A respiration-assistance apparatus or method can include or use a lifting element such as to cyclically push, pull, or lift, toward a superior direction of the subject, at least one subject region during an inhalation portion of a respiration cycle of the subject. A cyclical member can couple the lifting element to a fixed reference. Abdominal or ribcage compression can be provided. A multi-action or other cam can be used, such as together with a reciprocating element. Examples can be configured for use with a wheelchair, a bed, a vacuum or suction affixation element, a wearable garment, etc.

A therapy electrode apparatus for dispensing conductive gel to skin of a patient wearing a wearable defibrillator includes a therapy electrode, at least one reservoir comprising the conductive gel, and a gel deployment device comprising at least two reactive chemicals. The at least one reservoir is configured to release the conductive gel between the therapy electrode and a patient's skin prior to a delivery of one or more therapeutic shocks. The gel deployment device configured to, on receiving a treatment signal from a controller of the wearable defibrillator operably connected to the gel deployment device, cause the at least two reactive chemicals to come into contact to produce a pressurized fluid to release the conductive gel from the at least one reservoir between the therapy electrode and the patient's skin.

A skin regeneration therapy combining precise bioelectric signals, light, and biologics for skin treatment and regeneration. Precise bioelectric signals give clear instructions to the stimulated cell DNA/RNA to produce specific regenerative proteins on demand. Bioelectric signals give clear instructions to cell membranes on what to let in and what to let out and serve as an equivalent or surrogate of environmental stimuli to cause a cell action in response.

A method comprises generating, by an implantable stimulator, stimulation sessions at a duty cycle that is less than 0.05 and applying, by the implantable stimulator, the stimulation sessions to a patient. The duty cycle is a ratio of T3 to T4. Each stimulation session included in the stimulation sessions has a duration of T3 minutes and occurs at a rate of once every T4 minutes. The implantable stimulator is powered by a primary battery having an internal impedance greater than 5 ohms.

Semiconductor electroacupuncture needles are disclosed, as well methods of making and using the semiconductor electroacupuncture needles. A controller for controlling the characteristics of the voltage applied to the needles and/or the current flowing through the needles is described. In some embodiments, a portion of the electro acupuncture needle is insulated to control the position below the skin at which the current enters the patient. In some embodiments, an LED on the needle lights when current above a threshold value is passing through the needle and into the patient.

A method of treating hypertension includes an implantable stimulator generating stimulation sessions at a duty cycle that is less than 0.05 and applying the stimulation sessions by way of the central electrode and the annular electrode to a location associated with the hypertension and within a patient.

Devices, systems and methods are provided for treating a disease or disorder in a patient. The methods include positioning a surface of a housing in contact with an outer skin surface of the patient and applying sufficient energy to an energy transmitter within the housing via a power supply to generate an electrical impulse at or near a vagus nerve of the patient. The electrical impulse is sufficient to modulate fibers of the vagus nerve and treat the disease or disorder.

A patient treatment unit and method analyzes and treats pain in tissues by applying an electrical pulse train to the affected tissue. The impedance of the affected tissue is measured, and the measured impedance is correlated to a level of pain in the patient. The pulse train is further applied in response to the measured impedance to reduce the patient's pain. The patient treatment unit includes a probe stimulus generator that outputs the pulse train. The treatment unit also includes a pair of probes for contacting the patient's body and receiving the pulse train. The pulse has improved shaping based on isolation of high voltage from a low voltage control. The unit further includes a body impedance analysis circuit that senses voltage and current via the probes when the probes are contacting the patient and observe the impedance. A monitor is electrically coupled to the body impedance analysis circuit and provides an indication of the measured impedance indicative of the patient's level of pain in real-time.

Devices, systems and methods are provided for treating migraine headaches and other conditions by non-invasive electrical stimulation of nerves and other tissue. A hand-held device includes a housing with a controller having a signal generator, an electrode for delivering electrical signals, and a conductive surface configured as a return path for the electrical signals. In certain implementations, the electrode is repositionable with respect to the housing. The patient can self-apply the hand-held device by pressing it against areas in need of pain relief. The device may include a pressure-sensitive gating switch to control delivery of the stimulation therapy. In certain embodiments, the electrode is a rollerball electrode. The device may include a chamber for retaining and dispensing conductive gel to the therapy site. In certain approaches, the device includes an electrode support for coupling an electrical stimulation system to the head for hands-free electrical stimulation therapy.

A health-care device includes a work piece having an operating end and a opposite working end to perform a health-care work on a specific part or an acupoint of a body part of a user; a work body at its lower part the operating end is mounted so that a specific working relationship between the working end and the specific part or the acupoint is maintained; and a device positioning piece connected to the work body for maintaining a specific positional relationship between the working end and the specific part or the acupoint.
