Abstract

The invention relates to the technical field of medical instruments, and provides a medical balloon, a balloon catheter and a medical device. The medical balloon comprises a balloon body and a plurality of expansion rings arranged outside the balloon body in a sleeving manner, the plurality of expansion rings are sequentially arranged in the length direction of the balloon body, and a pressure charging and releasing cavity is arranged in the balloon body. According to the medical balloon provided by the invention, by sequentially arranging the plurality of expansion rings outside the balloon body in a sleeving manner, when the medical balloon enters a lesion area at a bent blood vessel, the plurality of expansion rings on the inner side of the bent blood vessel are sequentially attached together under the influence of the bent blood vessel to form a flat plane, so that v-shaped creases generated when the balloon body is used alone are completely eliminated, and a lesion area can be smoothly opened. Meanwhile, the superposition of properties of two materials of the balloon body and the expansion rings makes the performance of the medical balloon not restrained by the material performance of an original balloon body any more, and the medical balloon has higher rated pressure and lower compliance.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a medical balloon, a balloon catheter and a medical device. Background technique [0002] Balloon catheters are widely used in the expansion of stenotic lesions in blood vessels, or in the process of stent placement and expansion. When the balloon catheter is used, the guide wire is first inserted into the tip of the balloon and passed through the guide catheter from the proximal end to the opening of the blood vessel, then the guide wire passes through the stenosis, and the balloon follows the guide wire into the lesion. After entering the lesion, inject a mixed solution of contrast agent and saline (1:1) into the balloon to fill the balloon and achieve the effect of dilating the lesion. [0003] The disadvantage of this method is that if the lesion occurs in a curved blood vessel, and the lesion is severely stenotic and complex, during the operation, if...
