Abstract

The present invention relates to an inserter for an intrauterine system comprising a handle ( 3 ), and an insertion tube ( 6 ) having a first end and a second end, and being arranged in connection with the handle. The inserter is characterized in that the first end of the insertion tube ( 6 ) comprises at least one frame slot for receiving a frame of the intrauterine system. The invention also relates to a kit comprising an inserter according to the present invention and an intrauterine system, wherein the intrauterine system ( 1 ) comprises a therapeutic component ( 1 b ) and a continuous, closed frame ( 1 a ), the therapeutic component ( 1 b ) being connected to the frame ( 1 a ) at least one point, and therapeutic component ( 1 b ) of the intrauterine system ( 1 ) is at least mainly arranged inside the first end of the insertion tube ( 6 ) and the frame ( 1 a ) of the intrauterine system ( 1 ) is at least mainly arranged outside the first end of the insertion tube ( 6 ).

First claim

The invention claimed is:

1. An inserter for an intrauterine system comprising
a handle ( 3 ), and
an insertion tube ( 6 ) having a first end and a second end, being arranged in connection with the handle, and the first end of the insertion tube ( 6 ) comprising at least one frame slot ( 21 ) for receiving a frame of the intrauterine system, characterized in that:
the handle ( 3 ) has a longitudinal opening ( 8 ), the longitudinal opening ( 8 ) having a first end ( 8 a ) and a second end ( 8 b ), and further comprising:
a movable slider ( 5 ) arranged in the longitudinal opening ( 8 ) and having a first end ( 5 a ) and a second end ( 5 b ),
a plunger ( 2 ) attached to the handle ( 3 ), the second end of the insertion tube being attached to the slider ( 5 ) and further comprising:
a lock adapted to reversibly lock the intrauterine system in relation to the plunger via a removal string of the intrauterine system, the lock being controllable by the slider ( 5 ), characterized in that the lock comprises a main part, an extension, and a counterpart, wherein the main part is rotatably mounted on the inserter, wherein the removal string is immobilized between the main part and the counterpart when the lock is in a locking position, and wherein the slider ( 5 ) presses against the extension to turn the main part around a shaft or an axle from a release position to the locking position.

2. An inserter according to claim 1 , characterized in that the first end of the insertion tube ( 6 ) comprises at least one connection slot ( 20 ) for receiving a connection part of the intrauterine system.

3. An inserter according to claim 1 , characterized in that the first end ( 8 a ) of the opening ( 8 ) and the first end ( 5 a ) of the slider ( 5 ) form a first pair of stop members, and the second end ( 8 b ) of the opening ( 8 ) and the second end ( 5 b ) of the slider ( 5 ) form a second pair of stop members.

4. An inserter according to claim 3 , characterized in that the first end ( 5 a ) of the slider is configured to be closer to a uterus during an insertion than the second end ( 5 b ) of the slider ( 5 ) and further characterized in that the locking position includes the first end ( 5 a ) of the slider ( 5 ) in contact with the first end ( 8 a ) of the opening ( 8 ) and the release position includes the second end ( 5 b ) of the slider ( 5 ) in contact with the second end ( 8 b ) of the opening ( 8 ) and the second end ( 5 b ) of the slider ( 5 ).

5. An inserter according to claim 4 , characterized in that the main part is turnable from the lock position to the release position.

6. An inserter according to claim 1 , characterized in that it further comprises a flange ( 4 ) arranged on the insertion tube ( 6 ).

7. An inserter according to claim 1 , characterized in that the first end of the insertion tube ( 6 ) comprises two diagonally symmetrical connection slots ( 20 ) for receiving a connection part ( 19 ) of the intrauterine system ( 1 ).

8. An inserter according to claim 1 , characterized in that the first end of the insertion tube ( 6 ) comprises two diagonally symmetrical frame slots for receiving the frame ( 1 a ) of the intrauterine system ( 1 ).

9. A kit comprising an inserter according to claim 1 and an intrauterine system, wherein
the intrauterine system ( 1 ) comprises a therapeutic component ( 1 b ) and a continuous, closed frame ( 1 a ), the therapeutic component ( 1 b ) being connected to the frame ( 1 a ) via at least one point, and
the therapeutic component ( 1 b ) of the intrauterine system ( 1 ) is at least mainly arranged inside the first end of the insertion tube ( 6 ) and the frame ( 1 a ) of the intrauterine system ( 1 ) is at least mainly arranged outside the first end of the insertion tube ( 6 ).

10. A kit according to claim 9 , characterized in that the therapeutic component ( 1 b ) is selected from the group consisting of a reservoir for active agent, a metallic wire and a combination thereof.

11. A kit according to claim 10 , characterized in that the reservoir essentially consists of an elastomer and an active agent.

12. A kit according to claim 10 , characterized in that the metal wire is made of copper.

13. An inserter according to claim 1 , characterized in that the main part is turnable from the lock position to the release position.

14. An inserter according to claim 1 , wherein the shaft or the axle is irregularly shaped.
