Embodiment Construction

[0028] FIG. 1 a diagrammatically shows a sleeve electrode assembly 1 configured according to the solution, which is connected in one piece with a strip-shaped surface element 12 . The surface element 12 and the carrier substrate 4 of the sleeve electrode assembly 1 consist of a uniform material, preferably polyimide, and form a flexible, non-conductive film. Electrical lines 3 run in the carrier substrate 4 in a manner known per se, which are connected on the one hand to the electrodes of the sleeve electrode assembly 1 and on the other hand to the surface of the surface of the strip-shaped surface element 12 . The electrodes 14 formed in the form of solder pads or bonding pads on 13 are connected. For this purpose, the electrical lines are embedded in the carrier substrate 4 and run along the strip-shaped areal elements 12 .

[0029] The carrier substrate 4 has an elongated carrier substrate section 15 which extends along the axis A. FIG. The axis A defines the winding axis...

Abstract

The invention relates to an implantable electric multi-pole connection between an electric implant and an electric feed and discharge structure. The invention is characterised in that a flexible, film-like, electrically non-conductive, strip-shaped surface element is arranged between the implant and the feed and discharge structure. The surface element comprises at least one first surface, on which a number of electrodes n greater than of equal to two is arranged, which are respectively connected to the electric implant by means of electric connection conductors extending at least in parts inside the surface element. The electric feed and discharge structure comprises at least n lines which are electrically insulated from each other and which are electrically connected to one of the n electrodes. The strip-shaped surface element is wound around a winding axis, which adopts the shape of a helix, along a cover surface of a virtual cylinder provided with a cylinder axis which is straightor curved at least in sections.

Description

technical field [0001] The invention relates to an implantable multipolar electrical connection between an electrical implant and an electrical input and output line structure. Background technique [0002] Electronic implants adapted for permanent, or at least long-term, residence in the body are typically used to therapeutically affect organ function. Known examples are cardiac pacemakers or brain pacemakers. Depending on the application purpose and the complexity of the target setting for the treatment, the type of implant has a plurality of electrical input and output lines via which the corresponding implant is supplied with electrical control signals or Conditioning signal as well as power. The number of electrical input or output lines in complex electronic implants can absolutely include twenty and more electrical lines combined into flexible cables through which the implant It is connected to a control device, which is usually combined with an energy source. The...
