Patent ID: 7628744

Claim:
An instrument for training and rehabilitating a patient's pelvic muscles comprising a probe configured for insertion into a pelvic cavity and including at least one sensor for dynamically sensing a force applied to the probe by contraction of the pelvic muscles, vibrator apparatus disposed in the probe for imparting mechanical vibrations against the pelvic muscles, and a control circuit coupled to the sensor and the vibrator apparatus for selectively operating the training instrument in a passive, reaction mode in which passive tactile feedback signals are produced with co-generation of biofeedback signals proportional to pelvic muscle contractions, and in an active, vibrating mode in which vibration therapy is applied directly to internal pelvic musculature; and in a combination of both modes simultaneously; said sensor includes a variable impedance element for exhibiting a change in electrical impedance in response to pressure forces applied to the probe; and said control circuit includes an electronic circuit module enclosed within the probe and electrically coupled to the variable impedance element for transmitting wireless feedback signals in response to pelvic contraction forces applied to the probe.
