Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of double-layer drug balloon, aiming to solve the problem that the expansion balloon in the prior art expands the blood vessel for a certain period of time, the blood vessel will shrink due to inertia, and the drug balloon does not have a good expansion function. Therefore, it is impossible to continue to apply medicine, which affects the technical problems of the treatment effect.

Abstract

The invention relates to the technical field of medical instruments, in particular to a novel double-layer medicine balloon. Specific substances are conveyed to the dilation balloon through the communication assembly, so that the dilation balloon is expanded, the dilation balloon is arranged in the medicine balloon, then the medicine balloon is driven to be expanded, the blood vessel is dilated, the microneedle is arranged on the outer wall of the medicine balloon and punctures into the blood vessel by a common depth along with expansion of the medicine balloon, and then medicine is conveyed to the medicine balloon through the communication assembly. Furthermore, the medicine is injected into the blood vessel through the microneedle, the medicine applying effect is better, meanwhile, the dilation balloon is arranged in the medicine balloon, medicine applying while dilation and continuous medicine applying are achieved, the medicine applying time is controllable, and the treatment effect is promoted to be better.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel double-layer drug balloon. Background technique [0002] At present, balloons are basically used instead of stents in coronary surgery, usually two balloons, one is a dilation balloon and the other is a drug balloon. Dosing with a drug balloon. [0003] However, after the dilation balloon dilates the blood vessel for a certain period of time, the blood vessel will contract due to inertia, and the current indications for the dilation of the drug balloon are: coronary artery disease with a small diameter (2mm), in-stent restenosis disease, etc. There are several points Defects: 1. The outer layer of the drug balloon is a solid drug coating, which has small bending ability and poor ability to pass through coronary vessels with a large bending angle; 2. After the drug balloon reaches the target site, it expands to a certain diameter for 60 seconds. The amount of the...
