Claim:
A non-compliant medical balloon, where the balloon may be changed from a deflated state to an inflated state by increasing the internal pressure within the balloon, and when the balloon is fully inflated, it has a length and diameter that do not substantially change as the internal pressure further increases, the balloon comprising: a balloon layer having an outer surface, the balloon layer including a base layer, a first reinforcing layer and a second reinforcing layer; the base layer being formed of a polymer material; the first reinforcing layer disposed over the base layer, the first reinforcing layer being one of either a plurality of discrete inelastic fibers oriented substantially parallel to the long axis of the balloon and a first sheet of textile fabric material, the textile fabric material being one of a woven, knitted, braided and non-woven fabric; the second reinforcing layer being applied at least partially over the first reinforcing layer, the second reinforcing layer being one of either at least one inelastic fiber wrapped around the circumference of the balloon substantially transverse to the long axis of the balloon and a second sheet of textile fabric material, the textile fabric material being one of a woven, knitted, braided and non-woven fabric; at least one of the first and second reinforcing layers being one of the first and second sheet of textile fabric material; and at least one longitudinal strengthening rod connected to the outer surface of the balloon layer.
