Catheters are flexible medical devices used to access, navigate, and treat the cardiovascular system during diagnostic and interventional procedures. Available in a variety of designs for applications such as angiography, angioplasty, electrophysiology, and structural heart interventions, they enable precise delivery of contrast media, therapeutic devices, and medications. Engineered for optimal flexibility, torque control, and trackability, catheters support safe, efficient procedures and improved clinical outcomes across a wide range of cardiovascular treatments.
