The Abbott NC TREK NEO Coronary Dilatation Catheter (REF 1400550-20) is a non-compliant rapid-exchange balloon catheter designed for predictable high-pressure inflation during percutaneous coronary interventions. This 5.5 mm x 20 mm configuration is intended for post-dilatation and lesion preparation in larger coronary vessels and selected anatomies where consistent balloon diameter under pressure is critical.

Key Features
Non-compliant balloon material engineered for minimal diameter growth at high inflation pressures.
Rapid-exchange (Rx) shaft design to support single-operator workflow.
Low-profile balloon and tapered tip to facilitate crossing of tight or calcified lesions.
Hydrophilic coating on the distal shaft to support trackability and deliverability.
Dual-marker radiopaque bands to assist accurate balloon placement under fluoroscopy.
Compatible with 0.014 in guidewires and standard guide catheters per the manufacturer IFU.

Clinical Applications
Post-dilatation and optimization of deployed coronary stents.
High-pressure dilatation of resistant or fibrotic coronary lesions.
Lesion preparation in larger-caliber coronary segments.
Adjunctive use during complex PCI procedures where controlled, non-compliant inflation is required.
