| abstract |
A balloon stent comprises a drug balloon (1) having a deflated state and an expanded state, and a stent assembly; the stent assembly comprises at least two stents (2) sleeved on the periphery of the drug balloon (1), and the at least two stents (2) are provided at intervals along the axial direction of the stents. The stent assembly is designed in such a way that at least two stents are provided at intervals, being able to effectively reduce the stent coverage and the implant volume, and reduce the probability of the occurrence of restenosis; furthermore, if restenosis occurs, a stent can be implanted again in the gap between two adjacent stents for treatment. |
