Abstract

UN BALON DE DILATACION CON AL MENOS UNA RANURA HELICOIDAL DISPUESTA EN AL MENOS UNA PARTE DE LA SUPERFICIE DE DILATACION DEL BALON DE DILATACION, QUE ESTA MONTADO SOBRE EL EXTREMO DISTAL DEL EJE DEL CATETER. SE PUEDEN PROPORCIONAR MULTIPLES RANURAS HELICOIDALES EN EL BALON DE DILATACION, QUE SE EXTENDE PARALELAMENTE ENTRE SI, U OPUESTAMENTE ENTRE SI, EN LA SUPERFICIE DE DILATACION. CADA RANURA DE DILATACION POSEE UNA ALTURA, ANCHURA Y PROFUNDIDAD. DE ACUERDO CON UN ASPECTO DE LA INVENCION, LA ALTURA, ANCHURA Y PROFUNDIDAD DE LA RANURA HELICOIDAL, ADEMAS DEL NUMERO DE RANURAS, SE SELECCIONAN PARA PERMITIR LA PERFUSION SANGUINEA A TRAVES DEL CATETER DE DILATACION CUANDO EL BALON DE DILATACION ESTA INFLADO EN UN VASO SANGUINEO. DE ACUERDO CON OTRO ASPECTO DE LA INVENCION, LA SELECCION DE LA ALTURA, ANCHURA Y PROFUNDIDAD DE LA RANURA HELICOIDAL ASI COMO EL NUMERO DE RANURAS SE REALIZA DE MANERA QUE EL BALON DE DILATACION SE CONFORME A UN VASO SANGUINEO TORTUOSO, Y NO ESTIRE EL VASO SANGUINEO DURANTE LA DILATACION. DE ACUERDO CON OTRO ASPECTO DE LA INVENCION, LA SELECCION DE LA ALTURA, ANCHURA Y PROFUNDIDAD DE LA RANURA HELICOIDAL SE REALIZA PARA CONTROLAR LA ADAPTACION DIAMETRICA DEL BALON. LA SELECCION DE LA ALTURA, ANCHURA Y PROFUNDIDAD DE LA RANURA HELICOIDAL PUEDE REALIZARSE PARA PROPORCIONAR TANTO LA CONFORMACION A LA FORMA DEL VASO SANGUINEO TORTUOSO COMO LA ADAPTACION DIAMETRICA. EL SURCO HELICOIDAL TAMBIEN PERMITE QUE EL BALON SE DESHINCHE SIN "DOBLECES", ES DECIR, FORMANDO PLIEGUES PLANOS INDESEADOS QUE SE EXTIENDAN HACIA FUERA DEL RESTO DEL CATETER.
