Abstract: A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.

Abstract: An appliance (1) for examining biological tissue comprises a light injection means (102) for injecting visible and/or close infrared light into the biological tissue, a detector (104) for converting light signals that exit the biological tissue into detection signals, an output device (130) allocated to the detector (104) for outputting information that depends on the detection signals and a shield (20; 106) allocated to the director (104) for shielding the detector (104) against extraneous light at least in the injected wave range. The appliance is also provided with a control device for controlling whether the arrangement of light injection means (102) and/or a detector and/or a shield (20; 106) is correct in relation to a substrate. The appliance can be used for examining biological tissue and supports the user for forcing the user to arrange the essential components of the examination device in the prescribed order before measuring.

Abstract: The invention relates to a device for measuring physical quantities in the eye, especially for measuring the intraocular pressure. The inventive device comprises a foldable telemetry system containing a coil (1) which is flatly arranged on a foldable support. Said coil is completely embedded in the biocompatible implant material together with an electronic mobile (4) that contains the electronic of the telemetry system.
