Adjustable pessary device and method
View Patent ↗Various embodiments of an adjustable pessary device are provided. The device can include an elastic ribbon or band, such as Nitinol, encapsulated in a soft or flexible structure, such as a rubber shell. In addition to providing a conforming, comfortable shape, the rubber layer can have additional structures to interface and fit with the anatomical structures within the vagina.
1. A conformable medical device for treating incontinence, comprising:
a flexible outer housing; and
an inner band including two elastic undulating ribbon members disposed within the flexible outer housing, the two elastic undulating ribbon members having substantially the same shape and operably connected at first and second end portions, the first end portion having a first tip portion angling away from the two elastic undulating ribbon members in a first direction, the second end portion having a second tip portion angling away from the two elastic undulating ribbon member in a second direction, the second direction being different from the first direction, the device being insertable within a patient's vagina to treat incontinence.
2. The device of claim 1 , wherein the outer housing includes a lumen to receive the inner band.
3. The device of claim 1 , wherein the outer housing is constructed of a rubber material.
4. The device of claim 1 , wherein at least one of the two elastic undulating ribbon members is twisted along its axis.
5. The device of claim 1 , wherein at least one of the two elastic undulating ribbon members are twisted at least one full turn along their length.
6. The device of claim 1 , wherein the inner band is constructed of a polymer material.
7. The device of claim 1 , wherein the inner band is constructed of a Nitinol material.
8. The device of claim 1 , wherein the inner band is constructed of a stainless steel material.
9. The device of claim 1 , wherein the inner band is generally S-shaped.
10. The device of claim 1 , wherein the second direction is opposite to the first direction.
11. An adjustable pessary device to treat incontinence, comprising:
a flexible outer housing including a first undulating member and a second undulating member; and
an inner band including first and second undulating ribbon members, the first undulating ribbon member disposed within the first undulating member of the outer housing and the second undulating ribbon member disposed within the second undulating member of the outer housing, such that the first and second undulating ribbon members are operably joined at first and second end portions, the first and second end portions having tip portions angling away from the first and second undulating ribbon members in opposite directions, for insertion within a patient's vagina to treat incontinence.
12. The device of claim 11 , wherein the outer housing is constructed of a rubber material.
13. The device of claim 11 , wherein the first and second undulating ribbon members are constructed of a shape-memory material.
14. The device of claim 11 , wherein the first and second undulating ribbon members are twisted at least one full turn along their respective lengths.
15. The device of claim 14 , wherein the first and second undulating ribbon members each twist in opposing directions.
16. The device of claim 11 , wherein the inner band is constructed of a polymer material.
17. The device of claim 11 , wherein the inner band is constructed of a Nitinol material.
18. The device of claim 11 , wherein the inner band is constructed of a stainless steel material.
19. The device of claim 11 , wherein at least one of the first and second undulating ribbon members is generally S-shaped.
20. The device of claim 11 , wherein the outer housing is at least in part generally S-shaped.
