Abstract: Disclosed herein is a system for navigated punction, biopsy or ablation comprising a mobile electromagnetic field generator for generating an electromagnetic navigation field which is connected to an apparatus for medical imaging, a needle-like instrument (16), comprising a sterile distal portion (22) and an optionally non-sterile proximal portion (20), a removable protection device (30) for encapsulating the sterile distal portion (22), a sensor (38) suitable for carrying out measurements allowing for determining the position of the sensor (38) within the navigation field, and a sensor carrier (26). The sensor carrier (26) comprises an elongate carrier body (36) having proximal and distal ends. The sensor (38) is attached to or enclosed by said carrier body (36) close to its distal end.

Abstract: A mounting device for reversibly mounting at least one electromagnetic field generator on an ultrasonic probe for orientating the electromagnetic field generator with respect to the ultrasonic probe in at least one mounting position is disclosed. The mounting device comprises at least one first fastening structure. The mounting device is connectable to the electromagnetic field generator via the first fastening structure.

Abstract: A kit for a fiducial marker-based registration of preinterventional image data to an intra-interventional scene is disclosed.

Abstract: The invention concerns a method for treating a surface for the protection and functionalisation of polymers (4) by gas plasma deposit in a confined chamber (10) of one or several silicon alloy layers (43). The silicon alloy is selected among silicon and its oxides, nitrides, oxynitrides; the deposit is performed at a temperature less than the degradation temperature of the polymer, and a physico—chemical surface pre-treatment by plasma is performed in the same chamber before the silicon alloy is deposited; the pre-treatment consisting in a surface treatment comprising etching a surface zone of the polymer and step which consists in depositing a polymeric carbon compound.

Abstract: The electromagnetic valve comprises a valve housing, a valve slider and two electromagnets. The valve slider is displaceably arranged in a through-bore in the housing. The through-bore and the valve slider are provided with a hard coating in order to increase the number of switching movements.
