## Abstract

Provided are a vascular stent, a conveying balloon thereof, and an implanting system. The vascular stent comprises a flexible light-transmitting body. The flexible light-transmitting body is provided with a hardenable channel. The hardenable channel is arranged in the circumferential direction and the axial direction of the flexible light-transmitting body. The hardenable channel is used for filling a liquid photocuring supporting material, and the liquid photocuring supporting material is cured after being illuminated so as to radially support the flexible light-transmitting body.

## Claims

### Claim 1

An implanting system for implanting a vascular stent, comprising a vascular stent, a stent conveying device for releasably receiving the vascular stent, a light source for illuminating the vascular stent, and a liquid supply pipe for conveying a liquid photocuring supporting material, wherein the vascular stent comprises a flexible light-transmitting body, the flexible light-transmitting body being provided with a hardenable channel, the hardenable channel being arranged in a circumferential direction and an axial direction of the flexible light-transmitting body, wherein the hardenable channel is filled with a liquid photocuring supporting material, and the liquid photocuring supporting material is cured after being illuminated so as to radially support the flexible light-transmitting body; and the liquid supply pipe is detachably connected to the vascular stent,
wherein the stent conveying device is a conveying balloon, the conveying balloon comprises a balloon body and a control pipeline for filling the balloon body with air or liquid, the light source is disposed in the balloon body, and a side wall of the balloon body is made of a light-transmitting material,
the implanting system further comprising a pipe cutting assembly, the pipe cutting assembly comprising a top core and a cutting wire, a distal end surface of the top core being formed with a cutting groove, two ends of the cutting wire movably penetrating through the top core along the axial direction from the cutting groove and stretching out from a proximal end, and the liquid supply pipe passing between the cutting wire and the cutting groove.

### Claim 2 (depends on 1)

The implanting system according to claim 1 wherein the liquid photocuring supporting material is UV resin.

### Claim 3 (depends on 1)

The implanting system according to claim 1 wherein the hardenable channel is a spiral tubular structure extending along a side wall of the flexible light-transmitting body.

### Claim 4 (depends on 1)

The implanting system according to claim 1, wherein the hardenable channel is a mesh structure arranged along a side wall of the flexible light-transmitting body.

### Claim 5 (depends on 1)

The implanting system according to claim 1, wherein the vascular stent is an aortic vascular stent.

### Claim 6 (depends on 1)

The implanting system according to claim 1, wherein the flexible light-transmitting body is made of a polyvinylidene fluoride material.
