Abstract
Abstract A method and apparatus for inserting a soft pliable prosthesis, such as a mammary prosthesis, into a human body through an incision. A prosthesis to be inserted is contained in an open mouthed inner bag of flexible fluid impervious sheet material and in a preferred form of the invention, a second outer open mouthed bag of similar material is sealingly joined to the inner bag at the mouths of the bags by means of a ring member seal. The outer bag carries a charge of fluid. The ring member is provided with a flange which may be seated in an open incision, and upon squeezing of the outer bag, the pressure applied to the fluid in the space between the two bags everts the inner bag through the ring member to carry the prosthesis contained therein to the desired position within the body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
77 words
The method of inserting a prosthesis, such as a soft, pliable mammary prosthesis or the like, into a human body via an incision comprising the steps of holding the mouth of a flexible walled fluid impervious bag containing the prosthesis in registry with an opened incision, and applying fluid pressure to the exterior of the bag to at least partially evert the bag through its mouth and said incision to carry said prosthesis inwardly through said incision.
Claim 2
Independent Claim
77 words
The method of inserting a prosthesis, such as a soft, pliable mammary prosthesis or the like, into a human body via an incision comprising the steps of holding the mouth of a flexible walled fluid impervious bag containing the prosthesis in registry with an opened incision, and applying fluid pressure to the exterior of the bag to at least partially evert the bag through its mouth and said incision to carry said prosthesis inwardly through said incision.
Claim 3
Dependent Claim
59 words
The method defined in claim 1 wherein said bag is enclosed within a second bag of similar material sealingly enjoined around the periphery of its mouth to the mouth of the prosthesis containing bag and having a charge of fluid, and the step of applying fluid pressure consists of manually squeezing said second bag to apply a uniform pressure.
Claim 4
Dependent Claim
130 words
Apparatus for inserting a prosthesis, such as a soft, pliable mammary prosthesis or the like, into a human body via an incision comprising a first open mouthed fluid container, an open mouthed inner bag of flexible fluid impervious material received within said first container, sealing means sealing said bag to said first container around the periphery of the mouth, said bag and said first container defining an enclosed fluid chamber surrounding the exterior of said bag, and a prosthesis located within the interior of said bag and adapted to pass through the mouths of said first container and said bag when a charge of fluid contained in said chamber is compressed to evert said bag through its mouth to carry the prosthesis outwardly through the mouth of said first chamber.
Claim 5
Dependent Claim
130 words
Apparatus for inserting a prosthesis, such as a soft, pliable mammary prosthesis or the like, into a human body via an incision comprising a first open mouthed fluid container, an open mouthed inner bag of flexible fluid impervious material received within said first container, sealing means sealing said bag to said first container around the periphery of the mouth, said bag and said first container defining an enclosed fluid chamber surrounding the exterior of said bag, and a prosthesis located within the interior of said bag and adapted to pass through the mouths of said first container and said bag when a charge of fluid contained in said chamber is compressed to evert said bag through its mouth to carry the prosthesis outwardly through the mouth of said first chamber.
Claim 6
Dependent Claim
30 words
The invention defined in claim 3 wherein said first container is a bag of flexible fluid impervious sheet material having an internal volume greater than that of said inner bag.
Claim 7
Dependent Claim
23 words
The invention defined in claim 3 wherein said sealing means comprises a ring member having a central opening capable of passing said prosthesis.
Claim 8
Dependent Claim
45 words
The invention of claim 5 wherein both of said bags enclose said ring member, said inner bag passing from the outer periphery around one end of said ring member and thence through the opening of said ring member into the interior of said second bag.
Claim 9
Dependent Claim
35 words
The invention defined in claim 5 wherein said ring member includes a spout forming flange extending around the periphery of said opening and projecting from said ring member axially outwardly away from said second bag.
Claim 10
Dependent Claim
25 words
The invention defined in claim 3 in which a charge of fluid of a volume sufficient to evert said bag is contained in said chamber.
