The Asahi SheathLess Eaucath Coronary Guiding Catheter (REF G7SC40-0-L100) is a sheathless transradial guiding catheter engineered to facilitate radial access percutaneous coronary interventions. It combines a tapered inner dilator with a hydrophilic-coated guiding catheter, allowing direct insertion into the radial artery without the need for a conventional introducer sheath, helping to reduce arterial trauma while preserving a usable inner lumen for interventional devices.

Key Features
- Sheathless transradial design intended to reduce the effective outer diameter at the access site compared with conventional sheath plus guide combinations.
- 7.5 Fr guiding catheter paired with a tapered inner dilator for smooth vessel entry.
- Hydrophilic coating on the outer surface to support atraumatic advancement through tortuous radial and brachial anatomy.
- Braided shaft construction designed to provide torque response, kink resistance and backup support.
- Large internal lumen intended to accommodate complex PCI device combinations such as dual stents, microcatheters and atherectomy devices.
- Working length and curve configuration as indicated by the reference code; specific dimensions Not specified in the located sources.

Clinical Applications
- Transradial diagnostic and interventional coronary procedures where minimizing access site profile is desirable.
- Complex percutaneous coronary intervention, including bifurcation, chronic total occlusion and calcified lesion treatment requiring strong guide support.
- Cases where a larger functional lumen is required from a small radial artery access.
- Suitability for any specific patient or procedure must be determined by the treating physician in accordance with the manufacturer Instructions for Use.
