Balloon/delivery catheter assembly with adjustable balloon positioning

A balloon/delivery catheter assembly comprising:

• a balloon catheter having a distal balloon catheter end portion with an expandable balloon fluidly coupled to an inflation coupler, said balloon catheter having a first port proximal of said balloon and a second port distal of said balloon, and a balloon catheter lumen extending between said first and second ports;
• a delivery catheter having a polymeric delivery shaft with a delivery lumen extending between a proximal port and a distal port,
• said distal balloon catheter end portion being coaxially positionable with a friction fit and exterior to at least a portion of said polymeric delivery shaft;
• and
• a positioner having a positioner shaft and a positioner cuff and wherein said positioner shaft ends distally in said positioner cuff, and further said positioner cuff defines a positioner lumen such that said positioner cuff is coaxially slidable along at least a portion of said polymeric delivery shaft and is adapted to engage said distal balloon catheter end portion.
