The invention relates to apparatus and method for ultrasonically stimulating cartilage growth. The apparatus includes at least one ergonomically constructed ultrasonic transducer configured to cooperate with a placement module or strip for placement in proximity to an area where cartilage growth is desired. The apparatus also utilizes a portable, ergonomically constructed main operating unit constructed to fit within a pouch worn by the patient. In operation, at least one ultrasonic transducer positioned in proximity to an osteochondral site is excited for a predetermined period of time. To ensure that at least one ultrasonic transducer is properly positioned, and to insure compliance with a treatment protocol, a safety interlock is provided to prevent inadvertent excitation of the at least one ultrasonic transducer.

Method and apparatus for cartilage growth stimulation

A kit of elements including an ultrasonic generator, transducers with connecting cables, and a means for locating the transducers over areas of the body containing cartilage, is provided with the surgical instruments for post-surgical application to ultrasonically stimulate the cartilage growth, thus relieving the effects of surgical intervention.

Bony ingrowth adjacent a surface of a prosthetic device is provided by positioning an emitting surface of an ultrasonic applicator adjacent a skin location corresponding to an interface between bone tissue and an artificial prosthetic device located inside the body. Ultrasound is created and transmitted from the emitting surface into the body at the skin location toward at least a portion of the interface. The ultrasound is modulated to induce shear waves of acoustic energy within the bone adjacent the portion of the interface. The shear waves promote bony ingrowth at the portion of the interface.

Ultrasonic treatment for bony ingrowth

Ultrasonic transducer housing

This invention relates to apparatus and methods for providing and using a gel containment structure with an ultrasonic delivery system. The apparatus includes a special bladder, pad or other enclosure means for positioning adjacent the transmitting surface so that the coupling gel is retained adjacent the transmitting surface. The method for delivering ultrasonic energy includes enclosing coupling gel at the transmitting surface, positioning the enclosed coupling gel against the skin or other external location corresponding to the internal injury, and directing ultrasonic waves emitted at the transmitting surface through the enclosed conducting gel to the skin location corresponding to the internal injury.

Gel containment structure

The apparatus is used for therapeutically treating injuries using ultrasound. The apparatus includes an ergonomically constructed ultrasonic transducer treatment head module partially fabricated with a conductive plastic material. The apparatus also utilizes a portable, ergonomically constructed main operating unit constructed to fit within a pouch worn by the patient. In operation, the transducer treatment head module is positioned adjacent the area of the injury and excited for a predetermined period of time. To ensure that the transducer treatment head module is properly positioned, and to insure compliance with a treatment protocol, a safety interlock is provided to prevent inadvertent excitation of the transducer.

Apparatus for ultrasonic bone treatment

A transducer for non-invasive transcutaneous transmission of pulsed ultrahigh-frequency acoustic radiation, in body tissue and/or fluids adjacent a bone fracture is 'on target' when a fraction of the propagated energy within the longitudinal-response lobe of the transducer encounters a crack or other open feature of the fracture, where a gap or space exists between closely spaced fracture walls. The ultrahigh-frequency acoustic radiation sees this 'on target' feature as the entrance to a waveguide, whereby pulsed ultrahigh-frequency acoustic radiation is guided within the crack. When this acoustic radiation encounters a gap of at least a quarter wavelength (at the ultrahigh frequency), a standing wave condition establishes itself, with dissipation of the ultrahigh frequency and with demodulation to establish a therapeutically beneficial low-frequency acoustic condition, within the fracture, and acting where most needed, namely, on and between wall regions of adjacent fragments of the broken bone. Collagen, callus and cartilage development is accelerated, closing the gap in a matter of days, so that thereafter zone-flooding of shear waves from transducer radiation can be osteogenically operative upon both bone fragments of the fracture and on the collagen through which they are united at first tentatively and then increasingly more securely as treatment continues, from day to day, as with one or more single treatments of 20 minutes per day.
