Patent

CA 2594409

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.

La présente invention concerne une électrode et un cathéter à électrode utilisant de minces fils métalliques, par exemple des microfils qui présentent un diamètre inférieur ou égal à 10-6-10-4 mètres. Cette invention permet de monter efficacement au moins une électrode sur un cathéter, ce qui permet d'obtenir une microélectrode annulaire souple qui est conçue, entre autres, pour détecter une activité myoélectrique dans un muscle d'un patient, par exemple dans le diaphragme ou un autre muscle inspiratoire.
