          Application No. 08/591,506                                                  


               Considering first the § 103 rejection of claim 1, this                 
          claim calls for a catheter system that includes an expandable               
          stent capable of permanent deformation when expanded                        
          releasably attached to the inflatable portion of a catheter by              
          a bond having certain capabilities, including the capability                
          “of separating from said stent member and remaining with said               
          inflatable portion . . . upon inflation of said inflatable                  
          portion to permit deployment of said stent member” (claim 1,                
          emphasis added).                                                            
               Lau, the examiner’s primary reference, pertains to a                   
          catheter system comprising a catheter member 11 having an                   
          inflatable portion 14 and an expandable stent 10, capable of                
          permanent deformation when expanded, attached to the                        
          inflatable member.  Lau describes the attachment of the stent               
          to the inflatable portion of the catheter as follows:                       
               A variety of means for securing the stent to the                       
               expandable member on the catheter for delivery to                      
               the desired location are available.  It is presently                   
               preferred to compress the stent onto the balloon.                      
               Other means to secure the stent to the balloon                         
               include providing ridges or collars on the                             
               inflatable member to restrain lateral movement, or                     
               using bioresorbable temporary adhesives.  [Column 2,                   
               lines 18-25.]
