Abstract: What is presented is an ultrasonic waveguide for the transmission of ultrasonic vibrations that establishes a plurality of node and anti-node positions that are each along the ultrasonic waveguide's central axis. The ultrasonic waveguide comprises a waveguide tube, which has both a proximal end and a distal end; a waveguide fitting, which has both a threaded end and a impact surface; and a spring, shock-pulsing mass, and stop. Both the spring and shock-pulsing mass are each positioned on the waveguide tube. Whereas, the stop is positioned on the waveguide tube and it is adapted to non-fixedly engage the spring and shock-pulsing mass. The impact surface of the waveguide fitting is located at an anti-node position, which is along the central axis of the ultra-sonic waveguide when its installed within ultrasonic transducer while in operation.

Abstract: An ultrasonic medical device can include a transducer, a coupling system, and a waveguide. The coupling system can be configured to attach and adequately torque the waveguide to the transducer for use in a medical procedure. The coupling system can be configured to detach the inner probe from the transducer upon completion of the medical procedure.

Abstract: A percutaneous surgical instrument for de-bulking calculi or drilling bone includes an actuator for generating vibrations at ultrasonic frequencies and a horn coupled to said actuator for amplifying the actuator vibration. A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and under said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

Abstract: The present invention relates to a device with an ultrasonic-based probe for drilling and coring. The invention uses ultrasonic and subsonic vibrations produced by a frequency compensation coupler or free mass to produce the hammering action of a partially disengaged probe, with a relatively low axial force required. The invention can also be fitted with irrigation and aspiration capabilities. The invention can furthermore be furnished with a body sensor-feedback apparatus, which provides feedback to the operator as to the optimal frequency and power use of the generator. One embodiment of the invention also has a cooling mechanism to keep the drill or coring apparatus at an optimum temperature.

Abstract: A transducer assembly and method for coupling ultrasonic energy to a body for thrombolysis of vascular thrombi is provided. The assembly includes a catalytic transducer for transmitting ultrasound into a medical target transcutaneously. The catalytic transducer includes a front mass having structure which optimizes the transmission of ultrasound into the body. A reservoir for containing a cooling conductive medium between the front mass and the body surface is provided, and is contained within the housing. In addition, the catalytic transducer includes an irrigation manifold, disposed through a center of the front mass, for directing the media into the reservoir generally along a perimeter thereof. The front mass includes an apex for accumulating expelled gasses. A sloped surface of the front mass functions to direct expelled gasses toward the apex and through an outlet provided by the irrigation manifold.

Abstract: A method and apparatus for ultrasonically cleaning the interior of a flexible, elongate, tubular medical instrument, such as an endoscope, laparoscope, or the like involves the generation of both longitudinal and transverse ultrasonic waves in a fluid medium within the interior channel or lumen of the instrument. The ultrasonic waves are generated within the instrument by a flexible wire resonator coupled to and responsive to an ultrasonic transducer and generator.

Abstract: The disc recording cutter head is carried on the inner end of an arm which is pivoted intermediate its ends. A counterbalance weight on the outer end of the arm exactly counterbalances the cutter head. A direct current torque motor mounted on the pivot axis applies cutting force to the cutting stylus. Additional features optionally include damping of arm motion by arm position feedback to the torque motor and control of the cutting force as a function of stereo program material.
