The Medtronic Launcher 7Fr AR20D Coronary Guiding Catheter (REF LA7AR20D) is a single-use guiding catheter designed to facilitate the introduction and guidance of interventional devices into the coronary vasculature. The Launcher family is engineered to deliver consistent torque response, a stable backup support profile, and a smooth lumen finish to support efficient device delivery during percutaneous coronary procedures.

Key Features
Three-layer construction combining an inner PTFE liner, stainless steel braid, and outer polymer jacket for torque transmission and kink resistance.
Pre-shaped AR20D (Amplatz Right 2.0) distal curve intended for engagement of the right coronary artery and selected graft anatomies.
7Fr outer diameter with a large inner lumen designed to accommodate contemporary interventional devices.
Soft, atraumatic distal tip intended to reduce the risk of vessel trauma during ostial engagement.
Hydrophilic-compatible smooth inner lumen for low-friction device tracking.
Standard usable working length consistent with the Launcher product family.

Clinical Applications
Introduction and guidance of interventional cardiology devices into the coronary anatomy.
Selective engagement of the right coronary artery and bypass grafts where an Amplatz Right curve is appropriate.
Support during percutaneous coronary intervention (PCI), including balloon angioplasty and stent delivery, when used in accordance with the manufacturer's Instructions for Use.
