Catheters

1. Catheters

2. Function:  Long, hollow tubes inserted into a vessel for diagnostics, therapeutic device delivery, and drug administration. Diagnostic Catheters: Purpose:  Used for angiography to visualize vessels. Design:  Available in various pre-formed shapes for selective cannulation of specific arteries. Guiding Catheters: Purpose:  Provide a stable and supportive pathway for smaller catheters and other devices. Design:  Larger and stiffer than diagnostic catheters, with a braided core for support. Microcatheters: Purpose:  Used to navigate and access extremely small or delicate vessels. Size:  Smaller diameter (e.g., 2-3F) and accommodate smaller guidewires (0.010-0.018 inch). Use Cases:  Essential for procedures like chemoembolization and neurovascular interventions.
