Abstract
Abstract Dynamic implants adapted to be implanted in the interior tissue of a subject such as a human being, animal, or the like, the dynamic implant being capable of changing the condition of the subject while acting through the tissue and having such properties as being capable of gradual absorption by the tissue. An absorbable type of implant can have dispersed therethrough an agent such as an antibiotic agent, a drug, or the like, so that the latter agent is released continuously while the absorbable substance which forms the implant becomes gradually absorbed by the tissue.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
Method of treating a living being over a prolonged period of time with an agent which affects the health of said living being by causing said agent to be slowly released during said period of time within internal tissue of said living being, which comprises implanting in liquid molten condition a depot of a substance which solidifies in the internal tissue of said living being and which is safely absorbable by said living being, said substance solidifying at the temperature of the body of said living being and being molten and liquid at a higher temperature at which it is implanted, the implanting temperature not adversely affecting the living being during the implanting, said substance having distributed therethrough said agent which affects the health of said living being so that as said substance is absorbed by the living being the agent is released within the internal tissue of said living being to act on its health.
Claim 2
Dependent Claim
156 words

Claim 3
Dependent Claim
36 words
In a method as recited in claim 1 and wherein the depot is situated in internal tissue of the subject adjacent an organ for directly affecting the organ with said agent during release of the latter.
Claim 4
Dependent Claim
53 words
In a method as recited in claim 2 and wherein the molten substance containing said agent is initially injected into the tissue along the organ so that upon solidification of the substance the solid becomes located close to and extends along the organ for releasing the agent which will directly affect the organ.
Claim 5
Dependent Claim
22 words
In a method as recited in claim 1 and wherein said substance is a hydrogenated vegetable oil, animal fat, or the like.
Claim 6
Dependent Claim
15 words
In a method as recited in claim 1 and wherein said agent is an antibiotic.
Claim 7
Dependent Claim
15 words
