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 having a longitudinal opening, the longitudinal opening having a first end and a second end, the handle comprising a slider arranged in the longitudinal opening, the slider being movable and having a first end and a second end;
a plunger attached to the handle;
an insertion tube attached to the slider; and
a lock arranged inside the handle and comprising an object and an extension, the lock adapted to reversibly lock the intrauterine system in relation to the plunger via a removal string by the object pivoting and pressing the removal string against the extension to immobilize the removal string.

2. The inserter of claim 1 , wherein the plunger is hollow and a forward end of the plunger includes at least one of a notch, an indentation, an eyelet, a funnel, and a groove.

3. The inserter of claim 1 , wherein the slider comprises at least two elements that are combined on at least one point by a transversal member and the transversal member is a knob or a switch.

4. The inserter of claim 1 , wherein the handle includes at least one element to connect to the slider and the element includes at least one of a support, a shoulder, a holder, a saddle, a groove, or a slot.

5. The inserter of claim 1 , wherein the lock is mounted on the handle.

6. The inserter of claim 1 , further comprising an adjustable flange that is used to mark a depth of a uterus.

7. The inserter of claim 1 , wherein the lock immobilizes the removal string responsive to the first end of the slider moving to a first end of the handle.

8. The inserter of claim 7 , wherein the lock releases the removal string responsive to the second end of the slider moving towards the second end of the handle.

9. The inserter of claim 1 , wherein the object forms a slot or pinhole through which the removal string of the intrauterine system runs.
