Problems solved by technology

A cylindrical conductor is flexible, but if it is bent too sharply, conductive elements on the printed circuit board may break or be damaged
Clinically, it is often necessary to bend catheters, which may promote wire breakage on cylindrical multi-conductor elements

Embodiment Construction

[0015] figure 1 A catheter with a curved conductor carrier designed according to the prior art is shown. The catheter is made of a cylindrical rod 1 made of a flexible material and has two cylindrical lumens 2a-b extending along the length of the catheter. The catheter is designed to convey fluids through its lumen or to accommodate conductor carriers for electrodes in its lumen. Arranged in an interior space 2b is a conductor carrier 3, around which two inner electrodes 4a-b are fastened. The inner electrodes are electrically connected to the outer electrodes 10a-b to facilitate measurement or to apply energy to the organ via leads running down the catheter to the electrodes 9a-b.

[0016] Conductor carriers in the prior art consist of a rectangular element in a flat state of a flexible printed circuit rolled into a cylindrical shape, and said element is fixed in a cylindrical shape by filling the cylinder with flexible glue. The conductor carrier in the flat state is very...

Abstract

The invention relates to a flexible conductor carrier (5, 5a-b, 6, T) comprising an elongated inserted section (5, 5a-b, 6) intended to be arranged in a lumen (2a-b) in a flexible catheter. The inserted section (5, 5a-b, 6) comprises a flat section (5, 5a-b) and a rolled section (6). The flat section provides higher tolerance to bending than a fully-rolled counterpart. Typically, at least one electrode (4a-b) is fixed around the rolled section (6).

Description

technical field [0001] The invention relates to a flexible conductor carrier and a catheter provided with a conductor carrier according to the preambles of the claims. Background technique [0002] Flexible catheters having conductors extending along the interior of the catheter are known. Such a flexible catheter is described in patent application publication number WO2007139479. This document describes an elongated rectangular flexible circuit board that is rolled up to form a cylindrical element and constitute a conduit. A cylindrical conductor is flexible, but if it is bent too sharply, conductive elements on the printed circuit board may break or be damaged. Clinically, it is often necessary to bend the catheter, which may promote breakage of the wires on the cylindrical multi-conductor element. Contents of the invention [0003] It is therefore an object of the present invention to provide a flexible conductor carrier which is more resistant to bending than conduc...
