Abstract

Cathéter utilisable p. ex. pour des ablations dans le myocarde. Ce cathéter possède un manche, une tige, et une extrémité distale pouvant être pliée en forme de J, contenant une pointe électrode et des électrodes annulaires. La pointe électrode est rotative axialement et présente des parties isolées et des parties non isolées. Lorsque la pointe électrode tourne, on observe l'impédance entre l'électrode et un seuil de référence. Lorsque l'impédance atteint un maximum, cela indique que la partie non isolée est en contact avec le tissu et que la partie isolée fait face au flux sanguin. Un électrogramme peut être relevé à partir de l'électrode, ou un courant d'ablation peut être appliqué à cette dernière. Ce cathéter permet de réduire les court-circuitages du signal ou du courant occasionnés par le sang.
