Abstract: Device (1) for positioning interventional instruments within an examination space, with a tomograph (11) for recording diagnostic image data of the examination space, a patient table (4) that can be moved transversely and/or rotated, at least one radiation unit (2, 2A, 2B, 2C) with a radiation source, which generates directed electromagnetic radiation, at least one carrier device (3, 3A, 3B, 3C) associated with the respective radiation unit (2, 2A, 2B, 2C), a control unit for orientation of the respective radiation unit (2, 2A, 2B, 2C) and of the patient table (4) according to the access and target points selected based on the diagnostic image data, wherein each radiation unit (2, 2A, 2B, 2C) is arranged movably with a first degree of freedom on the respective carrier device (3, 3A, 3B, 3C) and the carrier device (3, 3A, 3B, 3C) permits the mobility of this radiation unit (2, 2A, 2B, 2C) relative to the patient table (4), wherein an access point and the relative orientation of an instrument to reach a target

Abstract: The invention relates to an operating table top (4) consisting of one or several basic sections (5) and one or several modules (6), with such modules (6) and basic sections (5) being adjustable relative to each other and such modules (6) being designed so as to be separable from the operating table top (4), and with such modules (6) being designed so as to be replaceable with additional supporting surfaces (8) separably connected to the basic sections (5), and with the operating table top (4) and its attached additional supporting surfaces (8) being of suitable design so that they can be introduced into radiographic equipment, magnetic resonance imaging and/or computer tomography systems and radiographic, magnetic resonance or computer tomographic images can be produced. Moreover, the invention relates to a pertinent operating table system as well as a pertinent operating table (1).

Abstract: The invention relates to a device for the application of bone cement, in particular in the field of vertebroplasty, comprising an application conduit (1) guiding the bone cement towards the application area and a flexible piston rod (2) longitudinally movable in the application conduit (1) and provided with a piston (3) arranged at the distal end of the rod (2), said piston being in contact with and providing a seal at the internal wall of the application conduit (1), with the piston rod (2) protruding proximally from said application conduit (1) and the application conduit (1), at least partially, being formed into one or several windings (5). A spirally or helically wound application conduit (1) results in the effective useful length of the application conduit (1) being relatively great with the overall dimensions of the application device on the other hand still being moderate.

Abstract: The invention relates to the use of a spongy material for the production of an implant (10) designed to obstruct a cyst neck (3). As spongy material especially the polyvinyl alcohol Ivalon can be employed. The invention furthermore relates to a set of instruments for the introduction of such an implant (10) made of a spongy material into a cyst neck (3) with said set of instruments consisting of a puncture needle (5) for the insertion of a guide wire (6), a guide wire (6) the distal end of which can be introduced into the cyst neck (3), an implant needle (7) provided at its proximal end with a connection element, a feeding unit (8) that can be attached via the connection element to the implant needle (7), and the implant (10) proper which consists of a spongy material and can be introduced via said feeding unit (8) through the implant needle (7) into the cyst neck (3). The inventive set of instruments may in particular be used for the treatment of Baker's cysts.

Abstract: Needle electrode for therapy, especially percutaneous galvanotherapy of tumors, which can be visualized by image-generating procedures, which is provided with a coating of platinum and/or an insulating material, as well as a process for the manufacture of the needle electrode according to the invention.
