The Medtronic Launcher 8Fr ECR45 Coronary Guiding Catheter (REF LA8ECR45) is a single-use, preformed guiding catheter designed to facilitate the introduction and placement of interventional and diagnostic devices into the coronary vasculature. The Launcher family is engineered to deliver consistent backup support, a stable coaxial position and a smooth inner lumen for device delivery.

Key Features
- 8 French outer diameter intended to accommodate larger or multiple interventional devices.
- ECR45 (Extra Backup, 4.5 cm) preformed curve designed for engagement of the left coronary system with enhanced passive support.
- Three-layer shaft construction combining an inner PTFE lumen, stainless steel braid and outer polymer for torque transmission and kink resistance.
- Soft, atraumatic distal tip intended to reduce the risk of vessel trauma during engagement.
- Lubricious inner lumen to support smooth device tracking and exchanges.
- Radiopaque marker characteristics: Not specified in the located sources.

Clinical Applications
- Percutaneous coronary intervention (PCI) requiring strong passive backup support.
- Delivery of balloon catheters, stents and other interventional accessories into the coronary arteries.
- Procedures favoring an extra backup left curve geometry for the left coronary ostium.
- Complex coronary cases where increased lumen size (8Fr) is preferred for device compatibility.
