Claim 0:
1. A system comprising:
a delivery catheter; and
an expandable device implantable across an aneurysm in a cerebral blood vessel of a patient, the expandable device comprising:
a generally tubular sidewall 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, wherein the sidewall has a number of pores between the strands, and the pores are sized to have a flow-diversion effect with respect to an aneurysm when the sidewall extends across the aneurysm;
a compressed state in which the expandable device is positioned within the delivery catheter, the expandable device having a compressed state diameter corresponding to an inside diameter of the delivery catheter; and
an expanded state in which the expandable device 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 distance beyond a distal opening of the catheter at which the distal end of the expandable device attains the expanded state diameter, wherein, in the expanded state, the sidewall extends in a single direction along the full expansion distance,
wherein at least a portion of the expandable device remains within the delivery catheter at the full expansion distance.
