The present invention relates to a projection-type partially dual-structured stent. Provided is a technique according to which a projecting portion coupled to a main body portion allows a stent to be well fixed and maintained inside a canal in the human body. According to the present invention, a first projection and a second projection of the projecting portion cross each other and project in an inclined manner in different directions, and thus the projection-type partially dual-structured stent is rigidly fixed in a canal in the human body without shaking in the left and right directions when subjected to external forces. Also, the number of projecting portions can be adjusted depending on the situation so as to simplify the manufacturing process and reduce manufacturing costs. Further, a cover portion coupled to the main body portion prevents a lesion portion from penetrating into the projection-type partially dual-structured stent, thus preventing restenosis caused by the lesion portion. |
