Title
(EN) CATHETERIZATION METHOD AND APPARATUS
(FR) MÉTHODE ET APPAREIL DE CATHÉTÉRISATION
Abstract
(EN)
Catheterization methods and apparatuses allow sensing of pressures inside the heart and for removing air from catheters. A delivery system can use the same components that are used to deliver a valve repair or replacement device to measure the pressure in the atrium or other heart chamber. A pressure sensor can be included in one of the catheters of the delivery system or pressure can be sensed through the same port that is used to flush a catheter. The delivery system can be inserted into an atrium of the heart, delivering the valve repair or replacement device to the native valve, such as the mitral valve, the tricuspid valve, the aortic valve, or the pulmonary valve.
(FR)
L'invention concerne des méthodes et des appareils de cathétérisation qui permettent une détection de pressions à l'intérieur du cœur et une élimination de l'air des cathéters. Un système de mise en place peut faire appel aux mêmes composants que ceux utilisés pour mettre en place un dispositif de réparation ou de remplacement de valvule servant à mesurer la pression dans l'oreillette ou dans une autre chambre cardiaque. Un capteur de pression peut être compris dans l'un des cathéters du système de mise en place ou une pression peut être détectée à travers le même orifice qui sert à rincer un cathéter. Le système de mise en place peut être inséré dans une oreillette du cœur, mettant en place le dispositif de réparation ou de remplacement de valvule par rapport à la valvule native, telle que la valvule mitrale, la valvule tricuspide, la valvule aortique, ou la valvule pulmonaire.
