Protruding from 5 an interior surface of the non-planar heating chamber is a detachment fiber made from a polymeric material and having a closed distal end. At least one heating element is disposed on the interior surface of the non-planar heating chamber to produce sufficient heat to sever the detachment fiber. An articulation point is established between the vasooccluding device and the delivery system. The vaso-occluding device remains at all 10 times substantially self-centered while being advanced. 2991514vl1/3 7 A ( ~f) LL Zfl Zn K~t~ K / Zn 3~t' k~~s , ZN 0 / 4$?'
