Anatomically conforming vaginal insert
View Patent ↗A vaginal insert formed from a composition that, prior to introduction to the vagina, has the physical properties of a liquid, semi-soft gel, paste, foam, or viscous material so that it can be effectively delivered to the vaginal canal. After introduction into the vagina, the composition will expand and/or solidify into a semi-solid or solid structure to substantially fill the entire “H” shaped space of the vagina and a portion of the rugal folds along the length of the vaginal canal. Upon solidifying, the composition defines an insert that, in one embodiment, is suitable for use as a tampon and, in another embodiment, is suitable for use as an incontinence device.
1. An anatomically conforming vaginal insert formed from a composition wherein the composition includes a material which is introduced into a vaginal canal as a viscous material at a first temperature and after insertion into the vaginal canal becomes a semi-solid at a second temperature greater than the first temperature, wherein the first temperature is about 20° C. and the material has increased solidity at the second temperature as compared to the first temperature.
2. The vaginal insert of claim 1 wherein the composition is selected from the group consisting of a material selected from polyurethane, silicone, a hydrogel, temperature sensitive polymeric materials, ion sensitive materials, bioelastic polypeptide polymers, a multi-component reverse thermo-sensitive polymeric system, and a fibrous absorbent structure resembling an open cell polymeric foam.
3. The vaginal insert of claim 2 wherein the material is a temperature sensitive polymeric material having a low critical solution temperature such that the second temperature is about 37° C.
4. The vaginal insert of claim 1 wherein the insert is hydrophobic.
5. The vaginal insert of claim 4 wherein the vaginal insert is an incontinence insert.
6. The vaginal insert of claim 5 wherein the vaginal insert supports musculature around a bladder neck.
7. The vaginal insert of claim 1 wherein the composition expands upon contact with the vaginal canal.
8. The vaginal insert of claim 7 wherein upon expansion, the insert substantially fills an entire lateral portion of the vaginal canal.
9. The vaginal insert of claim 1 wherein the material is a polymer having lower solubility at the second temperature than the first temperature.
10. The vaginal insert of claim 1 wherein the material is a liquid, semi-soft liquid, gel, paste, foam or other viscous material at a temperature of about 16° to about 27° C., but forms a semi-solid material at a temperature of about 35° to about 39° C.
11. The vaginal insert of claim 1 wherein the insert is non-absorbent.
12. The vaginal insert of claim 11 wherein the material is selected from the group consisting of a material selected from polyurethane, silicone, temperature sensitive polymeric materials, ion sensitive polymeric materials, and humidity activated materials having a shape memory.
13. The vaginal insert of claim 1 wherein the material is adapted to function as a tampon or continence restoration device.
14. The vaginal insert of claim 1 , wherein the vaginal insert is formulated with a withdrawal device, so that when the material solidifies after entering the body, the withdrawal device is secured within the insert as a result of the material solidifying.
15. An anatomically conforming vaginal insert formed from a composition that is introduced into a vaginal canal as a liquid, semi-soft liquid, gel, paste, foam or viscous composition at a temperature of about 16° to about 27° C., and after insertion into the vaginal canal becomes a solid or semi-solid material at a temperature of about 35° to about 39° C., wherein the vaginal insert is formulated with a withdrawal device, so that when the composition solidifies, the withdrawal device is secured within the insert as a result of the composition solidifying.
16. The vaginal insert of claim 15 wherein the composition is adapted for use as a tampon or continence restoration device.
