INSERTER

1 . A kit comprising:

an intrauterine system comprising:

a reservoir containing a hormone, and

a removal string attached to the intrauterine system; and

an inserter comprising:

an insertion tube configured to retain at least a portion of the intrauterine system;

a handle coupled to the insertion tube and configured to contain the removal string wholly therein, the handle comprising:

a longitudinal opening;

a lock arranged inside the handle and configured to reversibly immobilize the removal string within the handle prior to insertion into a uterus; and

a slider coupled to the insertion tube and configured to be moved within the opening of the handle, wherein movement of the slider releases the removal string and intrauterine system inside the uterus.

2 . The kit of claim 1 , wherein the handle further comprises a plunger having a hollow configuration for allowing passage of the removal string therethrough.

3 . The kit of claim 1 , wherein the handle further comprises a first end having a channel configured to allow passage of the insertion tube therethrough and a second end having a closed configuration.

4 . The kit of claim 1 , wherein the inserter is configured for positioning the intrauterine device within the uterus without manual handling of the removal string.

5 . The kit of claim 1 , wherein the inserter is configured for positioning the intrauterine device within the uterus with one hand.

6 . The kit of claim 5 , wherein the slider is configured to be movable within the longitudinal opening using a single digit of the one hand.

7 . The kit of claim 1 , wherein the hormone is levonorgestrel.

8 . The kit of claim 1 , further contained within a sterilized package.

9 . The kit of claim 1 , wherein the intrauterine system is a T-shaped intrauterine system.

10 . The kit of claim 9 , wherein the T-shaped intrauterine system comprises two wings, and wherein the wings remain partly uncovered by the insertion tube, while the wings still remain together when the intrauterine system is substantially covered by the insertion tube.

11 . The kit of claim 1 , wherein the reservoir is covered by a membrane or wherein the membrane comprises a siloxane based elastomer.

12 . The kit of claim 11 , wherein the siloxane based elastomer is polydimethylsiloxane.

13 . The kit of claim 1 , wherein the reservoir essentially consists of an elastomer and levonorgestrel.

14 . The kit of claim 13 , wherein the elastomer is polydimethylsiloxane.

15 . The kit of claim 1 , wherein the reservoir is inside a first end of the insertion tube, and the slider is attached to a second end of the insertion tube.

16 . The kit of claim 15 , wherein the first end of the insertion tube comprises a flexible material and is configured to conform to the anatomy of the uterus.

17 . The kit of claim 1 , wherein the inserter further comprises an adjustable flange arranged on the insertion tube, the adjustable flange is used to mark a depth of a uterus.

18 . The kit of claim 1 , wherein the lock comprises an object configured to prevent or allow movement of the removal string by at least partly moving or pivoting from a first position to a second position.

19 . The kit of claim 18 , wherein the lock further comprises a counterpart against which the removal string is pressed by the object and thus reversibly immobilized in a locked position.

20 . The kit of claim 1 , wherein the lock is rotatably mounted inside the handle.

21 . The kit of claim 18 , wherein movement of the slider presses a part or extension of the slider or of the insertion tube against the object or an extension thereof thus changing its orientation and releasing the removal string.

22 . The kit of claim 1 , wherein the lock comprises:

a main part;

an extension of the main part having an abutment surface; and

a counterpart adapted to form a blocking together with the main part, wherein the lock is rotatably mounted inside the handle.

23 . The kit of claim 18 , wherein the object comprises an opening or a slot in a diagonal direction through essentially the whole diameter of the object, adapted to receive the removal string.

24 . The kit of claim 1 , wherein the lock comprises:

a main part;

a first extension of the main part having an abutment surface;

a second extension of the main part having a wedge-like shape; and

a counterpart,

wherein the second extension is adapted to form a blocking together with the counterpart and the lock is rotatably mounted inside the handle.

25 . The kit of claim 24 , wherein the main part has essentially the shape of a cylinder or is of a triangular shape.

26 . The kit of claim 24 , wherein the slider comprises an extension adapted to abut the abutment surface.

27 . The kit of claim 1 , wherein the lock comprises:

a main part;

a first extension of the main part; and

a second extension of the main part,

wherein the first and section extension are arranged in a first position of the slider to be essentially in contact with each other to form a blocking, and

wherein movement of the slider to a second position separates the first and section extensions from each other.

28 . The kit of claim 1 , wherein the lock comprises:

a first locking part and a second locking part movably mounted inside the handle and arranged in a first position of the slider to be essentially in contact with each other to form a blocking; and

a first protrusion and a second protrusion arranged inside the handle,

wherein the first and second protrusions are arranged to move the first and second locking parts in response to movement of the slider to a second position.

29 . The kit of claim 1 , wherein the lock comprises a knot in the removal string or a mechanical hindrance attached to the removal string.

30 . The kit of claim 1 , wherein the lock comprises welding, gluing, or adhesion of the removal string to the inserter.
