Therapeutic agent delivery tampon
View Patent ↗A tampon adapted to deliver a therapeutic agent includes a body having a proximal end and a distal end. The body includes an absorbency zone adjacent the distal end, wherein the absorbency zone includes absorbent material; an application zone adjacent the proximal end and spaced apart from the distal end; and a therapeutic agent positioned substantially within the application zone. A method produces a device for delivering a therapeutic agent. The method includes manufacturing a tampon having a body with a distal end, a proximal end, an absorbency zone adjacent the distal end, and an application zone adjacent the proximal end; and locating a therapeutic agent substantially within the application zone.
1. An absorbent device adapted to deliver a therapeutic agent to a user having a vaginal epithelium, the device comprising:
a generally cylindrical body having a proximal end and a distal end and adapted to be positioned entirely within the user, the body including
an absorbency zone adjacent the distal end, wherein the absorbency zone includes absorbent material;
an application zone adjacent the proximal end and spaced apart from the distal end, wherein the application zone has a surface adapted to contact the vaginal epithelium; and
a formulation including a therapeutic agent positioned substantially adjacent the surface and substantially within the application zone, wherein the formulation including a therapeutic agent includes a hydrogel material or a foam component.
2. The device of claim 1 , wherein the device is a catamenial device.
3. The device of claim 1 , wherein the device is an incontinence device.
4. The device of claim 1 , wherein the device is a tampon.
5. The device of claim 1 , wherein the application zone includes absorbent material.
6. The device of claim 1 , wherein the application zone includes non-absorbent material.
7. The device of claim 1 , further comprising a reservoir within the application zone, wherein the formulation including the therapeutic agent is located substantially within the reservoir.
8. The device of claim 7 , wherein the reservoir is in communication with the application zone surface.
9. The device of claim 7 , wherein the reservoir is located under the application zone surface.
10. The device of claim 1 , wherein the formulation including a therapeutic agent is encapsulated.
11. The device of claim 1 , wherein the body is compressed, and wherein the formulation including a therapeutic agent is applied to the body after the body is compressed.
12. The device of claim 1 , wherein the body is constructed from a material; and wherein the formulation including a therapeutic agent is applied to the material before the body is constructed.
13. A method for producing a device for delivering a therapeutic agent to a user having a vaginal epithelium, the method comprising:
manufacturing a tampon having a generally cylindrical body with a distal end, a proximal end, a longitudinal axis, an absorbency zone adjacent the distal end, and an application zone adjacent the proximal end, wherein the body is adapted to be positioned entirely within the user, wherein the absorbency zone has an absorbency zone surface adapted to contact the vaginal epithelium and absorbent material extending from the longitudinal axis to the absorbency zone surface, wherein the application zone has an application zone surface, and wherein the manufacturing act includes manufacturing the body from a material; and
locating a formulation including a therapeutic agent substantially adjacent the application zone surface and substantially within the application zone, including applying the formulation including a therapeutic agent to the material before the body is manufactured.
14. The method of claim 13 , further comprising providing a tampon applicator such that pressure from the tampon applicator on the body releases the therapeutic agent from the application zone.
