Abstract

An intravaginal pessary device in an applicator is provided. The device has a top and a bottom, and a sidewall that extends between the top and the bottom. The sidewall, top and bottom form an outer periphery defining a total area of the device. The pessary device has a maximum diameter that is less than about 25 mm. The pessary device and applicator exhibit a maximum expulsion force that is below 1500 grams.

First claim

What is claimed is:

1. An intravaginal pessary device housed within an applicator, wherein the applicator comprises a barrel region with an insertion end, the insertion end comprising a containment element, the containment element comprising at least one petal that holds the pessary device within the barrel region, wherein the pessary device and the applicator are configured such that they exhibit a maximum expulsion force that is greater than 0 and less than 1500 grams-force, and wherein the pessary device and the applicator exhibit an expulsion force profile that has a two peak structure with a first peak occurring proximate commencement of application of expulsion force, a second peak occurring proximate completion of the application of the expulsion force, wherein the first and second peaks are the highest two peaks of the force profile, neither peak exceeds 4 Newtons, the second peak is a percentage of the first peak, and the area between the two peaks drops to below 2 Newtons; wherein the maximum expulsion force is at least in part a force required to open the at least one petal and thereby urge the pessary device through the insertion end of the applicator.

2. The pessary device and applicator of claim 1 , wherein the pessary device has a maximum lateral dimension, wherein the maximum lateral dimension is located closer to a top or bottom of the pessary device than to a mid-section of the pessary device.

3. The pessary device and applicator of claim 1 , wherein the barrel region has an inner lateral dimension and the pessary device has a maximum lateral dimension and the inner lateral dimension of the barrel region is greater than the maximum lateral dimension of the pessary device.

4. The pessary device and applicator of claim 3 , wherein the barrel region is circular in cross section and the inner lateral dimension is an inner diameter of the barrel region.

5. The pessary device and applicator of claim 4 , wherein the pessary device at the maximum lateral dimension is circular in cross section and the maximum lateral dimension is a maximum diameter of the pessary device.

6. The pessary device and applicator of claim 1 , wherein the pessary device has a length between 35 mm and 60 mm and the maximum lateral dimension is greater than 10 mm and less than 35 mm.

7. The pessary device and applicator of claim 1 , wherein the pessary device has a weight greater than 1 gram and less than 10 grams.

8. The pessary device and applicator of claim 1 , wherein the pessary device and the applicator require greater than 0 Newtons per mm and less than 1000 Newtons per mm average to expel the pessary device.

9. The pessary device and applicator of claim 1 , wherein the applicator barrel has an inner diameter greater than 5 mm and less than 22 mm.

10. The pessary device and applicator of claim 1 , wherein the pessary device is in the shape of an hourglass, a waisted cylinder, a figure-8 or a peanut.

11. The pessary device and applicator of claim 1 , wherein the pessary device comprises a convex portion and a concave portion, and wherein the convex portion provides more resistance to expulsion force than the concave portion.
