The Medtronic Launcher 7Fr JR40D Coronary Guiding Catheter (REF LA7JR40D) is a single-use guiding catheter engineered to provide reliable coronary access and predictable performance during percutaneous coronary interventions. The Judkins Right (JR4.0) curve is a workhorse configuration intended to facilitate selective engagement of the right coronary artery from a femoral approach, while the 7Fr outer diameter supports a broad range of interventional devices through a generous inner lumen.

Key Features
Three-layer shaft construction designed to balance pushability, torque response, and kink resistance.
Stainless steel braid reinforcement for accurate 1:1 torque transmission and shape retention.
Soft, atraumatic distal tip intended to reduce the risk of vessel trauma during engagement.
PTFE-lined inner lumen to support smooth delivery of balloons, stents, and adjunctive interventional devices.
Preformed Judkins Right 4.0 (JR40D) curve for selective right coronary artery cannulation.
7Fr outer diameter compatible with larger-profile and complex PCI device combinations.
Sterile, single-use packaging consistent with interventional cardiology workflow requirements.

Clinical Applications
Intended for use as a conduit during diagnostic and interventional cardiovascular procedures.
Selective engagement and contrast delivery to the right coronary artery.
Support platform for percutaneous coronary intervention, including balloon angioplasty and stent deployment.
Delivery of adjunctive interventional devices where a 7Fr guiding catheter is appropriate.
Typically used via a femoral arterial access approach where clinically indicated.
