                matrix material; naturally occurring extracellular matrix powder; naturally                   
                occurring extracellular matrix foam; woven naturally occurring extracellular                  
                matrix material; a nonwoven mat of naturally occurring extracellular matrix                   
                material; and naturally occurring extracellular matrix fragments.                             
                51.  The device of claim 50, wherein the naturally occurring extracellular                    
                matrix material comprises tissue selected from the group consisting of:                       
                vertebrate small intestin[e] submucosa; vertebrate liver basement membrane;                   
                vertebrate bladder submucosa; vertebrate stomach submucosa; vertebrate                        
                alimentary tissue; vertebrate respiratory tissue; and vert[e]brate genital                    
                tissue.                                                                                       
                55. A cartilage repair device for repairing damaged or diseased articular                     
                cartilage, the device comprising:                                                             
                a plug formed of naturally occurring extracellular matrix, the matrix                         
                being cured to have a strength sufficient to at least temporarily withstand the               
                compression and shear stress to which the articular cartilage is subjected;                   
                and                                                                                           
                an anchor configured to support and position the plug in a position                           
                which is proximate to healthy articular cartilage.                                            
                65.  The device of claim 55, wherein the naturally occurring extracellular                    
                matrix comprises comminuted SIS.                                                              
                92.  A cartilage repair device for repairing damaged or diseased articular                    
                cartilage, the cartilage having been prepared by forming an opening therein                   
                to remove the diseased or damaged portion, the device comprising:                             
                      an anchor;                                                                              
                      a second element having a density different from the density of the                     
                anchor;                                                                                       
                      wherein at least one of the anchor and second element is formed of                      
                naturally occurring bioremodelable collageneous matrix selected from the                      
                group consisting of: vertebrate small intestin[e] submucosa; vertebrate liver                 
                basement membrane; vertebrate bladder submucosa; vertebrate stomach
