The present disclosure provides a pulmonary artery stent. The pulmonary artery stent includes: a metal stent capable of circumferential expansion; and an isolation membrane wrapping the metal stent to isolate the metal stent from an external environment, and the isolation membrane having a circumferential tensile strength less than an axial tensile strength. The embodiments of the present disclosure can not only expand the diameter of the stent according to a change in the diameter of a blood vessel to meet a support performance requirement after the blood vessel enlarges but also isolate the metal portion of the stent from a vascular environment, thus effectively solving a problem of in-stent restenosis.
