A ureteric balloon catheter is a balloon catheter intended for treating strictures of the ureter. In fact it is a double J stent on which a balloon is mounted. It is connected to a delivery device to introduce it from the bladder into the ureter.The system comprises a non-return valve device, and a pusher with a stylet and two ports.
The side port is for injecting contrast agent to inflate the balloon, while the straight port is for the guidewire. The catheter has a relatively large-diameter central lumen and a shaft of 2 mm. The balloon is in two sections: a long narrow section or shaft and a larger cranial bulb. The larger cranial bulb prevents distal migration, while the longer narrow section maintains the increased diameter of a predilated stricture in the ureter section.
