness levels to accurately represent a visual scene. Thus, the brightness of phosphenes produced by individual electrodes should scale appropriately with luminance, and the same luminance should produce equivalently bright phosphenes across the entire electrode array. Given that the function relating current to brightness varies across electrodes, it is necessary to develop a fitting procedure that will permit brightness to be equated across an entire array. A visual prosthesis that generates stimuli by performing a brightness fitting that normalizes brightness across electrodes is described.Type: GrantFiled: March 6, 2014Date of Patent: April 12, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Scott H Greenwald, Matthew J McMahon, Ione Fine

Patent number: 9302102Abstract: An electro-therapeutic stimulator provides an output signal having a first controllable main pulse periodic-exponential signal and a second background pulse periodic-exponential signal. The main pulse signal is controllable, preferably to a digital numerical value of 1 to 500 pulses per second, to a digital, numerical value of duty cycle, and to a digital numerical value of balance. The signal is produced using a class D amplifier and with a transformer optimized for the background pulse (such as at 10 kHz) rather than for the main pulse. The electro-therapeutic stimulator includes a counter which forces purchasing of durations of signal time for ongoing use of the stimulator, and a challenge code procedure for facilitating additional time purchases.Type: GrantFiled: October 5, 2010Date of Patent: April 5, 2016Assignee: ARP Manufacturing LLCInventors: Gary Edward Thomas, Denis E.
