The Medtronic Launcher 6Fr RBU45 Coronary Guiding Catheter (REF LA6RBU45) is a single-use coronary guiding catheter engineered to deliver predictable performance, backup support, and lumen integrity during percutaneous coronary interventions. The Launcher family is widely recognized for its three-layer construction designed to balance pushability, torque response, and kink resistance during access to the coronary ostia.

Key Features
Three-layer shaft construction designed for torque transmission and kink resistance.
Stainless steel braid intended to support a large, consistent inner lumen.
Soft, atraumatic distal tip designed to reduce vessel trauma at engagement.
RBU45 (Renal Backup) curve geometry intended to provide passive backup support.
6Fr outer diameter compatible with radial and femoral access workflows.
PTFE inner lining intended to facilitate smooth device delivery and reduce friction.
Sterile, single-use configuration for procedural readiness.

Clinical Applications
Selective cannulation and angiographic visualization of coronary anatomy.
Delivery platform for guidewires, balloons, stents, and adjunct interventional devices.
Procedures requiring backup support during percutaneous coronary intervention (PCI).
Use in cases where a renal-style backup curve is preferred by the operator.
Suitability for any specific clinical scenario should be determined by the treating physician according to the manufacturer's Instructions for Use.
