Clinical Trial Summary

Device:

EluNIR Ridaforolimus Eluting Coronary Stent System - (hereafter referred to as EluNIR) 2.25 mm diameter (8 mm, 12 mm, 15 mm, 17 mm, 20 mm, 24 mm, 28 mm and 33 mm length)

Objectives:

To further assess the safety and efficacy of the small diameter (2.25 mm) Ridaforolimus Eluting Stent - EluNIR.

Subject Population:

Subjects who underwent PCI for angina (stable or unstable), silent ischemia (in absence of symptoms a visually estimated target lesion diameter stenosis of ≥70%, a positive non-invasive stress test, or FFR ≤0.80 must be present), NSTEMI, and recent STEMI (>24 hours from initial presentation and stable) with attempted implantation of a 2.25 mm diameter EluNIR stent.

Trial Design and Methods:

This is a prospective, multi-center, single-arm, open-label clinical trial. Clinical follow-up for all patients will be performed at 30 days 6 months, and 1 year after the procedure.

34. Another lesion in a target or non-target vessel (including all side branches) is present that requires or has a high probability of requiring PCI within 12 months after the index procedure.
