The Boston Scientific THREADER Monorail Micro-Dilatation Catheter (REF H7493926912120) is a low-profile rapid-exchange balloon catheter engineered to facilitate lesion access and micro-dilatation in complex coronary interventions. With a 1.2 mm balloon diameter, a 12 mm balloon length, and a 150 cm working length, it is designed to navigate tortuous vessels and tight, calcified or chronically occluded segments where conventional balloons may not track or cross.
Key Features
- Monorail (rapid-exchange) shaft configuration for efficient single-operator catheter exchanges
- Ultra-low crossing profile intended to support crossing of tight, fibrotic or calcified lesions
- 1.2 mm semi-compliant balloon for controlled micro-dilatation and pre-dilatation
- 12 mm balloon working length for focal lesion treatment
- 150 cm usable shaft length compatible with standard coronary guide catheters
- Hydrophilic distal segment to enhance trackability and pushability (per manufacturer literature)
- Radiopaque marker(s) to aid fluoroscopic balloon positioning
- 0.014 in (0.36 mm) guidewire compatibility
Clinical Applications
- Pre-dilatation of de novo or restenotic coronary lesions prior to stent delivery
- Support for crossing tight, calcified or tortuous coronary segments
- Adjunctive use in chronic total occlusion (CTO) and complex PCI workflows
- Facilitation of microcatheter or stent delivery in difficult anatomy
- Lesion preparation in small-vessel coronary disease
