Title
(EN) CATHETER WITH PRESSURE SENSOR AND GUIDANCE SYSTEM
(FR) CATHÉTER À SONDE DE PRESSION ET SYSTÈME DE GUIDAGE
Abstract
(EN)
A catheter terminates at a tip that includes an array of pressure sensors. The sensors are responsive to detect and alert the user to variations of pressure that indicate the tip is either encountering an obstruction or constriction of smaller diameter than the catheter, as well as to guide the catheter through the conduit into which it is being inserted.
(FR)
L'invention concerne un cathéter qui se termine en une pointe qui inclut un réseau de sondes de pression. Les sondes permettent de détecter et indiquer à l'utilisateur des variations de pression qui indiquent que la pointe rencontre une obstruction ou une constriction de diamètre plus petit que le cathéter, ainsi que de guider le cathéter à travers le conduit dans lequel il est inséré.
