The Medtronic Launcher 6Fr FL40ST Coronary Guiding Catheter (REF LA6FL40ST) is a single-use coronary guiding catheter designed to facilitate access to the coronary ostia and provide a stable conduit for the delivery of diagnostic and interventional devices. The Launcher family is built on a three-layer construction intended to combine torque response, kink resistance, and a large, smooth inner lumen for device passage.

Key Features
- 6 French outer diameter for radial or femoral access, depending on operator preference and patient anatomy.
- FL (Left side-hole/Left coronary) 4.0 curve shape configured for engagement of the left coronary system.
- ST configuration as indicated by the reference code.
- Three-layer shaft construction with stainless steel braid for torque transmission and kink resistance.
- PTFE-lined inner lumen intended to support smooth device delivery and contrast injection.
- Soft, atraumatic distal tip designed to reduce the risk of vessel trauma during engagement.
- Radiopaque shaft to support fluoroscopic visualization.

Clinical Applications
- Selective angiography of the coronary arteries.
- Conduit for delivery of percutaneous coronary intervention (PCI) devices, including guidewires, balloon catheters, and stent delivery systems.
- Support during complex coronary interventions where predictable backup and torque response are required.
- Compatible with standard cath lab workflows for diagnostic and interventional cardiology.
