1. A method for sacrospinous ligament fixation, the method comprising the steps of:
(a) providing a kit comprising (i) an apparatus comprising: (A) an elongated needle, (B) a superelastic anchor disposed within said elongated needle, (C) a securing element, and (D) a user-triggerable advancement mechanism, and (ii) a retrieval device comprising a distal tube section having an inner diameter smaller than an uncompressed uncontracted diameter of the anchor such that a proximal withdrawal of the anchor into the distal tube section is effective to radially contract the anchor to a contracted state;
(b) vaginally introducing said elongated needle and sequentially piercing a vaginal wall and penetrating a sacrospinous ligament with a distal end of said elongated needle;
(b) ejecting the superelastic anchor out of the distal end of said elongated needle from within said elongated needle such that said superelastic anchor extends distally outward from the longitudinal axis of the needle, into the sacrospinous ligament;
(c) withdrawing said elongated needle to a position proximal to the vaginal wall; and
(d) ejecting said securing element from the apparatus against a proximal portion of the vaginal wall, to prevent a movement of the anchor in at least one direction,
thereby affixing the vaginal wall against the sacrospinous ligament.
