The Biosensors International Group (“Biosensors”), Ltd. develops, manufactures and markets innovative medical devices, designed to improve patients’ lives through pioneering medical technology, which pushes the boundaries of innovation.
Biosensors consistently innovates in stent technology. Our initial (DES) system marketed from 2008 onwards was the first to feature a unique abluminally-coated stent with a biodegradable polymer, absorbed synchronously with their proprietary limus1. Our highly lipophilic BA9™ anti-restenotic drug was specifically developed by Biosensors for use on coronary stent applications.
An enhanced version was then launched in Asia, Europe, the Middle East and Africa in May 2010, and had the drug and polymer coated on a highly flexible platform designed to enhance deliverability. Our second generation DES entered the market in 2013 with a further enhanced delivery system. The stent is deployed using an advanced delivery system, featuring a low tip entry profile, longer distal shaft and a reduction in shaft diameter for 5F compatibility2.
Our third generation DES was launched in January 2016, utilizing the same biodegradable polymer and proprietary limus agent on a CoCr stent platform. This platform features a hybrid stent design, combining straight and s-shaped link3 connectors, providing enhanced longitudinal strength while maintaining flexibility. This unique design, combining the cobalt chromium alloy with the proven coating of our proprietary biodegradable polymer and Biolimus A9™, gives us a market leading DES.
The DES family allows treatment of simple and complex coronary lesions4,5,6 and offers unparalleled performance in all coronary lesion types. The excellent technical characteristics are complemented by an extensive clinical research program.
Biosensors' latest innovation is our unique DCS (combination of our proprietary drug Biolimus A9™coated without polymer and carrier). It represents the latest development in Biosensors stent technology and differentiates radically from current DES.
It is a polymer and carrier-free DCS that combines the advantages in efficacy of a DES with the safety of a bare metal stent (BMS).
The combination of a selectively micro-structured surface (SMS) and the rapid transfer of Biosensors own highly lipophilic limus agent Biolimus A9™, makes our DCS the most relevant choice of stent for High Bleeding Risk (HBR) patients who cannot tolerate long dual antiplatelet therapy (DAPT).
These DCS’s unique characteristics, allows neointimal proliferation inhibition like any other DES having various polymer without the potential side effects of long term exposure to a polymer7.
Our DCS is now listed as stent of choice in ESC DAPT guidelines, for 1 month-ultra short DAPT in patients whom longer DAPT regimes poses safety concerns8.
At Biosensors International, we are committed to continuing investment in developing pioneering medical technology and engineering new medical devices, that will further benefit patients. Strongly committed to the values of an Evidence Based Medicine approach, Biosensors was the first company to sponsor a randomized head-to-head comparison against a sirolimus eluting stent in an all comers setting. The LEADERS trial proved non-inferiority on a clinical endpoint against Cypher® Select in 2008 with primary endpoint analysis published in the Lancet9 and continuous positive long term results up to 5 years10.
Supporting our unique Drug Coated Stent (DCS), LEADERS FREE11 is the world’s first prospective, randomized double-blind trial of an active stent, with only 1 month of dual anti-platelet therapy (DAPT) mandated for all patients. The trial was specifically designed for High Bleeding Risk (HBR) patients only and had co-primary endpoints, to confirm that the DCS is as safe as a BMS with superior efficacy. The results were published in the New England Journal of Medicine in October 201511.
Both primary endpoints (safety and efficacy at 1 year) were met with impressive statistical significance and superior safety was achieved.
