Abstract

Claims (41)

1. An intravaginal device comprising:

a. at least one fluid transport element comprising:

i. a first plate having an outwardly oriented surface and an inwardly oriented surface;

ii. a second plate coupled to the first plate;

1) that has a first surface disposed and maintained in facing relationship with the inwardly oriented surface of the first plate and an opposite surface; and

2) that is capable of separating from the first plate sufficiently to provide inter-plate capillary action; and

b. a fluid storage element having a longitudinal axis, the fluid storage element being in fluid communication with the at least one fluid transport element;

wherein the at least one fluid transport element is bendable about an axis substantially parallel to the longitudinal axis of the fluid storage element.

2. The device of claim 1 , wherein the at least one fluid transport element is arranged and configured to direct fluid to an interface with the fluid storage element associated with the at least one fluid transport element.

3. The device of claim 2 , wherein the fluid transport element comprises additional sets of plates, each set of plates directing fluid to an associated interface with the fluid storage element.

4. The device of claim 1 , wherein the fluid transport element comprises at least one additional plate that is disposed in facing relationship with the opposite surface of the second plate.

5. The device of claim 1 , wherein a plurality of openings extend through at least one of the first and second plates.

6. The device of claim 5 , wherein the at least one of the first and second plates having a plurality of openings extending therethrough comprises an apertured polymeric film.

7. The device of claim 6 , wherein each of the first and second plates comprises an apertured polymeric film.

8. The device of claim 6 , wherein the apertured polymeric film comprises a resilient three-dimensional web having first and second web surfaces,

a. the first web surface having a multiplicity of apertures therein,

b. each of the apertures being defined by a multiplicity of intersecting elements interconnected to one another substantially in the plane of the first web surface,

c. each of the intersecting elements exhibiting a cross-section comprising a base portion in the plane of the first web surface and a sidewall portion joined to each edge of the base portion,

d. the sidewall portions extending generally in the direction toward the second web surface,

e. the sidewall portions being interconnected to one another intermediate the first and the second web surfaces,

f. the interconnected sidewall portions terminating substantially concurrently with one another in the plane of the second web surface.

9. The device of claim 6 , wherein the apertured polymeric film comprises a reticulated polymeric film.

10. The device of claim 1 , wherein the fluid transport element comprises a plurality of spacer elements that are disposed to separate the surfaces of the first and second plates.

11. The device of claim 1 , wherein the bending axis of the at least one fluid transport element is proximate a junction of the at least one fluid transport element and the fluid storage element.

12. The device of claim 1 , wherein the fluid transport element forms an outer surface of the fluid storage element.

13. The device of claim 1 , wherein the fluid transport element extends into the fluid storage element.

14. The device of claim 1 , wherein the fluid storage element comprises an absorbent structure.

15. A tampon comprising:

a. a plurality of fluid transport elements, each element comprising:

i. a first plate comprising an apertured polymeric formed film and having an outwardly oriented surface and an inwardly oriented surface;

ii. a second plate, spaced apart from the first plate, comprising an apertured polymeric formed film and having a first surface disposed in facing relationship with the inwardly oriented surface of the first plate and an opposite surface; and

b. an absorbent fluid storage element in fluid communication with the fluid transport elements wherein the apertured polymeric formed film comprises a resilient three-dimensional web having first and second web surfaces,

c. the first web surface having a multiplicity of apertures therein,

d. each of the apertures being defined by a multiplicity of intersecting elements interconnected to one another substantially in the plane of the first web surface,

e. each of the intersecting elements exhibiting a cross-section comprising a base portion in the plane of the first web surface and a sidewall portion joined to each edge of the base portion,

f. the sidewall portions extending generally in the direction of the second web surface,

g. the sidewall portions being interconnected to one another intermediate the first and the second web surfaces,

h. the interconnected sidewall portions terminating substantially concurrently with one another in the plane of the second web surface.

16. The tampon of claim 15 , wherein each fluid transport element is arranged and configured to direct fluid to an interface with the fluid storage element which is in fluid communication with said fluid transport element.

17. The tampon of claim 15 , wherein the fluid transport element comprises at least one additional plate that is disposed in facing relationship with the opposite surface of the second plate.

18. The tampon of claim 15 , wherein the fluid transport element extends into the fluid storage element.
