  • Patent number: 12491094
    Abstract: The present disclosure relates to a stent for a TIPS surgery, including a first stent body and a second stent body. During use, the first stent body sleeves the second stent body, to control a self-expansion range of the second stent body. The first stent body includes first connectors, intermediate connectors, and second connectors. The second stent body is formed by weaving a single strand of memory alloy. The second stent body includes a first segment and a second segment which are connected. The first segment is of a woven spiral structure, and the second segment is of a woven self-locking structure. By arranging the first stent body to include the first connectors, the intermediate connectors, and the second connectors, the first stent body can shorten to a minimal extent in a length direction during expansion.
