Abstract
The present invention relates to a prosthesis (1) for hernia repair comprising a reinforcement layer (2), a first barrier layer (3) of anti-adhesion material covering at least a part of a surface of the reinforcement layer, and a second barrier layer of anti-adhesion material covering a remaining part of the surface of the reinforcement layer, the second barrier layer being formed of one or more flap member(s) (4).
Claims18
A prosthesis for treating a hernia defect in an abdominal wall comprising:
- at least one reinforcement layer, including a biocompatible porous material, the reinforcement layer including a first surface configured to face an abdominal wall and a second surface opposite the first surface, the reinforcement layer being delimited by an outer edge,
- at least one first barrier layer, including a biocompatible anti-adhesion material, the first barrier layer including a first surface and a second surface opposite the first surface of the first barrier layer, the first surface of the first barrier layer covering substantially an area of the second surface of the reinforcement layer, the second surface of the first barrier layer configured to face the abdominal cavity, the first barrier layer being delimited by an outer edge, and
- a first flap member formed of a piece of a first sheet of first biocompatible anti-adhesion material, the first flap member including a first surface and a second surface opposite the first surface of the first flap member, the first surface of the first flap member including an outer edge and free inner edge, the outer edge attached to the second surface of the at least one reinforcement layer or the second surface of the at least one first barrier layer, the free inner edge of the first flap member being free of the at least one first barrier layer and including at least one projecting tab extending inwardly therefrom, the projecting tab configured to lift the free inner edge of first flap member from the at least one first barrier layer.
A method of treating a hernia defect in an abdominal wall including:
- introducing a prosthesis into an abdominal cavity, the prosthesis including,
- at least one reinforcement layer, including a biocompatible porous material, the reinforcement layer including a first surface configured to face an abdominal wall and a second surface opposite the first surface, he reinforcement layer being delimited by an outer edge,
- at least one first barrier layer, including a biocompatible anti-adhesion material, the at least one first barrier layer including a first surface and a second surface opposite the first surface of the at least one first barrier layer, the first surface of the at least one first barrier layer covering substantially an area of the second surface of the at least one reinforcement layer, the second surface of the at least one first barrier layer configured to face the abdominal cavity, the at least one first barrier layer being delimited by an outer edge, and
- a first flap member formed of a piece of a first sheet of first biocompatible anti-adhesion material, the first flap member including a first surface and a second surface opposite the first surface of the first flap member, the first surface of the first flap member including an outer edge attached to the second surface of the at least one first barrier layer and a free inner edge of the first flap member, free of the at least one first barrier layer, and
- a second flap member formed of a piece of a second sheet of biocompatible anti-adhesion material, the second flap member including a first surface and a second surface opposite the first surface of the second flap member, the first surface of the second flap member including an outer edge attached to the second surface of the first flap member and a free inner edge free of the first flap member,
- positioning the prosthesis with the first surface of the reinforcement layer facing the abdominal wall,
- lifting the free inner edge of the first flap member to access a first protected space between the first flap member and the second surface of the at least one first barrier layer or the free inner edge of the second flap member to access a second protected space between the second flap member and the second surface of the first flap member, and
- fixating the prosthesis to the abdominal wall with a fixating means positioned within the first protected space or the second protected space, respectively.
