Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a fiber winding balloon and a preparation method thereof.
Background
Balloon dilation catheters have been widely used in the treatment of vascular stenosis or natural lumen stenosis in humans. However, for the vascular stenosis diseases (such as arterial stenosis of lower limbs or arteriovenous fistula) with high calcification, hyperplasia or fibrosis, a common balloon dilation catheter cannot dilate a lesion part due to lower pressure, even if a high-pressure balloon dilation catheter (rated burst pressure of 20-26 atm) is used for dilation, a dog bone effect is easy to generate due to the fact that the balloon is not strong in compliance, so that the dilating diameter is far greater than the nominal diameter, and serious damage is caused to the blood vessel. In addition, aiming at the common urinary obstruction diseases such as the dilation of a percutaneous nephrolithotomy channel (treating kidney stones), fibrosis ureteral stenosis or urethral stenosis, the common balloon dilation catheter also can fail to dilate due to insufficient pressure, and the balloon dilation catheter is easy to deform in a banana shape under high pressure, which is not beneficial to the establishment of the lithotomy channel. Therefore, development of an ultrahigh pressure balloon (rated burst pressure is more than or equal to 30 atm) with ultrahigh burst pressure and extremely high non-compliance is always a clinical requirement in the field, and is also an important technical difficulty to break through.
Chinese issued patent number CN111818961a (application number CN 201880090980.5) discloses an inflatable medical balloon with continuous fibers that are applied to a base balloon by rotary delivery using an automatic applicator. The fibers may be impregnated or coated with an adhesive prior to or during application. But this approach can slip and fail as the balloon cone fibers are rotationally delivered. Chinese patent No. CN111991681a (publication No. CN 202010882300.2) discloses an inflatable medical balloon with continuous fiber winding, the fiber being applied by rotating around the balloon radial axis using a mandrel with the fiber. However, this approach increases the thickness of the balloon, reduces the compliance and passability of the balloon, and results in an increased outer diameter of the balloon after folding, which is detrimental to the passage of highly stenosed lesions.
In summary, the tapered fibers of existing inflatable medical balloons tend to slip off during rotational delivery, while the outer diameter of the profile increases after folding.

In view of the above, the invention provides a fiber winding balloon and a preparation method thereof, which can solve the problem that the cone fiber of the existing inflatable medical balloon is easy to slip during rotary delivery, and the outer diameter of the profile after folding can be increased, so that ultrahigh burst pressure can be obtained.
