The Medtronic Launcher 7Fr AR20 Coronary Guiding Catheter (REF LA7AR20) is a single-use coronary guiding catheter designed to provide consistent backup support, smooth tracking, and accurate torque transmission during diagnostic and interventional coronary procedures. The Launcher family is built on a three-layer construction intended to deliver a stable platform for device delivery while maintaining lumen integrity.

Key Features
Three-layer shaft construction designed for kink resistance and torque response.
Large, smooth inner lumen intended to facilitate device delivery and contrast injection.
Preformed AR20 (Amplatz Right 2.0) curve for engagement of the right coronary artery and select graft anatomies.
7Fr outer diameter sizing for procedures requiring larger-profile device support.
Soft, tapered atraumatic tip designed to reduce vessel trauma during cannulation.
Hydrophilic-free polymer outer jacket for predictable handling.

Clinical Applications
Used by trained interventional cardiologists as a conduit for the introduction of interventional and diagnostic devices into the coronary vasculature.
Supports delivery of balloons, stents, and adjunctive devices during percutaneous coronary intervention.
AR20 curve typically selected for right coronary artery and certain bypass graft engagements.
