Abstract: 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.

Abstract: 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.

Abstract: 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.
