Abstract:
Devices and methods for removal of calculus (including for example, kidney stones) are disclosed. In an embodiment, a device for removal of kidney stones includes a substantially sealable pouch that can be inserted into the kidney for capturing a kidney stone. The pouch is also designed to permit fragmentation of the kidney stone inside the pouch, while preventing kidney stone fragments from escaping from the pouch. As a result, the likelihood of dispersing stone fragments during fragmentation of a large stone is greatly lessened.
Abstract:
A system (10) is attachable to a surface of a tissue (18) of a patient for applying pressure pulses to the tissue (18). The system (10) includes a shockwave transducer (12) that has a shockwave generating portion (14) and a solid transducer interface (16) arranged to directly contact a tissue (18) of a patient. The shockwave generating portion (14) includes an electrical-to-shockwave energy converter operable to generate shockwaves. The transducer interface (16) includes an electrically safe and bio- compatible material arranged to transmit the shockwaves from the shockwave generating portion (14) to the tissue (18).
Abstract:
A shock-wave applicator for Shock-wave medical treatment instruments, in particular for dermatology or aesthetic medicine, comprises a suction devices made of a substantially tubular member placed at the front end of the shockwave applicator which forms together with the applicator itself a suction chamber connected to a suction pump for creating a vacuum in the suction chamber. A suction aperture of the tubular member touches the biological tissue to be treated which is sucked in the suction chamber and gets in touch with the shock-wave transmission membrane of the applicator. The pressure core produced by the applicator remains within the suction chamber and it only affects the soft tissues sucked in the chamber. A strong reduction of pain associated to this kind of therapies is obtained together with a reduction of the noisiness of the shock-wave applicator.

Abstract:
An system and method for applying acoustic pressure waves including a pad coupled with a shock wave applicator coupler. The pad includes a bioactive substance in which shock waves facilitate absorption of the bioactive substance into a target area, such as skin and wounds.
Abstract:
An extrusion apparatus for ultrasonic therapy of intestinal tract, includes an extrusion component and an acoustic-permeable component (2). One end of said acoustic-permeable component (2) is connected to a cingulum (1), and the other end is connected to an adhesive tap (3). The acoustic-permeable component (2) is bound to the human abdomen via the linkage of the cingulum (1) and the adhesive tap (3). The extrusion component employs a hydraulic pressure system (4).
Abstract:
Ein medizinisches Gerät zur Behandlung des menschlichen oder tierischen Körpers mit mechanischen Druck- oder Stoßwellen weist eine Vorrichtung zur Erzeugung der Druck- oder Stoßwellen auf, die zumindest ein Applikatorteil (18; 64; 94) aufweist, das zur Erzeugung der Druck- oder Stoßwellen auf einer proximalen Seite mit Stößen beaufschlagbar ist, und das auf einer distalen Seite die Druck- oder Stoßwellen in den Körper einkoppelt. Das Gerät (10; 60; 90) ist zusätzlich zur extrakorporalen Erzeugung zumindest eines weiteren physiologischen Wirkungsparameters und Einkopplung desselben in den Körper ausgebildet, der aus der Gruppe ausgewählt ist, die elektrischen Strom, elektromagnetische Wellen, insbesondere Licht, Ultraschall, und/oder eine weitere mechanische Wirkung enthält.
Abstract:
A first ultrasonic medical instrument includes an ultrasound transducer, a medical ultrasonic blade, and a tube adapted to contain a liquid. A first tube end is adapted to have the liquid proximate the first tube end, when the tube contains the liquid, be ultrasonically vibrated to generate an ultrasonically-vibrating energy wave. The ultrasonic blade is acoustically connected to the liquid proximate a second tube end, when the tube contains the liquid. A second ultrasonic medical instrument includes a heat pulse initiator, a medical ultrasonic blade, and a tube adapted to contain a liquid. The heat pulse initiator is adapted to output heat pulses having an ultrasonic pulse frequency. A first tube end is adapted to receive the heat pulses outputted by the heat pulse initiator, wherein the heat pulses have an energy sufficient to create an ultrasonically-vibrating energy wave in the liquid, when the tube contains the liquid.
Abstract:
A storage unit holds representations of sensor signals which would be received by a set (30) of ultrasonic transducers (32) from an ultrasonic impulse emitter positioned at each of plural points (P) in the frame of reference of the transducer set. An impulse may be applied at a particular point by using the representation associated with that point to generate an actuation signal corresponding to a time-reversed version of the sensor signal. Impulses may be applied in a pattern (150) by using those representations associated with points in the pattern to generate actuation signals and applying those signals to the transducer set. By placing the transducer set in a known spatial relationship to the a body structure such as heart, an ablation pattern may be formed in a desired relationship to the body structure, such as around the ostium of a pulmonary vein.
