Claim Text:
1. A medical device, comprising: an elongate support structure; and an inflatable balloon, the balloon comprising a first-end portion secured to the support structure at a first location, a second-end portion secured to the support structure at a second location distal to the first location, and a middle-body portion, the middle-body portion having a first end integrally formed with or otherwise bonded to the first-end portion, and a second end integrally formed with or otherwise bonded to the second-end portion, the first-end portion having a wall thickness greater than a wall thickness of the middle-body portion, the respective first-end portion, middle-body portion and second-end portion collectively defining a sealed interior of the balloon through which the support structure extends, the balloon being stretch-mounted to the support structure so as to be in tension relative to the support structure, wherein the balloon is formed in a diamond shaped configuration that transitions to a substantially spherical configuration when the balloon is inflated to an inflation pressure that is at least about ten percent greater than atmospheric pressure external to the balloon, such that the balloon, when inflated to the inflation pressure and anchored in an anatomical body region, resists movement of the support structure relative to the balloon.
