A medical patch having a multi-piece bottom liner including a central liner sequentially removable independently of two outer perimeter liners. The multi-piece liner covering two adhesives of different peel force. Removal of the central liner exposes a first temporary/repositionable adhesive. Once properly positioned, the outer perimeter liners are removed to expose a second stronger adhesive. A foam cushioning layer is disposed beneath and extends beyond a footprint of every printed circuit board to prevent skin irritation. The medical patch may be designed specifically for stimulation of the sacral (S3 foramen) spinal nerve without the use of a separate mechanical placement tool or assistance by another.

Transdermal medical patch

A placement device for a medical patch includes an alignment guide having a shaft with a first end having a first anatomical alignment marker and a second end having a second anatomical alignment marker, a swinging gate both pivotally and rotationally coupled with the first end of the shaft for selectively pivoting the gate toward and away from the shaft and rotating the gate between opposite sides of the shaft, whereby the gate has first and second major faces and a first opening extending through the gate between the first and second major faces. The placement device includes a spacer for selectively adjusting spacing between the gate and the first end of the shaft, and a flexible diaphragm having a flexible dome disposed within the first gate opening. At least one magnet is located in the center of the flexible dome for holding the medical patch within the flexible dome.

Placement devices that enable patients to accurately position medical patches at target locations and methods therefor

A method and associated stimulation device for ensuring firing of an action potential in an intended physiological target activated by a stimulus pulse generated by an electrode of a non-invasive surface based stimulation device irrespective of skin-to-electrode impedance by: (i) increasing internal impedance of the stimulation device so as to widen a Chronaxie time period thereby ensuring firing of the action potential of the intended physiological target irrespective of the skin-to-electrode impedance; and/or (ii) generating a stimulation waveform that optimizes a non-zero average current (e.g., non-zero slope of the envelope of the stimulation waveform) during preferably substantially the entire current decay of the stimulus pulse.

Optimizing the stimulus current in a surface based stimulation device

A method for stimulating a predetermined body part such as a nerve using a stimulation device including an external non-implantable transmitting device powered by a power source and generating an electrical waveform signal. A surface electrode applies the generated electrical waveform signal transcutaneously. An implantable piezoelectric element receives the applied electrical waveform signal generated transcutaneously and, in turn, causes mechanical deformation resulting in mechanical vibration of the implantable piezoelectric element sufficient to stimulate the predetermined body part. The electrical waveform signal may be either a high frequency continuous waveform or high frequency burst packets.

Piezoelectric stimulation device

A selective nerve stimulation patch includes a substrate having a top surface and a bottom surface, integrated components overlying the top surface of the substrate and being electrically interconnected with one another for generating at least one nerve stimulating signal, electrodes integrated into the substrate and exposed at the bottom surface thereof for applying the at least one nerve stimulating signal to a target nerve, a waterproof, breathable cover overlying the substrate and the integrated components, and a support flange surrounding the substrate and coupling the cover and the substrate together. The support flange has a top surface that slopes downwardly toward an outer perimeter thereof, and at least a portion of the cover conforms to the sloping top surface of the support flange. In one embodiment, the patch generates a high frequency waveform with properties such as amplitude, frequency and the like chosen so as to overcome tissue impedance and the stimulation threshold of the target nerve. The modulated waveform is the waveform obtained by modulating the carrier waveform by a pulse envelope.

Nerve stimulation patches and methods for stimulating selected nerves

A system for stimulating a nerve or nerves in a patient includes an electrode patch having an array of equally spaced concentric electrodes each having a central cathode and a concentrically surrounding anode. The electrode array patch is used to determine the location of the nerve or nerves to be stimulated by electrical pulses. Once the location of the nerve is determined, a concentric electrode patch having a central cathode and a concentrically surrounding anode is positioned at the optimal location on the patient's skin to effect neurostimulation. The concentric electrode patch may be removably affixed to the patient's skin by adhesive or magnets.

Electrode patch and method for neurostimulation

A nerve stimulation device includes a first waveform generator adapted to generate a first waveform having a first frequency capable of stimulating nerves within a dermatome, a second waveform generator adapted to generate a first carrier waveform having a second frequency capable of passing through tissue of a mammal, and a third waveform generator adapted to generate a second carrier waveform having a third frequency different than the second frequency and being capable of passing through the tissue of the mammal. The device includes a modulator electrically coupled to the first, second and third waveform generators and adapted to modulate the first waveform, the first carrier waveform, and the second carrier waveform to generate a modulated signal package capable of stimulating the nerves at different depths within the dermatome. The device also has an electrode electrically coupled to the modulator for applying the modulated waveform to the dermatomic region.

Dermatome stimulation devices and methods

An implantable urodynamic system includes an implantable first device deployable in a patient's bladder, an implantable second device deployable in a patient's vaginal canal, and a data acquisition and analysis module or processing unit external to the body of the patient. The first device includes a magnet and an inductive coil, and the second device includes a magnet, an inductive coil and a battery. When deployed in the patient's body, attraction between the magnets maintains the two devices in close proximity to one another to effect an inductive coupling between the coils so that the first device may be powered by the battery of the second device. The urodynamic system is intended to facilitate measurement, collection, and wireless transmission of real-time, or near real-time, data (bladder pressure, abdominal pressure, and temperature) from an ambulatory patient. This data is of value in diagnosing a number of abnormal bladder conditions, such as infection, overactive bladder, bladder spasms, and the like.

System and method for urodynamic evaluation utilizing micro electro-mechanical system technology

A method and system for optimizing stimulation therapy of an external stimulating device. The stimulating signal for stimulation of a target nerve is produced using the external stimulating device. A magnetic field is induced in an implanted transmitting coil disposed proximate the target nerve when the action potential is fired along an axon of the target nerve. In turn, a feedback signal is generated in a receiving coil associated with the external stimulating device based on whether the target nerve fires an action potential. Stimulating signal parameters of the stimulating signal are adjusted based on the feedback signal.
