Abstract
A fiber-reinforced device, such as an inflatable medical balloon, includes a cylindrical central portion (1301). The balloon includes first and second tapered or conical end portions (1303a,1303b) connected to the cylindrical central portion along a central longitudinal axis extending from a first end of the balloon to a second end of the balloon. In one embodiment, the balloon includes a single continuous fiber (1313a) running substantially parallel to the longitudinal axis along the central portion and radially around a portion of the end portions, or both. The balloon comprises a second fiber (1315) extending radially around the central portion of the balloon, which may be part of the single continuous fiber. Related methods are described.
