The Medtronic Launcher 8Fr JR40K Coronary Guiding Catheter (REF LA8JR40K) is a single-use coronary guiding catheter designed to provide consistent ostial engagement, stable backup support, and smooth device tracking during percutaneous coronary interventions. The Launcher family is built around a three-layer construction intended to combine torque response, kink resistance, and a large, lubricious lumen for contemporary interventional workflows.

Key Features
Three-layer shaft construction engineered to balance pushability, torque transmission and kink resistance.
Stainless steel braid reinforcement to support precise tip control and shape retention.
Large inner lumen with a lubricious PTFE liner to facilitate contrast delivery and multi-device interventions.
Atraumatic soft tip designed to reduce the risk of vessel trauma during ostial engagement.
Preformed Judkins Right 4.0 (JR4.0) curve optimized for engagement of the right coronary artery.
8Fr outer diameter offering enhanced backup support for complex interventions and bulkier device delivery.

Clinical Applications
Diagnostic and interventional cannulation of the right coronary artery via the JR4.0 curve.
Delivery of interventional devices including balloon catheters, stents and guidewires.
Complex coronary interventions where additional backup support and a larger working lumen are preferred.
Procedures performed via femoral access where 8Fr guiding catheters are clinically indicated.
