How has the constitution and design of stents changed over the years? What kind of research is going on in stents?
From heavier designed stents in earlier days, to more sleeker stents now with much less metal to artery surface ratio without compromising much on radial strength, the designs have changed majorly. Even the stent composition has undergone major transformation from stainless steel to nitinol, to tantalum, platinium and cobalt cromium stents. Then we had bioactive stents like heparin-coated to phosphotidyl-coated, carbon-coated (to make them more inert) to the present titanium-nitride-oxide-coated stents. Finally, we have the first generation polymer-based DES to more recent DES without polymer. And now, research is being conducted on bioabsorbable stents. Robotic Angioplasty What is the main difference between Robotic PCI and manual PCI? The main difference between remote control robotic PCI and traditional hand held device manipulation is that the physician operates from a workstation rather than at the bedside. There is no difference felt or realized by the patient with robotic operat
