ABSTRACT:
The intravascular stent intended for implantation in a stenotic area or zone of obstruction of a blood vessel consists of a flat sheet which is perforated to form a kind of a reticulated or lattice type structure with undeformable links and made of malleable material. Said sheet is temporarily rolled up and locked in a spiral with a relatively small diameter (d) on a deflated angioplasty balloon mounted on the end of a catheter and is held in said rolled-up state by a tie laced into overlapping links. Once the device is in place in the restricted area of the blood vessel to be treated and after tie is removed, the rolled sheet is expanded to a desired diameter (D) by inflating balloon and is then held in this expanded state by integrated holding flaps which, after the balloon is deflated, extend through the links and engage the edges thereof under the pressure of the vessel.
