Abstract

To provide a univeral breast prosthesis usable as a substitute for either the right or left breast and for patients who have had varying degrees of surgery, scarring, muscle removal and the like, a breast prosthesis is provided having an upper flap and symmetrical lateral flaps. The upper flap is designed to cover subclavicular defects of varying degrees and can be trimmed as desired depending on the nature and extent of the defect to be covered. Similarly, the opposite lateral flaps are designed to cover sternum and underarm defects, and each can be separately trimmed depending upon the nature and extent of the respective defects.

Claims

1. An external breast prosthesis primarily for mastectomy patients comprising a thin flexible shell of an elastomeric material contoured to conform to the configuration of the breast of the patient and having a peripheral edge extending around the entire periphery of said shell for attachment by an adhesive to the chest wall of the patient and a filler retained within the confines of said thin shell having soft flexible physical characteristics, said shell having a rear portion that is concave within the confines of said peripheral edge so that the prosthesis can be attached at said peripheral edge to the chest wall of a patient to provide within the peripheral edge a chamber of air over the surgical area of the surgical area of the mastectomy, said peripheral edge including an inferior flap, a lateral flap, a superior flap and a medial flap, said inferior, lateral and superior flaps extending in directions away from said concave rear portion and said medial flap extending inward toward said concave rear portion.

2. The external breast prosthesis that is defined in claim 1, wherein said peripheral edge includes an inferior flap, a lateral flap, a superior flap and a medial flap, said inferior, lateral and superior flaps extending in directions away from said concave rear portion and said medial flap extending inward toward said concave rear portion.

3. The external breast prosthesis that is defined in claim 1 wherein said inferior flap extends at least 2 inches away from said concave rear portion, said lateral flap extends at least 6 inches away from said concave rear portion, and said superior flap extends at least 8 inches away from said concave rear portion.

4. The external breast prosthesis that is defined in claim 1 which includes a flexible sheet material bonded to said flaps and forming a part of said peripheral edge, said flexible sheet material defining said concave portion.

5. The external breast prosthesis that is defined in claim 4 wherein said filler is glycerin.

6. The external breast prosthesis that is defined in claim 5 wherein a silicone bag containing air is located in said filler.

7. The external breast prosthesis that is defined in claim 1 wherein said filler is a silicone.

8. The external breast prosthesis that is defined in claim 1 wherein filler is a gel material.

9. The external breast prosthesis that is defined in claim 1 wherein an adhesive that is non-toxic and hypoallergenic is provided for attaching said peripheral edge to the chest wall of the patient.

10. An external breast prosthesis for mastectomy patients comprising a thin flexible shell of an elastomeric material contoured to conform to the configuration of the breast of the patient and having a peripheral edge extending around the entire periphery of the shell, a thin flexible backing member secured to the peripheral edge of said shell and providing a concave rear portion within the confines of the peripheral edge, said shell and said backing member being dimensioned to form an inferior flap, a lateral flap and a superior flap extending away from said concave rear portion, and a medial flap extending inward toward said concave rear portion, said flaps being adapted to be attached by an adhesive to the chest wall of the patient and the concave rear portion being dimensioned so that when the flaps are attached the concave rear portion will define an air chamber over the surgical area of the mastectomy, said shell and said concave rear portion defining an anterior chamber, and a fluid material confined within said anterior chamber.

11. The external breast prosthesis that is defined in claim 10 wherein said shell and said backing are a silicone elastomer and each has a thickness of about 1 millimeter.

12. The external breast prosthesis that is defined in claim 11 wherein said backing member has embedded therein a reinforcing fabric.

13. The external breast prosthesis that is defined in claim 10 wherein said fluid material is glycerin.

14. The external breast prosthesis that is defined in claim 13 wherein said anterior chamber contains a silicone elastomer bag filled with a gas, said bag floating in said glycerin.

15. An external breast prosthesis primarily for mastectomy patients comprising:

a thin flexible fluid impervious shell of elastomeric material defined by a convex front section configured in the shape of a female breast and a concave rear section, said front and rear sections joining each other along a generally circular periphery to define a fluid-tight sealed cavity, said concave rear section defining an air chamber when placed over a wearer'"'"'s chest wall in the region of a removed breast to reduce chaffing promote air circulation and provide an air cushion between the underlying chest wall and said prosthesis in the region of said removed breast,

a liquid contained within said cavity having a density approximately that of a natural breast,

an upper flap extending upwardly from said periphery of said shell, said flap configured to cover subclavicular defects resulting from a mastectomy when said concave rear section is disposed over a wearer'"'"'s chest in the region of a removed breast,

first and second lateral flaps extending laterally from said shell periphery in opposite directions symmetrically relative to said upper flap to facilitate use of said prosthesis as a substitute for both left and right breasts,

said first and second flaps configured to respectively cover lateral and sternum defects resulting from a mastectomy when said concave rear section is disposed over a wearer'"'"'s chest in the region of a removed breast,

each of said flaps being removable in whole and/or in part for tailoring the coverage provided by said flaps to the subclavicular, sternum and lateral defects of the wearer without destroying the fluid-tight chamber of said sealed cavity and the air circulation, antichaffing and cushioning action provided by said air chamber.

16. The prosthesis of claim 15 further including a lower flap extending downwardly from said shell periphery a distance sufficient to become sandwiched between said chest wall and the lower edge of a bra cup containing said liquid-filled shell for inhibiting said prosthesis from riding up on the wearer'"'"'s chest.

17. The prosthesis of claim 15 wherein said flaps are fabricated of silicone, and have their rear exterior surfaces covered with acrylic to promote adhesion of said prosthesis to the chest wall of a wearer with double-sided nonsilicone adhesive tape.

18. The breast prosthesis of claim 15 wherein said rear concave section has a depth of approximately 1 cm at its center.

19. The breast prosthesis of claim 15 wherein said convex section is fabricated of silicone and has a first protuberance to simulate a nipple, said prosthesis further incluidng a thin convex silicone overlay sheet having a curvature approximating that of said convex front section in the region of said first protuberance and having a size corresponding to that of a normal areola, said overlay sheet having a hollow second protuberance in the central portion thereof which is larger than said first protuberance, said overlay intimately contacting said front convex section, to which is coheres without adhesive, only in a small annular region surrounding said first protuberance corresponding to the areola of a nipple, with said hollow second protuberance overlying said first protuberance to provide said convex section with an enlarged nipple.

20. The prosthesis of claim 19 wherein said overlay is air pervious in the region of said hollow second protuberance to permit it to collapse when a force is applied thereto and return to its normal shape when said force is removed.

21. The breast prosthesis of claim 15 wherein said convex front section is fabricated of silicone, said prosthesis further including a thin convex generally circular silicone overlay sheet having a diameter approximating that of a normal areola and a curvature approximating that of said convex front section in the region corresponding to the location of a normal areola, said overlay having a protuberance in the central portion thereof, said overlay intimately contacting said front convex section, to which it coheres without adhesive, in the region of a normal nipple and areola.

22. The prosthesis of claim 21 wherein said protuberance is hollow and air pervious to permit it to collapse when a force is applied thereto and return to its normal shape when said force is removed.

23. The prosthesis of claim 21 wherein said overlay has a thickness in the approximate range of 1-5 mils.

24. A breast prosthesis of claim 16 wherein said front convex section has a thickness in the approximate range of 1-5 mils, allowing it to produce an acute angle with said lower flap, simulating the sag of a normal breast.
