The evolution of the coronary stent market, like most medical device markets, has been driven by manufacturers focused on expanding the use of coronary stents into new caseload as well as penetrating the market shares of competitors.
Clinicians, for their turn as gatekeepers in this effort, are guided in the adoption of stent technologies by the availability of clinical evidence supporting expansion of stent use to patients whose coronary heart disease might otherwise be addressed by coronary artery bypass graft (CABG) surgery, with their selection of the specific stent used determined (to the extent that price is not an overriding attribute) by how well each stent’s clinical data stands up under scrutiny of possible clinical complications.
Manufacturers then take a hard view of both cost and complication rates. Below are shown the potential complications ensuing from stent implantation and which have therefore become a focus of stent technology development:
