Title
(EN) PERCUTANEOUS CATHETER SYSTEM AND METHOD FOR RAPID DIAGNOSIS OF LUNG DISEASE
(FR) SYSTÈME DE CATHÉTER PERCUTANÉ ET PROCÉDÉ DE DIAGNOSTIC RAPIDE DE MALADIE PULMONAIRE
Abstract
(EN)
A percutaneously delivered medical device and its method of use includes a catheter, at least two electromagnetic sensing coils located within the distal tip of the catheter, and at least one within the proximal handle, and a multi-element planar ultrasound transducer array located within the distal tip of the catheter and configured to transmit and receive ultrasonic energy in at least two imaging modes. The device also includes an imaging system coupled to the ultrasound transducer and is used for creating an image of tissue in a first target plane that extends orthogonally from the catheter body. The medical device also includes a backscatter evaluation system for use in receiving and evaluating the acoustic spectral characteristics of tissues within a second target area within the first target plane.
(FR)
L'invention concerne un dispositif médical administré par voie percutanée et son procédé d'utilisation comprenant un cathéter, au moins deux bobines de détection électromagnétique situées à l'intérieur de la pointe distale du cathéter, et au moins une bobine à l'intérieur de la poignée proximale, et un réseau de transducteurs ultrasonores planaires à éléments multiples situé à l'intérieur de la pointe distale du cathéter et conçu pour émettre et recevoir de l'énergie ultrasonore dans au moins deux modes d'imagerie. Le dispositif comprend également un système d'imagerie couplé au transducteur ultrasonore et est utilisé pour créer une image de tissu dans un premier plan cible qui s'étend orthogonalement à partir du corps de cathéter. Le dispositif médical comprend également un système d'évaluation de rétrodiffusion destiné à être utilisé pour recevoir et évaluer les caractéristiques spectrales acoustiques de tissus à l'intérieur d'une seconde zone cible à l'intérieur du premier plan cible.
