  • Publication number: 20170281950
    Abstract: Circuitry useable to protect and reliably charge a rechargeable battery, even from a zero-volt state, is disclosed, and is particularly useful when employed in an implantable medical device. The circuit includes two charging paths, a first path for trickle charging the battery at a relatively low current when the battery voltage is below a threshold, and a second path for charging the battery at relatively higher currents that the battery voltage is above a certain threshold. A passive diode is used in the first trickle-charging path which allows trickle charging even when the battery voltage is too low for reliable gating, while a gateable switch (preferably a PMOS transistor) is used in the second higher-current charging path when the voltage is higher and the switch can therefore be gated more reliably. A second diode between the two paths ensures no leakage to the substrate through the gateable switch during trickle charging.

  • Publication number: 20170216598
    Abstract: A method of providing therapy to a patient using a plurality of electrodes is provided. The electrodes are located adjacent a target neural tissue region having a first nerve fiber of a relatively small diameter and a second nerve fiber of a relatively large diameter. The method comprises sourcing electrical current from a local anode into the target neural tissue region. The method further comprises therapeutically sinking a first portion of the electrical current from the target neural tissue region into a local cathode. The method further comprises sinking a second portion of the electrical current into a cathode remote from the target neural tissue region. The ratio of the sourced electrical current over the first sunk electrical current portion has a value that allows the first nerve fiber to be recruited by the electrical current while preventing the second nerve fiber from being recruited by the electrical current.

  • Publication number: 20170120056
    Abstract: An implantable pulse generator includes a current steering capability that allows a clinician or patient to quickly determine a desired electrode stimulation pattern, including which electrodes of a group of electrodes within an electrode array should receive a stimulation current, including the amplitude, width and pulse repetition rate of such current. Movement of the selected group of electrodes is facilitated through the use of remotely generated directional signals, generated by a pointing device, such as a joystick. As movement of the selected group of electrodes occurs, current redistribution amongst the various electrode contacts takes place. The redistribution of stimulus amplitudes utilizes re-normalization of amplitudes so that the perceptual level remains fairly constant. This prevents the resulting paresthesia from falling below the perceptual threshold or above the comfort threshold.

The toggling sequence is representative of a digital data stream according to a digital wireless communication protocol. The subcutaneous medical device identifies, based on the detected toggling sequence and in accordance with the digital wireless communication protocol, a multi-bit command encoded within the digital data stream represented by the toggling sequence. The subcutaneous medical device further performs, in response to the identifying of the multi-bit command, an action associated with the multi-bit command. Corresponding methods and a corresponding external controller are also disclosed.
