Abstract: In an implantable pressure measuring device, in particular for measuring an intracranial pressure, is provided. In order to simplify production, it is proposed that the pressure measuring device comprises an implant housing and a pressure measuring sensor, which is arranged in the implant housing, with one or more load cell(s). The implant housing has an opening. The pressure measuring sensor is provided with a coating applied directly to the load cell(s). The pressure measuring sensor is arranged in the implant housing in such a way that the opening provides direct access to the load cell(s) for a fluid surrounding the pressure measuring device and therefore the surrounding pressure acts directly on the coated load cell(s) of the pressure measuring sensor. The coating is produced from a para-xylylene-based polymer material.

Abstract: A surgical instrument is provided having proximal and distal end sections and a central section extending therebetween. An hollow outer shaft extends from the proximal to the distal end section. A drive element is rotatably mounted in the outer shaft and a tool is coupled to the drive element at the distal end section. The drive element comprises a flexible section arranged between the proximal and distal end sections which consists of a plurality of ring segments each of which has a first and a second end region. The first end region comprises projections which protrude in the axial direction and the second end region comprises recesses for accommodating the projections. The ring segments intermesh in an articulated manner by means of the projections and recesses. The outer shaft comprises an articulation zone which connects the distal end section and the central section together in an articulated manner.

Abstract: A surgical instrument is provided, comprising proximal and distal end sections each comprising an area of articulation, as well as a flexurally rigid central section arranged therebetween. The proximal end section can be connected to an actuating device. A tool which can be driven by means of a drive element can be connected to the distal end section. To provide greater flexibility and a greater working area, the instrument further comprises outer and inner hollow cylindrical shafts and a control element which is arranged between the shafts. Two or more longitudinal elements extend at least substantially from the proximal to the distal area of articulation of the instrument and transfer traction and/or pressure forces. The longitudinal elements are arranged at essentially regular angular distances in a circumferential direction of the instrument and are connected to one another in the circumferential direction at their proximal and distal ends.

Abstract: A control device is provided, particularly for use in endoscopes or the like. The control device has proximal and distal end sections which each incorporate an articulation zone and a bending resistant central section arranged therebetween. The control device also comprises outer and inner hollow cylindrical shafts and a control element arranged between the shafts. Force transmitting longitudinal elements extend substantially from the proximal to the distal end section. The longitudinal elements are arranged at angular intervals in the circumferential direction of the control device and are connected together in the regions of their proximal and distal ends in the circumferential direction. The control device further comprises a holding device with the aid of which a part of an articulation zone is fixable, in a bending resistant manner, with respect to the longitudinal direction of the central section or to a functional unit adjoining the proximal or distal end section.

The control device has proximal and distal end sections each comprising an area of articulation and a central section arranged therebetween. The control device also comprises outer and inner hollow cylindrical shafts and a control element arranged between the shafts. Two or more longitudinal elements extend substantially from the proximal to the distal end section and transfer force. For an optimized control function, the longitudinal elements are arranged at essentially regular angular distances in a circumferential direction of the control device and are connected to one another in the circumferential direction in the region of their respective proximal and distal ends. The distal ends of the longitudinal elements are secured in the circumferential direction in angular positions which are different to the angular positions, in which the respectively associated proximal ends are secured.

Abstract: The present invention relates to a surgical clip comprising a first arm and a second arm, the first and second arms having first and second clamping surfaces facing each other, and the first and second arms being mounted for movement relative to each other, and further comprising a distance retaining device for keeping the first and second arms permanently spaced from each other. The present invention also relates to a surgical method for treating an aneurysm, the method comprising: applying a surgical clip to the aneurysm, the clip comprising a first arm and a second arm, aid first and second arms having first and second clamping surfaces facing each other for clamping the aneurysm therebetween, the first and second arms being mounted for movement relative to each other, and the first and second arms being kept permanently spaced from each other, wherein the aneurysm is clamped between the arms kept permanently spaced from each other.

Abstract: In order, in an application instrument for an aneurysm clip comprising two clamping jaws, which are movable relative to one another and between them accommodate the aneurysm clip, as well as actuating elements for moving the clamping jaws towards and away from one another and thereby for opening and closing the aneurysm clip, to assist the surgeon with the controlled closing movement of the aneurysm clip, it is proposed that the application instrument comprises a damping element, which during closing of the aneurysm clip imposes a retarded mutual movement of the clamping jaws.
