Introducing Angiographic Catheter And Guide Catheter

In order to better enter the blood vessel, the head end of the angiography catheter is designed into different shapes and sizes for different coronary artery branches or peripheral arteries.

Although patients with some vascular related diseases may be diagnosed by other methods, such as CT, MRI, EKG, ultrasound, etc., before or during specific interventional medical treatment, such as percutaneous transluminal coronary angioplasty (PTCA), in order to clarify the specific location and degree of the disease, it is often necessary to inject contrast agent before and during the operation, guide accurate treatment through DSA development.

As shown in the figure, the site of coronary stenosis is achieved by injecting contrast agent through angiographic catheter and under the DSA equipment. It not only further clarified the diagnosis, but also provided information such as the location, length and diameter of the lesion, which provided the basis for further treatment - dilating the stenosis lesion with PTCA balloon and implanting the stent.

The features of angiographic catheter

The angiographic catheter has appropriate hardness, elasticity, flexibility and torsion control force. The catheter itself has good X-ray impermeability and high development performance; The angiographic catheter is generally composed of three layers: the outer layer: special polyethylene plastic material, which is related to the shape and hardness of the catheter and the friction with the intima of blood vessels; Middle layer: steel wire braided structure to ensure that the conduit will not collapse and break, and ensure that the conduit can withstand a certain pressure; Inner layer: Nylon PTFE coating. Play a certain role in lubrication, reduce the friction when the contrast medium passes through and maintain the flow.

How to choose suitable angiography catheter

In order to better enter the blood vessel, the head end of the angiography catheter is designed into different shapes and sizes for different coronary artery branches or peripheral arteries. When selecting the angiography catheter, the doctor needs to select the appropriate shape and size of the head end according to the lesion location, the vascular direction of the organ or anatomical characteristics.

The features of guide catheter

The structure of the guide catheter is similar to that of the contrast tube, but the manufacturing process of the guide catheter is higher. When the outer diameter is the same, the inner cavity of guide catheter is required to be larger in order to accommodate the guide wire, balloon, stent and other equipment. After treatment, contrast agent can also be injected through the guide catheter to observe the treatment effect.
