Abstract

El dispositivo de oclusión vascular de doble cono de la presente invención consiste en una doble espiral, una de las espirales en forma de doble cono y la otra preferiblemente con fibras de poliéster a lo largo de su longitud, en donde el diámetro menor de la espiral de doble cono está en el centro del dispositivo (Figura 1) para permitir la formación de un trombo e impedir el paso del flujo sanguíneo a través del DAP una vez implantado el dispositivo.El dispositivo es preferiblemente fabricado con nitinol, una aleación de níquel y titanio de amplio uso en la industria médica. El nitinol es comúnmente conocido como el material de ingeniería en la industria médica gracias a sus propiedades elásticas y de memoria de forma, que permiten que los dispositivos elaborados con este material puedan llevarse a sitios anatómicos remotos a través de catéteres u otros sistemas de introducción.Las diferencias principales con los dispositivos anteriores son, en primer lugar, que la presente invención es una sola pieza de doble cono elaborada de nitinol; en segundo lugar, que se pueden adicionar fibras de poliéster entre los anillos de una de sus espirales. Las fibras de poliéster cumplen la misma función del balón de látex del DBC de generar el trombo e impedir el paso del flujo sanguíneo a través del DAP.El dispositivo de doble cono (DCN) de la presente invención ocluye completamente el DAP sin dejar corto circuito residual y ayuda a la epitelización de los extremos del Ductus. Hasta el momento no se han reportado datos de hemólisis producida con dispositivos fabricados con nitinol.The double cone vascular occlusion device of the present invention consists of a double spiral, one of the spirals in the form of a double cone and the other preferably with polyester fibers along its length, where the smaller diameter of the spiral Double cone is in the center of the device (Figure 1) to allow the formation of a thrombus and prevent the passage of blood flow through the DAP once the device is implanted.The device is preferably made of nitinol, a nickel alloy and Titanium widely used in the medical industry. Nitinol is commonly known as the engineering material in the medical industry thanks to its elastic and shape memory properties, which allow devices made with this material to be taken to remote anatomical sites through catheters or other introduction systems. The main differences with the above devices are, first, that the present invention is a single piece of double cone made of nitinol; secondly, that polyester fibers can be added between the rings of one of its spirals. The polyester fibers fulfill the same function of the DBC latex balloon of generating the thrombus and preventing the passage of blood flow through the DAP. The double cone device (DCN) of the present invention completely occludes the DAP without leaving a short circuit residual and helps epithelialize the ends of the Ductus. So far no data on hemolysis produced with devices manufactured with nitinol have been reported.
