The 4D‐printing technology is applied to fabricate a shape memory peripheral stent with good biocompatibility, which sustains long‐term drug release. The star polymer s‐PCL is prepared by ring opening polymerization of ε‐caprolactone with the ‐OH of β‐cyclodextrin (βCD) as initiator, and then the s‐...
