Title
(EN) OCCLUSION DETECTION BY PRESSURE MEASUREMENT
(FR) DÉTECTION D'OCCLUSION PAR MESURE DE PRESSION
Abstract
(EN)
A system, device and method for left atrial appendage occlusion detection is disclosed. The system for occlusion detection comprises a sheath; a delivery system comprising: a delivery catheter extending between a proximal end and a distal end; and a handle coupled to the proximal end of the delivery catheter; a medical tool coupled to a distal end of the delivery catheter at a target location within a portion of an organ of a patient, the medical device comprising a hub including a bore defining an axis, an occluder portion coupled to the hub and an anchor portion extending between a first end and a second end; at least one pressure sensor configured to measure a pressure of the target cavity while blood is suctioned form inside the left atrial appendage; and at least one processor configured to process the pressure measurement acquired from the at least one pressure sensor.

L'invention concerne un système, un dispositif et un procédé de détection d'occlusion d'appendice auriculaire gauche. Le système de détection d'occlusion comprend une gaine ; un système de pose comprenant : un cathéter de pose s'étendant entre une extrémité proximale et une extrémité distale ; et un manche couplé à l'extrémité proximale du cathéter de pose ; un outil médical couplé à une extrémité distale du cathéter de pose au niveau d'un emplacement cible à l'intérieur d'une partie d'un organe d'un patient, le dispositif médical comprenant un moyeu comprenant un alésage définissant un axe, une partie d'occlusion couplée au moyeu et une partie d'ancrage s'étendant entre une première extrémité et une seconde extrémité ; au moins un capteur de pression configuré pour mesurer une pression de la cavité cible pendant que le sang est aspiré depuis l'intérieur de l'appendice auriculaire gauche ; et au moins un processeur configuré pour traiter la mesure de pression acquise à partir du ou des capteurs de pression.
