Abstract

La presente invención se relaciona con un procedimiento para formar una punta biselada sobre un catéter que comprende: a) montar una preforma de catéter sobre un mandril; b) proveer un molde que tiene una superficie interna ahusada predeterminada, y una zona que tiene una porción estrecha entre dicha superficie interna y una zona de recolección; c) calentar dicho molde; d) mover la preforma de catéter y el mandril en relación con dicho molde para hacer que la preforma de catéter sea calentada y fluya a través de dicha porción estrecha y forme rebaba sobre un lado de dicha porción estrecha opuesto a la superficie interna ahusada; e) permitir que la rebaba se enfríe lo suficiente para evitar que una porción substancial de dicha rebaba regrese a través de la porción estrecha; y f) separar el molde y mandril para hacer que dicha preforma de catéter se desprenda en la construcción para separar la rebaba del resto de la preforma del catéter.
