    摘要: A system, device and method for removing occlusive material from a bodily lumen comprising a catheter with a distally mounted and fluid-fillable litho-cushion in operative connection with at least one forward-focusing reflector. The catheter comprises a lumen with an electrode pair housing disposed in watertight engagement with the lumen at or near the distal end of the lumen, the electrode pair housing comprising at least one electrode pair. The at least one electrode pair is in wired communication with a pulse generator, wherein the electrode pair is configured to generate an electrical arc between the electrodes of the electrode pair with subsequent generation of a shock wave. The shock wave is directed distally out of the catheter lumen and focused forward and distally away from the catheter lumen by the at least one reflector toward the targeted occlusive material.

    摘要: A high-intensity focused ultrasonic apparatus (10) and a control method are provided. An image of a region to be treated is obtained by means of an imaging device (100), a working assembly (300) and a target coordinate point in the region to be treated are located by means of an optical tracking device (200), so that a positioning device (400) can clamp the working assembly (300) to quickly and accurately move to a working position corresponding to the target coordinate point, thereby enabling the working assembly (300) to quickly and accurately release a high-intensity focused ultrasonic pulse to the target coordinate point, which improves not only the treatment accuracy but also the treatment efficiency of the high-intensity focused ultrasonic apparatus (10).

    摘要: A shockwave transducer (100)for a lithotripter includes a shockwave source (130) and a body with an exit aperture. The transducer is configured to generate a shockwave propagating from the body and through the exit aperture. The body comprises an at least one diffuser (210, 220), which engages into the shockwave propagating from the body. The at least one diffuser (210, 220) includes a material with a different propagation velocity than the propagation velocity of the surrounding medium.
