Abstract

Le cathéter de cartographie ci-décrit comprend un corps allongé destiné à être inséré dans l'appareil vasculaire du patient. Une extrémité distale du corps allongé comprend une partie distale qui comporte une pluralité d'électrodes, une partie proximale située à proximité de la partie distale, et une partie de dimension réduite placée entre les parties proximale et distale. L'extrémité distale est formée, au moins en partie, à base d'un matériau à mémoire de forme qui adopte une forme préformée, une fois libéré d'un espace confiné. La forme préformée comprend une première boucle formée, au moins en partie, par la partie distale. La première boucle est transversale par rapport à un axe longitudinal de la partie proximale. La partie de dimension réduite est conçue et agencée pour se courber de façon à ce que la section de dimension réduite avance distalement dans la première boucle quand celle-ci est maintenue dans une position fixe et qu'une force est appliquée distalement sur l'axe longitudinal de la partie proximale.
