Deployment system (10) to deploy a vascular implant, including the deployment system: a first tube (11) including a lumen (12) and being designed to carry an expandable vascular implant over a distal portion (11a) of the first tube ( 11) in a loaded state, a shell (15) designed to be placed on the vascular implant (20) and which keeps it in a compressed state, where the shell (15) can slide shortly in relation to the vascular implant (20) to release and gradually expanding the vascular implant (20), a coupling element (33) to engage with a distal end (22) of the vascular implant in its loaded state, the coupling element being arranged around and concentrically aligned with the first tube (11 ), where the coupling element is positioned non-slidably between the shell (15) and the first tube (11) near the vascular implant in its loaded state; a tip (13), which is fixedly connected to the first tube (11) at a distal end of the first tube (11), where the tip (13) includes a first proximal end (13a) and a second distal end (13b), the first proximal end (13a) having a hole (14) to loosely accommodate and hold a proximal end (21) of the vascular implant (20) in a charged state, where the tip (13) can slide distally relative to the vascular implant ( 20) to release the proximal end (21) of the vascular implant (20) from the hole (14), characterized in that the deployment system (10) also includes a spring-loaded sealing element (29) which is slidably mounted on the first tube (11) and that it is designed in such a way that, in the loaded state of the vascular implant (20), the sealing element (29) distally contacts the coupling element (33) and that, at the release of the proximal end (21) of the vascular implant of the orifice (14) of the tip (13), the e Slow shutter (29) can engage with the hole (14) and close it.Sistema de despliegue (10) para desplegar un implante vascular, incluyendo el sistema de despliegue: un primer tubo (11) incluyendo un lumen (12) y estando diseña
