Abstract
Abstract A housing for enclosing a power source for operating an implanted artificial organ is provided. The housing has an annular rim defining an aperture and is mounted in the human body such that replacement of the power source through the aperture is effected from outside the body without resort to surgical means. The housing is secured in the body by attachment to internal tissue, preferably bone.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
63 words
The method of mounting a power supply in a human body comprising the steps of: forming a hole in the skin; inserting a cup shaped housing having an annular rim surrounding an aperture such that said rim extends outside the skin; securing said housing to body tissue comprising bone matter at least in part; and removably inserting a power supply into said aperture.
Claim 2
Independent Claim
63 words
The method of mounting a power supply in a human body comprising the steps of: forming a hole in the skin; inserting a cup shaped housing having an annular rim surrounding an aperture such that said rim extends outside the skin; securing said housing to body tissue comprising bone matter at least in part; and removably inserting a power supply into said aperture.
Claim 3
Independent Claim
61 words
The method of mounting a power supply in a human body comprising the steps of: forming a hole in a hip bone; inserting a cup shaped housing having a flange through said hole; fixing said flange to said hip bone, so that said cup is accessible from outside the body; and, removably inserting a power supply in said cup shaped housing.
Claim 4
Independent Claim
61 words
The method of mounting a power supply in a human body comprising the steps of: forming a hole in a hip bone; inserting a cup shaped housing having a flange through said hole; fixing said flange to said hip bone, so that said cup is accessible from outside the body; and, removably inserting a power supply in said cup shaped housing.
Claim 5
Dependent Claim
16 words
The method of claim 2 wherein said flange conforms to the contours of said hip bone.
Claim 6
Dependent Claim
13 words
The method of claim 2 further wherein said cup shaped housing is rigid.
Claim 7
Dependent Claim
125 words
A power supply unit for an artificial internal organ comprising: a cup shaped housing impervious to the flow of internal body fluids having a flange for attachment to body tissue comprising bone material at least in part, said housing having an annular rim extending outwardly from said flange for attachment to the outside of the skin said housing having an interior surface and an exterior surface, said cup shaped housing being adapted to be mounted on a living body with the exterior surface extending into said body and said interior surface accessible from outside said body; conductors passing through said housing and being exposed at said interior surface; and a source of electrical power removably disposed in said housing and electrically connected to said conductors.
Claim 8
Dependent Claim
125 words
A power supply unit for an artificial internal organ comprising: a cup shaped housing impervious to the flow of internal body fluids having a flange for attachment to body tissue comprising bone material at least in part, said housing having an annular rim extending outwardly from said flange for attachment to the outside of the skin said housing having an interior surface and an exterior surface, said cup shaped housing being adapted to be mounted on a living body with the exterior surface extending into said body and said interior surface accessible from outside said body; conductors passing through said housing and being exposed at said interior surface; and a source of electrical power removably disposed in said housing and electrically connected to said conductors.
Claim 9
Dependent Claim
14 words
The power supply unit of claim 5 wherein said cup shaped housing is rigid.
Claim 10
Dependent Claim
41 words
The power supply unit of claim 5 further comprising two said sources of electrical power removably disposed in said housing and connected in parallel to permit a continuous supply of power to said artificial internal organ during replacement of said sources.
Claim 11
Dependent Claim
