Abstract: The methods and devices disclosed herein promote temporal control of balloon inflation patterns. The devices include a covering for a portion of the balloon that compresses the balloon portion during the inflation process. This enables the distal portion of a balloon to be inflated prior to the proximal portion of a balloon, creating a tapered shape at lower inflation pressures. This is especially useful during transvascular implantation procedures, as it prevents dislodgement of an implant mounted on the balloon. As inflation continues, pressure exerted on the balloon by the covering is overcome such that the proximal region of the balloon inflates, forming a shape with generally straighter sides than the tapered shape, thereby expanding the cardiovascular device.
