          Appeal No. 98-1316                                                          
          Application No. 08/420,896                                                  
          434 U.S. 1238 (1978).  With respect to the description                      
          requirement, the court in Vas-Cath, Inc. v. Mahurkar at 935                 
          F.2d 1563-64, 19 USPQ2d 1117 stated:                                        
               35 U.S.C. § 112, first paragraph, requires a                           
               "written description of the invention" which is                        
               separate and                                                           
               distinct from the enablement requirement.  The                         
               purpose                                                                
               of the "written description" requirement is broader                    
               than to merely explain how to "make and use"; the                      
               applicant must also convey with reasonable clarity                     
               to those skilled in the art that, as of the filing                     
               date sought, he or she was in possession of the                        
               invention.  The invention is, for purposes of the                      
               "written description" inquiry, whatever is now                         
               claimed.                                                               
               . . . drawings alone may be sufficient to provide                      
               the "written description of the invention" required                    
               by                                                                     
               § 112, first paragraph.                                                
               With these authorities in mind, we have carefully                      
          reviewed the original disclosure and fail to find descriptive               
          support for the recitation in independent claims 21 and 22                  
          that the fluid catheter has "a second end directly connected                
          to a dialysate reservoir container [i.e, element 28]."                      
          Contrary to such an arrangement, the specification expressly                
          states that the:                                                            
                    Fluid line 34 terminates at a catheter (not                       
               shown) that is in fluid communication with the                         
               peritoneal cavity of the patient 26.  [Page 10,                        
               lines 25-27; emphasis added.]                                          

                                          9
