The disclosure is related to an endoprothesis, such as a stent. The disclosure also relates to a support structure for an endoprothesis and methods of delivering such an endoprothesis as well as a method of manufacturing a support structure. Furthermore, the disclosure provides an improved positioning of an endoprothesis and overcomes the folding issues and thus improves the flow through a body vessel. One embodiment provides a tubular support structure for avoiding folding of an endoprothesis, such as a stent or a valve, comprising one or more first circumferential zigzag patterns, at least two second circumferential zigzag patterns and wherein the first and second circumferential zigzag patterns are overlapping.
