ESI History
In 1999, ESI attempted to breech the cardiovascular market by developing a novel, bare-metal coronary stent created using our unique electroforming process.
Before we could bring that product to market, however, the medical industry shifted to the use of drug-eluting stents. In turn, ESI responded by developing an electroformed, inert-metal sponge designed for drug-elution.
Further adapting to changing market demands, ESI tailored our electroformed coronary stents for neurovascular applications by developing an aneurysm stent with a higher surface density: the pleated stent. Although effective in the treatment of wide-necked and fusiform aneurysms, the pleated stent is limited in that it will not properly treat aneurysms at bifurcations.
As a result, ESI developed a complimentary new product, the ESI O-cluder, to overcome the limitations of the pleated stent. As a complete aneurysm occlusion package, the ESI O-cluder and pleated stent treat aneurysms (including wide-necked and fusiform aneurysms and aneurysms occurring at a bifurcation) more efficiently and effectively than current methods.
