Abstract: An expandable medical balloon comprising an inner layer formed of a polymer material having a first flexural modulus, an intermediate layer formed of a material having a second flexural and an outer layer formed of a material having a third flexural modulus, wherein the flexural modulus of the inner layer and outer layer is 50,000 psi to about 80,000 psi, the flexural modulus of the intermediate layer is about 130,000 to about 230,000 psi and the calculated burst strength of the balloon determined on a 90 degree bend in the balloon is about 35,000 psi or higher.
