The present invention provides a tube-net type blood vessel sent carved by a metal round tube, comprising a plurality of ring supporting bodies which are identical in structure and arranged along the axial direction, wherein every two ring supporting bodies are one group, two ring supporting bodies in the group are arranged in a mirror symmetry manner, and connected through a plurality of connectors with a shape like a Chinese character 'Ji', the groups are aligned and connected through a plurality of connectors with a lateral '{' shape. The tube-net type blood vessel sent of the invention not only keeps higher radial support after expanded, but also has good axial flexibility and blood vessel compliance, small axial shortening rate, as well as moderate metallic surface coverage. Each component part of the whole sent is uniform and symmetric, which reduces the possibility that each part of the sent rotates relatively around the sent in the axial direction during the expansion.
