Abstract
Abstract A method and apparatus according to which a living being can be provided with an implant which is absorbed into the body. According to the method the implant is situated in the body adjacent the outer skin. The implant is injected in a liquid, molten condition, but assumes a solid condition at body temperature. The composition of the implant is such that the implant will be absorbed by the body at a greater rate when the temperature of the implant is increased. By situating the implant adjacent the outer skin it is possible to elevate the temperature at the outer skin so as to increase the rapidity with which the implant is absorbed by the body. A syringe which contains the implant in solid condition is provided with a heating structure which is operated for the purpose of converting the composition into a liquid molten condition in preparation for injecting the composition into body tissue.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
215 words
Method of treating a living being, with a solid composition which affects the health or appearance of said living being, which comprises implanting in a molten injectable condition in the internal tissue of the living being, sufficiently close to the outer skin of the living being to be influenced by an elevation of temperature of the outer skin, a depot of at least one composition which is safely absorbable by the living being and which solidifies at the temperature of the body of the living being while being molten and injectable at a higher temperature at which it is implanted, the implanting temperature not adversely affecting the living being during the implanting, and said solid composition responding to an increase in temperature at the outer skin of the living being adjacent the location of the solid composition to assume a condition according to which said solid composition is absorbed more rapidly by the body of the living being than if the temperature at the outer skin adjacent the solid composition is not elevated, and thereafter whenever it is desired to increase the rapidity with which the solid composition is absorbed by the body applying heat to the outer skin adjacent the solid composition for reducing the time that the latter remains unabsorbed by the body.
Claim 2
Dependent Claim
215 words
Method of treating a living being, with a solid composition which affects the health or appearance of said living being, which comprises implanting in a molten injectable condition in the internal tissue of the living being, sufficiently close to the outer skin of the living being to be influenced by an elevation of temperature of the outer skin, a depot of at least one composition which is safely absorbable by the living being and which solidifies at the temperature of the body of the living being while being molten and injectable at a higher temperature at which it is implanted, the implanting temperature not adversely affecting the living being during the implanting, and said solid composition responding to an increase in temperature at the outer skin of the living being adjacent the location of the solid composition to assume a condition according to which said solid composition is absorbed more rapidly by the body of the living being than if the temperature at the outer skin adjacent the solid composition is not elevated, and thereafter whenever it is desired to increase the rapidity with which the solid composition is absorbed by the body applying heat to the outer skin adjacent the solid composition for reducing the time that the latter remains unabsorbed by the body.
Claim 3
Dependent Claim
34 words
A method as recited in claim 1 and wherein a heating pad is applied to the outer skin adjacent the solid composition for reducing the time that the latter remains unabsorbed by the body.
Claim 4
Dependent Claim
27 words
A method as recited in claim 1 and wherein said composition is implanted for cosmetic purposes sufficiently close to the outer skin to change the configuration thereof.
Claim 5
Dependent Claim
16 words
A method as recited in claim 3 and wherein said composition is a hydrogenated vegetable oil.
Claim 6
Dependent Claim
33 words
A method as recited in claim 1 and wherein said composition is implanted for affecting the health of the living being and includes an agent such as a drug, medicament, anesthetic, or nutrient.
Claim 7
Dependent Claim
81 words
A method as recited in claim 5 and wherein the agent is in a carrier which is solid at the temperature of the body of the living being while being molten and injectable at the higher temperature at which the composition is implanted, so that the rapidity with which the carrier of the composition is absorbed can be increased by applying heat to the outer skin adjacent the implant in order to increase the dispersal of the agent into the body.
Claim 8
Dependent Claim
18 words
The method of claim 1 and wherein a plurality of said compositions are injected in a single operation.
