Implantable devices and/or sensors can be wirelessly powered by controlling and propagating electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological, physiological, chemical attributes of the blood, tissue, and other patient parameters. The propagating electromagnetic waves can be generated with sub-wavelength structures configured to manipulate evanescent fields outside of tissue to generate the propagating waves inside the tissue. Methods of use are also described.

Myofascial-releasing devices and methods related thereto are described. The myofascial-releasing device includes: (i) a gripping portion designed for gripping by user, which includes: (a) a spine designed to receive hand and fingers in a gripping configuration; (b) a thumb stabilizing element protruding from the spine along a curved, protruding path that has defined therein a first web space of palm locking contour, which is designed to stabilize a user's first web space of palm and a surrounding region; and (c) finger stabilizing element protruding from the spine; and (ii) an extending portion that extends from a second end of the gripping portion and that terminates at an elongated end such that during use of the myofascial-releasing instrument, the elongated end is configured to be driven into muscle containing fascia, and the first end is opposite to the second end of the gripping portion.

In some embodiments, a kit may include systems allowing for clearing a biological airway. The kit may include an inner wearable system worn, during use, on a torso of a subject. The kit may include a plurality of engines which when activated apply an oscillation force to at least one treatment area of the subject. At least one of the plurality of engines may be releasably couplable to the inner wearable system. The oscillation force may be applied to at least one of the treatment areas of the subject such that the oscillation force mobilizes, during use, at least some secretions in an airway within the subject at least adjacent the treatment area. The kit may include an outer wearable system worn, during use, on a torso of a subject which when activated, adjusts the oscillation force. The kit may include one or more batteries and/or a control unit.

A massage device for a seat, in particular for a vehicle seat, is disclosed. The massage device comprises at least one air cushion, wherein the at least one air cushion has an air inlet so as to allow individual filling thereof with air via an air supply system,

wherein a vibration generating device is arranged between the air supply system and the air cushion and is in fluid communication with the air cushion so as to apply pressure vibrations to the air cushion.

In addition, the a seat comprising the massage device is also disclosed.

A vibration device includes a device body, and intraoral device, and an extraoral device. The vibration device can include a motor that vibrates the intraoral and extraoral attachments. The vibration device can include a power source configured to selectively activate the motor. The power source can be recharged from a recharging base. The vibration device can include a lighting assembly powered from the power source. The intraoral and extraoral attachments alternately and removably engage the device body. The intraoral attachment can include a brush tray that can include a plurality of bristles. The extraoral attachment can include a massage head. The vibration device can include a body connector member configured to alternately and removably connect the extraoral and the intraoral attachments. The intraoral and extraoral attachments can include a connector shaft configured to directly engage the motor to receive vibration.

A percussive massage device includes an enclosure having a cylindrical bore that extends along a longitudinal axis. A motor has a rotatable shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot, which is offset from the central axis of the shaft. A reciprocation linkage has a first end coupled to the pivot of the crank. A piston has a first end coupled to a second end of the reciprocation linkage. The piston is constrained to move within a cylinder along the longitudinal axis of the cylindrical bore. An applicator head has a first end coupled to a second end of the piston and has a second end exposed outside the cylindrical bore for application to a person receiving treatment. A motor controller measures current applied to the motor and displays a pressure indicator responsive to the measured current.

The present disclosure relates to a device for generating shock waves that includes an interchangeable applicator head for generating shock waves for treatment of human or animal bodies, which applicator head includes a reflection or focusing mechanism, two electrode tips for producing a spark gap, and a membrane, which together with the reflection or focusing mechanism encloses a fluid medium that is designed to generate a plasma when a voltage between 1 kV and 30 kV is applied. According to the disclosure, the applicator head is electrically and mechanically connected to a hand-held apparatus in a detachable manner.

A vibration module for applying vibrational tractions to a wearer's skin is presented. Use of the vibration module in headphones is illustrated for providing tactile sensations of low frequency for music, for massage, and for electrical recording and stimulation of the wearer. Damped, planar, electromagnetically-actuated vibration modules of the moving magnet type are presented in theory and reduced to practice, and shown to provide a substantially uniform frequency response over the range 40-200 Hz with a minimum of unwanted audio.
