A system for dilating a stenotic region in an airway of a patient may include advancing a balloon catheter through the airway of the patient to position an inflatable balloon of the catheter within at least a portion of the stenotic region, maintain-ing a position of the catheter relative to the patient, and inflating the balloon of the catheter to dilate the stenotic region of the air-way. A system for dilating a stenotic region in an airway of a patient may include a catheter shaft having an overall length of less than 70 cm, an inflatable balloon disposed along a distal portion of the catheter shaft, and a stylet.

La présente invention concerne un système permettant la dilatation d'une région sténosée d'une voie aérienne d'un patient. Ce système implique généralement de faire progresser un cathéter à ballonnet dans la voie aérienne du patient, de façon à positionner à l'intérieur d'une partie de la région sténosée un ballonnet gonflable porté par le cathéter, à maintenir en position le cathéter par rapport au patient, et à gonfler le ballonnet du cathéter de façon à dilater la région sténosée de la voie aérienne. Un tel système de dilatation d'une région sténosée d'une voie aérienne d'un patient comprend en général une tige de cathéter d'une longueur globale inférieure à 70cm, un ballonnet gonflable disposé le long d'une partie distale de la tige de cathéter, et un stylet.
