An implant delivery system comprising a catheter including at least one lumen, an implant configured to be received in the lumen, and a latching mechanism configured to be received in the implant. The method includes the steps of providing a ribbon of labels and folding the ribbon of labels so as to form at least one folded portion. Optionally, a fuse element can also be added to the internal circuit data line that would prevent both internal and external access to the stored data. In the sub-group of cells at least one second cell intended for the storage of information concerning the programmed or erased state of the same page is provided. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent. One embodiment of the invention has a monolithically integrated delay loop utilizing one or more asymmetric couplers.
