Abstract

The invention concerns a prosthesis obturating device to obturate a hernial canal comprising, a part (1) made of sheet material for extending through the hernial canal and being characterized in that this first part is extended, at its end that is to be adjacent to the hernial cavity, inside this hernial cavity, by a second part, also made of sheet material and for covering the internal orifice of the hernial canal.

Claims

1. A prosthesis obturating device to obturate a hernial canal, comprising:

a first part comprising a sheet material, said first part being adapted to obturate said hernial canal upon insertion of said obturating device in said hernial canal,

a substantially conical second part comprising a sheet material fixedly attached to said first part, said second part being adapted to provide a barrier at an internal orifice of said hernial canal upon insertion of said obturating device in said hernial canal,

wherein, upon insertion of said obturating device in said hernial canal, said first part is positioned within a hernial cavity and extends through said hernial canal, thereby obturating said hernial canal, and said second part is positioned within a hernial cavity, thereby forming a barrier at the internal orifice of said hernial canal.

2. A device according to claim 1, wherein the first part is hollow.

3. A device according to claim 1, wherein the first part is cylindrical or conical.

4. A device according to claim 1, wherein the first part is formed by rolling a prosthetic sheet on itself about 360°

and connecting two adjacent edges of the rolled sheet.

5. A device according to claim 1, wherein the first and the second parts are formed of concentrical conical structures having concavity directed in the same direction.

6. A device according to claim 5, wherein the conical structures forming the first and the second parts are connected at tips of said conical structures.

7. Device according to claim 5, wherein the conical structure forming the second part has a greater expansion than the conical structure forming the first part.

8. A device according to claim 6, wherein the first part is extended at an end opposed to the second part by a base, at least part of which projects outwards from said first part in a plane substantially perpendicular to the axis of said first part.

9. A device according to claim 1, wherein at least one of the first and second parts is made from a non-absorbable material.

10. A device according to claim 9, wherein said non absorbable material is selected from the group consisting of cotton, linen, silk, polyamides, polyesters, flouropolymers and polyolefins.

11. A device according to claim 10, wherein said non absorbable material is selected from the group consisting of polyhexamethylene adipamide, polyhexamethylene sebacamide, polycapramide, polydodecanamide, polyhexamethyleneisophtalamide, polyethylene terephtalate, polybutyl terphtalate, polytetraflouroethylene, polypropylene including isotactic and syndiotactic polypropylene, blends composed predominately of isotactic or syndiotactic polypropylene blended with heterotactic polypropylene and polyethylene, and blends thereof.

12. A device according to claim 1, wherein at least one of the first and the second parts is made from an absorbable material.

13. A device according to claim 12, wherein said absorbable material is selected from the group consisting of homopolymers and copolymers of glycolide, lactide including L-, D-, and mixtures, ε

-caprolactone, p-dioxanone, trimethylene carbonate, 1,4-dioxepan-2-one, and poly(alkyleneoxalate).
