Abstract
The utility model discloses a balloon conduit which solves the technical problem that tensile force to original guide wires can be eliminated when a balloon is expanded, thereby preventing the balloon from generating a 'banana-shaped' balloon during the expanding process. In order to solve the technical problem, the balloon conduit adopts the following technical solution that a balloon conduit is connected to a far end pipe body through a smooth transition segment from a near end pipe body, and therefore, the far end pipe body comprises a nylon outer pipe, a pipe-shaped sharp end, a balloon and an original guide wire which is arranged outside the balloon and is connected with the pipe-shaped sharp end, and an intelligent wire knitting structure which is used for releasing tensile force and is composed of a spring or a rotary shaving pipe is connected among the near end pipe body and two ends of the original guide wire. The balloon conduit can help a balloon to still keep the straight state of the balloon when being expanded. When the balloon is pressurized and expanded, the spring or the rotary shaving pipe can be forced and extended, thereby eliminating the generation of a banana-shaped balloon, and the spring or the rotary shaving pipe is to be shortened to the original state when the balloon is decompressed or exhausted.
