Electrode arrangement
First Claim
1. An electrode arrangement, comprising:
- an electrode line with at least a first element for fixing the electrode line to body tissue, the first fixing element being spaced apart from a distal end of the electrode line, wherein the first fixing element is fixedly connected to the electrode line and has a free end that extends tangentially outwardly from the electrode line, the first fixing element being configured to penetrate into the body tissue that is adjacent to the electrode line when the electrode line is rotated about a longitudinal axis thereof, the first fixing element having at least one portion that is wound in a helical coil-like manner around the electrode line substantially coaxially at a spacing therefrom and which is rigidly connected thereto.

Abstract
An electrode arrangement provides an electrode line (10) carrying at least a first fixing element (16) which is designed to fix the electrode line to body tissue, especially the myocardium of a heart, and which is arranged at a spacing relative to the distal end (12) of the electrode line (10), wherein the first fixing element (16) is fixedly connected to the electrode line (10) and has a free first end (40) which has a component of extension in a direction tangential with respect to the electrode line (10) and which is of such a configuration that the first fixing element (16) penetrates into body tissue that is adjacent to the electrode line in the situation of use by a rotary movement of the electrode line (10) about the longitudinal axis thereof.

18. An electrode arrangement, comprising:
-
an electrode line with at least a first element for fixing the electrode line to body tissue, the first fixing element being spaced apart from a distal end of the electrode line, wherein the first fixing element is fixedly connected to the electrode line and has a first and a second free end, each of which extends tangentially outwardly from the electrode line, the first fixing element being configured to penetrate into the body tissue that is adjacent to the electrode line when the electrode line is rotated about a longitudinal axis thereof, the first and second free ends having opposite axial orientations, with the first fixing element fixedly connected to the electrode line between the first and second free ends. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
