Description
Technical Field
The present application relates to balloon dilation catheters, and more particularly to balloon dilation catheters that can be reused multiple times.
Background
Currently, balloon catheters originate in the 60 s of the 20 th century. In 1963, dotter was successful in performing abdominal aortic angiography through stenosed iliac arteries with inadvertent distal arterial catheterization, suggesting that this approach could be used to guide the catheter using a flexible guidewire to directly and gradually dilate stenosed arteries. PTA was successfully performed on patients with severe arterial stenosis of the lower extremities by the first application of coaxial catheters (coaxial catheters) by Dotter et al in 1964. A bare metal stent phase, a drug eluting stent phase, and an emerging fully degradable stent phase then occur. Although the stent has been initially substituted for pure PTA balloon expansion, a PTA balloon catheter must be used for pre-expansion before stent implantation, and thus PTA balloon catheter pre-expansion is an essential treatment tool for stent implantation.
The existing PTA product mainly comprises the structure as shown in fig. 1: the balloon 1 can form three or more petals by the flaps, which are shown in fig. 2 and 3, so that the size of product insertion can be reduced to a great extent, and the balloon can conveniently pass through a narrow lesion position. After the product enters the blood vessel to pass through the lesion position, the saccule is inflated and expanded, and then the pressure is relieved and withdrawn, or the product is placed at other lesion positions to continue to expand.
After the balloon is expanded and depressurized, the product is difficult to recover to the original shape and size, and often, two flat petals are formed, so that the shape of the balloon is much larger than the size of the original petals, the difficulty of recovering the product into a sheath tube is increased, the difficulty of passing through lesion positions when the product is used for expanding other lesions is also increased, and the repeated expansion capacity of one product to more lesions is lost. For multiple lesions or longer lesions it may be necessary to increase the amount of consumable product, increasing the economic burden on the patient.
