Self-adaptive cross-arch thoracic aorta covered stent and system thereof

The invention discloses a self-adaptive arch-crossing thoracic aorta covered stent which comprises a covered stent body and an embedded branch part, and the embedded branch part is embedded in the covered stent body so that the embedded branch part and the covered stent body can be of an integrated structure; the covered stent main body comprises a metal stent part and a covering film, and the metal stent part supports the covering film to form the covered stent with embedded branches; the embedded branch part comprises a plurality of embedded branch stents and a co-stem body, at least two embedded branch stents and the co-stem body are arranged in a co-stem mode and communicated, and each branch stent is independently used for operation of a branch vascular stent in a subsequent operation; and the embedded branch parts are respectively and independently communicated with the inside and outside of the bracket. According to the self-adaptive cross-arch thoracic aorta covered stent and the system thereof, the s
