Abstract

An intravaginal device has a working portion (e.g., intravaginal urinary incontinence device suppository, tampon) and an anchoring portion comprising at least one member extending beyond at least one end of the working portion to maintain the working portion in place during use.

Claims

1. An intravaginal urinary incontinence device comprising:

a) a stent comprising an elastic material and having a substantially hollow working portion having a longitudinal axis and first and second generally parallel opposed faces defined by a plurality of at least three longitudinally extending struts, each strut having a length and being substantially parallel to the longitudinal axis to extend in and at least partially define either the first or second generally parallel opposed face and wherein the opposed faces defined by the plurality of longitudinally extending struts are arranged and configured to contact a user'"'"'s vaginal tissue along substantially all of the length of the plurality of longitudinally extending struts, wherein the first and second opposed faces are substantially parallel to the longitudinal axis and wherein the working portion has a diameter measured as a maximum distance between the opposed faces; and

b) an anchoring portion to maintain the stent in place during use, the anchoring portion having a width dimension,

wherein the anchoring portion has at least one member extending beyond at least one end of the working portion capable of engaging vaginal walls such that during use, the width dimension of the anchoring portion is larger than the diameter of the working portion, and a withdrawal element is operatively connected to and extends from the working portion.

2. The device according to claim 1 wherein the working portion comprises a slotted tube.

3. The device according to claim 1 wherein the working portion comprises a wire form.

4. The device according to claim 3 wherein the working portion comprises a sinusoidal wire form.

5. The device according to claim 1 wherein the elastic material is a shape memory polymer.

6. The device according to claim 1 wherein the elastic material is a metal alloy.

7. The device according to claim 6 wherein the metal alloy is a nickel-titanium alloy.

8. The device according to claim 1 wherein the anchoring portion is arranged and configured to expand widthwise to engage lateral walls of the vagina.

9. The device according to claim 1 wherein the anchoring portion comprises at least two extensions beyond the at least one end of the working portion.

10. The device according to claim 1 wherein the anchoring portion comprises a basket handle shape.

11. The device according to claim 1 wherein the anchoring portion comprises a dog bone shape.

12. The device according to claim 1 wherein the anchoring portion comprises a rabbit ear shape.

13. The device according to claim 1 wherein the working portion comprises a metallic material.

14. The device according to claim 1 wherein the working portion comprises a shape memory polymer.

15. The device according to claim 3 wherein the wire form comprises a plurality of struts that at least partially extend in and define and support the opposed faces of the working portion.

16. The device according to claim 1 wherein the opposed faces are arranged and configured to contact the user'"'"'s vaginal tissue through an enclosure.

17. The device according to claim 16 wherein the enclosure is a bag.
