Abstract

Catéter para tratamiento de la hidrocefalia. Se trata de un diseño de catéter que se caracteriza por disponer de un número variable de orificios (2) en los distintos anillos de drenaje (3), de modo que se favorece la uniformidad del paso del fluido a través del catéter (1), a la vez que se minimiza la posibilidad de obstrucción de orificios (2) y se posibilita la redistribución del flujo en caso de que alguno de dichos orificios (2) se obstruya, alargando así la vida útil del dispositivo. Se describe asimismo dos posibles configuraciones de reparto de orificios (2) en base a unas pautas descritas para la distribución de orificios (2) en anillos (3), diferenciadas en cuanto a separación entre anillos (3), número de orificios (2) en cada uno de dichos anillos (3) y rotación de éstos.Catheter for treatment of hydrocephalus. It is a catheter design that is characterized by having a variable number of holes (2) in the different drainage rings (3), so that the uniformity of the passage of the fluid through the catheter (1) is favored. At the same time, the possibility of clogging of orifices (2) is minimized and redistribution of the flow is made possible in the event that any of said orifices (2) become obstructed, thus extending the useful life of the device. Two possible hole distribution configurations (2) are also described based on some guidelines described for the distribution of holes (2) in rings (3), differentiated in terms of spacing between rings (3), number of holes (2) in each of said rings (3) and rotation thereof.
