1. A catheter balloon comprising at least one balloon material and at least one integral non-distending region comprising a plurality of layers which wind around the balloon material and overlap to form an angle of between 0 and 90 degrees relative to each other upon inflation at an angle that reduces the compliance of said region.

13. A balloon catheter comprising a catheter shaft and a catheter balloon comprising at least one balloon material and at least one non-distending region comprising a plurality of elastomer-imbibed polytetrafluoroethylene layers which wind around the balloon material and overlap to form an angle of between 0 and 90 degrees relative to each other upon inflation and retain pressure in the balloon.

14. A method of forming a continuous integrated seal on an inflatable balloon comprising:
-
a. providing a first balloon material layer configured to form a desired balloon shape; b. wrapping a wrap layer around said first balloon material layer; c. changing angle of the wrap to wrap at least one layer at an angle sufficient to create a seal over the first balloon material layer; d. wrapping a second balloon material layer around the seal to increase the bonding surface area of the seal; and e. forming an integrated non-distensible region upon inflation.

15. A method of forming a continuous exposed integrated seal on an inflatable balloon comprising:
-
a. providing a balloon material layer configured to form a desired balloon shape; b. wrapping at least two layers of a wrap around said first balloon material layer; c. changing angle to wrap one layer at an angle to the next layer sufficient to create a seal over a first balloon material layer; and d. forming an integrated non-distensible region on an inflatable balloon.

16. A method of forming a discontinuous non-exposed integrated seal on an inflatable balloon comprising:
-
a. providing a first balloon material layer configured to form a desired balloon shape; b. wrapping at least one layer of a second wrap around said first wrap at an angle sufficient to create a seal over a first balloon material layer; c. wrapping a second balloon material layer around the seal to increase the bonding surface area of the seal; and d. forming an integrated non-distensible region in an inflatable balloon.
