Abstract

Disclosed herein are contraceptive medical devices that include at least a polymeric ring, a porous barrier material and an injection molding guide, where the guide may be symmetrical and/or have one or a plurality of planar surfaces, where the device may optionally administer at least one active agent.

Claims (20)

1 . A contraceptive device comprising:

a polymeric ring, a porous barrier material and an injection molding guide,

both of the injection molding guide and the porous barrier material at least partially embedded within the polymeric ring,

wherein the injection molding guide comprises a plurality of planar surfaces,

wherein the injection molding guide has a corner formed by two planar surfaces intersecting at an angle, and

wherein the injection molding guide has a cross-section with a L-shape, a T-shape, an off-set T-shape, a U-shape, a V-shape, a partial V-shape, or an irregular shape.

2 . The contraceptive device of claim 1 wherein the barrier material is a mesh.

3 . The contraceptive device of claim 1 wherein the barrier material is fibrous.

4 . The contraceptive device of claim 1 wherein the injection molding guide is symmetrical.

5 . The contraceptive device of claim 1 wherein the angle is between a 45 degree angle and a 135 degree angle.

6 . The contraceptive device of claim 1 wherein the injection molding guide is affixed to the porous barrier material.

7 . The contraceptive device of claim 1 wherein the injection molding guide is biodegradable.

8 . The contraceptive device of claim 1 wherein the injection molding guide extends into the porous barrier material.

9 . The contraceptive device of claim 1 wherein the polymeric ring comprises an elastomeric polymer.

10 . The contraceptive device of claim 1 wherein the polymeric ring encircles the porous barrier material.

11 . The contraceptive device of claim 1 further comprising a biologically active agent located within the polymeric ring.

12 . The contraceptive device of claim 1 wherein the angle is about 90 degrees.

13 . The contraceptive device of claim 1 , wherein the injection molding guide has a cross-section with a L-shape, a T-shape, an off-set T-shape, a U-shape, a V-shape, a partial V-shape.

14 . The contraceptive device of claim 1 , wherein the injection molding guide has an L-shaped cross-section.

15 . A kit comprising the contraceptive device of claim 1 , the kit further comprising at least one of a lubricant, a spermicidal gel, a spermicidal film, a contraceptive gel and an applicator.
