Title (EN) CATHETER SPLINES AS LOCATION SENSORS
(FR) CANNELURES DE CATHÉTER COMME CAPTEURS D’EMPLACEMENT
Abstract:
(EN) Apparatus, including a probe having a proximal end and a distal end, the probe being configured to be inserted into an organ of a human patient and defining a probe axis. At least two conductors are positioned on the probe at the distal end. The apparatus includes at least two flexible conductive splines, each conductive spline having a first termination and a second termination, the first terminations being electrically connected together at a region on the probe axis beyond the distal end, each second termination being electrically connected to a respective one of the conductors, the splines being configured to bend into respective arcuate forms that encompass a volume. The apparatus also includes a processor configured to receive voltages induced on the splines via the conductors and to calculate a position and orientation of the volume in response to the received voltages.
(FR) La présente invention concerne un appareil, comprenant une sonde comportant une extrémité proximale et une extrémité distale, la sonde étant conçue pour être insérée dans un organe d’un patient humain et délimitant un axe de sonde. Au moins deux conducteurs sont positionnés sur la sonde au niveau de l’extrémité distale. L’appareil comprend au moins deux cannelures conductrices souples, chaque cannelure conductrice ayant une première terminaison et une seconde terminaison, les premières terminaisons étant électriquement connectées ensemble au niveau d’une région de l’axe de sonde au-delà de l’extrémité distale, chaque seconde terminaison étant électriquement connectée à un conducteur respectif, les cannelures étant conçues pour se courber en formes arquées respectives qui englobent un volume. L’appareil comprend également un processeur configuré pour recevoir les tensions induites sur les cannelures par l’intermédiaire des conducteurs et pour calculer une position et une orientation du volume en réponse aux tensions reçues.
