MULTIPURPOSE IMPLANT WITH MODELED SURFACE STRUCTURE FOR SOFT TISSUE RECONSTRUCTION

摘要

Embodiments of a multi-purpose implant for use in surgery, such as for reconstruction of soft tissues, are disclosed. In some embodiments, the implant includes elastic polymer film made from a suitable biologically compatible polymer. The implant also includes a reinforcement element forms from a polyurethane mesh or other strong and stable woven or unwoven synthetic material. The reinforcement element can be fully enclosed by the film so that only the film comes into contact with the organs and tissues. Anti-adhesive properties or control over implant's integration into a body can be determined by the preset surface structure of the implant, while physical and mechanical properties, such as strength and elasticity of the implant, are obtained by virtue of reinforcement element geometry.

主权项

1. A multi-purpose surgical implant for reconstruction of soft tissues comprising:
an elastic film formed from a non-porous biologically compatible cross-linked copolymer based on 50-75 percent by weight multi-functional urethane (meth)acrylate oligomers and 20-50 percent by weight methacrylate monomers; the elastic film having:
a first smooth anti-adhesive surface, anda second relief surface opposite the first surface;wherein the elastic film is processed by soaking in isopropyl alcohol so as to block residual free radicals, thereby decreasing a risk of tissue reaction; and a reinforcement element partially enclosed inside the elastic film, wherein the reinforcement element does not contact body organs and tissue from the side of the first smooth anti-adhesive surface.
