Abstract

The invention relates to a new and improved intrauterine contraceptive device (IUD), which includes a fixing device to the fundal part of the uterine cavity, attached to members made in a material active into the uterine cavity, said members being attached the one behind the others, in a non-rigid assembly. The members are hollow members, open at both end and arranged in a sequence to form a longitudinal passage allowing passing through of a needle, and the fixing device to the fundal part of the uterine cavity is a thread affixed to the assembly of hollow members, provided with a retaining device in the uterine tissue, adapted for insertion by means of a needle. The invention relates also to a device for the insertion and the fixation of such an IUD to the uterine wall which comprises a needle for inserting the retaining device interlocked to the thread in the uterine tissue, a member for protecting the needle and receiving the IUD, and an actuating member for the needle, movable in relation the protecting member. The needle passes through the passage of the IUD to engage the retaining device in the uterine tissue, and the internal cross section of the member for protecting the needle and receiving the IUD corresponds substantially with the outer cross section of the hollow members of the IUD.
