Radioactive esophageal stents

Used in conjunction with radioactive seeds for patients with middle and late esophageal cancer to keep the esophagus unobstructed and treat tumors.

The stent expands the narrow cavity to relieve the condition and carries the radiation source to irradiate the tumor and inhibit its growth. Made of Ti-Ni alloy tube with memory characteristics and super elasticity, providing excellent biocompatibility and corrosion resistance. The radiation source can be fixed at any position inside the stent tube for conformal treatment of tumors.
