Sample and Hold Circuitry for Monitoring Voltages in an Implantable Neurostimulator

Номер: US20120092031A1
Автор: Emanuel Feldman, Jess W. Shi, Jordi Parramon
Принадлежит: Boston Scientific Neuromodulation Corp

Sample and hold circuitry for monitoring electrodes and other voltages in an implantable neurostimulator is disclosed. The sample and hold circuitry in one embodiment contains multiplexers to selected appropriate voltages and to pass them to two storage capacitors during two different measurement phases. The capacitors are in a later stage serially connected to add the two voltages stored on the capacitors, and voltages present at the top and bottom of the serial connection are then input to a differential amplifier to compute their difference. The sample and hold circuitry is particularly useful in calculating the resistance between two electrodes, and is further particularly useful when resistance is measured using a biphasic pulse. The sample and hold circuitry is flexible, and can be used to measure other voltages of interest during biphasic or monophasic pulsing.

Direct memory access (dma) controlled stimulation

Номер: US20120158096A1
Автор: Neil S. Sherman
Принадлежит: Spinal Modulation LLC

An implantable stimulation system (e.g., an implantable neurostimulation system (INS)) comprises memory including a first table and a second table. The first table stores blocks of stimulation event data corresponding to stimulation events that are to be performed during a period of time (e.g., a 0.5 sec. or 1 sec. period of time). The second table stores blocks of next stimulation event time data corresponding to the period of time. The implantable stimulation system also includes a direct memory access (DMA) controller including a first DMA channel and a second DMA channel. The first DMA channel selectively transfers one of the blocks stimulation event data from the first table to one or more registers that are used to control stimulation events. The second DMA channel selectively transfers one of the blocks of next stimulation event time data from the second table to a timer that is used to control timing associated with the stimulation events. In this manner, the DMA controller is able to control stimulation.

OPERATION AND ESTIMATION OF OUTPUT VOLTAGE OF WIRELESS STIMULATORS

Принадлежит: EBR Systems, Inc.

A controller-transmitter transmits acoustic energy through the body to an implanted acoustic receiver-stimulator. The receiver-stimulator converts the acoustic energy into electrical energy and delivers the electrical energy to tissue using an electrode assembly. The receiver-stimulator limits the output voltage delivered to the tissue to a predetermined maximum output voltage. In the presence of interfering acoustic energy sources output voltages are thereby limited prior to being delivered to the tissue. Furthermore, the controller-transmitter estimates the output voltage that is delivered to the tissue by the implanted receiver-stimulator. The controller-transmitter measures a query spike voltage resulting from the electrical energy delivered to the tissue by the receiver-stimulator, and computes a ratio of the predetermined maximum output voltage and a maximum query spike voltage. The maximum query spike voltage is computed by detecting a query spike voltage plateau. Based on this ratio, the controller-transmitter uses a measured query spike voltage to estimate the output voltage delivered by the receiver-stimulator to tissue. 1.
