Title (EN) INTRAVASCULAR CATHETER HAVING COMBINED IMAGING ABRASION HEAD
(FR) CATHETERS INTRAVASCULAIRES DOTES D'UNE TETE D'IMAGERIE ET D'ABRASION COMBINEE
Abstract:
(EN) Front-end and side-on intravascular catheters are described that comprise an abrasive head (126) contained substantially within a housing (120). Aspiration means and flushing means (128) are connected to the region of grinding to remove dislodged debris. A preferred embodiment has the abrasive surface of a rotatable head comprised of diamond powder. Another preferred embodiment has an ultrasonic transducer (660) affixed to the head to permit transluminal imaging of the site of occlusion.
(FR) Cathéters intravasculaires de types frontal et latéral comprenant une tête abrasive (126) contenue à l'intérieur d'un logement (120). Un moyen d'aspiration et un moyen d'évacuation (128) sont connectés à la région de meulage afin d'éliminer les résidus délogés. Selon un mode de réalisation préféré, la surface abrasive d'une tête rotative se compose d'une poudre de diamant. Selon un autre mode de réalisation préféré, un transducteur ultrasonique (660) est fixé à la tête afin de permettre une imagerie transluminale du site d'occlusion.
