Abstract

LOS BALONES PARA DISPOSITIVOS MEDICOS, EN PARTICULAR PARA LOS CATETERES CON BALON PARA ANGIOPLASTIA, ESTAN HECHOS DE ELASTOMEROS TERMOPLASTICOS DE COPOLIMEROS EN BLOQUE EN EL QUE LOS COPOLIMEROS EN BLOQUE ESTAN HECHOS DE SEGMENTOS DUROS DE POLIESTER O POLIAMIDA Y SEGMENTOS BLANDOS DE POLIETER, LOS SEGMENTOS DUROS DE POLIESTER SON POLIESTERES DE UN ACIDO DICARBOXILICO AROMATICO Y UN DIOL C{SUB,2}-C{SUB,4}; LOS SEGMENTOS DUROS DE POLIAMIDA SON POLIAMIDAS DE ACIDOS CARBOXILICOS C{SUB,6} O SUPERIORES Y DIAMINAS ORGANICAS C{SUB,6} O SUPERIORES O ACIDOS {OE}-AMINO-{AL} ALIFATICOS, Y LOS SEGMENTOS BLANDOS DE POLIETER SON POLIETERES DE DIOLES C{SUB,2}-C{SUB,10}. EL COPOLIMERO EN BLOQUE TIENE UN MODULO DE BAJA FLEXIBILIDAD, ES DECIR, DE MENOS DE 150.000 PSI; EL COPOLIMERO EN BLOQUE TIENE UNA DUREZA MAYOR DE 60, EN LA ESCALA DE SHORE D Y EL PORCENTAJE POR PESO DEL POLIMERO EN BLOQUE ATRIBUIBLE A LOS SEGMENTOS DUROS ESTA, APROXIMADAMENTE, ENTRE 50% Y 95%. LOS POLIMEROS PROPORCIONAN BALONES DE ALTA RESISTENCIA, UNA PARED DELGADA, CONFORMABLES Y SEMICONFORMABLES, LO QUE PRODUCE UN CATETER DE BAJO PERFIL. ESTOS CATETERES TIENEN MUY BUENA PENETRACION INICIAL, UN SEGUIMIENTO SENCILLO Y UNA BUENA PENETRACION DESPUES DE HINCHARLOS POR PRIMERA VEZ.
