Patent ID: 8216182

Claim:
An assembly with proximal and distal ends for bone, tissue and/or duct dilatation of a living being comprising in combination: (a) an inflatable and deflatable balloon element having a balloon interior; (b) a conduit defining a channel for accessing the balloon interior from a location outside a living body when the balloon is positioned inside the living body; (c) a balloon tensioning and/or balloon wrapping device for stretching the balloon element and/or folding, pleating or wrapping the balloon element to facilitate insertion and/or removal of the balloon element through a narrow diameter duct, access channel or cannula comprising a rod having proximal and distal ends extending through the channel to the balloon at the distal end of the rod; (d) a sealing gasket inside the proximal end of the channel having a centrally-located aperture to accommodate the rod, whereby under compression the sealing gasket forms a fluid-tight seal of the channel; and, (e) a rod control element connected to the proximal end of the rod whereby the rod can be moved in a proximal or distal direction and/or rotated from a location outside the conduit.
