Provided are a balloon stent installation device and a stent installation method. The balloon stent installation device, which is used to install a self-expandable stent to a lesion site of a blood vessel, includes a balloon dilatation catheter and a stent release tube. The balloon dilatation catheter includes a first through hole with an inlet and an outlet. An expansion part is disposed at a distal end of the balloon dilatation catheter. The self-expandable stent is slidably mounted in the first through hole and located at a distal end of the balloon dilatation catheter. The stent release tube is slidably disposed in the first through hole. A distal end of the stent release tube abuts against the self-expandable stent and includes a second through hole. A micro guidewire is configured to be inserted sequentially through the outlet of the first through hole, the self-expandable stent, and the second through hole.

Balloon stent installation device and stent installation method

A covered stent () is provided, including a stent body () and a filter membrane (). The stent body () has a proximal end () and a distal end (). The proximal end () is configured to be arranged upstream in the blood vessel with respect to the distal end (). The filter membrane () has a mounting portion () and a free portion (). The mounting portion () is connected with the stent body (), and the free portion () is connected with the mounting portion () and free from the stent body ().

Covered stent

A distal protector includes a delivery guidewire assembly, an umbrella filter assembly and a coating assembly. The delivery guidewire assembly includes a delivery guidewire. The umbrella filter assembly includes an umbrella skeleton, a filter membrane and a fixed ring. The delivery guidewire detachably passes through the umbrella filter assembly. The fixed ring is disposed at a first end of the umbrella skeleton. The filter membrane covers the umbrella skeleton. A portion of the filter membrane being away from the first end of the umbrella skeleton is provided with filter holes. The coating assembly is disposed at a second end of the umbrella filter assembly being away from the fixed ring and includes a carrier and a thrombolytic drug carried in the carrier. The thrombolytic drug is configured to be released at a preset rate.

Distal protection device and manufacturing method therefor

A step-cutting thrombectomy device and a thrombectomy system is disclosed. The step-cutting thrombectomy device includes the following: multiple first cutting components capable of elastically expanding in a radial direction and configured to cut a thrombus in a longitudinal direction of a blood vessel; multiple second cutting components, capable of elastically expanding in the radial direction and configured to cut the thrombus in a circumferential direction of the blood vessel a collection device, configured to collect a crushed thrombus; and a push tube. The first cutting components, the second cutting components and the collection device are sequentially disposed on the push tube from the proximal end to the distal end.
