A removable stent (10) has guide member pairs (16) and loops (20), the guide member pairs being used to align arms of a framework (28) which may expand or collapse the stent. The stent can be retained inside an outer sheath (30) of a catheter (32) with a collapsible filter net (34). Magnetic stents and stents with springs (170) and hinges (156) are also provided.
