SINOTECH+ Sirolimus-Eluting Coronary Stent

Overview

The SINOTECH+ sirolimus-eluting stent pairs a thin-walled cobalt-chromium (Co-Cr) scaffold with a waved open-cell geometry and a sirolimus coating (1.4 µg/mm²). After delivery and balloon expansion at the lesion, the drug coating limits excessive tissue growth (hyperplasia) to help prevent in-stent restenosis. For use only by physicians experienced in PTCA and stent implantation.

Key features

• Cobalt-chromium (Co-Cr) platform with 70 μm wall thickness
• Sirolimus coating, 1.4 µg/mm² drug content
• Waved open-cell structure for uniform expansion and vessel adaptation
• Delivered pre-mounted on a balloon catheter
• Six diameters (2.25–4.00 mm) and eight lengths (8–42 mm)

Clinical applications

• Percutaneous Transluminal Coronary Angioplasty (PTCA)
• Permanent dilation of stenotic native coronary arteries
• Reduction of in-stent restenosis risk

Intended use

Cardiac surgery. The SINOTECH+ sirolimus-eluting coronary stent system is indicated for Percutaneous Transluminal Coronary Angioplasty (PTCA) — the permanent dilation of the stenotic portion of a native coronary artery by placement of a coronary stent, to improve myocardial perfusion. For use only by physicians with significant experience in PTCA and stent-implantation procedures.

How it's used

Coronary stents are cylindrical, drug-coated mesh frameworks inserted into narrowed sections of an artery to expand them. Cholesterol plaque can accumulate and reduce — or completely block — blood flow, starving the heart muscle of oxygen. The stent is delivered folded over a balloon catheter to the lesion and expanded, widening the vessel and restoring flow; the antiproliferative drug coating then treats the artery wall and helps prevent excessive tissue regrowth (restenosis).
