Abstract

UN ATEROTOMA DE CATETER (10) Y METODO PARA SU USO PARA LLEVAR A CABO UNA ATERECTOMIA PARCIAL EN UNA ARTERIA Y ASI ALARGAR EL LUMEN PARA QUE QUEDE DISPONIBLE DE MANERA EFECTIVA PARA EL FLUJO SANGUINEO A TRAVES DE LA ARTERIA. HAY VARIAS CUCHILLAS (34) MONTADAS EN UN EXTREMO DISTAL DE UN CATETER (30), EN UNA CONFIGURACION DE CESTA HELICOIDAL Y SEPARADAS ANGULARMENTE ENTRE SI ALREDEDOR DE LOS EXTREMOS ASOCIADOS DE DOS REVESTIMIENTOS CONCENTRICOS (12, 14) DE TAL MODO QUE EL MOVIMIENTO RELATIVO GIRATORIO Y LONGITUDINAL DE LOS REVESTIMIENTOS ARQUEA SELECTIVAMENTE LAS CUCHILLAS HACIA AFUERA A UNA POSICION DE CORTADO Y TIRA DE LAS CUCHILLAS A UNA POSICION DE CORTADO O TIRA DE LAS CUCHILLAS PARA QUE QUEDEN PLANAS, ALINEADAS CON LOS REVESTIMIENTOS. LAS CUCHILLAS (34) TIENEN UNOS BORDES CORTANTES AFILADOS (44) QUE SE EXTIENDEN HELICOIDALMENTE Y SE DIRIGEN HACIA EL EXTREMO PROXIMO DEL CATETER CUANDO LAS CUCHILLAS ESTAN ARQUEADAS. LA EXTRACCION PARCIAL DEL ATEROMA SE LLEVA A CABO TIRANDO MANUALMENTE DE LA CUCHILLA DE CESTA PASADO UN ATEROMA CON LAS CUCHILLAS (34) EN SUS POSICIONES DE CORTE ARQUEADAS HACIA AFUERA, SIENDO LA VELOCIDAD, FUERZA Y CANTIDAD DE EXPANSION DE LAS CUCHILLAS DETERMINADA POR EL OPERADOR.
