The present invention relates to a developing wire and an occluder with developing function. The developing wire of the present invention comprises a wire main body and a first control end and a second control end arranged on the wire main body for picking and placing the wire main body, the first control end and the second control end are respectively located at two ends of the wire main body The material of the developing wire is a polymer wire with a lubricating layer on the surface, and the lubricating layer supports the developing material; or the developing wire is a hydrogel wire carrying the developing material. The developing wire of the present invention can be operated and withdrawn in vitro after the occluder is released, which can prevent the developing mark from permanently remaining in the body, and can expand the developing range at the same time, which is beneficial to reduce the difficulty and risk of surgery, and has lower elastic modulus and friction. resistance, the tip of the developing filament will not cause damage to the tissue when withdrawn. |
