Abstract
Abstract The device, which is intended to be implanted in a position approximately homologous to the obstructed natural tube to bring the respective ovary closer to the uterus, comprises a generally tubular envelope having a wider portion intended to receive the respective ovary, a narrower portion intended to extend through the wall of the uterus, and a connecting portion interposed between the wider portion and the narrower portion and having a general funnel-shaped configuration converging towards the narrower portion.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
An implant device for the surgical treatment of infertility due to obstruction of uterine tubes, intended to be implanted in a position approximately homologous to the obstructed natural tube to bring the respective ovary closer to the uterus, comprising a generally tubular envelope having a wider portion intended to receive the respective ovary and a narrower portion intended to extend through the wall of the uterus, said narrower portion having a length corresponding substantially to a thickness of the wall of the uterus, said wider portion and said narrower portion being immediately adjacent one another and connected together in a general funnel-shaped configuration converging towards said narrower portion.
Claim 2
Dependent Claim
108 words
An implant device for the surgical treatment of infertility due to obstruction of uterine tubes, intended to be implanted in a position approximately homologous to the obstructed natural tube to bring the respective ovary closer to the uterus, comprising a generally tubular envelope having a wider portion intended to receive the respective ovary and a narrower portion intended to extend through the wall of the uterus, said narrower portion having a length corresponding substantially to a thickness of the wall of the uterus, said wider portion and said narrower portion being immediately adjacent one another and connected together in a general funnel-shaped configuration converging towards said narrower portion.
Claim 3
Dependent Claim
36 words
A device according to claim 1, wherein said narrower portion is provided, at the end opposite said wider portion, with an enlarged mouth portion which opens towards the wall of the uterus in the implant position.
Claim 4
Dependent Claim
13 words
A device according to claim 2, wherein said mouth portion is generally flared.
Claim 5
Dependent Claim
37 words
A device according to claim 1, wherein said narrower portion comprises at least two elements joined together telescopically, whereby the length of said narrower portion is selectively adaptable to the thickness of the wall of the uterus.
Claim 6
Dependent Claim
24 words
A device according to claim 1, wherein said narrower portion has an axial cavity whose sectional area decreases gradually away from said wider portion.
Claim 7
Dependent Claim
31 words
A device according to claim 1, wherein said narrower portion has an axial cavity which has diametral dimensions of the order of 2-4 mm at the end opposite said wider portion.
Claim 8
Dependent Claim
40 words
A device according to claim 1, wherein said narrower portion has associated therewith tab means extending in a substantially radial direction relative to the device and having holes for the fixing of the device in the implant position by sutures.
Claim 9
Dependent Claim
33 words
A device according to claim 1, wherein said narrower portion has associated therewith a collar member which rests on the outer surface (perimetrium) of the wall of the uterus in the implant position.
Claim 10
Dependent Claim
13 words
A device according to claim 8, wherein said collar member is substantially flexible.
Claim 11
Dependent Claim
26 words
A device according to claim 1, wherein said wider portion is provided internally with pointed projections able to promote the breaking of the follicle during ovulation.
Claim 12
Dependent Claim
24 words
A device according to claim 1, wherein said wider portion has holes for the fixing of the device in the implant position by sutures.
Claim 13
Independent Claim
136 words
A method for the surgical treatment of infertility due to tubal obstruction, comprising the steps of: removing at least one of the ovaries from its position, separating it from its respective tube; implanting in a position approximately homologous to the respective tube an implant device comprising a generally tubular envelope with a wider portion and a narrower portion joined together in a generally funnel-shaped configuration converging towards the narrower portion, arranging said narrower portion in a position in which it extends through the wall of the uterus and said wider portion outside the uterus, said narrower portion having a length corresponding substantially to a thickness of the wall of the uterus, and disposing said at least one ovary inside the wider portion of the implant device such that the ovary is moved closer to the uterus.
Claim 14
Independent Claim
136 words
