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.

Abstract: An electrode plate includes a current collector which includes an insulating layer, a first conductor layer and a second conductor layer disposed on two sides of the insulating layer respectively, and a conductive connector. The outward side of the first conductor layer is provided with a first blank region and a first active material coating layer. The outward side of the second conductor layer is provided with a second blank region and a second active material coating layer. The first blank region is provided with a folded region, and the second blank region covers the first blank region. One end of the conductive connector extends out of the folded region to connect the first blank region. The other end of the conductive connector is connected to the second blank region. The conductive connector is adapted to electrically connect the first blank region and the second blank region.
