Title
(EN) ENDOVASCULAR CUTTING CATHETER AND RELATED METHOD
(FR) CATHÉTER DE COUPE ENDOVASCULAIRE ET PROCÉDÉ ASSOCIÉ
Abstract
(EN)
An apparatus for treating a lesion in a vasculature has a catheter shaft (12) with a plurality of openings (16), which may be axially spaced. One or more cutters (18, 18') are adapted for moving from a retracted position to a deployed position projecting from one of the plurality of openings for cutting the lesion, such as by being biased toward the opening and retracting upon engaging a leading edge thereof when the support is advanced proximally. A shaft forming part of the catheter may include a plurality of lateral openings and a plurality of cutters. The cutter(s) may be attached to a support adapted for moving independently within the shaft from a first position in which the cutter(s) move to a deployed position to project from a corresponding one of the plurality of openings for cutting the lesion. Related methods are also disclosed.
(FR)
L'invention concerne un appareil pour traiter une lésion dans un système vasculaire, comprenant une tige de cathéter (12) ayant une pluralité d'ouvertures (16), qui peuvent être espacées axialement. Un ou plusieurs éléments de coupe (18, 18') sont conçus pour se déplacer d'une position rétractée à une position déployée faisant saillie à partir de l'une de la pluralité d'ouvertures pour couper la lésion, par exemple en étant sollicité vers l'ouverture et se rétractant lors de l'engagement d'un bord avant de celui-ci lorsque le support est avancé de manière proximale. Une tige faisant partie du cathéter peut comprendre une pluralité d'ouvertures latérales et une pluralité de dispositifs de coupe. L'au moins un dispositif de coupe peut être fixé à un support conçu pour se déplacer indépendamment à l'intérieur de l'arbre à partir d'une première position dans laquelle l'au moins un dispositif de coupe se déplace vers une position déployée pour faire saillie à partir d'une ouverture correspondante de la pluralité d'ouvertures pour couper la lésion. L'invention concerne en outre des procédés associés.
