The Medtronic Launcher 8Fr ECR40 Coronary Guiding Catheter (REF LA8ECR40) is a single-use guiding catheter designed to deliver and support interventional devices into the coronary vasculature. The Launcher family is engineered around a three-layer construction intended to combine kink resistance, torque response and a smooth inner lumen for device passage during percutaneous coronary intervention (PCI).

Key Features
- 8 French outer diameter for an enlarged inner lumen suited to complex interventional device delivery
- ECR40 (Extra Backup / Curve 4.0) preformed shape intended to provide strong passive support from the contralateral aortic wall
- Three-layer shaft construction: lubricious inner liner, stainless steel braid, and outer polymer jacket for torque transmission and kink resistance
- Soft, atraumatic distal tip designed to reduce the risk of vessel trauma during engagement
- Full-length radiopaque shaft characteristics to aid fluoroscopic visualization
- Single-use, sterile (ethylene oxide) packaging

Clinical Applications
- Percutaneous coronary intervention (PCI) requiring extra backup support
- Delivery of interventional devices, balloons, stents and adjunctive equipment to the coronary ostia
- Procedures targeting the left coronary system where contralateral aortic wall support is desired
- Complex and calcified lesion access where larger 8Fr lumen accommodates multi-device techniques (for example kissing balloon or bifurcation strategies)
