Abstract:
A device for the implantation of expandable stents in a vascular vessel, allowing for temporary protection of downstream organs, comprising:a central stent pusher part surrounded by a stent-releasing part, said central stent pusher part being provided with an axial lumen bearing at its distal end an atraumatic tip,a stent loading cavity designed to contain a stent in a radially contracted state extending near the distal end of the stent pusher part,whereinsaid atraumatic tip is prolonged by a tip balloon part comprising an inflatable occlusive balloon hermetically connected via the axial lumen to an injector adapted to feed said balloon with a physiologically acceptable fluid at predetermined rates, anda fluid-releasing section extends at a proximal side of the occlusive balloon, said releasing section being able to release the fluid from the balloon into an upstream section of the vessel when the pressure of said fluid reaches a predetermined level.
