1. A delivery and detachment system for an implantable intravascular device, the system comprising:
an inner support tube having a passageway extending in an axial direction from a proximal end to an opposite distal end; and
a securement wire extending through the passageway of the inner support tube;
an intentional friction zone imposes a controlled friction force on the securement wire; the intentional friction zone is located anywhere between the distal end of the inner support tube and a midway point between the respective proximal and distal ends of the inner support tube;
an outer sleeve surrounding an outer surface of the inner support tube, wherein the outer sleeve is made of a reflowable material; wherein the inner support tube has defined therein at least one radially inward side port opening intersecting with the passageway; and the reflowable material of the outer sleeve is present in the at least one radially inward side port opening defined in the inner support tube and is present in the passageway of the inner support tube forming an associated point of direct physical contact with the securement wire.
