A medical device, such as a stent, having a hollow portion formed from a fashioned filament (100, 110). Between adjacent segments of the fashioned filament is a detachable seam (140). After implantation of the device in the body, the device may subsequently be removed by grasping an end of the filament and pulling the end of the filament so as to detach the seam between adjacent segments of the fashioned filament, and unravel the hollow portion.
