Claim 18:
19. A method of making an embolic device, the method comprising:
constraining an intermediate section of a tubular braid in a substantially closed configuration, the tubular braid including a first section having a first porosity and a second section having a second porosity that differs from the first porosity;
inverting the tubular braid to produce a dual-layer tubular section comprising the first section overlapping the second section, the dual-layer section having a substantially closed end at the intermediate section, an open end opposite the substantially closed end, and a cavity radially bound by the dual-laver section;
inserting a form within the dual-layer section through the open end such that the form is positioned axially between the substantially closed end and the open end and such that the form is positioned within the cavity of the dual layer section; and
setting a device body shape based on the form.
