Abstract: 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.

Abstract: 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.

Abstract: An apparatus and method for mounting an ultrasound transducer head module. The apparatus includes an insert having an axial bore therein and a plurality of tabs extending radially therefrom. A spacer is provided and configured to fit within a void in a cast. The spacer has a hole therein to insertably receive the insert. An ultrasound transmission-enhancing medium is positioned within the hole in the spacer and adjacent a treatment location. The ultrasound treatment head module is then positioned within the insert and means for biasing it toward the ultrasound transmission-enhancing medium is provided. A strap may be provided to secure the apparatus adjacent a body portion to be treated, with or without the existence of a cast.
