The Integrity bare-metal stent made by continuous sinusoid technology.

The Integrity (R) 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 (R)/Micro-Driver (TM) 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.
