FDA approval history

In June 1993, the US Food and Drug Administration (FDA) approved the very first coronary stent, Gianturco-Roubin stent.
 Cesar Gianturco, a radiologist, and Gary Roubin, an interventional cardiologist, designed this bare-metal coronary stent, which was manufactured and sold by Cook Inc. The Gianturco-Roubin stent was a balloon-expandable and coil-type stent manufactured using a flat 316 L stainless steel wire coil attached to a single longitudinal strut. The stent length ranged from 12 to 16 mm, and its diameter ranged from 2.5 to 5 mm.

In August 1994, the FDA approved the second coronary stent, the Palmaz-Schatz stent.
Julio C Palmaz, an interventional vascular radiologist, and Richard Schatz, an interventional cardiologist, designed this bare-metal coronary stent, which was manufactured and sold by Cordis. The Palmaz-Schatz stent was a balloon-expandable and slotted-tube type stent manufactured using 316 L stainless steel. Only one stent length (15 mm) was manufactured, but its diameter ranged from 3 to 5 mm.
