Abstract
A coiled stent ( ) has a coiled stent body with a main body portion ( ) and end portions ( ). The end portions may be substantially less stiff than the body portion to help prevent tissue trauma. A graft material ( ) may be used to cover at least the main body portion to create a coiled stent graft ( ) in which adjacent turns ( ) have gaps defined therebetween to create a generally helical gap ( ). The coiled stent may have side elements ( ) separated by connector elements ( ) and be placeable in a contracted, reduced diameter state and in a relaxed, expanded diameter state. The connector elements are preferably generally parallel to the stent axis when placed in the contracted, reduced-diameter state, typically tightly wrapped around a placement catheter ( ).
