Stent System for Small Vessels

There are currently no cobalt chromium drug-eluting stents on the market, according to DISA Vascular Ltd. (Cape Town, South Africa), which developed the new stents.

Similar to the large-vessel ChromoFlex, the micro-stent has ultra-thin struts. This feature has been shown to reduce stenosis dramatically in various independent clinical studies. This is due to the use of a special cobalt chromium alloy that offers numerous advantages over conventional stainless steel because of its increased strength and radiographic visibility, states DISA Vascular.

"Since the launch of the ChromoFlex stent in Europe and elsewhere, this product has performed extremely well,” said Dr. Starke, CEO of DISA Vascular. Dr. Starke feels confident that properly designed cobalt chromium stents used for local drug delivery, such as the ChromoFlex and ChromoFlex micro-stent, will be markedly easier to deliver and have better clinical outcomes than the stainless steel drug-eluting versions currently available.

According to Dr. Starke, the new micro-stent, for vessels 2.5-3.0 mm in diameter, will have even better deliverability features than the large-vessel version because of its extremely low profile and high flexibility. Stents for smaller vessels are in high demand in Asian and Middle Eastern markets where DISA Vascular has strong market interest.
