<p>A tubular cylindrical prosthetic device (50), in other words an implantable metallic stent for grafting into the human body, presenting an intraluminal delivering system and being expandable into a second shape by a balloon catheter (25), associated to a drug releasing biological outer coating (32), providing the function of slow and controlled liberation of antiproliferative and antithrombotic drugs, which are stores in various microcapsules (36), said microcapsules (36) being dispersed inside a slow releasing matrix (35). The device (50) presents a limited number of rings (45), formed by transversal rods (29). The transversal rods (29) are connected by longitudinal ligaments (12), disposed along the longitudinal axis of the prosthesis, in an intercepted way. The ligaments (12) are interconnected to the wire mesh tube with spheres of radioactive components (10). The intraluminal delivering system comprises a conventional floppy guidewire (17) for delivering the outer coating (32) in the body passageway, and a balloon catheter (25) attached to the prosthesis in a collapsed state thereon.</p> |
