1, coronary angiography catheters are used to perform coronary angiography, a procedure used to assess blood flow in the coronary arteries. The catheter is inserted into the patient's arteries, and then the coronary arteries are visualized with a radioactive contrast agent to help the doctor diagnose coronary artery disease or narrowing of the coronary arteries.
2. Guidewires are thin metal wires that are used to guide other catheters and devices into the coronary arteries and are useful when traveling through narrow or tortuous vessels to ensure that the catheter reaches the target area accurately.
