The Medtronic Launcher 8Fr RBU40 Coronary Guiding Catheter (REF LA8RBU40) is a single-use guiding catheter designed to facilitate the placement of interventional devices into the coronary arteries. The Launcher family is engineered with a stainless steel braided shaft and a soft atraumatic tip to deliver a balance of pushability, torque response and lumen integrity throughout complex coronary cases.

Key Features
Backup support shape (RBU 4.0) intended for engagement of the right coronary ostium with enhanced passive support.
8 French outer diameter providing a large inner lumen to accommodate multiple or bulky interventional devices.
Stainless steel braid construction for consistent torque transmission and kink resistance.
Soft, atraumatic distal tip designed to reduce vessel trauma during engagement.
Hydrophilic or PTFE-lined inner lumen for smooth device tracking (per manufacturer specification).
Radiopaque marker and clear hub for fluoroscopic visualization and identification.

Clinical Applications
Percutaneous coronary interventions (PCI) requiring strong backup support.
Delivery of stents, balloons, atherectomy devices, guidewires and other interventional tools.
Cases involving the right coronary artery where additional passive support is preferred.
Procedures where a larger 8Fr lumen is required for complex or multi-device strategies.
