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:
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:
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:
A guide wire for introducing an implantable electrode line, wherein the electrode line is particular a heart electrode line for intracardial sensing of cardiac actionpotentials and/or for electrical stimulation or defibrillation of the heart, and wherein the guide wire is adapted for interlocking with the electrode line, and wherein the guide wire comprises a deformation, in particular curved, wavy, V-shaped, zig-zag, or trapezoidal, enlarging the effective contact diameter of the guide wire to a value corresponding essentially to the inner diameter of a lumen of the electrode line or greater than this.
摘要:
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.
摘要:
An electrode device for physiological use, in particular in cardiology, that has an electrically insulating, elastic electrode body which, between internal and external layers (1, 2), has an intermediate layer (3) tailored to their physical properties.
摘要:
A guide wire for introducing an implantable electrode line, wherein the electrode line is a heart electrode line for intracardial sensing of cardiac action potentials and/or for electrical stimulation or defibrillation of the heart, and wherein the guide wire has means for removable interlocking of its end at or near the proximal end of the electrode line.
摘要:
An insertion device (10), by which a medical instrument or an electrode line or a guide wire or a medical therapeutic agent may be inserted into a body cavity, comprises a lumen section (11) manufactured from a flexible plastic material, having a longitudinal axis, a proximal end and a distal end, and a distal end area enclosing the distal end, at least one electrically conductive means (20) in the distal end area to sense physiological signals or stimulate the surrounding body tissue suitably, as well as at least one conductor, which extends from the proximal end to the distal end and is capable of conducting physiological signals to the proximal end and/or stimulation pulses to the distal end. The at least one electrically conductive means is produced from a flexible, not exclusively metallic, electrically conductive substrate.
