Abstract
Abstract A method for effecting in vitro/in vivo fertilization in which an oocyte and its follicle are removed from the mother. In a host mother, the wall which separates the intraperitoneal fluid from the extraperitoneal fluid is perforated, and placed within this perforation is a culture container. Introduced into this container are the oocyte and its follicular fluid, the spermatozoa and a culture medium. After fertilization and multiplication of the cells under optional artificial conditions, the transfer of the embryo and the nidation are carried out in a substantially normal manner.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
98 words
A device for carrying out in-vitro/in-vivo fertilization in a procedure in which a passage is perforated through the uterine wall in a host mother, said device comprising a balloon-like culture container for receiving an oocyte and its follicular liquid removed from a mother, spermatozoa and a culture medium, and a relatively rigid neck attached to said container and communicating therewith, said neck being insertable in said passage and having a length substantially equal to the thickness of the wall, said neck being provided on its outside with means serving to resist sliding of the neck along said passage.
Claim 2
Independent Claim
98 words
A device for carrying out in-vitro/in-vivo fertilization in a procedure in which a passage is perforated through the uterine wall in a host mother, said device comprising a balloon-like culture container for receiving an oocyte and its follicular liquid removed from a mother, spermatozoa and a culture medium, and a relatively rigid neck attached to said container and communicating therewith, said neck being insertable in said passage and having a length substantially equal to the thickness of the wall, said neck being provided on its outside with means serving to resist sliding of the neck along said passage.
Claim 3
Dependent Claim
25 words
A device as set forth in claim 1, characterized by the fact that the wall of the balloon-like container is formed of a flexible material.
Claim 4
Dependent Claim
26 words
A device as set forth in claim 2, characterized by the fact that the constituent materials of the neck and the balloon like container are elastic.
Claim 5
Dependent Claim
28 words
A device as set forth in claim 3, characterized by the fact that the end of the neck facing away from the balloon is shaped as a collar.
Claim 6
Dependent Claim
19 words
A device as set forth in claim 4, characterized by the fact that said collar is formed by sectors.
Claim 7
Dependent Claim
19 words
A device as set forth in claim 5, characterized by the fact that each sector has a folding groove.
Claim 8
Dependent Claim
34 words
A device as set forth in claim 6, characterized by the fact that the shape of the neck is that of two coaxial barrel-like segments, the junction of the segments forming an intaglio relief.
Claim 9
Dependent Claim
44 words
A device as set forth in claim 7, characterized by the fact that the constituent material of the neck is a silicone elastomer of maximum hardness while the constituent material of the balloon is a silicone elastomer of rather low hardness but great elasticity.
Claim 10
Dependent Claim
40 words
A device as set forth in claim 1, characterized by the fact that a guide strand is attached within the neck in such a manner that the attachment can be broken by means of twisting movements exerted on the strand.
Claim 11
Dependent Claim
28 words
A device as set forth in claim 1, characterized by the fact that the lower end of the neck is provided with a membrane acting as a flap.
Claim 12
Dependent Claim
121 words
An "in-vitro/in-vivo" fertilization method comprising the steps of: A removing from a mother an oocyte and the liquid in its follicle; B perforating the uterine wall separating intraperitoneal fluid from extraperitoneal fluid in a host mother to form a passage through the wall; C placing a culture container having a neck attached thereto and communicating therewith so that the neck extends into the passage through said wall; and D introducing the oocyte and its follicular liquid, spermatozoa and a culture medium into said container whereby after fertilization and multiplication of the cells in the container under optimal artificial conditions, the transfer of the embryo from the container through the neck and its nidation can be effected in a substantially natural manner.
Claim 13
