Abstract
Un dispositivo para desplegar implantes que se autoexpanden radialmente y otros implantes radialmente expandibles, incluye un catéter interno, un catéter externo que circunda al catéter interno, y un implante de estenosis tubular que retiene la funda formada a partir de una membrana de arrollamiento; la funda está doblada sobre si misma para proporcionar una envoltura interna de funda sujeta al catéter interno, y una envoltura externa de funda sujeta al catéter externo; las envolturas de la funda se extienden a lo largo de y circundan a un implante de estenosis que se auto-expande radialmente, para mantener el implante de estenosis distalmente del catéter interno y en un estado radialmente comprimido, axialmente, axialmente alargado; distalmente del implante de estenosis, las envolturas interna y externa de la funda convergen y se estrechan en direccion distal para definir una extremidad distal ahusada. Para liberar el implante de estenosis, el catéter externo se mueve proximalmente para enrollar la membrana fuera de su relacion circundante con respecto al implante de estenosis, mientras que el implante de estenosis se auto-expande progresivamente en sentido radial, comenzando por el extremo distal; cuando se ha retraído completamente tras la liberacion del implante de estenosis, la funda circunda una region distal del catéter interno, y puede proporcionar una envoltura protectora entre el tejido arterial y un balon de dilatacion soportado a lo largo de la region distal; como alternativa, un implante de estenosis formado a partir de un metal de recuperacion puede ser deformado plásticamente hacia un estado de radio reducido para su suministro, lo que facilita el uso de una funda más flexible de retencion del implante de estenosis. Otra alternativa incluye asegurar la funda proximalmente al balon de dilatacion, de modo que la retraccion de la funda deje el balon de dilatacion al descubierto, en vez de cubierto por la funda.
