20120239063 | MESH PATCH FOR USE IN LAPAROSCOPIC HERNIA SURGERY - A mesh patch for a laparoscopic hernia surgery, which includes a flexible mesh, an adhesion layer surface, and an anti-adhesion layer surface. The flexible mesh is formed of a thin layer of filament using a biocompatible polymer. The adhesion layer surface is disposed on a front surface of the mesh. The adhesion layer surface is coated with an adhesion inducing material to be fixedly attached to a peritoneum. The anti-adhesion layer surface is disposed on a rear surface of the mesh. The anti-adhesion layer surface is coated with an anti-adhesion material so as not to adhere to intestines in an abdominal cavity. The protection film is detachably attached to the adhesion layer surface and the anti-adhesion layer surface to protect the mesh. Here, the protection film is easily detached by a laparoscopic instrument, and has an adhesive strength such that the mesh is unfolded upon detaching. | 09-20-2012 |
