Patent number: 9498632Abstract: Receiver and digital demodulation circuitry for an external controller for communicating with an implantable medical device (IMD) is disclosed. A Digital Signal Processor (DSP) is used to sample received analog data transmitted from the IMD at a lower rate than would otherwise be required for the frequency components in the transmitted data by the Nyquist sampling criteria. To allow for this reduced sampling rate, the incoming data is shifted to a lower intermediate frequency using a switching circuit. The switching circuit receives a clock signal, which is preferably but not necessarily the same clock signal used by the DSP to sample the data. The switching circuit multiplies the received data with the clock signal to produce lower intermediate frequencies, which can then be adequately sampled at the DSP at the reduced sampling rate per the Nyquist sampling criteria.Type: GrantFiled: July 15, 2013Date of Patent: November 22, 2016Assignee: Boston Scientific Neuromodulation CorporationInventors: Thomas W.

Patent number: 9427591Abstract: A base station for passively recharging a battery in an implant without patient involvement is disclosed. The base station can be hand held or may comprise equipment configured to be placed at a fixed location, such as under a bed, on or next to a wall, etc. The base station can generate electric and magnetic fields (E-field and B-field) that couple with an antenna and a receiving coil within the implant to generate a charging current for charging the implant's battery. No handling or manipulation on part of the patient is necessary; the implant battery is passively charged whenever the patient is within range of either the magnetic or electric charging fields generated by base station. Charging using the B-field occurs when the IPG is at a relatively short distance from the base station, while charging using the E-field occurs at longer distances.Type: GrantFiled: November 10, 2015Date of Patent: August 30, 2016Assignee: Boston Scientific Neuromodulation CorporationInventors: Joey Chen, Robert Ozawa, Joonho Hyun, Vasily Dronov

Patent number: 9403021Abstract: A driving circuit useful in a magnetic inductive coupling wireless communication system is disclosed. The circuit includes an inductor (coil) and capacitor in series selectively coupled to a power source such as a rechargeable battery. The LC circuit is made to resonate in accordance with a Frequency Shift Keying or other protocol. Such resonance produces a voltage across the inductor. This voltage is used to create a first voltage either by tapping into the coil, or by providing a transformer. The first voltage is coupled to the rechargeable battery by a diode. When the circuit resonates, and when the first voltage exceeds the voltage of the power source, the diode turns on, thus shunting excess current back to recharge the rechargeable battery. By use of this circuit, energy is conserved. Additionally, oscillations can be quickly dampened so as to allow the circuit to transmit at high data rates.Type: GrantFiled: October 14, 2015Date of Patent: August 2, 2016Assignee: Boston Scientific Neuromdulation CorporationInventor: Vasily Dronov

Patent number: 9265957Abstract: An implantable medical device and external base station system are disclosed. The external base station can provide a passive electric field to power the implant, or to charge its battery. The base station may also power or charge using magnetic fields under certain circumstances. The Implantable medical device may comprise an implantable neurostimulator having a number of electrode leads extending from its body. One or more of the electrode leads can comprise the antenna for receiving the electric field from the base station, and resonance in that antenna can be rectified to provide the power for recharging the battery. Although the E-field provided by the base station does not provide as much power for recharging as does other traditional charging techniques, it can occur passively and over longer distances to allow the patent's implant to be recharged when in relative proximity to the base station.Type: GrantFiled: June 23, 2011Date of Patent: February 23, 2016Assignee: Boston Scientific Neuromodulation CorporationInventors: Joey Chen, Robert Ozawa, Joonho Hyun, Vasily Dronov

Publication number: 20160030756Abstract: A driving circuit useful in a magnetic inductive coupling wireless communication system is disclosed. The circuit includes an inductor (coil; L) and capacitor (C) in series selectively coupled to a power source such as a rechargeable battery. The LC circuit is made to resonate in accordance with a Frequency Shift Keying (FSK) or other protocol. Such resonance produces a voltage across the inductor. This voltage is used to create a first voltage either by tapping into the coil, or by providing a transformer. The first voltage is coupled to the rechargeable battery by a diode. When the circuit resonates, and when the first voltage exceeds the voltage of the power source, the diode turns on, thus shunting excess current back to recharge the rechargeable battery.

Patent number: 9070507Abstract: Communication and charging circuitry for an implantable medical device is described having a single coil for receiving charging energy and for data telemetry. The circuitry removes from the AC side of the circuit a tuning capacitor and switch traditionally used to tune the tank circuitry to different frequencies for telemetry and charging. As such, the tank circuitry is simplified and contains no switchable components. A switch is serially connected to the storage capacitor on the DC side of the circuit. During telemetry, the switch is opened, thus disconnecting the storage capacitor from the tank circuit, and alleviating concerns that this capacitor will couple to the tank circuit and interfere with telemetry operations. During charging, the switch is closed, which allows the storage capacitor to couple to the tank circuitry through the rectifier during some portions of the tank circuitry's resonance.Type: GrantFiled: February 26, 2014Date of Patent: June 30, 2015Assignee: Boston Scientific Neuromodulation CorporationInventors: Vasily Dronov, Jordi Parramon, Robert Ozawa, Md.

Publication number: 20140025139Abstract: Receiver and demodulation circuitry for an external controller for an implantable medical device is disclosed. The circuitry comprises two high Quality-factor band pass filters (BFPs) connected in series. Each BFP is tuned to a different center frequency, such that these center frequencies are outside the band of frequencies transmitted form the IMD. The resulting frequency response is suitably wide to receive the band without attenuation, but sharply rejects noise outside of the band. The resulting filtered signal is input to a comparator to produce a square wave of the filtered signal, which maintains the frequencies of the received signal and is suitable for input to a digital input of a microcontroller in the external controller. Demodulation of the square wave occurs in the microcontroller, and involves assessing the time between transitions in the square wave. These transmission timings are compared to expected transition times for the logic states in the transmitted data.Type: ApplicationFiled: May 23, 2013Publication date: January 23, 2014Applicant: Boston Scientific Neuromodulation CorporationInventors: Thomas W.

Publication number: 20130110203Abstract: Combination charging and telemetry circuit for use within an implantable medical device uses a single coil for both charging and telemetry that is controlled via the use of an opto-switch. One or more capacitors are used to tune the coil to different frequencies for receiving power from an external device and for the telemetry of information to and from an external device. The opto-switch is coupled to the resonant circuit, but because its input is electrically decoupled from its output, it easy to control.Type: ApplicationFiled: September 12, 2012Publication date: May 2, 2013Applicant: Boston Scientific Neuromodulation CorporationInventors: Vasily Dronov, Jordi Parramon, Daniel Aghassian, Md.

Publication number: 20120101551Abstract: An improved external controller useable with an implantable medical device is disclosed. The external controller comprises a front cover, a back cover, and a sub-assembly. The sub-assembly comprises an electronics chassis on which non-surface mount components, such as the telemetry coils and the battery, can be affixed.
