An embolic device deployment system (100) for placing an embolic device at a predetermined site within a vessel comprising: an elongated flexible deployment catheter (2) having a first light (4) extending therethrough. and which has the proximal (3) and distal (5) ends； a notch section (6) arranged in the first light of the catheter and forming a second light； an embolic device (16) having a retaining ring (20) at the proximal end thereof； a coupling element (8) partially disposed in the second light, comprising: a distal loop (12) extending through the retaining ring； and a proximal loop (10) that extends into the first light； and an elongated separation element (14) that is slidably disposed within the first light of the deployment catheter and disposed through the proximal and distal loops, comprising a protuberance (24) of separation element disposed in the element of separation between the proximal and distal loops； wherein when the separation element is disposed within the distal loop and the distal loop is disposed within the retaining ring, the embolic device is in an engaged position, in which when the separation element is pulled proximally, the element Separation is removed from the distal loop and the protrusion of the separation element comes into contact with the proximal loop and proximally displaces the engagement element to help disengage the distal loop of the retaining ring to thereby release the embolic device.Un sistema de despliegue de dispositivo embólico (100) para colocar un dispositivo embólico en un sitio predeterminado dentro de un vaso que comprende: un catéter de despliegue flexible alargado (2) que tiene una primera luz (4) que se extiende a través del mismo y que tiene los extremos proximal (3) y distal (5)； una sección de muesca (6) dispuesta en la primera luz del catéter y formando una segunda luz； un dispositivo embólico (16) que tiene un anillo de retención (20) en el extremo proximal del mismo； un elemento de enganche (8) parcial
