Sirolimus eluting cobalt chromium coronary stent with fully bio-degradable matrix for drug release up to six weeks Of course Made In Germany


A drug eluting stent with a bio degradable, abluminal coating of a polymer carrier loaded with 1.4 µg sirolimus per sqmm stent surface. Pre-mounted stent onto a double lumen PTCA catheter for rapid exchange use with a semi-compliant balloon, two radio-opaque markers, proximal and distal. 140 cm working length, 25 cm from tip. Nominal inflation pressure at 8 atm, Rated burst inflation pressure at 16 atm / 14 atm for 3.50 mm @ L > 35 mm and for 4.00 mm @ L > 30 mm. 0.035" average crossing profile. 0.064" min. guiding catheter I.D. 0.014" max. guide wire O.D.

Drug stent technology par excellence

STENT DESIGN AND TECHNOLOGY OSIRACR stents are made from L605 cobalt chromium Alloy, with smooth electropolish surface (SES). The stents are designed as slotted tube, open cell devices with 3 interlinks per segment and 6 zigzag elements per ring element. Therefore they are highly flexible with an extra very low crossing profile (0.035" / 0.90 mm) for excellent lesion crossing. OSIRACR products are Pre-mounted stent Systems onto a double lumen rapid exchange semi-compliant balloon catheter. Mounted with special crimping methods, results an excellent push-ability. The delivery system has two radio opaque markers (proximal and distal) and a 140 cm working length, 25 cm from tip. The balloon length is max. 0.5 mm longer than the stent. Each stent is tested with a unique method (world wide patents pending) to provide the most higher security against slippery. The SDS has a nominal inflation pressure at 8 atm, and a Rated burst inflation pressure at 16 atm (14 atm for 3.50 mm @ L > 35 mm and for 4.00 mm @ L > 30 mm). A implantation requires a 0.064" min. guiding catheter I.D. and a 0.014" max. guide wire O.D.

Made in Germany

your cath lab needs
OSIRACR stents are coated with a mixture of a bio-degradable matrix and sirolimus drug. The coating is abluminal, what's means, almost 95% of the drug is released there,were is needed.The elution begins immediately after implantation . 6 weeks after the operation is done, the drug is consumed and the elution stops automatically.
A bare metal stent remains in the body, with no side effects like a late thrombosis.
