The NC Quantum Apex 3.75 mm × 15 mm monorail PTCA dilation catheter is designed as a “post‑dilatation” balloon tool, optimized for use after stent deployment to ensure full stent expansion and optimal vessel wall apposition. Its monorail design (rapid-exchange) allows more efficient handling in the coronary setting, reducing the amount of guidewire that must be manipulated and improving procedural flow in complex lesion environments. The 3.75 mm balloon size offers a moderate diameter suitable for many coronary vessels needing post-dilation, and the 15 mm length is tailored for focal stent segments.

One of its distinguishing features is its enhanced mechanical flexibility and deliverability: Boston Scientific claims that the Quantum Apex series delivers 27 % better distal-end flexibility, 26 % improved tip flexibility, 23 % less tip catch, and 23 % better recrossing performance compared to previous generation designs. These refinements help the catheter negotiate tortuous coronary anatomy, cross residual stenosis within a stent, and re-enter the lumen distal to the lesion more reliably. The use of platinum‑iridium marker bands ensures good radiographic visibility of balloon position, aiding precise alignment during inflation.

In clinical practice, the 12 ATM rated burst pressure offers a safety margin when performing high-pressure post-dilatation, and the low balloon growth ensures that the device maintains dimensional integrity under pressure, minimizing risk of overexpansion beyond intended limits. The catheter is appropriate for both native coronary lesions and stent “touch-up” work, subject to anatomical suitability and operator judgment. As with all PTCA balloons, it must be used in settings with appropriate backup (e.g. surgical coronary bypass capability) due to the inherent risks of coronary interventions such as vessel dissection, perforation, or abrupt closure.
