A stent having a primary strut and at least two secondary struts. The primary strut includes at least first and second members slidably attached together so as to be able to shorten and/or elongate the overall length of the primary strut. A distal end of one secondary strut may be attached to a distal end of the first or second primary strut member. A proximal end of a secondary strut may be attached to a proximal end of the other primary strut member. Any ends of secondary struts that are not attached to the first or second primary strut members may be joined together. Methods of delivering such a stent and collapsing and withdrawing such a stent are also disclosed. |
