Abstract

Various embodiments 210, 310, 410, 510, 610 and 710 of a cervical ring are retained on the cervix 12 for delivering a medication into the vagina surrounding the cervix 12 of human female. Each embodiment includes an annular cervical ring of a first material 214, 314, 414, 514, 614 and 714 and a medication 216, 316, 416, 516, 616 and 716 retained by the first material for treating the body. The medication may have a timed release into the vagina.

Claims

1. A method for delivering medication around the exterior of the cervix comprising the steps of;

combining a medication with a cervical ring,

placing the cervical ring around the cervix in the vagina of a woman,

releasing the medication from the ring into the vagina while the ring is retained on the cervix, and

removing the ring from the cervix.

2. A method as set forth in claim 1 wherein the ring is removed from the vagina by dissolving.

3. A method as set forth in claim 1 wherein the ring is mechanically removed from the vagina.

4. A method as set forth in claim 3 including attaching a tether to the ring and pulling the tether to remove the ring from the vagina.

5. A method as set forth in claim 1 including combining first and second different medications with the ring.

6. A method as set forth in claim 5 wherein the ring is removed from the vagina by dissolving.

7. A method as set forth in claim 6 including dissolving that portion of the ring combined with the first medication at a different rate than the portion of the ring combined with the second medication.

8. A method as set forth in claim 1 further defined as combining a wax emulsion and the medication to define the ring and dissolving the ring to remove the ring from the cervix.

9. A method as set forth in claim 1 wherein the medication combined with the ring includes at least one of:

an anti-fungal, an antibiotic, estrogen, progesterone, hormones to improve ovulation, hormones to inhibit ovulation and hormones or medications to promote or inhibit labor.

10. A method as set forth in claim 1 wherein the medication is released from the ring over a predetermined time period for a continuing treatment.

11. A method as set forth in claim 1 including forming the ring with an annular interior frictional surface for frictionally engaging the cervix to retain the ring on the cervix.

12. A method as set forth in claim 1 including forming the ring with an annular interior surface with projections for engaging the cervix to retain the ring on the cervix.

13. A method as set forth in claim 1 including forming the ring with an annular interior surface with a recess for creating a suction engagement with the cervix to retain the ring on the cervix.

14. A method as set forth in claim 1 including forming the ring with an elastically expandable annular interior surface for gripping engagement with the cervix to retain the ring on the cervix.

15. A method as set forth in claim 14 further defined as forming the ring with an annular coiled spring.

16. A method as set forth in claim 14 further defined as forming the ring with an elastic band.

17. A cervical ring for delivering medication around the exterior of the cervix comprising;

an annular cervical ring of a first material,

a medication retained by said first material for treating the body,

said first material including a structural feature for releasing said medication from said ring into the vagina while said ring is retained on the cervix.

18. A cervical ring for delivering medication around the exterior of the cervix comprising;

an annular cervical ring of a first material,

a medication retained by said first material for treating the body,

said ring including a retainer for retaining said ring on the cervix and of said first material for releasing said medication from said ring into the vagina while said ring is retained on the vagina.

19. A ring as set forth in claim 18 wherein said first material is dissolvable in the vagina for removing said ring from the vagina by dissolving.

20. A ring as set forth in claim 18 including a tether attached to said ring for pulling said tether to remove said ring from the vagina.

21. A ring as set forth in claim 18 wherein said ring includes first and second different medications.

22. A ring as set forth in claim 21 wherein said first material is dissolvable in the vagina for removing said ring from the vagina by dissolving.

23. A ring as set forth in claim 22 wherein that portion of said ring combined with said first medication is dissolvable at a different rate than the portion of said ring combined with said second medication.

24. A ring as set forth in claim 18 wherein said ring includes a combination of a wax emulsion and said medication for dissolving said ring to remove said ring from the cervix.

25. A ring as set forth in claim 18 wherein said medication combined with said ring includes at least one of:

an anti-fungal, an antibiotic, estrogen, progesterone, hormones to improve ovulation, hormones to inhibit ovulation and hormones or medications to promote or inhibit labor.

26. A ring as set forth in claim 18 wherein said medication includes a predetermined release rate for release from said ring over a predetermined time period for a continuing treatment.

27. A ring as set forth in claim 18 wherein said ring includes an annular interior frictional surface for frictionally engaging the cervix to retain said ring on the cervix.

28. A ring as set forth in claim 18 wherein said ring includes an annular interior surface with projections for engaging the cervix to retain said ring on the cervix.

29. A ring as set forth in claim 18 wherein said ring includes an annular interior surface with a recess for creating a suction engagement with the cervix to retain said ring on the cervix.

30. A ring as set forth in claim 18 wherein said ring includes an elastically expandable annular interior surface for gripping engagement with the cervix to retain said ring on the cervix.

31. A ring as set forth in claim 30 wherein said elastically expandable annular interior surface includes an annular coiled spring.

32. A ring as set forth in claim 30 wherein said elastically expandable annular interior surface includes an elastic band.
