Document Type and Number:
Japanese Patent JP2931010
Kind Code:
B2
Abstract:
The intravascular stent intended for implantation in a stenotic area or zone of obstruction of a blood vessel consists of a flat sheet (1) which is perforated to form a kind of a reticulated or lattice type structure with undeformable links (2) and made of malleable material. Said sheet (1) is temporarily rolled up and locked in a spiral with a relatively small diameter (d) on a deflated angioplasty balloon (6) mounted on the end of a catheter (7) and is held in said rolled-up state by a tie (8) laced into overlapping links. Once the device is in place in the restricted area of the blood vessel to be treated and after tie (8) is removed, the rolled sheet (1) is expanded to a desired diameter (D) by inflating balloon (6) and is then held in this expanded state by integrated holding flaps (5) which, after the balloon is deflated, extend through the links and engage the edges thereof under the pressure of the vessel.
