| titleOfInvention | A venous valve prosthesis |
| abstract | The utility model provides a venous valve prosthesis, which comprises a stent body and a valve; the stent body has an inner cavity, and the stent body includes a proximal-end positioning part, a support part and a distal-end positioning part; the valve is at least connected to the support part, and connects the The lumen is divided into a first segment and a second segment arranged from the proximal end to the distal end, and the valve has a first position and a second position; the venous valve prosthesis is used for implanting the target lumen, and the target lumen is supplied with the target fluid In flow, the valve is in a first position when the valve is subjected to distal-to-proximal pressure from the target fluid, placing the first segment in communication with the second segment to allow the target fluid to flow from the second segment into the first segment , when the valve is subjected to pressure from the target fluid proximally directed towards the second segment, the valve is in a second position isolating the first segment from the second segment to prevent the target fluid from flowing from the first segment into the second segment Segments. The venous valve prosthesis can be implanted into a venous blood vessel and replace the diseased venous valve, thereby preventing blood backflow. |
