Abstract
A dilation device comprises an elongate shaft, an inflatable balloon, and a resilient tube. The inflatable balloon is disposed along the shaft. The resilient tube is also disposed along the shaft and is positioned to encompass at least part of the inflatable balloon. The resilient tube is configured to impose an inwardly directed resilient bias on at least a portion of the exterior of the inflatable balloon. At least part of the resilient tube is secured to one or both of the elongate shaft or the inflatable balloon.
