the flap compression section 16 once the balloon is positioned in the flap forming section 12 the balloon is inflated and deflated as described above the balloon wrapping tool is then advanced proximally relative to the catheter 20 until the balloon 20 is in the flap wrapping section 14 and finally in the flap compression section 16 once the balloon is successfully formed wrapped and compressed the balloon wrapping tool 10 is slid distally off the distal end of the catheter 22 in another illustrative embodiment the balloon wrapping tool 10 is advanced in a distal direction down the shaft of the catheter and over the balloon in accordance with this embodiment and referring to fig1 the balloon wrapping tool 10 can be provided in a coaxial arrangement with a catheter shaft 32 and releasably secured to a manifold 36 of the catheter 30 the flap forming section 12 is positioned distal of the flap wrapping section 14 and the flap wrapping section 14 is positioned distal of the flap compression section 16 relative to the catheter 30 in this configuration and after the balloon 34 has been inflated during a medical procedure and subsequently withdrawn proximally from the body the balloon wrapping tool 10 is released from the manifold 36 of the catheter.
