Biodegradable tissue retractor

Abstract

This invention describes novel 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.

1 . A device for the percutaneous application of a tissue-affixing article to tissue, comprising an obturator with a portion thereof for holding the tissue-affixing article, and a needle or cannula for percutaneous access of the obturator.  
   
   
       2 . The device of  claim 1 , further comprising a groove in the obturator to accommodate a suture.  
   
   
       3 . The device of  claim 1 , further comprising a notch in the obturator to hold the tissue-affixing article.
