Abstract: Certain embodiments of the present invention concern an implantable electrode line having a proximal and a distal end, an outer electrode line surface and an electrode line longitudinal axis. The implantable electrode line is characterized in that the electrode line in the region of the distal end has a surface region with a microstructure, the surface region being provided for lateral contact with a vessel wall and being arranged at a spacing relative to the distal end which measures a plurality of electrode line diameters. The microstructure is formed by a plurality of microstructure elements which are arranged on the electrode line surface and which are distributed over the surface region both in the longitudinal direction and also in the peripheral direction and which have a component extending radially, wherein the microstructure elements are of a radial extent which is a fraction of the electrode line diameter.

Abstract: The invention relates to an active fixation cardiac electrode lead having a fixation helix movably placed in a housing at the electrode lead's distal end so as to be extended out of the housing's distal end and retraced into an inner space enclosed by the housing. The housing has a wall and a protrusion formed in the wall that protrudes into the inner space into interspaces between windings of the fixation helix. The protrusion causes an axial movement of the helix when the helix is rotated around its longitudinal axis. The protrusion is an integral part of the housing's wall which is bent or embossed to form the protrusion.

Abstract: A screw-in electrode probe for cardiological application comprises an oblong electrode body (1), a supply line (10) running therein, and an electrode head (3) on the distal end (2). The latter is provided with housing (5), a shaft (6) mounted therein so it is rotatable and axially displaceable, and a corkscrew-like screw-in electrode (4) on the shaft (6). A contact spring in the form of an essentially planar spiral spring (11) is situated between these components, whose leg ends (12, 13) are in sliding contact with the housing (5) or the shaft (6), respectively, while exerting a radially directed spring force (F).

Abstract: A catheter for cardiovascular application includes an elongated catheter shank; a lumen inside the catheter shank; a mandrel sleeve that extends in the lumen; a guide wire which runs in the mandrel sleeve and is extendable through a sluice gate out of the catheter at a distal end thereof; and a sealing unit for sealing the lumen, the sealing unit being disposed proximally in front of the sluice gate and reversibly pierced by the replaceable mandrel sleeve.

Abstract: An implantable electrode device, particularly a cardiological electrode device, comprises an oblong, hose-like electrode body (1) and a helical screw-in electrode (8), which is displaceable on the distal end (3) of the electrode body (1) between a retracted passive position inside the electrode body (1) and an extended, active fixing position outside the electrode body (1), which is displaceable by a rotational movement of its electrode line (7), with the aid of a spindle-type cam controller (13, 13?, 13?), between the retracted passive position and the extended fixing position. The cam controller (13, 13?, 13?) is formed by a separate cam coil (16, 16?, 16?), which is fixedly mounted in the electrode body (1) and coaxially to the electrode supply line (7) and, in addition, by a cam body (17, 25), which is mounted on the electrode supply line (7) rotationally fixed thereto and engages in the cam coil (16, 16?, 16?).

The shaping is three-dimensional and has line portions enclosing an elongated hollow space, with a pitch direction that is different in relation to the longitudinal direction of the hollow space.

Abstract: The invention concerns a fixing for implantable electrodes and catheters. The object of the present invention is inter alia to provide a fixing which takes better account of the different demands in the course of time of ordinary use of the implantable electrodes or catheters. For that purpose the fixing is distinguished in that it includes at least one first structural element comprising a biodegradable material, namely a biodegradable magnesium alloy.

Abstract: The invention concerns an electrode line (12) for an implantable intravascular electrostimulation device (10), wherein the electrode line (12) is electrically conductively connected with its proximal end (16) to the electrostimulation device (10) and with its distal end (18) to one or more functional elements. It is distinguished in that the electrode line (12) comprises an intrinsically conductive polymer in which the individual polymer chains of the polymer are so oriented that there is a high electrical conductivity in the axial direction of the electrode line (12) but not in the radial direction (electrical anisotropy).
