<p>In accordance with one embodiment, a vibratory transducer has an armature suspended in a magnetic field. The armature has a plurality of electrical conductive paths to provide electrical current flow in said armature to react with said magnetic field and cause movement in the armature controlled by variation in the electrical current flow. A contact surface is secured to the armature, with a surface area for frictionally coupling to a corresponding surface area of a patient for example. Movement of the vibratory transducer induces movement in the patient, and the transducer can produce movement in the contact surface in at least two dimensions simultaneously. In one embodiment the contact surface is flat, while in alternative embodiments the contact surface is incorporated in a toroidal structure so as to surround part of the patient. Medical application can include treatment of bone fractures, oedema, and in elastography, amongst other applications.</p> |
