Treatment device
View Patent ↗A treatment device having a first portion in a first plane, a treatment portion with a cover in a second plane that defines a treatment volume extending between the first and second planes, and a flexible transition portion that connects the first portion to the treatment portion. The treatment portion including a polymeric foam ring having interior and exterior walls extending from the first plane to the second plane. The cover spanning the interior wall thereby forming a closed treatment volume. The polymeric foam ring may be impregnated with a medicament selected from the group including an antibiotic material, an antifungal material, an antimicrobrial material, a deodorant material and nitric oxide. The cover may include a pocket for use with an accessory, such as a heater or mapping grid. A method of treating a treatment area on a patient's skin with the treatment device. The treatment device includes a closed treatment volume having polymeric foam ring impregnated with a medicament. The treatment device is attached to the patient's skin, such that the closed treatment volume encloses the treatment area. The medicament is released into the treatment volume to bring the medicament into contact with the treatment area. Additional steps may include inserting a heater into the pocket or inserting the mapping grid into the pocket and tracking the treatment area with the mapping grid.
1. A treatment device comprising:
an attachment portion in a first plane;
a cover in a second plane for defining a non-contact treatment volume over a treatment area;
a polymeric foam ring extending from the first plane to the second plane;
a flexible transition membrane outside the polymeric foam ring coupling the attachment portion to the cover;
the polymeric foam ring having an interior wall and an exterior wall, each of the walls extending between the first plane and the second plane;
the cover spanning at least the distance of the interior wall to form a closed treatment volume; and
a medicament means in the polymeric foam ring for being released into the treatment volume by the application of heat to the treatment volume.
2. The treatment device of claim 1 wherein the polymeric foam ring is made from polyurethane.
3. The treatment device of claim 1 wherein the polymeric foam ring is made from reticulated polyurethane.
4. The treatment device of claim 1 wherein the attachment portion is a flexible flange.
5. The treatment device of claim 4 wherein the flexible flange includes an adhesive layer.
6. The treatment device of claim 5 wherein the adhesive layer is covered with a release liner.
7. The treatment device of claim 1 further comprising a pocket on the cover.
8. The treatment device of claim 7 further including an active heater in the pocket.
9. The treatment device of claim 7 further including an accessory device in the pocket.
10. The treatment device of claim 9 wherein the accessory device is a passive heater.
11. The treatment device of claim 9 wherein the accessory device is a mapping grid.
12. A method of treating an area on a patient's skin with a treatment device defining a closed treatment volume, the device including a first portion in a first plane, a treatment portion including a medicament impregnated foam ring extending from the first plane to a second plane and a cover in the second plane for defining a treatment volume over the treatment area, and a flexible transition portion for coupling the first portion to the treatment portion, comprising:
attaching the treatment device to the patient's skin, such that the treatment volume encloses the treatment area;
flexing the transition portion to accommodate patient motion;
heating the treatment volume; and
releasing the medicament into the treatment volume in response to heat in the treatment volume.
13. The method of claim 12 , wherein the cover is transparent, further comprising viewing the treatment area through the transparent cover.
14. The method of claim 12 , wherein the cover is a mapping grid, further comprising tracking the treatment area with the mapping grid.
15. The method of claim 12 , wherein the cover is a passive heater with a reflective surface, further comprising heating the treatment volume.
16. The method of claim 12 , wherein the cover includes a pocket, further comprising:
inserting a mapping grid into the pocket; and
tracking the treatment area with the mapping grid.
17. The method of claim 12 , wherein the cover includes a pocket, further comprising:
inserting a heater into the pocket; wherein
heating the treatment volume is performed by operating the heater.
18. The method of claim 12 wherein the medicament is selected from the group consisting of an antibiotic material, an antifungal material, an antimicrobial material, a deodorant material and nitric oxide.
19. A method of tissue treatment using a treatment device defining a treatment volume impregnated with medicament, comprising:
attaching the treatment device over a treatment area, out of contact with the treatment area, such that the treatment volume encloses the treatment area;
flexing a transition membrane of the treatment device to accommodate motion; and
releasing the medicament into the treatment volume by heating the treatment volume.
20. The method of claim 19 , wherein the cover is transparent, further comprising viewing the treatment area through the transparent cover.
21. The method of claim 19 , wherein the cover is a mapping grid, further comprising tracking the treatment area with the mapping grid.
22. The method of claim 19 , wherein the cover is a passive heater with a reflective surface.
23. The method of claim 19 , wherein the treatment device further includes a pocket over the treatment area, further comprising:
inserting a mapping grid into the pocket; and
tracking the treatment area with the mapping grid.
24. The method of claim 19 , wherein the treatment device further includes a pocket over the treatment area, and heating the treatment volume includes:
inserting a heater into the pocket; and
operating the heater.
25. The method of claim 19 wherein the medicament is selected from the group consisting of an antibiotic material, an antifungal material, an antimicrobial material, a deodorant material and nitric oxide.
