Abstract

Articles of apparel for an amputee'"'"'s residuum and for non-amputees who desire or require padding or joint support.

Claims

1. An open-ended sleeve for use by an amputee or non-amputee, said open-ended sleeve being made of stretchable fabric and adapted to extend from a position above a knee of a wearer to a position below the knee of a wearer, said fabric being predominately stretchable in a circumferential direction above, below,.and behind the knee of a wearer and predominately stretchable in a longitudinal direction in the area of the knee of a wearer.

2. An open-ended sleeve for use by an amputee or non-amputee, said open-ended sleeve being made of elastic fabric, said sleeve being adapted to extend above and below a knee of a wearer, said sleeve comprising a front portion adapted to cover the knee of a wearer and a back portion, the front portion comprising a thicker, higher wear resistant elastic fabric and the back portion comprising a thinner, highly elastic fabric.

3. An open-ended sleeve according to claim 2, wherein the front portion of the sleeve is substantially centered with respect to the knee of a wearer and extends circumferentially around the sleeve for a distance of from about 10% to about 90% of the total circumference of the sleeve.

4. An open-ended sleeve for use by an amputee or non-amputee, said open-ended sleeve being made of fabric coated on one side thereof with polymeric material, wherein said polymeric material comprises at least one styrene isobutylene styrene block copolymer or star-branched, tapered block copolymer.

5. An open-ended sleeve according to claim 4, wherein said polymeric material also comprises mineral oil.

6. An open-ended elastomeric sleeve for use by an amputee or non-amputee, said open-ended sleeve comprising a first open end, a second open end, and an intermediate portion provided between said first open end and second open end, said sleeve further comprising fabric which coats the outside of the first open end, the second open end, and the intermediate portion, and the inside of the intermediate portion only, and said intermediate portion has some means for attaching to a prosthetic socket.

7. The sleeve as claimed in claim 6, wherein some or all of said fabric is fiber-on-end fabric.

8. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering comprising one or more high-stretch portions, and one or more no-stretch or low-stretch portions, said covering being coated on the inside thereof with a foamed or a non-foamed polymeric material.

9. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering comprising two or more portions connected with a type 607 stitch, said covering being coated on the inside thereof with a foamed or a non-foamed polymeric material.

10. The covering of claim 9, wherein said type 607 stitch is a butt seam, lap seam, or tape seam.

11. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering having a docking means for suspension of the covering to the wearer, and said covering being coated on the inside thereof with polymeric material, wherein said polymeric material comprises at least one styrene isobutylene styrene block copolymer.

12. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering being coated on the inside thereof with polymeric material, wherein said polymeric material comprises at least one styrene isobutylene styrene block copolymer.

13. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering being coated on the inside thereof with polymeric material, wherein said polymeric material comprises at least one of Kraton RP6917, RP6924, RP6933, RP6935, RP6936, and MD6933 and Septon 4044 and 4077.

14. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering being coated on the inside thereof with polymeric material, wherein said polymeric material comprises at least one star-branched, tapered block copolymer.

15. A tube sock-shaped covering for enclosing an amputation stump, said covering having an open end for introduction of said stump and a closed end opposite said open end, said covering being coated on the inside thereof with polymeric material, wherein said polymeric material comprises at least one silicone-based thermoplastic vulcanizate.

16. A gel composition comprising at least one styrene isobutylene styrene block copolymer and mineral oil.

17. The gel composition of claim 16 bonded to fabric.

18. A gel composition comprising at least one block copolymer, mineral oil, and at least one of the following antimicrobial agents:

Quaternary Ammonium Compound, Triclosan, and silver ions.

19. The gel composition of claim 18, wherein said Quaternary Ammonium Compound is Benzalkonium Chloride.

20. The gel composition of claim 18 bonded to fabric.
