Claim 9:
10. A vascular flow diverter system comprising:
a vascular flow diverter including a stent configured to transition from a collapsed configuration to an expanded configuration in response to the vascular flow diverter being deployed, the stent having a first porosity; and
a mesh cover surrounded by the stent, the mesh cover comprising:
an outer perimeter; and
an opening formed in a center of the mesh cover and located within the outer perimeter, the opening sized to allow a guide member to extend through the opening, the mesh cover, and the stent,

wherein the mesh cover extends at least partially around a circumference of the stent,
wherein the mesh cover is configured to conform to a shape of the stent, the mesh cover having a second porosity, the first porosity being greater than the second porosity, and
the system further comprising a delivery device comprising a lumen receiving the vascular flow diverter, the delivery device comprising:
a microcatheter comprising a tubular outer wall, a distal end, and a proximal end, the distal end comprising a transverse opening and a longitudinal opening, where the transverse opening is perpendicular entirely along a cross-section of the distal end to a longitudinal axis of the microcatheter and the longitudinal opening is substantially parallel to the longitudinal axis of the microcatheter, and the longitudinal opening intersects the transverse opening;
a guide member comprising a distal section, a proximal section, and a junction between the distal section and the proximal section, wherein:
the distal section has a smaller cross section than the proximal section;
the distal section is steerable from a proximal end of the proximal section, where at least a portion of the distal section of the guide member is configured to adopt a curved configuration; and
the junction is configured to push the vascular flow diverter; and
a pull wire is positioned in a lumen of the guide member and terminates at a tip of the distal section,

wherein a proximal end of the pull wire may be pulled to form the curved configuration in at least a portion of the distal section, and
wherein the distal section of the guide member is sufficiently contiguous to contain, when the pull wire is pulled to form the curved configuration in the distal section, an entire length of a portion of the pull wire extending from the tip of the distal section, through the distal section, and to the junction.
