Abstract
This invention describes methods and devices for stabilizing and retracting tissue during surgery, in particular internal tissue. Patches of material, preferably biodegradable, are adhered to tissue surfaces. By manipulation of the patches, for example directly with forceps, or via sutures attached to the patches, tissues can be retracted or otherwise manipulated with minimal trauma to the tissues. The method is especially useful in minimally-invasive surgery.
