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 hydrocephalus treatment. # This is a catheter design that is characterized by having a variable number of holes (2) in the different drain rings (3), so that the uniformity of the fluid passage is favored through the catheter (1), while minimizing the possibility of blockage of holes (2) and redistributing the flow is possible in case any of said holes (2) is blocked, thus extending the 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 separation between rings (3), number of holes (2) in each of said rings (3) and rotation thereof.

Finally, in ring 4 the same configuration of ring 3 will be presented by applying the 30 ° rotation and removing two holes (2) so that symmetry is preserved.

10 Ejemplo 2. Se dispone un catéter formado por un tubo hueco (1) de diámetro exterior 2,5 mm y diámetro interior 1,5 mm, el cual dispondrá de un total de 24 orificios (2) y 6 anillos de drenaje (3), siendo el 1 el anillo (3) más próximo a la punta (o extremo cerrado) del catéter (4). La característica principal de este diseño es que los anillos están agrupados dos a dos, formando 10 Example 2. A catheter formed by a hollow tube (1) of 2.5 mm outer diameter and 1.5 mm inner diameter is provided, which will have a total of 24 holes (2) and 6 drain rings (3 ), 1 being the ring (3) closest to the tip (or closed end) of the catheter (4). The main feature of this design is that the rings are grouped two to two, forming

15 franjas (5). Así, los anillos 1 y 2 están agrupados en una primera franja (5), llamada distal, separados 1 mm uno del otro. Los anillos 3 y 4 están agrupados en una franja (5) intermedia, separados 1 mm uno del otro. Finalmente, los anillos 5 y 6 están agrupados en una tercera franja (5), llamada proximal, así mismo separados 1 mm uno del otro. Los dos anillos de la franja (5) distal tienen 6 orificios cada uno, disminuyendo este número a 4 en la franja (5) 15 stripes (5). Thus, rings 1 and 2 are grouped in a first strip (5), called distal, separated 1 mm from each other. Rings 3 and 4 are grouped in an intermediate strip (5), separated 1 mm from each other. Finally, rings 5 and 6 are grouped in a third strip (5), called proximal, also separated 1 mm from each other. The two rings of the distal stripe (5) have 6 holes each, decreasing this number to 4 in the fringe (5)

20 intermedia, y a 2 en la franja (5) proximal. A continuación se describen mediante una tabla las características de cada uno de los anillos de drenaje (3). 20 intermediate, and 2 in the proximal strip (5). The characteristics of each of the drain rings (3) are described below in a table.
