Abstract
a dilatable balloon catheter, comprising: a guide wire inserted and disposed in the inside of the catheter, an operation portion is fixedly connected to one end of the catheter, a balloon is disposed at the outer side of the catheter remote from the operation portion, the lumen of the catheter and the inner cavity of the balloon are connected by a communication structure provided on the catheter, the guide wire includes a first guide wire and a second guide wire which are separated from each other, the rear end of the first guide wire is connected to insertion-extraction structure in the rear end of the operation portion, the second guide wire is fixed to the inside of the catheter by a fixing process. The guide wire of the dilatable balloon catheter and the liquid injection lumen can share the same lumen, greatly reducing the diameter of the catheter in the present invention, so that the dilatable balloon catheter can be inserted into a narrow duct or lumen that needs to be expanded in human body through an device channel of an endoscope, and realize visualization operation.
