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
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 including a material that 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,
1. An anatomically-conforming vaginal insert formed from a composition including a material that 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 material has increased solidity at the second temperature as compared to the first temperature, and wherein the insert is absorbent. 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 insert is a catamenial insert. 8. The vaginal insert of claim 1, wherein the composition expands upon contact with the vaginal canal. 9. The vaginal insert of claim 8, wherein upon expansion, the insert substantially fills an entire lateral portion of the vaginal canal. 10. The vaginal insert of claim 1, wherein the material is a polymer having lower solubility at the second temperature than the first temperature. 11. 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. 12. The vaginal insert of claim 1, wherein the material is a humidity-activated material having a shape memory. 13. 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. 14. 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, and wherein the insert is absorbent. 15. The vaginal insert of claim 14, wherein the composition is adapted for use as a tampon or continence restoration device. 16. The vaginal insert of claim 14, wherein the composition expands upon contact with the vaginal canal. 17. The vaginal insert of claim 14, wherein the composition includes a polymer having lower solubility at the second temperature than the first temperature. 18. The vaginal insert of claim 14, wherein the insert is a catamenial insert. 19. The vaginal insert of claim 14, 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. 20. The vaginal insert of claim 14, wherein the vaginal insert is an incontinence insert configured to support musculature around a bladder neck.
