Description

Balloon catheter with high supporting performance Technical Field The utility model relates to the technical field of balloon catheters, in particular to a balloon catheter with high supporting performance. Background Balloon catheter a flexible catheter for expanding a narrow opening or passageway in a body during catheterization. The deflated balloon catheter is placed and then inflated to perform the necessary procedure and then deflated again for removal, the balloon catheter typically has an inner tube, an outer tube, a balloon, a catheter hub, etc., and for more convenient handling of the balloon catheter in actual surgery, the balloon catheter typically needs to be used with a guidewire, so a guidewire port is provided at the balloon catheter. The Chinese patent publication No. CN221751965U discloses a balloon catheter, which comprises an inner tube, an outer tube and a balloon unit, wherein the outer tube comprises a first outer tube and a second outer tube fixedly connected with the first outer tube, and a guide wire port is formed at the interface of the first outer tube and the second outer tube fixedly connected with each other.
