What type of catheter was used as a guiding catheter during the procedure?

The 6 French JL3.5 catheter is designed specifically for guiding purposes, often in vascular or cardiac procedures. Its shape is tailored to navigate the anatomy effectively, especially in accessing the coronary arteries or other vasculature. The French size indicates the outer diameter, with a 6 French catheter being a suitable choice for offering a balance between stability and maneuverability.

Guiding catheters need to be both firm enough to provide adequate support for devices introduced through them and flexible enough to navigate through complex vascular pathways. The 6 French JL3.5 catheter meets these criteria well, making it a common selection in procedures that require precise guidance and access.

In contrast, the other options serve different purposes or may not provide the same level of effective navigation or stability necessary for guiding during such procedures. For instance, the multipurpose catheter, while versatile, may not offer the same specific design advantages as the JL3.5 for optimal guiding.
