Abstract:
An implantable retainer, deliverable via an elongate tubular delivery device for retaining vaso-occlusive device in an aneurysm, comprising:(a) a core wire having a proximal end and a distal end,(b) a joint extending between the distal end of the core wire and at least one interior array element, said joint being electrolytically severable upon application of a suitable current to said joint, said joint being comparatively more susceptible to electrolytic severability than said core wire and said at least one interior array element, and(c) a retainer assembly comprising said at least one interior array element, said retainer assembly having a first delivery shape when retained within said elongate tubular delivery device and having a distal delivery end and a proximal delivery end, and a second deployed shape, different than first delivery shape, when said retainer assembly is not retained within said tubular delivery device and having a distal deployed end and a proximal deployed end, said at least one interior array element extending outwardly from said joint in said second deployed shape configured to be disposed within said aneurysm, and wherein after electrolytic severance from said core wire, said retainer assembly includes a residual joint.
