摘要:
An electrode device for cardiological or neurological electrodiagnosis and/or electrotherapy comprises an elongated electrode body (12), at least one electrode (14, 16) in the vicinity of the distal end (24) of the electrode body (12), and an electrode conductor (44) for the electrical connection of the electrode (14, 16). The electrode conductor (44) has a fibrous structure (52) with anisotropic conductivity so that the specific conductivity of the electrode conductor (44) is significantly higher in its longitudinal direction than in its transverse direction.

摘要:
An electrode for interventional purposes, such as a cardiac pacemaker, neurostimulation, or ICD electrode, comprises an elongate electrode body (6), at least one electrode pole (5) in the area of the distal end (4) of the electrode body (6) for delivering an intervention pulse, at least one supply line (7) running in the electrode body (6) to the at least one electrode pole (5), and an electrode sheath (8) for insulating the supply line (7). The first and/or second material is produced in such a way that it contains conductive particles embedded in a polymer matrix in a concentration which is greater than or equal to the percolation threshold.

摘要:
The aim of the invention is to provide an implant for releasing an active substance into a vessel through which a body medium flows. This aim is achieved by the inventive implant for releasing an active substance into a vessel through which a body medium flows. Said implant comprises a base that consists of a biodegradable material as the carrier of the active substance to be released. The body medium flows around said base on the inside and/or outside thereof.
摘要:
An implant for releasing an active substance into a vessel through which a body medium flows. The implant release an active substance into a vessel through which a body medium flows downstream from the location of the implant. A base of a biodegradable material is a carrier of the active substance to be released. The body medium flows past the implant and the active substance is release. The implant is configured so that the active substance does not contact a vessel wall at the location of implant.
摘要:
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 account of the different demands in the course of time of ordinary use of the implantable electrodes or catheters. For that purpose the fixing includes at least one first structural element comprising a biodegradable material, namely a biodegradable magnesium alloy.

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.
摘要:
An implantable medical electrode device, in particular a cardiovascular cardiac pacemaker or defibrillator electrode device, comprises an elongate, tubular electrode body (2), a fixing zone (4) in front of the distal end (3) of the electrode body (2), in which the externally closed peripheral envelope (8) of the electrode body (2) is reversibly expandable into a body lumen (27) for detachable fixing of the electrode device (1), and expansion means, situated in the fixing zone (4), for controlling the expansion and contraction in the fixing zone (4).
摘要:
A catheter, in particular for insertion of heart-pacemaker- or ICD-electrodes into a patient's body, comprises a catheter wall and a reinforcement therein for stabilization of the catheter. The reinforcement is a profile element which is adjusted to the desired mechanical properties of the catheter in the axial and peripheral direction thereof.
