Positioning system for placing and deploying stents that have proximal apexes, comprising: a light (620) of guidewire having a distal end and an inner part that extends along a longitudinal axis； an apex release light (640) having a distal end and which is slidably arranged around said light (620) of guide wire； an apex capture device (634), comprising: a distal apex head (636) fixedly connected to said distal end of said guide wire light (620), said distal apex head (636) having: radii comprising external circumferential surfaces, and a distal surface (639) oriented in a distal direction； and a proximal apex body (638) fixedly connected to said distal end of said apex release light (640) and having: fingers extending towards said distal apex head (636) in a distal direction and which they form teeth to engage the distal apex head to capture proximal apexes of a bare stent (30) between the distal apex head and the proximal apex body (638), and disengage the distal apex head with the relative movement of light (640) of apex release and light (620) of guidewire, in which the radii of the distal apex head (636) slide into the fingers of the proximal apex body (638) as they move parts towards each other, preventing the distal surface (639) that the proximal apexes (32) slide along with the proximal apex body (638), thereby guaranteeing the automatic release of the captured proximal apexes (32).Sistema de colocación para colocar y desplegar endoprótesis que tienen ápices proximales, que comprende: una luz (620) de hilo guía que tiene un extremo distal y una parte interior que se extiende a lo largo de un eje longitudinal； una luz (640) de liberación de ápices que tiene un extremo distal y que está dispuesta de manera deslizable alrededor de dicha luz (620) de hilo guía； un dispositivo (634) de captura de ápices, que comprende: un cabezal (636) de ápice distal conectado de manera fija a dicho extremo distal de dicha luz (620) de hilo guía, teniendo dicho cabezal (636) de
