(FR) ENSEMBLES ÉLECTRODES DE POINTE DE CATHÉTER INTRAVASCULAIRE
Abstract
(EN)
Aspects of the present disclosure are directed to intravascular electrophysiology catheters which utilize electrodes on flexible electronic circuit(s) to facilitate reduced assembly complexity and cost. In one example embodiment, a distal tip assembly of an electrophysiology catheter is disclosed. The distal tip assembly including a catheter shaft, flexible circuitry, and a distal tip coupled to a distal end of the catheter shaft. The catheter shaft includes an outer surface with a trench extending into the outer surface, and the flexible circuitry is inserted into the trench and coupled to the catheter shaft. The flexible circuitry includes one or more electrodes configured and arranged to sense electrophysiological characteristics of tissue.
(FR)
Des aspects de la présente invention concernent des cathéters d'électrophysiologie intravasculaire qui utilisent des électrodes sur un(des) circuit(s) électronique(s) flexible(s) pour aider à réduire la complexité et le coût d'assemblage. Selon un mode de réalisation donné à titre d'exemple, l'invention concerne un ensemble pointe distale d'un cathéter d'électrophysiologie. L'ensemble pointe distale comprend une tige de cathéter, des circuits flexibles et une pointe distale accouplée à une extrémité distale de la tige de cathéter. La tige de cathéter comprend une surface extérieure avec une tranchée s'étendant dans la surface extérieure, et les circuits flexibles sont insérés dans la tranchée et accouplés à la tige de cathéter. Les circuits flexibles comprennent une ou plusieurs électrodes conçues et agencées pour détecter des caractéristiques électrophysiologiques de tissu.
