Abstract
The present invention is concerned with an electrode and electrode catheter using thin metallic threads or wires, for example, microwires having diameters as low as 10−6 to 10−4 meters or less. The embodiments allow for the efficient mounting of at least one electrode on a catheter, resulting in the creation of a flexible ring-microelectrode that is suitable for, amongst other things, the detection of myoelectrical activity in a patient's muscle, such as the diaphragm or other inspiratory-related muscle.
Claims19
An electrode assembly, comprising:
- an elongated electrode support defining an outer surface, an inner longitudinal conduit, and a wall separating the outer surface and the inner conduit;
- at least one ring-type electrode having a loop portion and a wire portion, wherein the loop portion and the wire portion are both made of a same continuous wire having first and second ends;
- and
- a junction of the first end and of a section of the wire spaced apart from the first end;
- wherein the wire portion comprises the wire between the junction and the second end;
- wherein the loop portion encircles the outer surface generally perpendicular to the elongated electrode support, the wire extends across the wall of the elongated electrode support, and the wire portion extends inside the inner conduit;
- and
- wherein the junction is beneath the outer surface.

An electrode device for a host tube with longitudinal, lateral implement-receiving means, comprising:
- an electrode assembly comprising at least one ring-type electrode having a loop portion and a wire portion;
- and
- an elongated electrode support structured to be mounted in the longitudinal, lateral implement-receiving means on one side of the host tube, the elongated electrode support having at least one transversal indent through which the loop portion of the at least one ring-type electrode is mounted on the elongated electrode support and a longitudinal, inner groove in the elongated electrode support and in communication with the at least one transversal indent;
- wherein, when the elongated electrode support is mounted in the longitudinal, lateral implement-receiving means on one side of the host tube, the longitudinal inner groove forms with a surface of the host tube a longitudinal conduit in which the wire portion of the at least one ring-type electrode is placed to extend along the elongated electrode support and the host tube.
