Abstract
Abstract An artificial organ or part thereof for implantation into the human body is synthesized from a mixture of albumen and human blood of a selected blood group corresponding to the blood group of the acceptor body, the mixture being plastified and molded into a desired shape, and after hardening and drying constitutes a ready-to-use artificial organ or part thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
In a method of producing artificial organs and parts, sections and the like of artificial organs, adapted to be implanted into a human body, comprising plasticizing a mixture for making the artificial organ into a mass, forming the mass into the shape of the desired artificial organ, and hardening and drying the product resulting from the forming wherein the improvement comprises preparing a mixture of one of artificial albumen, and protein, and human blood of a blood group corresponding to the blood group of a person into the body of whom an artificial organ is to be implanted so as to provide such organ with an immunizing protection.
Claim 2
Dependent Claim
108 words
In a method of producing artificial organs and parts, sections and the like of artificial organs, adapted to be implanted into a human body, comprising plasticizing a mixture for making the artificial organ into a mass, forming the mass into the shape of the desired artificial organ, and hardening and drying the product resulting from the forming wherein the improvement comprises preparing a mixture of one of artificial albumen, and protein, and human blood of a blood group corresponding to the blood group of a person into the body of whom an artificial organ is to be implanted so as to provide such organ with an immunizing protection.
Claim 3
Dependent Claim
60 words
The improvement according to claim 1, wherein said step of plasticizing a mixture comprises employing from 10 to 80 percent of one of albumen and protein and from 80 to 10 percent of the human blood of a blood group corresponding to the blood group of a person into the body of whom the artificial organ is to be implanted.
Claim 4
Dependent Claim
25 words
A method as defined in claim 1, wherein the hardener employed is an aqueous formaldehyde solution having a concentration of from 2 to 20 percent.
Claim 5
Dependent Claim
38 words
The improvement according to claim 1, wherein said step of forming the mass into the shape of the desired artificial organ comprises coating the artificial organ made of suitable material with the mixture after the step of plasticizing.
Claim 6
Dependent Claim
66 words
An artificial organ and parts, sections and the like of artificial organs, adapted to be implanted into a human body comprising a hardened plastomer, said plastomer comprising 10 to 80 percent of one of artificial albumen and protein and 80 to 10 percent human blood of a blood group corresponding to the blood group of the patient in which the artificial organ is to be implanted.
Claim 7
Dependent Claim
66 words
An artificial organ and parts, sections and the like of artificial organs, adapted to be implanted into a human body comprising a hardened plastomer, said plastomer comprising 10 to 80 percent of one of artificial albumen and protein and 80 to 10 percent human blood of a blood group corresponding to the blood group of the patient in which the artificial organ is to be implanted.
Claim 8
Dependent Claim
29 words
The artificial organ according to claim 5, further comprising an inner portion made of suitable material, said plastomer coating and surrounding said inner portion to form said artificial organ.
