Abstract
Abstract A prosthesis to obturate a hernial canal includes a first part made of surgical material and configured in such a way as to deform under the effect of intra-abdominal pressure, to oppose such pressure elastically and to spread the force at the hernial canal over a portion of the inside face of the wall of a hernial cavity; and a second part for positioning in contact with the inside face of the wall of the hernial cavity and positioned annularly about the first part, whereby force exerted at the hernial canal is spread over a portion of the inside wall of the hernial cavity via the second part.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
A prosthesis to obturate a hernial canal, the prosthesis comprising, a first part comprising the body of the prosthesis and made of surgical material and being characterized in that said first part is configured in such a way as to deform under the effect of intra-abdominal pressure, to oppose said pressure elastically and to spread the force at the hernial canal over a portion of the inside face of the wall of a hernial cavity; and a second part for positioning in contact with the inside face of the wall of the hernial cavity, said second part being positioned annularly about said first part, whereby force exerted at the hernial canal is spread over a portion of the inside wall of the hernial cavity via said second part.
Claim 2
Dependent Claim
128 words
A prosthesis to obturate a hernial canal, the prosthesis comprising, a first part comprising the body of the prosthesis and made of surgical material and being characterized in that said first part is configured in such a way as to deform under the effect of intra-abdominal pressure, to oppose said pressure elastically and to spread the force at the hernial canal over a portion of the inside face of the wall of a hernial cavity; and a second part for positioning in contact with the inside face of the wall of the hernial cavity, said second part being positioned annularly about said first part, whereby force exerted at the hernial canal is spread over a portion of the inside wall of the hernial cavity via said second part.
Claim 3
Dependent Claim
51 words
A prosthesis according to claim 1, wherein the first part is configured in such a way as to extend through the hernial canal and to be folded down over the outside face of the wall of the hernial cavity for fixing of the first part on the borders of the aperture.
Claim 4
Dependent Claim
17 words
A prosthesis according to claim 1, wherein the prosthesis is constructed from one or more sheet materials.
Claim 5
Dependent Claim
111 words
A prosthesis according to claim 3, wherein the first part comprises a swollen head extended by a base to which it is joined, a third part which surrounds the first part at the point where the head and the base are joined, thereby forming a narrow neck at said point, and wherein the second part is toroidal in configuration and surrounds the first part at the narrow neck, and wherein the toroidal second part and the swollen head together bear against the inside face of the wall of the hernial cavity, thereby spreading the force exerted at the hernial canal over a portion of the inside wall of the hernial cavity.
Claim 6
Dependent Claim
18 words
A prosthesis according to claim 1, wherein the prosthesis is constructed of a fiber or a foam material.
Claim 7
Dependent Claim
22 words
A prosthesis according to claim 1, wherein at least one of the first and second parts is made from a non-absorbable material.
Claim 8
Dependent Claim
31 words
A prosthesis according to claim 6, wherein said first or second part is made from a material selected from the group consisting of cotton, linen, silk, polyamides, polyesters, fluoropolymers, and polyolefins.
Claim 9
Dependent Claim
37 words
A prosthesis according to claim 7 wherein said first or second part is made from a material selected from the group comprising polyhexamethylene adipamide, polyhexamethylene sebacamide, polycapramide, polydodecanamide, polyhexamethyleneisophtalamide, polyethylene terephthalate, polybutyl terphtalate, polytetrafluoroethylene, polypropylene and polyethylene.
Claim 10
Dependent Claim
23 words
A prosthesis according to claim 1, wherein at least one of the first and the second parts is made from an absorbable material.
Claim 11
Dependent Claim
36 words
A prosthesis according to claim 9, wherein said first or second part is made from a material selected from the group consisting of homopolymers and copolymers of glycolide, lactide, ε-caprolactone, p-dioxanone, trimethylene carbonate, 1,4-dioxepan-2-one, and poly(alkyleneoxalate).
