A Prospective, Multi-center, Single-blind, Randomized (1:1), Non-inferiority Study Comparing Clinical Outcomes of the Virtue® Sirolimus AngioInfusion™ Balloon (SAB) to the AGENT™ Paclitaxel Drug-Coated Balloon (DCB) in the Treatment of Coronary Artery In-stent Restenosis (ISR).

Inclusion Criteria: * In-stent restenosis (one or two stent layers) in a lesion previously treated with drug- eluting (DES) or bare metal stents (BMS) in a native coronary artery. * The target lesion is in a vessel with a reference vessel diameter ≥ 2.0 mm and ≤ 4.0 mm by visual assessment. * The subject has only one critical ISR lesion. * The subject may have one other critical lesion in a non-target vessel that must be treated before the Target Lesion (TL). * Target lesion length must be ≤ 26 mm and must be completely coverable by only one Virtue® or AGENT™ balloon. The balloon can extend u…
