A vessel electrode line () for pacemaker stimulation and/or for sensing cardiac actions in the region of the atrium has an oblong base body () that receives at least one electrode supply line, and at least one electrode () that is mounted on the base body, with the effective diameter of the electrode(s) being nearly identical to the diameter of the base body, and with fixing elements () that essentially do not act as an electrode, and particularly have at least a partial insulating surface, being provided for fixedly positioning the electrode(s) with respect to the vessel wall.

Vessel electrode line

An electrode arrangement is provided having an electrode line which has a closed casing for sealing off its interior relative to the surrounding area. At its distal end, electrically conducting surface regions serve as electrodes. A fixing mechanism anchors the distal end in a body tissue, in particular heart tissue and is adapted to be separable from the rest of the electrode line in such a way that the rest of the electrode line is also closed at its distal end when the fixing mechanism is separated off. The interior of the electrode line is sealed off relative to the surrounding area even when the fixing element is separated off. The electrode arrangement is characterized by a mechanism for separating off the fixing mechanism, which is adapted to effect separation by virtue of forces acting axially within the electrode line.

Break-away extractable lead

A catheter for the introduction into blood vessels having a lumen and guide means arranged therein wherein the guide means include a pre-bent wire ( ) displaceable in the longitudinal direction of the catheter ( ) and the catheter ( ) has at its distal end an exit lock means ( ) such that the pre-bent wire ( ) can issue from the catheter ( ) through the exit lock means ( ) at the distal end.

Catheter having a guide sleeve for displacing a pre-bent guidewire

An implantable electrode arrangement which includes an electrode line ( ) with a plurality of electrically conductive surface regions ( ) in the region of the distal end of the electrode line for outputting electrical signals to a heart and/or for receiving signals from a heart, which can be electrically connected by way of the electrode line ( ) to a cardioelectric device such as a defibrillator or cardiac pacemaker, which device receives electrical signals and/or outputs pulses, wherein there are switching means ( ) which are of such an arrangement and configuration that the connection between individual ones of the electrically conducting surface regions ( ) and the cardioelectric device can be permanently switched on or off in the region of the electrode line ( ).

An implantable electrode arrangement which includes an electrode line ( ) with a plurality of electrically conductive surface regions in the region of the distal end of the electrode line ( ) for outputting electrical signals to a heart and/or for receiving signals from a heart, which can be connected by way of at least one electric line ( ) of the electrode line ( ) to a cardioelectric device such as a defibrillator or cardiac pacemaker, which device receives electrical signals and/or outputs pulses, wherein arranged in the electrode line ( ) are switching means which are connected to the electric line ( ) and at least one electrically conducting surface region and which are such that they can make or break a connection between the electrically conducting surface region and the cardioelectric device in the region of the electrode line ( ), and arranged in the electrode line ( ) are control means which are connected to the electric line ( ) for receiving control signals and to the switching means for switching over from a state of the switching means of breaking the connection between the electric line ( ) and the electrically conducting surface region and a state of the switching means of making the connection or vice versa.
