Abstract: An ophthalmic light instrument includes a plug (1) and a light guide (7) for guiding light (10) to a surgical site in the eye. The plug (1) is configured to be magnetically attractable or attractive and can be positioned and connected releasably with respect to a light source in such a way, that coupling of the light (10) into the light instrument takes place at the focal point (14) of the light source (12). An ophthalmic illumination system includes such a light instrument and a socket of the light source. The socket of the light source (4) is configured to be magnetically attractable or attractive and can be positioned and connected releasably with respect to the light source in such a way, that coupling of the light (10) into the light instrument takes place at the focal point (14) of the light source (12).

Abstract: A medical device is described, which comprises a basic device and at least one replaceable component connected therewith, said component having an item belonging to the device that is subjected to high wear or consumption. A storage medium is connected to the component, which stores component-specific data and can be read independently of the basic device.

Abstract: A device for producing electrical discharges in an aqueous medium which comprises a first electrode and a second electrode comprised of a superalloy having a cobalt content of greater than 8% by weight or optionally a nickel content of greater than 8% by weight. A high electrical voltage is applied to the electrodes to produce a voltage discharge into the medium that creates a pressure wave in the medium. The electrodes of the device exhibit high thermal shock resistance during discharge thereby reducing tip burnout.

Abstract: A medical system for treatment with focussed acoustic waves having a locating device, a therapy device, a patient positioning device, power supply devices for these devices. The complete system is installed in an integrated manner and adjusted on a common equipment carrier. The carrier frame corresponds in width and length to the projected floor area of a standard hospital bed so that the complete system can be easily transported in its mounted and adjusted state.

Abstract: An apparatus for administering ultrasonic shockwaves for medical use includes treatment head for focussing acoustic shockwaves at concretions in human bodies. Clinical treatment often requires two or more treatment heads or several different types of treatment heads with different power requirements to produce fragmentation of concretions. Connectors attached to treatment head cables are provided with electronics containing codes for identifying the type and characteristics of each treatment head and for transmitting that date to a power supply unit. A microprocessor in the power supply unit uses the data provided by the treatment head to automatically deliver the appropriate power ensuring that the treatment head will deliver the correct ultrasonic dose.In another embodiment, electronics are embedded in the treatment heads to provide the same function as described above.
