| titleOfInvention | A coated TIPS covered stent |
| abstract | The patent of the present invention relates to a medical device, specifically a coated transjugular intrahepatic portal vein puncture stent (TIPS stent), which is composed of an inner surface coating, a bare stent, an outer surface coating, and an intermediate shunt device. , The intermediate shunt device of the product is composed of multiple valve systems. The valve of the valve system can automatically adjust the opening amplitude of the valve according to the pressure of the portal vein, thereby adjusting the pressure of the portal vein. The multiple valve systems in the product mid-shunt device also reduce the area of stagnant blood on the dorsal side of the valve, reducing the formation of thrombus on the dorsal side of the valve. The bare stent of the product is coated with parylene coating, which can prevent the stent from being corroded by blood, and prevent the metal ions of the stent from entering the human body and endangering the health of the patient. The product heparin coating prevents tissue proliferation at the stent implantation site and prevents stenosis inside the stent. |
