Patent

CA 2251341

Apparatus and methods are provided for re-canalizing stent regions (M) within the vasculature which has become re-stenosed. A shearing body (20) is displaced within the stent region in order to dislodge the stenotic material from an interface envelope defined by the inner surface of the stent. Usually, the shearing body will be compliant and sized slightly larger than the stent in order to remove stenotic material substantially uniformly around the entire interface envelope. The shearing body may be in the form of a brush (96), helical row (34), spaced apart disks (150), solid compressible body, or a variety of other specific configurations.

L'invention concerne un appareil et des procédés destinés à recanaliser des régions (M) à prothèse endovasculaire, à l'intérieur du système vasculaire resténosé. On déplace un corps (20) de cisaillement à l'intérieur de la région à prothèse endovasculaire afin de détacher la matière sténosée d'une enveloppe d'interface définie par la surface intérieure de la prothèse. Généralement, le corps de cisaillement est souple et de dimensions légèrement plus grandes que la prothèse, afin de permettre le retrait sensiblement uniforme de la matière sténosée de toute l'enveloppe d'interface. Le corps de cisaillement peut se présenter sous forme de brosse (96), de rangée hélicoïdale (34), de disques (150) espacés les uns des autres, d'un corps solide compressible ou présenter différentes autres configurations spécifiques.
