The present invention provides a filter device, including a filtering part, a constraining part, a stent part, and a connecting part. The filtering part has a first end and a second end opposite to each other. The constraining part is degradable and at least configured to constrain the first end of the filtering part. The stent part has a first end and a second end opposite to each other. The first end of the stent part is connected to the second end of the filtering part, and disposed coaxial with the filtering part. The connecting part is disposed on one or more of the first end of the filtering part and the second end of the stent part, and is configured to connect to an external mechanism, and the constraining part is further configured to constrain the second end of the stent part when the connecting part is disposed at the second end of the stent part. The present invention can be taken out from the human body and can also be partially degraded in the human body so that the occurrence rate of long-term complications is reduced, and secondary surgery can thus be avoided.

Filter device

A stent () used for a heart valve prosthesis and the heart valve prosthesis that includes the stent () and is used for heart valve replacement. The stent is configured to support a heart valve () and includes, along a longitudinal axis, an inflow section (), an outflow section () and a transition section () between the inflow section () and the outflow section (). The stent () has a contracted delivery configuration and an expanded deployed configuration. In the expanded deployed configuration, the inflow section () defines a concave contour that is complementary to a structure of a native valve annulus. The concave contour enables self-deployment and close adherence of the stent (), thereby preventing its displacement and perivalvular leakage after implantation.
