A patch for a therapeutic electrical stimulation device includes a shoe connected to the first side of the patch, the shoe including a body extending in a longitudinal direction from a first end to a second end, and having first and second surfaces, the first end of the shoe defining at least two ports, and the first surface of the shoe defining a connection member. The patch also includes at least one conductor positioned in the ports of the first end of the shoe. The shoe is configured for sliding insertion into a receptacle defined by a controller so that the conductor is connected to the controller to deliver electrical current from the controller, through the conductor, and to the electrodes, and the connection member is at least partially captured by a detent defined by the controller in the receptacle to retain the shoe within the receptacle.

This application discloses an improved approach for delivering Tumor Treating Fields (TTFields) at a therapeutically effective strength to the infratentorial regions of the brain. A first set of electrode elements is positioned on top of the head and a second set of electrode elements is positioned on the back of the neck. Third and fourth sets of electrode elements are positioned on the lower back right and the lower back left portions of the scalp, respectively. Applying an AC voltage between the first and second sets of electrode elements generates a generally vertical field in the infratentorial regions of the brain; and applying an AC voltage between the third and fourth sets of electrode elements generates a generally horizontal field in those regions.

Methods and apparatus are provided for multi-vessel neuromodulation, e.g., via a pulsed electric field. Such multi-vessel neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, the multi-vessel neuromodulation is applied to neural fibers that contribute to renal function. Such multi-vessel neuromodulation optionally may be performed bilaterally.

Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

A wearable haptic navigation system for obscured visibility environments, the wearable haptic navigation system including: a wearable haptic component, in one alternative a body covering suite; and a mapping data collector and processor in communication with the wearable haptic component; wherein the mapping data collector and processor collects data related to a path traversed by a user of the wearable haptic navigation system and generates at least one proprioception suggestion signal to the wearable haptic component providing the user with a suggested safe egress path and/or a suggested safe body position.

A noninvasive/minimally invasive neuromodulation system and method for providing therapy to a target neural tissue of a patient. In one arrangement, an example method comprises applying at least two input waveforms to respective pairs of electrodes affixed on the patient's skin or subcutaneously disposed relative to the target neural tissue, wherein the frequencies of the input waveforms are configured such that they combine, when simultaneously applied, to generate a beat waveform having a beat frequency due to interference. The beat waveform is causative of a transcutaneous/subcutaneous temporal interference (T/STI) electric field generated in the patient body, the T/STI electric field including an interference region at least partially overlapping the target neural tissue of the patient, wherein the beat frequency is of a value operative to impart a therapeutic effect to the target neural tissue.

An example method for electrical stimulation of a subject includes creating multiple circuits using implantable electrodes positioned in the subject, transmitting a signal of a first frequency through a first circuit of the multiple circuits and the first circuit generates a first electrical field, and transmitting a signal of a second frequency through a second circuit of the multiple circuits and the second circuit generates a second electrical field. The implantable electrodes are positioned in a substantially linear configuration along a same axis such that the first electrical field and the second electrical field are in an axial bias configuration, and the first electrical field and the second electrical field interfere with each other at an area of overlap to produce a beat signal.
