A method and apparatus are provided for loading an intrauterine contraceptive device into the barrel of an inserter. The device includes an apertured tubular section having a closed end section at one end. The closed end defines an enlarged chamber. The device has a stem, a flexible arm generally transverse to the stem, and an enlarged head at one end of the stem. The device is receivable in the instrument when the stem is partially disposed within the barrel and the barrel is displaced forwardly until the head is received in the chamber. The head engages the shoulder that is defined between the aperture and the chamber in the instrument, thereby to retain the device in the instrument when the barrel is withdrawn. The device is removable from the instrument when the barrel is inserted again into the instrument to dislodge the head from the shoulder so that the barrel can be withdrawn together with the device. |
