Abstract: In a vascular anchoring device intended to be introduced into a blood vessel by a catheter and including braces (2) that are expandable in the radial direction, the anchoring device is formed by a substantially hollow-cylindrical part (1) including axially extending braces (2) departing from an end side, and a locking member (3) coaxially guided within the hollow-cylindrical part (1) along a guide wire (4) of the catheter. The locking member (3) carries at least one ramp surface (9) on its end facing the braces (2), which ramp surface causes the braces (2) to expand by an axial displacement relative to the braces (2), and at least one stop (10) cooperating with the hollow-cylindrical part (1) in the expanded position. The guide wire (4) carries a further stop (7) which cooperates with a counter stop surface (8) of the locking member (3), upon displacement of the guide wire (4).

Abstract: A differential pressure measuring cell comprising a measuring membrane (7) which can be impinged on both sides by a fluid, said fluid coming into contact with each side of the measuring membrane (7) via a respective measuring connection (2, 17), a respective additional deformable auxiliary membrane (4, 16) being allocated to both sides of the measuring membrane (7) and each side of said auxiliary membrane that faces a measuring connection (2, 17) being in open contact with the measuring membrane (7) and having a sealing surface (23, 24) which can be deformed during the deformation of the auxiliary membrane (4, 16) to lie against the measuring connection (2, 17) in a sealing manner. The measuring membrane (7) and the auxiliary membranes (4, 16) are configured as structured layers of a chip and consist substantially of Si or polysilicon and/or glass.

Abstract: In an implantable sound receptor for hearing aids, the sound sensor is designed as an optical sensor (5) and arranged within the ear at a distance from the surface of a sound transmission part (3) capable of being excited to acoustic vibrations.

Abstract: A device is disclosed for withdrawing a catheter or a probe from a body cavity or a body vessel with a drive which preferably is a friction drive and engages the axially movable part of the catheter. The drive is formed by at least one roller which is mounted for rotation around a shaft extending transversely to the direction of pull, which roller cooperates with at least one spring-loaded counter-roller, the rollers enclosing the catheter or the probe, with at least one roller being connected to a driving motor.
