Claim 13:
14. A system comprising:
a core assembly;
a tubular sheath; and
a generally tubular structure disposed on the core assembly, wherein the tubular structure is formed of a plurality of braided strands, at least some of the strands having a cross-sectional diameter of no more than 0.001 inches, and wherein the tubular structure has:
a number of pores between the strands, the pores being sized to have a flow- diversion effect with respect to a cerebral aneurysm when the tubular structure extends across the aneurysm,
a compressed state when the tubular structure is positioned within the tubular sheath,
an expanded state in which the tubular structure has an expanded state diameter and is at a full expansion distance of 14 mm or less, the full expansion distance corresponding to a longitudinal unconstrained distance at which the distal end of the tubular structure attains the expanded state diameter, wherein, in the expanded state, the tubular structure extends in a single direction along the full expansion distance,
wherein at least a portion of the tubular structure remains within the tubular sheath at the full expansion distance.
