1. An occlusive vascular device comprising
a molded or extruded shape memory polymer material that is formed
in a pre-deployed state as a monolithic, non-wound elongate member configured for delivery via a catheter and having
a first interlocking structure formed of the same shape memory polymer material as part of the elongate member on a distal end thereof; and
a second interlocking structure formed of the same shape memory polymer material as part of the elongate member on a proximal end thereof and configured to engage with an interlocking structure on another of the occlusive vascular device of a same shape as the first interlocking structure to form a gapless joint to enable linking of two of the elongate members together in succession; and
in a deployed state as a coiled member, which coils from a form of the elongate member.
