Abstract
A laminary material for preventing post-surgical adhesions, a corresponding kit, and a method for preparing such a laminary material. The laminary material includes an adherence layer for adherence to a desired site and an at least essentially parallel spacing layer attached to the adherence layer at a plurality of attachment points. The adherence layer includes a first polymeric film made of a first biodegradable polymer and an adherence coating. The spacing layer includes a second polymeric film made of a second biodegradable polymer. The adherence layer and the spacing layer define a cavity between the two layers, the cavity consisting of a plurality of interconnected compartments, which are defined by the attachment points.
Claims22
Laminary material for preventing post-surgical adhesions, comprising an adherence layer for adherence to a desired site and an at least essentially parallel spacing layer attached to the adherence layer at a plurality of attachment points, the adherence layer comprising a first polymeric film made of a first biodegradable polymer and an adherence coating, the first polymeric film having an outer surface facing away from the spacing layer and an inner surface facing towards the spacing layer, and at least part of the outer surface of the first polymeric film being coated with the adherence coating,
- the spacing layer comprising a second polymeric film made of a second biodegradable polymer, the second polymeric film having an outer surface facing away from the adherence layer and an inner surface facing towards the adherence layer,
- whereby the adherence layer and the spacing layer define a cavity between said two layers, the cavity consisting of a plurality of interconnected compartments, which are defined by the attachment points.
Kit for preventing post-surgical adhesions, comprising a laminary material and an adherence coating, the laminary material having an adherence layer for adherence to a desired site and an at least essentially parallel spacing layer attached to the adherence layer at a plurality of attachment points, the adherence layer comprising a first polymeric film made of a first biodegradable polymer, the first polymeric film having an outer surface facing away from the spacing layer and an inner surface facing towards the spacing layer,
- the spacing layer comprising a second polymeric film made of a second biodegradable polymer, the second polymeric film having an outer surface facing away from the adherence layer and an inner surface facing towards the adherence layer,
- whereby the adherence layer and the spacing layer define a cavity between said two layers, the cavity consisting of a plurality of interconnected compartments, which are defined by the attachment points,
- wherein the adherence coating is supplied separately or coated to at least part of the outer surface of the first polymeric film.
