Described herein is a balloon catheter with a zero-profile tip—that is, a balloon catheter having a distal tip that does not extend beyond the boundary of the cavity that will be created by the balloon when inflated—and further described herein are methods for the manufacturing of same. Several embodiment feature a method for inverting the distal end of an inflatable balloon structure, said inflatable balloon structure having a middle region, a first end region with a first opening, and a second end region with a second opening, said method comprising: (1) centrally inverting the second end region of the inflatable balloon structure and passing it through the first opening (2) permanently fixing the inverted second end region to prevent un-inversion and (3) returning the second end region back through the first opening.
