1. A vaso-occlusive treatment system, comprising:
a delivery assembly; and
a vaso-occlusive device detachably coupled to the delivery assembly by a severable junction, the vaso-occlusive device comprising a proximal coil having an inner axial lumen and a proximal end portion coupled to the severable junction, and
a braid having a proximal end portion coupled to a distal end portion of the proximal coil by a first intra-device junction, the braid comprising a plurality of elongate braid members, wherein at least one of the elongate braid members extends proximally from the braid through the axial lumen of proximal coil and is secured to the proximal end portion of the proximal coil, respectively, to thereby form proximal coil stretch-resisting member,
wherein the proximal coil stretch-resisting member has a proximal end attached to a distal portion of the severable junction that is coupled to the proximal end portion of the proximal coil, the severable junction being configured such that the distal portion of the severable junction remains coupled to the proximal end portion of the proximal coil when the severable junction is severed, and
wherein a proximal end of each of the one or more elongate braid members that form the proximal coil stretch-resisting member comprises a respective hook that engages an aperture formed in the distal portion of the severable junction.
