The Medtronic Launcher 7Fr RBU35 Coronary Guiding Catheter (REF LA7RBU35) is a single-lumen guiding catheter designed to provide stable cannulation, predictable backup support, and an optimized inner lumen for the introduction of diagnostic and interventional devices into the coronary vasculature. The Launcher family combines a stainless steel braided shaft with a soft, atraumatic tip to balance torque response, kink resistance, and vessel safety during cardiac catheterization procedures.

Key Features
- RBU35 curve intended to deliver enhanced backup support, typically used as a right coronary alternative geometry.
- 7 French outer diameter shaft suited to a broad range of interventional device profiles.
- Stainless steel braided construction for 1:1 torque transmission and kink resistance.
- Soft atraumatic tip designed to reduce the risk of ostial trauma during engagement.
- Large, smooth inner lumen with PTFE lining to facilitate device tracking and contrast delivery.
- Hydrophilic-free outer surface profile consistent with the Launcher platform (verify in current IFU).

Clinical Applications
- Selective cannulation of coronary ostia for diagnostic angiography.
- Support catheter for percutaneous coronary intervention (PCI), including balloon and stent delivery.
- Conduit for adjunctive interventional devices such as guidewires, microcatheters, and thrombectomy or atherectomy systems where compatible.
- Cases requiring additional backup support beyond standard Judkins-style curves.
