NEUROSTIMULATION WITH ENHANCED PASSIVE RECOVERY

Abstract: a system may include a neurostimulator and a programmer. the neurostimulator may have a plurality of electrodes, and may be configured to deliver neurostimulation by delivering neurostimulation pulses of a first polarity to a neural target using at least one stimulation electrode from the plurality of electrodes and passively recovering charge using a first number of one or more passive electrodes from the plurality of electrodes. the programmer may have a user interface configured to receive a user input for changing a number of passive electrodes used to passively recover charge from the first number to a second number. the programmer may be configured to control the neurostimulator to passively recover charge using the second number of passive electrodes. some examples may include fractionalization to control the contribution of each passive electrode used to recover charge. a variable impedance may be used to control a relative charge recovery current.
