Abstract
A covered stent (A), including a mesh-shaped support structure, and further including a first section (A) and a second section (A) connected to a proximal end and/or a distal end of the first section. The first section includes a plurality of first corrugated rings (A), and a first covering film (A) which covers surfaces of the first corrugated rings; the second section includes a plurality of second corrugated rings (A), two adjacent second corrugated rings being fixedly connected to each other; a plurality of windows (A) are formed between the plurality of second corrugated rings; and the plurality of first corrugated rings and the plurality of second corrugated rings form the support structure. The second section of the covered stent will not block an opening of a branch vessel (), and thus it is not necessary to reduce the length of the covered stent in a main branch vessel, such that the covered stent has a sufficiently long anchoring area in the main branch vessel so as to ensure that the covered stent has sufficient anchoring force and thus prevent the displacement or endoleak of a distal end of the covered stent, thereby ensuring a good occluding effect.
