Abstract

The invention relates to the technical field of stent conveying of integral exchange type balloon dilatation catheters, and discloses an integral exchange type balloon stent mounting device and a stent mounting method. The integral exchange type balloon stent mounting device is used for mounting a self-expanding stent on a diseased region of a blood vessel, and comprises a balloon dilatation catheter and a stent release tube. A first through hole is formed in the balloon dilatation catheter in the length direction, an inlet is formed in the near end of the first through hole, and an outlet is formed in the far end of the first through hole; an expansion part is arranged at the far end of the balloon dilatation catheter, and the self-expanding stent is slidably mounted in the first through hole and located at the far end of the balloon dilatation catheter; the stent release tube is arranged in the first through hole in a penetrating mode through the inlet, the stent release tube is slidably arranged in the first through hole of the balloon dilatation catheter, and the far end of the stent release tube abuts against the self-expanding stent; and a second through hole is formed in the stent release tube in the length direction, and a micro guide wire sequentially penetrates through the outlet of the first through hole, the self-expanding stent and the second through hole.

Description

technical field [0001] The invention relates to the technical field of stent delivery of an integrally exchangeable balloon dilatation catheter, in particular to an integrally exchangeable balloon stent installation device and a stent installation method. Background technique [0002] Vascular stenosis is a common vascular disease and an important cause and risk factor of ischemic vascular disease. At present, vascular stent implantation is one of the important technologies for the treatment of vascular stenosis. The stent implantation of the self-expandable stent is usually pre-expanded with a balloon catheter, and then the stent is delivered to the lesion site to be released and automatically expanded to expand the blood vessel. [0003] In the current operation process, the doctor needs to deliver the microcatheter and the microguide wire to the lesion, then remove the microcatheter, insert the balloon catheter to pre-dilate the lesion, and then withdraw the balloon cath...
