The Medtronic Launcher 5Fr JCL4.0 Coronary Guiding Catheter (REF LA5JCL40) is a single-use guiding catheter engineered to deliver predictable support, torque response and lumen integrity during percutaneous coronary procedures. The Judkins Left 4.0 (JCL4.0) curve is intended for selective engagement of the left coronary ostium via a femoral approach, supporting both diagnostic angiography and interventional device delivery in compatible anatomies.

Key Features
- Three-layer shaft construction combining an inner PTFE liner, a stainless steel braid and an outer polymer jacket for torque transmission and kink resistance.
- Judkins Left 4.0 (JCL4.0) preformed curve for selective left main coronary engagement.
- 5 French outer diameter with a large inner lumen designed to accommodate standard coronary interventional devices compatible with 5Fr guides.
- Soft, atraumatic distal tip intended to reduce vessel trauma at the ostium.
- Hydrophilic-friendly inner lumen designed for smooth device tracking and contrast delivery.
- Radiopaque construction for fluoroscopic visualization.
- Sterile, single-use packaging.

Clinical Applications
- Selective cannulation of the left coronary artery via femoral access.
- Diagnostic coronary angiography support.
- Conduit for delivery of guidewires, balloon catheters, stents and other interventional devices compatible with a 5Fr guiding catheter.
- Use in cardiac catheterization laboratory environments by trained interventional cardiologists.
