摘要： An expandable stent prosthesis is disclosed in which the apices of the bends located at at least one end of the stent are individually twisted at an angle to the circumference of the stent to form a fan blade-like arrangement when viewed from that end. The fan blade-like arrangement allows the stent to expand from the compressed condition during deployment such that likelihood of a strut or bend of the stent become entangled with a barb or adjacent strut or bend, is reduced. In one embodiment of the invention, the fan blade-like arrangement results from plastically deforming the individual apices, while in another embodiment, the apices are twisted into the fan blade-like arrangement during the loading process, such as by use of a suture thread to pull the apices into alignment.
