A balloon catheter suitable for longer vascular lesions
By designing a balloon catheter suitable for longer vascular lesions, adopting a first balloon and a second balloon structure with a proximal end larger than a distal end, combined with a sliding ring and a sealing connecting membrane, the problem that balloon catheters in the existing technology are difficult to adapt to changes in blood vessel diameter is solved, and better fitting and surgical effects are achieved.

AI Technical Summary
Existing balloon catheters have difficulty adapting to the difference in diameter between the proximal and distal ends of the blood vessels when treating longer vascular lesions, resulting in the proximal end expanding to the required size and the distal end over-expanding or expanding to the required size, which can easily lead to vascular damage or restenosis.
A balloon catheter is designed, comprising a first balloon whose proximal diameter is larger than the distal diameter and a second balloon coated thereon. By providing a penetrating inner cavity and a connecting channel, and utilizing a sliding ring and a sealing connecting membrane, the first and second balloons can achieve coordinated expansion and deformation to adapt to changes in blood vessel diameter.
It improves the fit between the balloon and the blood vessels, reduces the risk of blood vessel damage, and improves the success rate and safety of the operation.
