Title (EN) DILATATION CATHETER ASSEMBLY WITH CUTTING ELEMENT
(FR) ENSEMBLE CATHETER DE DILATATION A ELEMENT COUPANT
Abstract:
(EN) A dilatation catheter assembly (10) is set forth which permits dilatation and incision of tissue whereby trauma and damage to the tissue due to uncontrolled tearing is reduced or eliminated. The assembly comprises an elongated tubular body (13) having a distal end that carries a dilatation bladder (15) and cutting element (17) carried on the exterior of the bladder and that moves radially in concert with the exterior of the bladder as the bladder is inflated and deflated. The bladder is not linearly extensible and is extensible only to a specified volume and/or the cutting element utilized is a radio frequency cutting element.
(FR) Ensemble cathéter de dilatation (10) permettant d'opérer une dilatation ainsi qu'une incision de tissus, de manière que l'on réduit ou l'on élimine le trauma et les lésions occasionnées aux tissus par une déchirure non contrôlée. L'ensemble comprend un corps tubulaire allongé (13) présentant une extrémité distale portant une vessie de dilatation (15) ainsi qu'un élément coupant (17) porté à l'extérieur de la vessie et se déplaçant radialement simultanément avec l'extérieur de la vessie à mesure que l'on gonfle et que l'on dégonfle cette dernière. La vessie est extensible de manière non linéaire et elle est extensible uniquement jusqu'à un volume spécifié et/ou l'élément coupant utilisé est un élément coupant à hautes fréquences.
