    Patent 5,785,053
    Issued: July 28, 1998
    Inventor(s): Macandrew; John & Conway; John & Paton; Michael & Gardner; Richard & Rauramo; Ilkka & Lehtinen; Matti
    Assignee(s): Leiras Oy
    An inserter for the positioning of an intrauterine device in the uterus, which inserter includes a plunger, a handle attached to the plunger, a string for the removal of the IUD, a locking device to lock the string in such a way that the IUD remains immobile in relation to the plunger, and a protective tube around the plunger. The protective tube is arranged in relation to the plunger in such a way that it can be pushed, at the forward end that goes into the uterus, past the plunger at distance (L) , which corresponds substantially to the length of the IUD assembled for insertion. The stop members ensure that the front edge of the protective tube is stopped in a configuration in which the hemispherical tips of the wings of the transverse member of a T-shaped IUD remain partly uncovered by the protective tube, but the wings nevertheless remain pressed against each other.

RLDA Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA). By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart.
