Abstract

The invention relates to the technical field of medical instruments, and particularly relates to an intracranial medicine balloon. A first air hole corresponds to an expansion balloon; a second air hole is formed in the end, close to a balloon body, of a catheter; a first expansion membrane is arranged in the second air hole; and a first protruding block is arranged at the end, close to a split, of the first expansion membrane. When the balloon body reaches a lesion, a pressure medium is injected into the catheter, part of the pressure medium enters the expansion balloon through the first air hole, the expansion balloon expands to make full contact with the blood vessel wall of the lesion under the pressure effect, part of the pressure medium applies pressure to the first expansion membrane through the second air hole, the first expansion membrane is stressed to deform, the medicine balloon is punctured through the first protruding block, medicine in the medicine balloon overflows to the lesion for treatment, and the situation that the medicine is diluted before reaching the lesion, and consequently the treatment effect is reduced is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intracranial drug balloon. Background technique [0002] In recent years, drug balloons to prevent vascular restenosis after interventional therapy have appeared. Anti-vascular intimal hyperplasia drugs are coated on the surface of the balloon. The technology of intima-mural contact and drug release into the local vessel wall. [0003] However, in the existing intracranial drug balloons, the drug is coated on the surface of the balloon, and when transported in the blood vessel, part of the drug will be washed away by the blood, resulting in reduced curative effect. Contents of the invention [0004] The object of the present invention is to provide an intracranial drug balloon, which solves the problem that the existing intracranial drug balloons in the prior art are all coated with drugs on the surface of the balloon, and when transported in the blood vessel, it wi...
