Abstract
Abstract A composition which is injectable from a syringe and a method for using the composition to eliminate wrinkles of the skin. The composition contains sterile cartilage particles, which are non-absorbable by the human body, and which are uniformly dispersed in a liquid. The composition is used by injecting it, with a syringe, directly under the area where the wrinkle occurs.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
A method for eliminating wrinkles in the skin of humans which comprises: injecting, with a syringe, a syringe injectable composition which is substantially non-absorbable by the human body, directly under the area where said wrinkle occurs along substantially its entire length, the amount of said syringe injectable composition injected being substantially sufficient to smooth the skin where the wrinkle exists, said syringe injectable composition consisting essentially of sterile cartilage particles which are substantially non-absorbable by the human body, the size of said sterile, non-absorbable cartilage particles being such that the largest of said particles are smaller than and will flow through the injectable opening of said syringe.
Claim 2
Independent Claim
107 words
A method for eliminating wrinkles in the skin of humans which comprises: injecting, with a syringe, a syringe injectable composition which is substantially non-absorbable by the human body, directly under the area where said wrinkle occurs along substantially its entire length, the amount of said syringe injectable composition injected being substantially sufficient to smooth the skin where the wrinkle exists, said syringe injectable composition consisting essentially of sterile cartilage particles which are substantially non-absorbable by the human body, the size of said sterile, non-absorbable cartilage particles being such that the largest of said particles are smaller than and will flow through the injectable opening of said syringe.
Claim 3
Dependent Claim
39 words
A method according to claim 1 wherein said sterile, non-absorbable cartilage particles are uniformly dispersed throughout a non-toxic liquid, said sterile non-absorbable cartilage particles being present in an amount of between about 80 weight percent and 95 weight percent.
Claim 4
Dependent Claim
15 words
A method according to claim 2 wherein said non-toxic liquid is a non-toxic aqueous liquid.
Claim 5
Dependent Claim
17 words
A method according to claim 3 wherein said non-toxic aqueous liquid is a non-toxic aqueous saline solution.
Claim 6
Dependent Claim
29 words
A method according to claim 4 wherein said non-toxic aqueous saline solution consists essentially of water and from about 0.5 weight percent to about 5 weight percent sodium chloride.
Claim 7
Dependent Claim
17 words
A method according to claim 5 wherein said non-toxic aqueous saline solution is a physiological saline solution.
Claim 8
Dependent Claim
22 words
A method according to claim 1 wherein the largest of said sterile, non-absorbable cartilage particles are less than about 5 Tyler mesh.
Claim 9
Dependent Claim
16 words
A method according to claim 1 wherein said sterile, non-absorbable cartilage particles have never been dry.
