Abstract: The present invention discloses a biodegradable molybdenum-based flow diverter and a preparation method thereof, wherein the preparation method comprises the following steps: step 1. pretreatment of a molybdenum wire: cleaning and drying the molybdenum wire, and then weaving to obtain the molybdenum-based flow diverter; step 2. performing heat treatment on the molybdenum-based flow diverter in the step 1; and step 3. performing surface chemical polishing treatment on the molybdenum-based flow diverter subjected to the heat treatment in the step 2. The present invention solves the technical problem that the flow diverter in the prior art cannot be degraded in vivo and therefore easily causing various complications. It provides also improved mechanical property, MRI magnetic resonance imaging (MRI) compatibility as well as biocompatibility, and particularly has the function of promoting rapid endothelialization, compared with other degradable materials.
