Abstract: The invention relates to a height restoring device for restoring the height of and stabilizing the spinal column, in particular for stabilizing broken vertebral bodies or contused intervertebral discs, which device can be arranged in an insertion position in a compression-fractured vertebral body or between adjacent vertebral bodies and once there, can be transferred from the insertion position into an expansion position by means of an expansion apparatus.

Abstract: A system comprising a sluice and a catheter. The catheter including an inner, a middle and an outer tube. A stent is disposed in a distal-end portion of the catheter between the inner and outer-tube. The middle-tube ends distally at the proximal end of the stent. An actuating unit having a drive unit provided in the proximal region of the catheter for releasing the stent. A connecting portion is provided between the drive unit and the sluice. The drive unit is cooperating with the middle-tube and the connecting portion where the drive unit is operated the middle-tube is displaced in the distal direction and the actuating unit together with the outer-tube attached thereto is displaced in the proximal direction. The inner-tube is cooperating with the middle-tube and/or the connecting portion and/or the drive unit in such a way that the inner-tube is displaced at least to some extent relative to the actuating unit.

Abstract: An oil filter assembly (10) has a receiving chamber (18) that can be closed by a cover element (14) and a spring-loaded supporting tube (22) that is fixed in the receiving chamber and is designed to receive a filter element (20) that can be radially traversed by oil. The supporting tube (22) is axially displaceable between an operating position and a drain position in such a way that, in the operating position when the receiving chamber is closed by the cover element (14), the tube closes a drain opening (42). When the receiving chamber is open in the drain position, the tube releases the drain opening. The supporting tube is mounted to rotate through a rotational angle that is limited by two rotational stops (41, 43) in the housing and the cover element has follower sections (66, 68, 70) that co-operate with the supporting tube and/or filter element to rotate the supporting tube through the rotational angle when the cover element is screwed on and/or unscrewed.

The cover element (14) has a supporting tube contact area (58) on the side facing the receiving chamber in such a way that during the closing of the receiving chamber (14) when the filter element is located on the supporting tube (22), pressure is exerted on the tube by the support tube contact area (58), thus displacing the tube into the operating position.

Abstract: An oil filter arrangement, has a housing (12) with a receiving space (18) for a filter element (20) which can be inserted into the housing and through which oil can flow radially, with an oil inlet (34) and an oil outlet (32), and with a supporting tube (22) which is present in the receiving space and supports the filter element. The supporting tube is inserted into the receiving space and is fastened to the housing in such a manner that it remains in the housing when the filter element is exchanged.
