Abstract

The present disclosure generally relates to systems and methods for a stimulation system. Various aspects of the present disclosure relate generally to the treatment of epilepsy, depression and/or other conditions in a subject using a nerve stimulator and, more particularly, to an effective and quicker titration method for selection of stimulation parameters of the nerve stimulator using biological markers that indicate potential therapeutic effects. Some aspects of the present disclosure may utilize a pupillometry sensor synchronized with the VNS stimulation system to compare pupil size of a subject with stimulation on and off and for obtaining filtered pupil response measurements after stimulating each electrode while modulating the stimulation parameters. Thus, aspects of the present disclosure allow for quicker titration of programmable stimulation parameters (e.g., stimulation pulse amplitude) to levels that cause a therapeutic result in a matter of minutes instead of months as compared to related VNS systems.

Abstract

Pressure sensors having ring-tensioned membranes are disclosed. A tensioning ring is bonded to a membrane in a manner that results in the tensioning ring applying a tensile force to the membrane, flattening the membrane and reducing or eliminating defects that may have occurred during production. The membrane is bonded to the sensor housing at a point outside the tensioning ring, preventing the process of bonding the membrane to the housing from introducing defects into the tensioned portion of the membrane. A dielectric may be introduced into the gap between the membrane and the counter electrode in a capacitive pressure sensor, resulting in an improved dynamic range.

Abstract

A multiple output current stimulator circuit with fast turn on time is described. At least one pair of input side and output side transistors is arranged in a current mirror connected to a supply transistor by cascode coupling. The output side transistor supplies stimulation current to an electrode in contact with tissue. An operational amplifier connected to a reference voltage and to the output side transistor drives the supply transistor to maintain the voltage at the output side transistor equal to the reference voltage. The at least one pair of transistors includes multiple pairs of transistors whose output side transistors drive respective electrodes with stimulation currents. The stimulator determines the initiation and duration of stimulation current pulses supplied to each electrode. At circuit activation, large currents are generated which discharge capacitances in the output side transistors causing rapid output side transistor turn on.

Abstract

A medical system and method of communicating between a telemetry controller and medical devices is provided. Coupling coefficients between a primary coil of the telemetry controller and secondary coils of the medical devices differ from each other. A primary carrier signal is applied to the primary coil, thereby respectively inducing secondary carrier signals on the secondary coils. An amplitude of the secondary carrier signal is measured on each of the secondary coils. The envelope of each secondary carrier signal is modulated in accordance with data, thereby inducing modulation of the envelope of the primary carrier signal for the implanted medical devices. The secondary carrier signal envelopes are modulated based on the measured amplitudes of the respective secondary carrier signals.

Abstract

Biocompatible stiffness enhanced pliable electrically conductive filaments configured for contact with living tissue and electrical communication with such tissue. The pliability of the filaments allows the distal end of the filaments to remain at the original site of penetration into the tissue despite the movement of the tissue relative to their surrounding environment. To temporarily stiffen the filaments, a soluble stiffness enhancing coating is disposed over the filaments. The coating may be in the form of a liquid which dries to a solid state after being applied to the filaments and renders the filaments sufficiently rigid such that under appropriate force, the filaments are capable of penetrating into dense tissue. Once in place, the stiffness enhancing coating dissolves due to contact with body fluids, the filaments, in the absence of such a coating, return to their initial pliability.
