Abstract

Novel polymer shrink tubes, such as fluoropolymer shrink tubes and novel uses thereof. The polymer shrink tubes include at least one three-dimensional pattern formed along at least a portion of the inner surface of the tube. The polymer shrink tubes can be used for, for example, embossing a pattern into a polymer tube. Further use includes, for example, forming a catheter with at least one channel located in the catheter wall.
