Patent number: 10966754Abstract: An apparatus for delivering an electrical microstimulator having a microstimulator body comprises a handle having a handle body. An elongate delivery rod includes a delivery sleeve and a stretching shaft, with one of the delivery sleeve and the stretching shaft configured for reciprocal movement with respect to the handle body, and the other extending longitudinally from, and stationary relative to, the handle body. The delivery sleeve selectively engages a fixation aperture of a microstimulator docking feature having a fixation base and a fixation member, concurrent with the stretching shaft engaging a proximal end of the microstimulator body. Longitudinal motion of the delivery sleeve with respect to the stretching shaft causes longitudinal motion of the fixation base to responsively move the fixation member between substantially linear and substantially coiled states. A method of delivering an electrical microstimulator to a target implant site of a patient's body is also provided.Type: GrantFiled: February 25, 2019Date of Patent: April 6, 2021Assignee: AVATION MEDICAL, INC.Inventors: Benjamin A.

Patent number: 8446212Abstract: Disclosed are systems and methods which provide voltage conversion in increments less than integer multiples of a power supply (e.g., battery) voltage. A representative embodiment provides power supply voltage multipliers in a binary ladder distribution to provide a desired number of output voltage steps using a relatively uncomplicated circuit design. By using different sources in various combinations and/or by “stacking” different sources in various ways, the voltage multiplier circuit may be used to provide desired voltages. In order to minimize the number of components used in a voltage converter of an embodiment, a capacitive voltage converter circuit uses one or more storage capacitors in place of pump capacitors in a voltage generation cycle. Also, certain embodiments do not operate to generate an output voltage until the time that voltage is needed.Type: GrantFiled: May 14, 2012Date of Patent: May 21, 2013Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Benjamin A Tranchina, John H Erickson, Anthony J Varrichio

Patent number: 8095221Abstract: To avoid charge accumulation on capacitive connections to implanted electrodes during delivery of stimulation pulses, stimulation pulses are followed by active discharge pulses having opposite polarity of the stimulation pulses. The active discharge pulses preferably have at least one pulse attribute magnitude (e.g., duration, voltage, and/or current) different than a corresponding stimulation pulse and are preferably programmable. Approximately the same total net current flow is delivered during active discharge pulses as during the stimulation pulses, but in the opposite direction and optionally at a lower amplitude. In addition, by reducing the driving voltage and a variable load within the electrical path for delivery of the pulses, power dissipation during active discharge is preferably reduced.Type: GrantFiled: May 27, 2008Date of Patent: January 10, 2012Assignee: Advanced Neuromodulation Systems, Inc.Inventors: Anthony J Varrichio, Benjamin A Tranchina
