Abstract

Una bomba sanguínea giratoria con un sistema de soporte doble de contacto en pivote con un rango de operación de entre aproximadamente 50 ml/min. y aproximadamente 1500 ml/min., en donde la fuerza en el soporte superior es menor que 3 N durante las velocidades de operación de hasta 6000 rpm. La bomba sanguínea giratoria es parte de un sistema de bombeo sanguíneo que incluye uno o unos conductos para sangre, un sistema de control con sensores opcionales y una fuente de energía. Las formas de realización de la presente pueden incluir elementos que están diseñados para aumentar el tiempo que la bomba sanguínea giratoria puede funcionar efectivamente in vivo que incluye materiales de soporte resistentes al desgaste, una placa posterior giratoria para atraer magnéticamente al rotor a fin de reducir las fuerzas de soporte y el desgaste en el pivote de soporte, un tamaño y forma de rotor y una separación de soporte que se combinan para crear un efecto de soporte hidrodinámico y reducir las fuerzas de soporte y el desgaste en el pivote de soporte, mejorar los conductos intravasculares para un aumento de la resistencia a la trombosis, unos manguitos del sitio de inserción del conducto que son resistentes a una infección y unos puertos laterales de conductos que son susceptibles a una inserción fácil de los alambres de guía y los dispositivos médicos basados en catéteres para tratar los conductos y los vasos sanguíneos relacionados a fin de mantener el funcionamiento del sistema de bombeo sanguíneo a lo largo del tiempo. El sistema de bombeo está configurado para conectarse con el sistema vascular de un paciente y bombear la sangre a una velocidad deseada. La presente también se relaciona con un método de uso de un sistema de bombeo sanguíneo para aumentar de forma persistente el diámetro total y el diámetro de lumen de venas y arterias periféricas al aumentar de modo persistente la velocidad de la sangre y la tensión de cizallamiento parietal en una vena o arteria periférica durante un período de tiempo suficiente como para que resulte en un aumento persistente del diámetro total y del diámetro de lumen del vaso. En sistemas de bombeo sanguíneo que se utilizan para aumentar el diámetro total y el diámetro de lumen de un vaso sanguíneo, se monitorea y se ajusta, según sea necesario, el bombeo de la sangre para mantener la velocidad de la sangre y la tensión de cizallamiento parietal en un nivel elevado deseado y la pulsatilidad deseada en el vaso sanguíneo diana con el fin de optimizar la velocidad y el grado de aumento persistente en el diámetro total y al diámetro de lumen del vaso sanguíneo diana. El sistema de bombeo sanguíneo también se puede usar para reducir la hipertensión venosa en un miembro inferior y aumentar la tasa de curación de las úlceras venosas del miembro inferior de pacientes. En sistemas de bombeo sanguíneo que se utilizan para tratar la hipertensión venosa en un miembro, el bombeo de la sangre se monitorea y se ajusta, según sea necesario, para mantener la presión sanguínea venosa deseada en el miembro tratado.
