An implantable neurostimulator for delivering one or more stimulation pulses to a target region within a patient's body. The implantable neurostimulator including a housing and an energy storage feature. There is also a lead coupled to the hermetic housing and a plurality of electrodes located proximate to a distal end of the lead. The neurostimulator includes stimulation circuitry that includes an adjustable resistance element. A voltage of the electric signal derived from the energy storage feature and a resistance of the adjustable resistance element are both adjusted based on a measurement of a value indicative of a tissue impedance of the target region to provide a desired value of a stimulation current for the one or more stimulation pulses.

Low energy implantable devices and methods of use

A medical device for tissue ablation may include a catheter shaft, an expandable member disposed on or coupled to the catheter shaft, and a plurality of elongate electrode assemblies each constructed as a flexible circuit. The expandable member may be configured to shift between an unexpanded configuration and an expanded configuration. The plurality of electrode assemblies may be disposed on an outer surface of the expandable member. Each of the plurality of electrode assemblies may include a temperature sensor aligned with two or more electrodes.

Alternative placement of thermal sensors on bipolar electrode

Devices, systems, and methods for coupling with an implantable neurostimulator for delivering one or more electrical pulses to a target region within a patient's body are disclosed herein. A device, such as a charger, can include: a power source for storing electrical energy; a resonant circuit that can have a plurality of selectable natural frequencies; a driver coupled to the power source and the resonant circuit; and a processor coupled to the resonant circuit to control the natural frequency of the resonant circuit. The processor can determine the natural frequency of the implantable neurostimulator, and can control the resonant circuit according to the determined natural frequency of the neurostimulator.

Methods and systems for frequency adjustment to optimize charging of implantable neurostimulator

A training system for a neurostimulation system that may be used to simulate a neurostimulator programming session and/or lead placement. The system may include a training device that may be coupled to a neurostimulator programmer and may include an interface to allow user interaction and/or display information relevant to the stimulation. The trainer device may include circuitry for simulating a neurostimulator such as an IPG or EPG, and may include circuitry for simulating impedance associated with lead placement.

Trainer for a neurostimulator programmer and associated methods of use with a neurostimulation system

An implantable pulse generator that includes a current source/sink generator is disclosed herein. The current source/sink generator includes a current drive differential amplifier. The current driver differential amplifier is configured to selectively source current to, or sink current from a target tissue. The current drive differential amplifier includes an inverting input and a non-inverting input. One of the inputs of the current drive differential amplifier is connected to a virtual ground, and the other is connected to a current command. A stimulation controller can supply a voltage to the other of the inputs of the current drive differential amplifier to select either current sourcing or current sinking.

Implantable nerve stimulator having internal electronics without ASIC and methods of use

Systems and methods for improved power transmission are disclosed herein. The system can include an implantable neurostimulator for delivering the one or more electrical pulses to a patient's body. The implantable neurostimulator can include a hermetic housing made of a biocompatible material, an energy storage feature for powering the implantable neurostimulator, a receiving coil assembly including an elongate wire winding wound around a first ferritic core, and control circuitry for controlling recharging of the energy storage feature. The system can include a charging device for wirelessly delivering energy to the implantable neurostimulator. The charging device can include a sending coil assembly including a planar wire winding coupled to a surface of a second ferritic core.

A tampon disposal device includes a tubular stiffener, and a membrane conforming to the stiffener with an opening on one end and an enclosure opposite the opening. The membrane is folded inside the stiffener into a first layer attached to the stiffener; and second and third layers that form a lip surrounding the stiffener near a stiffener rim. The second layer folds over the rim, reversing direction to become the third layer lip portion. The third layer continues inside the stiffener. A weak adhesive attaches the lip to the outside stiffener. Another adhesive attaches the first layer to the second layer inside the stiffener. When a hand grasps a tampon siring with the membrane and pulls on the string, the first adhesive allows the lip to separate and be pulled into the stiffener together with the tampon. Pushing inwardly on the stiffener seals the tampon inside the membrane.
