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.

A gastrointestinal stimulation devices including a random stimulation delivery mechanism(s), configured to provide stimuli to a bodily tissue in a vicinity of the stimulation capsule, the provided random stimuli being characterized by a stimulation parameter, and a control circuitry in communication with said physical stimulation delivery mechanism, and configured to set and alter the stimulation parameter non-systematically, thereby altering the characterization of the stimuli provided to the bodily tissue. The algorithm may be patient tailored, and may have a learning machinery which responds to data being received from the patient.

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.

A portable therapeutic device includes a portable body having a recessed central region and a raised outer peripheral edge surrounding the recessed central region and directly engaged with the recessed central region, a plurality of massage balls seated at the recessed central region and spaced inside a perimeter of the raised outer peripheral edge, a thermal-conductive element channeled inside the outer peripheral edge and spaced from the recessed central region, and a power source communicatively coupled to the massage balls and the thermal-conductive element.

A tip force monitoring and annunciation means which permits maintaining proper tip pressure during treatment of self-applied acoustic wave treatment for various parts of the user's body by an untrained user. The several embodiments of the disclosure employ designs, materials, and manufacturing methods which are inexpensive and consistent with current manufacturing practices. The functionality, size, cost, simplicity, ease of use, reliability and robustness of the proposed designs are all advantageous.

The foot-massaging device is a medical device adapted for use with a patient. The foot-massaging device is adapted for use with the left foot and the right foot of the patient. The foot-massaging device is adapted for use with the person lying in a prone position. The foot-massaging device massages, warms and provides therapeutic services to both the left foot and the right foot. The foot-massaging device comprises a chevron, a left foot apparatus, a right foot apparatus, and a control system. The left foot apparatus, the right foot apparatus, and the control system are mounted on the chevron. The left foot apparatus and the right foot apparatus massages, warms and provides electrical stimulation to the left foot and the right foot respectively.

A percussive adjusting instrument is provided which includes a percussive instrument head and a traversing arm that couples to the percussive instrument head. The percussive instrument head is movable with respect to the traversing arm. A vertical arm supports the traversing arm. The vertical arm also pivots the traversing arm and the percussive instrument head about an axis. A pivot assembly allows movement of the vertical arm and the percussive instrument head.

The disclosure discloses a sports massage device for relieving muscle soreness after exercising and an exercise apparatus, and relates to a technical field of fitness machine. The device includes a massage device and a mount. The massage device includes a housing, a rubber pad, a bulge, an iron cylinder, a second spring, a magnet and a cable. The housing is connected to the mount, an opening cover of the housing is provided with the rubber pad, the bulge is connected with an upper end of the rubber pad, the iron cylinder is connected within the housing, the iron cylinder, the second spring, the magnet and the rubber pad are sequentially connected, and the cable is used for connecting with an alternating current power supply and is wound around the iron cylinder, so that the iron cylinder generates magnetism to drive the magnet to vibrate when the cable is electrified.

A therapeutic vibration device includes a vibration generator, such as a tuning fork having an end, and a head or “boot” attached to the end of the generator and having a dimpled surface. The dimpled surface is sized and shaped to contact a patient to transmit vibrations to the patient for therapeutic benefits during treatment. The dimpled surface can be substantially spherically contoured and substantially smooth with dimples. The dimpled surface can have a dome or other convex shape.

An inner assembly and an outer assembly of a hypotrochoid apparatus with a spindle located inside the inner assembly where a spindle proximate end and a spindle distal end each employ at least one mechanical interface. An eccentric hub provides a central throughbore for receiving a spindle, where the spindle is rotatably engaged with the eccentric hub and the inner bore which enhances vibration when the spindle is rotating and the eccentric hub is engaged.
