a base (20) having a floor (22) with a delatcher (26), an outside of the base (20) having a collar (29);
a navigator (50) having an aligner plug (51A), two mirror symmetrical fences (52) along an entire length of the navigator (50), joining together atthe operator end (6), thereby forming a slot (56) with a divergence (55);
an open converger (40) having a flange (45), a covered channel (41) commencing with a circular opening (41a) and transitioning to a funneling opening (41b) symmetrical about an imaginary orthogonal plane passing through a line X-X′, the funneling opening (41b) diverging to two dome shaped openings (43), a reversibly collapsible projections pair (44), an alignment socket (51B);
a driver assembly (60) having a bidirectional carrier (61), a graduated tube (71), and a latching rod (81); and
a gated support (90) having a leafy arm (91) and a downward fork (94) forming an inverted “U” gate (95) having sloped edges (97) with end points (96), at the other end, a holder (92) having an elongated grip (93) on either side;
wherein the reversibly collapsible projections pair (44) of the open converger (40) press-fits against corresponding receptacles (25) of the base (20), the aligner plug (51A) of the navigator (50) inserts in the alignment socket (51B) of the open converger (40), a lower end (37) of the stem (33) of the intrauterine device (30) sits on a conical seat (82) having two resting points (83) on the latching rod (81), while a knot (38) of the string (31) sits in a knot room (84) on the latching rod (81).
