Abstract

The invention discloses a preparation method of a drug balloon. The preparation method comprises the following steps of step 1, designing a three-dimensional model of a balloon body and a drug coating of the drug balloon by using modeling software, and importing a printing file of the three-dimensional model into a printer; step 2, adding a printing material of the drug coating into the printer, and printing a first drug coating according to the printing file; and step 3, connecting and fixing the balloon body with the first drug coating. According to the drug balloon prepared by the preparation method disclosed by the invention, the drug coating can be uniformly and firmly fixed on the surface of the balloon body, so that elution of drugs in an in-vivo delivery process is reduced, and the utilization rate of the drugs is increased; and the preparation method is accurate, stable and efficient, is suitable for industrial large-scale production and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of drug balloons, in particular to a preparation method of drug balloons, the prepared drug balloons and applications thereof. Background technique [0002] Vascular stenosis is a common clinical disease. Vascular stenosis can easily lead to poor blood flow in blood vessels, and in severe cases, it can even block blood vessels and cause life-threatening. At present, the main treatment methods for vascular stenosis include the placement of vascular stents and drug delivery by drug balloons. [0003] The invention of the stent provides a better solution for atherosclerosis and intravascular stenosis, which greatly improves the treatment efficiency, but at the same time intravascular and intrastent restenosis occurs, for small vessels, bifurcated vessels and in situ Disadvantages such as unsatisfactory therapeutic effect of pathological changes etc. [0004] Drug balloons can be used to address restenosis. ...
