The Boston Scientific NC Quantum Apex PTCA Dilatation Catheter (REF H7493912406200) is a non-compliant rapid exchange coronary balloon catheter configured with a 2.0 mm diameter x 6 mm length balloon. It is engineered to deliver high-pressure, uniform inflation for post-dilatation of deployed coronary stents and treatment of resistant stenotic lesions in the coronary vasculature.

Key Features
- Non-compliant balloon material designed to maintain diameter at high pressures for predictable lesion and stent expansion.
- Rapid exchange (Monorail) catheter design to facilitate single-operator use over a 0.014 in guidewire.
- Low crossing profile and hydrophilic coating on the distal shaft intended to support deliverability through tortuous or tight anatomy.
- Bi-segment shaft construction engineered to balance pushability and trackability.
- Two radiopaque markers for fluoroscopic balloon positioning.
- Nominal and rated burst pressures per the manufacturer's compliance chart (Not specified in the located sources for exact kPa values in this response).

Clinical Applications
- Post-dilatation and optimization of deployed coronary stents to improve stent apposition and expansion.
- Dilatation of resistant, calcified, or under-expanded coronary lesions.
- Use in percutaneous transluminal coronary angioplasty (PTCA) procedures where high-pressure, non-compliant inflation is indicated by the treating physician.
