The Integrity Coronary Stent System (Medtronic Vascular, CA, USA) is a low-profile, open-cell, cobalt-chromium-alloy advanced bare-metal iteration of the well-known Driver/Micro-Driver Coronary Stent System (Medtronic Vascular). The Integrity stent is made with a process called continuous sinusoid technology. This process allows stent construction via wrapping a single thin strand of wire around a mandrel in a sinusoid configuration, with laser fusion of adjacent crowns. The wire-forming process and fusion pattern provide the stent with a continuous preferential bending plane, intended to allow easier access to, and smoother tracking within, distal and tortuous vessels while radial strength is maintained. Continuous sinusoid technology represents innovation in the design of stent platforms and will provide a future stent platform for newer technology, including drug-eluting stent platforms, drug-filled stents and core wire stents.
Integrity 冠状动脉支架系统（美敦力血管，加利福尼亚，美国）是一种低轮廓、开腔、钴铬合金的先进裸金属迭代版本，是著名的 Driver/Micro-Driver 冠状动脉支架系统（美敦力血管）。Integrity 支架是通过一种称为连续正弦技术的工艺制造的。该工艺通过在正弦形状的芯轴上缠绕一根细金属丝来构建支架，并用激光融合相邻的冠部。金属丝成型工艺和融合模式为支架提供了一个连续的优先弯曲平面，旨在允许更容易地进入和更顺畅地跟踪远端和迂曲的血管，同时保持径向强度。连续正弦技术代表了支架平台设计的创新，将为包括药物洗脱支架平台、药物填充支架和中心丝支架在内的新技术提供未来的支架平台。
