The Medtronic Launcher 8Fr JCR40 Coronary Guiding Catheter (REF LA8JCR40) is a single-use coronary guiding catheter designed to facilitate access to the right coronary artery during percutaneous coronary interventions. Its Judkins Right 4.0 (JCR40) curve is intended to provide predictable seating and stable backup support, while the 8Fr profile accommodates a broad range of interventional devices.

Key Features
- Curve: Judkins Right 4.0 (JCR40), shaped for right coronary artery cannulation.
- Outer diameter: 8 French.
- Three-layer construction designed to combine kink resistance, torque transmission and lumen integrity.
- Stainless steel braid intended to support 1:1 torque response and pushability.
- PTFE inner lining to promote smooth device delivery and reduce friction.
- Soft, atraumatic distal tip intended to minimize vessel trauma during engagement.
- Large inner lumen consistent with the Launcher 8Fr platform to support complex interventional device passage.
- Working length: Not specified in the located sources.

Clinical Applications
- Guiding catheter access for percutaneous coronary intervention (PCI) of the right coronary artery.
- Delivery and exchange of interventional devices including balloon catheters, stents and adjunctive PCI tools.
- Procedures requiring an 8Fr platform for enhanced backup support or simultaneous device use (e.g., kissing balloon or two-stent bifurcation strategies), per operator discretion.
