The Medtronic Launcher 8Fr SR40 Coronary Guiding Catheter (REF LA8SR40) is a single-use guiding catheter designed to provide stable coaxial access and reliable backup support during percutaneous coronary interventions. The Launcher family is engineered with a three-layer construction intended to deliver responsive torque, smooth device tracking, and a large unobstructed inner lumen for contrast injection and device delivery.

Key Features
- Three-layer construction combining an inner lubricious liner, stainless steel braid, and an outer polymer jacket for torque transmission and kink resistance.
- SR40 curve shape configured for engagement of the right coronary ostium.
- 8 French outer diameter providing a large inner lumen to accommodate multiple or larger interventional devices.
- Soft atraumatic tip designed to reduce vessel trauma during cannulation.
- Full-length radiopaque shaft visualization characteristics consistent with the Launcher platform.
- Sterile, single-use packaging.

Clinical Applications
- Coronary angiography and diagnostic catheterization where additional support is required.
- Percutaneous coronary intervention (PCI) procedures requiring stable guide engagement.
- Delivery of guidewires, balloons, stents, and other interventional devices through the coronary vasculature.
- Cases requiring a larger 8Fr lumen, including selected complex or multi-device interventions.
