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 a medical implant or instrument, particularly a vascular endoprosthesis (stent), comprising a deformable structural part. In order to provide an implant of this type that is magnetic resonance-compatible and can be easily and economically produced, the invention provides that the structural part has a two-layer or multilayer design, whereby layers (2,3) have different electrical and/or magnetic properties. The invention particularly provides that the structural part has a frame structure with openings (5) whereby, in different layers (2,3) of the structural part, the openings (5) are each located at different positions not directly located one above the other.

Abstract: The invention relates to a medicinal implant or instrument, more particularly to a vascular endoprosthesis (1), having a radially dilatable hose part (2) comprised of a tubular knitted fabric of interdigitating meshes composed of one or more individual fibres (9). To provide such an implant or instrument that allows for MR-imaging of the interior of the implant or instrument, the invention proposes that the fibres (9) of the knitted fabric be electrically conductive and form an inductor (7, 8) within a high-frequency resonant circuit.

Abstract: The invention relates to a dilatable balloon implant, which is configured with a limited permeability to liquid. The invention also relates to a vertebroplasty device comprising a balloon implant with a limited permeability to liquid, which is connected to the distal end of an introduction sleeve in such a way that the interior of said implant communicates with the introduction sleeve lumen.
