The Medtronic Launcher 8Fr MAC50 Coronary Guiding Catheter (REF LA8MAC50) is a single-lumen guiding catheter designed to facilitate access to the coronary ostia and provide a stable platform for the introduction and exchange of interventional devices. The Launcher family combines a stainless steel braided shaft with a smooth inner lumen and a soft, atraumatic tip to support reliable backup, smooth device tracking, and high-flow contrast injection in routine and complex percutaneous coronary interventions.

Key Features
- MAC50 (Multipurpose A Curve, 5.0) tip configuration intended for selective engagement where a multipurpose-style curve is preferred.
- 8 French outer diameter offering a large inner lumen to accommodate multiple or bulky interventional devices.
- Stainless steel braided shaft for 1:1 torque transmission and kink resistance.
- Soft atraumatic tip designed to reduce the risk of ostial trauma during engagement.
- Lubricious inner lumen to support smooth device delivery, exchange, and contrast flow.
- Radiopaque tip marker for fluoroscopic visualization.
- Working length: Not specified in the located sources.

Clinical Applications
- Selective cannulation of native coronary arteries and bypass grafts where a multipurpose-style curve is appropriate.
- Platform for delivery of guidewires, balloon catheters, stents, and adjunctive devices during percutaneous coronary intervention.
- Procedures requiring strong passive support and a large 8Fr lumen for complex or multi-device interventions.
