Abstract
Abstract This biological replacement material for soft tissues utilizes hair clipped in advance of the surgery and properly treated to insure that no biological micro-organisms or other contaminants are on the hair. The harvested hair is cut to an appropriate length, whereupon it may be woven, encapsulated or otherwise combined with a physiologically degradable material to form the hair into an anatomically useful structure.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
69 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in a non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, and chopped into strands of a predetermined length wherein said strands form a non-woven mass suitable for insertion within a biological cavity such that said cavity is filled with said mass.
Claim 2
Dependent Claim
69 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in a non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, and chopped into strands of a predetermined length wherein said strands form a non-woven mass suitable for insertion within a biological cavity such that said cavity is filled with said mass.
Claim 3
Dependent Claim
21 words
A replacement material as defined in claim 1 wherein said hair is confined within a physiologically degradable confinement vehicle for implantation.
Claim 4
Dependent Claim
13 words
A replacement material as defined in claim 1 wherein said hair is autologous.
Claim 5
Dependent Claim
63 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in a non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, cut into suitable lengths and formed into elongated woven strands with said hair lengths oriented substantially along a longitudinal axis of said elongated woven strands.
Claim 6
Dependent Claim
63 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in a non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, cut into suitable lengths and formed into elongated woven strands with said hair lengths oriented substantially along a longitudinal axis of said elongated woven strands.
Claim 7
Dependent Claim
13 words
A replacement material as defined in claim 4 wherein said hair is autologous.
Claim 8
Dependent Claim
83 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in a non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, cut into suitable lengths and formed into elongated woven strands with said hair lengths oriented substantially along a longitudinal axis of said elongated woven strands; and strands of a physiologically degradable material are interwoven with said hair lengths and oriented along said elongated woven strands.
Claim 9
Dependent Claim
83 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in a non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, cut into suitable lengths and formed into elongated woven strands with said hair lengths oriented substantially along a longitudinal axis of said elongated woven strands; and strands of a physiologically degradable material are interwoven with said hair lengths and oriented along said elongated woven strands.
Claim 10
Dependent Claim
13 words
A replacement material as defined in claim 6 wherein said hair is autologous.
Claim 11
Dependent Claim
50 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, and woven into a fabric with said hairs oriented transversely and longitudinally therein.
Claim 12
Dependent Claim
50 words
A biological replacement material for use in soft tissue replacement procedures comprising a predetermined quantity of harvested hair, wherein said hair is sterilized and washed in non-ionic detergent, washed in an isotonic salt to eliminate micro-organism bacteria, and woven into a fabric with said hairs oriented transversely and longitudinally therein.
Claim 13
Dependent Claim
23 words
A replacement material as defined in claim 8 wherein said hair is interwoven with strands of physiologically degradable material to form said fabric.
Claim 14
Dependent Claim
13 words
A replacement material as defined in claim 8 wherein said hair is autologous.
