摘要： A hollow member is made from a material such as titanium with properties of vibrating longitudinally. The interior surface of the hollow member is preferably quite smooth. At least one member is disposed on the hollow member and is provided with properties of vibrating longitudinally at an ultrasonic frequency when energized. Preferably a plurality of such vibratory members are disposed around the periphery of the hollow members. The vibratory members may be crystals. The vibratory members are preferably disposed in a socket in the hollow member so that the vibratory members are flush with the hollow member. A hollow catheter made from a pliant material such as a silicone rubber is disposed on the hollow member and the vibratory members and is preferably provided with a substantially smooth inner periphery and a substantially smooth outer periphery along its length. The forward end of the catheter preferably covers the forward end of the hollow member and preferably has a blunt disposition. The hollow member, the vibratory members and the catheter are disposed in an artery and are movable along the artery to emulsify plaque on the interior wall of the artery without damaging the interior wall of the artery. The emulsified plaque is removed as by a vacuum through the hollow member and the catheter.

摘要： The present disclosure deals with ultrasonically selectively dissolving solid and semi-solid unwanted materials, such as vitreous gels, membranes, cataracts and similar materials in ophthalmic operation applications, for example, by radiating from a physically small source, high-frequency, preferably pulsed, acoustic waves, while positioning the material to be selectively locally dissolved by such waves at a selected region sometimes in contact with or near-contact or within a short distance from the source of the order of a millimeter or so, at which the propagated acoustic wave energy can effect such phenomena as, for example, localized cytolysis of the material at the selected region thereof substantially normal to the wavefront of the radiated acoustic wave region, and without substantial damage to the portions of the material external to said selected region, and with adjustment to obviate any substantial temperature rise at the material.

摘要： The present application provides a preoperative detection method and a postoperative detection method for neuromapping, comprising releasing an electrical signal towards the renal artery blood vessel on one lateral side of the body of the patient by the electrode element; monitoring a heart rate by an electrocardiogram monitoring module, and monitoring a blood pressure change in said another renal artery blood vessel on the other lateral side of the body of the patient by the pressure sensor, and determining a nerve activity degree of the patient by judging whether the heart rate and the blood pressure change reach certain thresholds and making determinations in relation to the nerve activity degree so as to screen out the patients with an overactive sympathetic nerve, and a surgical effect of a denervation surgery can also be evaluated before or after the surgery, and can be used to determine whether to perform an ultrasonic ablation again.

摘要： The invention provides a system for treating an occlusion within a body lumen. The system may comprise an insulated outer sheath; an elongated conductive tube, wherein the insulated outer sheath is circumferentially mounted around the elongated conductive tube; and an insulated wire having a helically coiled portion at a distal end of the insulated wire. The coiled portion includes an exposed distal tip, and a distal portion of the elongated conductive tube is circumferentially mounted around the distal coiled portion of the insulated wire. When a voltage is applied across the insulated wire and the elongated conductive tube, a current is configured to flow from the exposed distal tip of the insulated wire to the elongated conductive tube to generate a plurality of cavitation bubbles. In an alternate embodiment, an elongated central electrode is used in place of the conductive tube.

摘要： Embodiments are directed to electro-hydraulically actuated lithotripters and methods for fragmenting stones using such lithotripters. In an embodiment, a lithotripter apparatus for fragmenting at least one stone in a body is disclosed. The lithotripter apparatus includes a chamber configured to contain an electro-conductive fluid, which includes a proximal end wall and a distal end wall spaced from the proximal end wall. A chisel is coupled to the chamber and located at least proximate to the distal end wall. A proximal electrode is located at least partially in the chamber. A distal electrode is located at least partially in the chamber and spaced from the proximal electrode. Responsive to an effective voltage applied between the proximal and distal electrodes, the proximal and distal electrodes are configured to electrically discharge into the electro-conductive fluid to generate shock waves in the chamber that accelerate the chisel toward the at least one stone.

摘要： Described here are devices and methods for forming shock waves. The devices may comprise an axially extending elongate member. A first electrode pair may comprise a first electrode and a second electrode. The first electrode pair may be provided on the elongate member and positioned within a conductive fluid. A controller may be coupled to the first electrode pair. The controller may be configured to deliver a series of individual pulses to the first electrode pair, where each pulse creates a shock wave. The controller may cause current to flow through the electrode pair in a first direction for some of the pulses in the series and in a second direction opposite the first direction for the remaining pulses in the series.

摘要： Disclosed herein shock wave catheters comprising one or more shock wave electrodes for cracking calcifications located within blood vessels. In some variations, a shock wave catheter has first and second shock wave electrodes each circumferentially disposed over the outer surface of the catheter. In certain variations, the first electrode has a recess and the second electrode has a protrusion that is received by the recess and a spark gap is located along the separation between the recess and the protrusion. The second electrode can also have a recess that receives a protrusion from a third shock wave electrode, where the separation between the second and third electrodes along the separation between the recess and the protrusion forms a second spark gap. A shock wave can be initiated across these spark gaps when a voltage is applied over the electrodes.
