The Medtronic Launcher 7Fr ECR40 Coronary Guiding Catheter (REF LA7ECR40) is a single-use coronary guiding catheter designed to deliver reliable backup support, consistent torque transmission, and a smooth atraumatic tip for selective engagement of the coronary ostia. The Launcher family is widely used in percutaneous coronary intervention (PCI) where catheter stability and lumen integrity are critical for device delivery.

Key Features
Three-layer shaft construction designed for kink resistance and 1:1 torque response.
Stainless steel braid reinforcement intended to support deliverability of interventional devices.
Soft, atraumatic distal tip designed to reduce vessel trauma during ostial engagement.
Hydrophilic-compatible inner lumen designed for smooth device passage.
Radiopaque marker and tip configuration to aid fluoroscopic visualization.
7 French (Fr) outer diameter with ECR40 curve geometry.

Clinical Applications
Selective cannulation of coronary ostia during diagnostic angiography and PCI.
Delivery of interventional devices including balloons, stents, and guidewires.
Procedures requiring extra backup support from a 7Fr platform.
Use in cases where a specialized right coronary curve geometry is preferred by the operator.
