Claim:
1. A balloon catheter system having an intussuscepting balloon said catheter system comprising: an outer conduit; an inner conduit, suitable for passage over a guide wire, said inner conduit is disposed within the lumen of said outer conduit such that the longitudinal axes of said inner and outer conduits are substantially parallel, said inner conduit is positioned such that a distal tip of said inner conduit extends beyond a distal tip of said outer conduit, wherein said inner conduit is adapted for being moved along its longitudinal axis in relation to said outer conduit; an inflatable balloon having a balloon diameter and a balloon length, the proximal end of said balloon is sealingly attached to the outer surface of the distal tip of said outer conduit and the distal end of said balloon is sealingly attached to the outer surface of the portion of said inner conduit that extends beyond the distal tip of said outer conduit, wherein the distal end portion of said balloon is adapted for intussuscepting upon proximal movement of said inner conduit in relation to said outer conduit, said balloon is selected from a plurality of different balloons each having a unique combination of balloon length and balloon diameter; and a handle adapted for moving said inner conduit proximally within said outer conduit and for removing a volume of an inflation fluid from said balloon into an expandable chamber in said handle when said balloon is being intussuscepted in an inflated state such that during the intussuscepting of said balloon the pressure within said balloon and said expandable chamber remains substantially unchanged, said handle includes, a housing having standard dimensions, a hollow fluidic system disposed within said housing, said fluidic system includes a first end sealingly attached to said outer conduit and a second end sealingly attached to a hollow drawing member, said fluidic system also includes a fluidically sealable fluid port for introducing inflating fluid into said balloon through a space formed between said inner conduit and said outer conduit and for withdrawing said inflating fluid from said balloon through said fluidic system, a hollow plunger assembly movably disposed in said housing, said plunger assembly includes a hollow plunger rod surrounding said inner conduit and attached thereto, said hollow plunger rod is sealingly and movably disposed within said hollow drawing member to form said expandable chamber, said hollow drawing member is selected from a plurality of non-standard hollow drawing members having different inner diameters such that the inner diameter of said hollow drawing member is matched to the diameter of said balloon, said hollow plunger assembly also includes a gasket attached to said hollow plunger rod and sealingly disposed within said hollow drawing member and having a gasket diameter, said gasket is selected from a plurality of different gaskets such that the diameter of said gasket matches the inner diameter of said hollow drawing member, said inner conduit is attached to said plunger assembly, said plunger assembly is adapted to be partially pulled out of said housing to longitudinally proximally move said inner conduit within said outer conduit for intussuscepting said balloon and to expand said expandable chamber for accommodating inflating fluid ejected from said balloon during the intussuscepting thereof, and a locking mechanism movably disposed within said housing for controllably enabling and disabling the moving of said inner conduit within said outer conduit and the moving of said plunger assembly within said hollow drawing member, said locking mechanism is selected from a plurality of differently sized non-standard locking mechanisms to match said length of said balloon.
