This invention discloses a highly flexible appendiceal
stent, comprising a proximal anchoring section, a middle flexible section, and a
stent body. The outer wall of the
stent body is provided with one or more anti-displacement rings. The stent is composed of multiple
layers; preferably, the outer layer material of a three-layer stent is one or more combinations of
polyurethane, modified nylon Pebax, and nylon. The outer layer materials of the stent body and the flexible section are more flexible than the proximal outer layer material. The middle imaging-enhancing layer is a spring mesh or braided mesh made of
metal wires; the inner layer is a super-slippery
polytetrafluoroethylene film. Compared to currently used appendiceal stents released via
digestive endoscopy, the stent body of this invention is more flexible, causing less damage to the appendix. The stent with the flexible section is less prone to bending and provides smooth drainage. Furthermore, the appendiceal stent of this invention shows good imaging under X-rays, facilitating
surgery. The anti-displacement rings and barbs placed in the stent body reduce the risk of displacement.
