Advanced Stent

The stent is normally coated with a 20nm of a drug to reduce the incidence of rejection and to control excessive tissue growth. This coating is depleted in a short - perhaps 2-3 months.

A longer depletion rate would increase the life of the stent and increase the time between replacements. The rendering of the surface of the stent would increase the surface area on which the drugs were contained; further, the receptacles would contain the drugs on the stent for a longer period.

Stents were rendered with smg¿s of a nominal prescription before polishing and being tested subjected to a standard laboratory test. As yet, the optimisation of the rendering parameters has not been achieved.
