Atherosclerosis is a disease that affects the systemic arterial system and directly threatens the patient’s life.

With the improvement of the overall living standards of our people and the aging of the population, the incidence of atherosclerosis is increasing. Atherosclerosis is a disease that affects the systemic arterial system and directly threatens the patient’s life.

Currently, there are three main ways to treat atherosclerosis: conservative treatment with drugs, surgery, and interventional surgery. Conservative treatment with drugs has shortcomings such as long cycle and poor efficacy. Traditional surgical operations have the disadvantages of large trauma, many complications, and long laser cutting hypotube periods, which are difficult for most patients to bear. Interventional surgery (arterial balloon dilatation surgery and stent implantation surgery) is a diagnostic and therapeutic operation that uses a series of interventional instruments and materials and modern digital diagnosis and treatment equipment; compared with traditional surgery, it only requires local anesthesia. It only requires a small opening of 1-2mm, so it has the advantages of less bleeding, less trauma, fewer complications, faster postoperative recovery, and safety and reliability, which can greatly reduce the pain suffered by the patient. Furthermore, balloon dilatation catheter treatment is reproducible. When blood vessels are restenotic, they can be expanded again through minimally invasive methods. In addition, even if the surgery fails, it has no significant impact on further stent or bypass surgery. Therefore, interventional surgery has gradually become the preferred method for treating arterial stenosis due to its advantages of minimal invasion, repeatable operation, and good efficacy.

For existing balloon dilation catheters, most of the distal welding processes involve welding and forming the inner tube, balloon part, and tip tube together. This process is cumbersome to assemble, has a low pass rate of finished products, and has low tip hardness. During use, if long-segment diffuse lesions are encountered, especially lesions with severe calcification, the balloon dilation catheter often cannot pass through the lesion smoothly due to insufficient catheter pushing force, and the catheter may even break within the blood vessel. The possibility of damage affects the surgical process and may even cause potential danger to the patient.

In order to achieve the above purpose, the technical solution adopted by Be-Cu Prototyping Inc and parts maker is:

A balloon dilation catheter includes a balloon body and an inner tube passed through the balloon body. One end of the balloon body is provided with a balloon tube leg connected to the inner cavity of the balloon body. The inner tube extends from the balloon tube leg. The inner tube extends to the outside and is fixed on the inner wall of the balloon tube leg. The end of the inner tube away from the balloon tube leg has a tapered structure with a tip facing outward.

Beneficial effects of the present utility model: the balloon dilation catheter provided by the utility model extends the inner tube from the balloon tube leg and is fixed to the balloon tube leg, so that the extended inner tube replaces the existing balloon dilation catheter. The tip tube material is made of the same material, and the outward end of the inner tube is constricted to form a tapered structure as the tip part. Therefore, the inner tube and the tip part formed by the tapered structure are made of the same material, and the coaxiality of the pushing process after entering the human body is more Good, it is more conducive to passing through narrow lesions and avoids the problem of breakage caused by insufficient pushing force.Be-Cu team brings process expertise, custom laser cutting equipment, and proprietary software to enable your next complex catheter or delivery system.
