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 branched stent graft, a convey system comprising thereof and manufacturing method thereof, the branched stent graft includes a main body () and a side branch (), at least a portion of a lowermost stent section of the side branch () closest to the main body () is not stitched to the cover of the side branch from a lower end to an upper end, the at least a portion of the lowermost stent section is located on a side of the side branch corresponding to a folding direction of the side branch. After deployed, the branched stent graft has an effective supporting force at the base portion of the side branch. In addition, during the deployment of the stent, the side branch can expand to a maximal extent even when the positioning is slightly inaccurate. Further, vascular stenosis or occlusion will not be caused even when subsequent endothelialization occurs.
