Coronary Artery Bypass Graft (CABG) is most common type of heart surgery that is performed to treat people suffering from severe angina and coronary artery heart disease. In coronary heart disease, a plaque is formed inside the coronary artery that carries oxygenated blood to myocardium. As the plaque becomes harder over the time, it narrows down the artery and subsequently causes reduced blood flow to heart leading to chest pain called angina. In CABG, a healthy artery or vein from elsewhere in the body is grafted to blocked coronary artery that facilitates the flow of oxygenated blood to heart muscles. Depending on the number of coronary arteries bypassed, the surgery is referred as single bypass, double bypass, triple bypass and quadruple bypass. Usually, there are two different methods to perform CABG namely on-pump CABG and off-pump CABG. Some minimally invasive coronary artery bypass (MIDCAB) surgeries are also performed such as endoscopic or thoracoscopic and robotic assisted surgery that include smaller incision, less bleeding, low risk of infection and reduced recovery time. Some of the commercially available devices used in CABG are OPTrac STILLSITE Stabilizer by Heartport, Ultima OPCAB system by Guidant and OCTOPUS 2+ Tissue Stabilization System by Medtronics. Some of the prominent vendors operating in this market are Sorin Group, Heratport, MAQUET, Guidant, Medtronic and Terumo.
