Abstract

The invention provides a pulmonary artery drug eluting stent and a stent kit. The pulmonary artery drug eluting stent comprises a plurality of stent split bodies which are spliced to form an annular stent body. Adjacent support split bodies in the circumferential direction of the annular support body are connected through absorbable suture lines. The annular stent body has a to-be-implanted state of a contraction structure and a supporting state of an expansion structure, and the outer diameter of the annular stent body in the supporting state is larger than that of the annular stent body in the to-be-implanted state. According to the invention, the problem that follow-up reconstruction expansion of a lumen is hindered after an existing metal stent is implanted into a human body can be solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pulmonary artery drug-eluting stent and a stent set. Background technique [0002] At present, the treatment methods for pulmonary artery stenosis include thoracotomy, percutaneous balloon angioplasty, and percutaneous stent implantation. Over the years, stent implantation for the treatment of pulmonary artery stenosis has developed rapidly and has become the treatment of choice in many cases. With the emergence of degradable stents in recent years, combined with the introduction of the concept of medical and surgical mosaic therapy, percutaneous pulmonary artery stent implantation has shown its strong clinical application potential. Pulmonary artery stenosis can be congenital, can coexist with almost all types of congenital heart disease, and can also be secondary to surgical scar formation, vascular distortion and compression, etc. At present, there are many reports of post...
