Abstract

The invention relates to an inserter for an intrauterine system, comprising a handle ( 3 ) having a longitudinal opening ( 8 ) at its first end, said opening ( 8 ) having a longitudinal axis parallel to the longitudinal axis of the inserter, a first end ( 8 a ) and a second end ( 8 b ), a moveable slider ( 5 ) arranged in said longitudinal opening ( 8 ) and having a first end ( 5 a ) and a second end ( 5 b ), a plunger ( 2 ) attached to the handle ( 3 ), an insertion tube ( 6 ) arranged around the plunder ( 2 ) having a first end and a second end, with its second end attached to the slider ( 5 ), wherein the inserter further comprises locking means for reversibly locking the intrauterine system in relation to the plunder ( 2 ) via a removal string of the intrauterine system, said locking means being controllable by the slider ( 5 ) and/or the insertion tube ( 6 ).

First claim

1 . A method of providing contraception in a patient, comprising:
(a) providing an intrauterine system having a reservoir containing a hormone and a removal string attached to the intrauterine system; (b) holding an inserter in one hand, the inserter comprising:
a handle comprising a movable slider arranged in a longitudinal opening having a first end and a second end; and
an insertion tube attached to the slider, wherein
the slider reversibly locks the intrauterine system in relation to the handle via the removal string;
(c) pushing the slider forward towards the first end of the opening, thereby moving the insertion tube towards the intrauterine system and retracting the intrauterine system into the insertion tube; (d) introducing the inserter into a uterus of the patient with the one hand; and (e) moving the slider towards the second end of the opening, thereby releasing the removal string and intrauterine system within the uterus.

2 . The method of claim 1 , where the inserter further comprises an adjustable flange arranged on the insertion tube.

3 . The method of claim 2 , further comprising:
sounding the uterus to predetermine a depth for placement of the intrauterine system; and adjusting the flange to correspond to the predetermined depth.

4 . The method of claim 1 , wherein the removal string is contained wholly within the insertion tube and handle.

5 . The method of claim 1 , wherein the hormone is levonorgestrel.

6 . The method of claim 2 , wherein the hormone is levonorgestrel.

7 . The method of claim 3 , wherein the hormone is levonorgestrel.

8 . The method of claim 4 , wherein the hormone is levonorgestrel.

9 . A method of positioning an intrauterine system in a patient, comprising:
(a) providing the intrauterine system having a reservoir containing a hormone and a removal string attached to the intrauterine system; (b) holding an inserter in one hand, the inserter comprising:
a handle comprising a movable slider arranged in a longitudinal opening having a first end and a second end; and
an insertion tube attached to the slider, wherein
the slider reversibly locks the intrauterine system in relation to the handle via the removal string;
(c) pushing the slider forward towards the first end of the opening, thereby moving the insertion tube towards the intrauterine system and retracting the intrauterine system into the insertion tube; (d) introducing the inserter into a uterus of the patient with the one hand; and (e) moving the slider towards the second end of the opening, thereby releasing the removal string and intrauterine system within the uterus.

10 . The method of claim 9 , where the inserter further comprises an adjustable flange arranged on the insertion tube.

11 . The method of claim 10 , further comprising:
sounding the uterus to predetermine a depth for placement of the intrauterine system; and adjusting the flange to correspond to the predetermined depth.

12 . The method of claim 9 , wherein the removal string is contained wholly within the insertion tube and handle.

13 . The method of claim 9 , wherein the hormone is levonorgestrel.

14 . The method of claim 10 , wherein the hormone is levonorgestrel.

15 . The method of claim 11 , wherein the hormone is levonorgestrel.

16 . The method of claim 12 , wherein the hormone is levonorgestrel.
