An example of Anorad's contribution to our society is its role in the discovery and development of cardio stents. Around 1990, doctors from Advanced Cardiovascular Systems Inc. arrived at Anorad to determine whether Anorad could enable them to produce their Coronary stent invention. Their concept was to manufacture a very small cylindrical tube that could be inserted into patient veins to unblock the flow of blood. The small cylinder contained an inner balloon that would expand by releasing compressed air to allow the blood to flow easily. The difficulty was in manufacturing a very small cylinder designed to collapse to a small size and later expand to a larger size and remain locked in this open state. The manufacture of this type of product was extremely difficult due the very small geometries that are involved. Anwar suggested the use of a CNC (Computerized Numerical Controlled Machine) designed specially by Anorad. This machine used High performance positioning system including a motorized rotary stage and X-Y-Z positioning stages . A laser was used to focus the laser beam on the surface of the cylinder, while the cylinder was rotated & moved to generate the shapes that were proposed by the doctors. This CNC machine was then manufactured by Anorad and used to produce stents that saved many lives. The company Advanced Cardiovascular Systems Inc (now Eli Lilly), obtained several patents which acknowledged the use of the Anorad machines to produce their stents.
