Angiographic catheters and Guiding catheters play an important role in percutaneous coronary intervention. The structure and performance of the Angiographic catheter determine whether the contrast agent can be successfully injected into the target vessel, thus providing a preliminary basis for the diagnosis of the disease. Guiding catheter provides access for related devices and determines whether percutaneous coronary intervention can be carried out smoothly. The structure of the angiographic catheter and the guiding catheter are described in detail. The angiographic catheter consists of hub, relief, body, bridge section and soft tip. The structure of the guiding catheter includes hub, relief, pushing section, kink-resistance section, coaxial section and a soft tip. The materials and processing technology involved in each component of angiographic catheter and guiding catheter are described and analyzed in detail.
