The Abbott Sapphire NC24 Coronary Dilatation Catheter (REF 494502612) is a non-compliant, rapid-exchange PTCA balloon catheter engineered for high-pressure post-dilatation and lesion preparation during percutaneous coronary intervention. Configured with a 4.5 mm balloon diameter and a 26 mm working length, it is designed to deliver precise, predictable expansion in calcified, fibrotic, or under-expanded stented segments.

Key Features
Non-compliant balloon material for minimal diameter growth at high inflation pressures.
Rapid-exchange (monorail) shaft configuration for efficient single-operator use.
Low-profile tip geometry intended to support crossing of tight or resistant lesions.
Hydrophilic coating on the distal shaft to facilitate trackability and deliverability.
Two radiopaque markers demarcating the balloon working length under fluoroscopy.
Compatible with 0.014 in (0.36 mm) coronary guidewires.

Clinical Applications
High-pressure post-dilatation of deployed coronary stents to optimize apposition and expansion.
Predilatation and lesion preparation of calcified or resistant native coronary artery stenoses.
Treatment of in-stent restenosis as part of a broader interventional strategy.
Use in saphenous vein bypass graft lesions where applicable to the interventional plan.
