Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
70 words
An autologous implant prosthesis for insertion into a living being, comprising: a flexible envelope; a volume of mammalian adipose tissue obtained from said living being, said mammalian adipose tissue containing a high percentage of triglycerides, retained within said flexible envelope, said adipose tissue being incapable of vascularized contact with adjacent tissue upon insertion of said adipose-filled envelope into said living being from which the volume of adipose tissue was obtained.
Claim 2
Dependent Claim
70 words
An autologous implant prosthesis for insertion into a living being, comprising: a flexible envelope; a volume of mammalian adipose tissue obtained from said living being, said mammalian adipose tissue containing a high percentage of triglycerides, retained within said flexible envelope, said adipose tissue being incapable of vascularized contact with adjacent tissue upon insertion of said adipose-filled envelope into said living being from which the volume of adipose tissue was obtained.
Claim 3
Dependent Claim
18 words
The implant prosthesis as recited in claim 1 wherein said mammalian adipose tissue comprises fatty acids and glycerol.
Claim 4
Dependent Claim
19 words
The implant prosthesis as recited in claim 1 wherein said implant prosthesis further comprises an antimicrobial within said envelope.
Claim 5
Dependent Claim
27 words
The implant prosthesis as recited in claim 1 wherein said implant prosthesis further comprises one or more components from the group consisting of anticoagulants, buffers, and antioxidants.
Claim 6
Dependent Claim
29 words
The implant prosthesis as recited in claim 1 wherein said flexible envelope comprises one or more materials from the group of materials consisting of silicones, polyurethanes and bio-compatible polymers.
Claim 7
Independent Claim
121 words
A method for producing an autologous implant prosthesis for subsequent insertion into a living being comprising the steps of: (a) obtaining a reservoir of substantially mammalian adipose tissue from a living being, said mammalian adipose tissue containing a high percentage of triglycerides; (b) introducing a determined volume of said adipose tissue from said reservoir into a flexible envelope of suitable material for use as a prosthetic shell; (c) sealing said flexible envelope containing said adipose tissue to create an implant prosthesis, said adipose tissue being incapable of vascularized contact with adjacent tissue upon insertion of said envelope into said human body; and (d) surgically implanting said implant prosthesis into said living being from which the reservoir of adipose tissue was obtained.
Claim 8
Independent Claim
121 words
A method for producing an autologous implant prosthesis for subsequent insertion into a living being comprising the steps of: (a) obtaining a reservoir of substantially mammalian adipose tissue from a living being, said mammalian adipose tissue containing a high percentage of triglycerides; (b) introducing a determined volume of said adipose tissue from said reservoir into a flexible envelope of suitable material for use as a prosthetic shell; (c) sealing said flexible envelope containing said adipose tissue to create an implant prosthesis, said adipose tissue being incapable of vascularized contact with adjacent tissue upon insertion of said envelope into said human body; and (d) surgically implanting said implant prosthesis into said living being from which the reservoir of adipose tissue was obtained.
Claim 9
Dependent Claim
31 words
The method for producing an implant prosthesis as recited in claim 6 comprising the further step of, inserted following step (a) or (b): (e) cleansing said reservoir of said adipose tissue.
Claim 10
Dependent Claim
45 words
The method for producing an implant prosthesis as recited in claim 6 comprising the further step of, inserted following step (a) or (b): (f) adding one or more components from the group consisting of antimicrobials, anticoagulants, buffers, and antioxidants to said reservoir of adipose tissue.
Claim 11
Dependent Claim
21 words
The method for producing an implant prosthesis as recited in claim 6 wherein said adipose tissue comprises fatty acids and glycerol.
Claim 12
Dependent Claim
33 words
The method for producing an implant prosthesis as recited in claim 6 wherein said flexible envelope comprises one or more materials from the group of materials consisting of silicones, polyurethanes and bio-compatible polymers.
Claim 13
Dependent Claim
23 words
The method for producing an implant prosthesis as recited in claim 6 wherein said reservoir has a volume of at least 400 milliliters.
Claim 14
Dependent Claim
19 words
The method for producing an implant prosthesis as recited in claim 6 wherein said adipose tissue is a semi-solid.
Claim 15
Independent Claim
154 words
The method for producing an autologous implant prosthesis for subsequent insertion into a living being comprising the steps of: (a) obtaining a reservoir of substantially mammalian adipose tissue from a living being, said mammalian adipose tissue containing a high percentage of triglycerides; (b) introducing at least a portion of a determined volume of said adipose tissue from said reservoir into a flexible envelope of suitable material for use as a prosthetic shell; (c) surgically implanting said flexible envelope containing at least a portion of said determined volume of said adipose tissue into said living being from which the reservoir of adipose tissue was obtained; (d) introducing a remainder of said determined volume of said adipose tissue into said flexible envelope; (e) sealing said flexible envelope containing said adipose tissue to create an implant prothesis, said adipose tissue being incapable of vascularized contact with adjacent tissue upon insertion of said envelope into said human body.
Claim 16
Independent Claim
154 words
The method for producing an autologous implant prosthesis for subsequent insertion into a living being comprising the steps of: (a) obtaining a reservoir of substantially mammalian adipose tissue from a living being, said mammalian adipose tissue containing a high percentage of triglycerides; (b) introducing at least a portion of a determined volume of said adipose tissue from said reservoir into a flexible envelope of suitable material for use as a prosthetic shell; (c) surgically implanting said flexible envelope containing at least a portion of said determined volume of said adipose tissue into said living being from which the reservoir of adipose tissue was obtained; (d) introducing a remainder of said determined volume of said adipose tissue into said flexible envelope; (e) sealing said flexible envelope containing said adipose tissue to create an implant prothesis, said adipose tissue being incapable of vascularized contact with adjacent tissue upon insertion of said envelope into said human body.
Claim 17
Dependent Claim
31 words
The method for producing an implant prosthesis as recited in claim 13 comprising the further step of, inserted following step (a) or (b): (e) cleansing said reservoir of said adipose tissue.
Claim 18
Dependent Claim
45 words
The method for producing an implant prosthesis as recited in claim 13 comprising the further step of, inserted following step (a) or (b): (f) adding one or more components from the group consisting of antimicrobials, anticoagulants, buffers, and antioxidants to said reservoir of adipose tissue.
Claim 19
Dependent Claim
21 words
