          recall seeing the                                                           
          CX-65, 66 notebook pages in December 1988, but rather based                 
          his                                                                         


          statement as to the date of the meeting on his looking at the               
          notebook pages when his declaration was being prepared (CR-                 
          88).  We do not regard this evidence as sufficient to                       
          corroborate Coelho's testimony as to the date of the                        
          brainstorming meeting.                                                      
                    The first notebook page, CR-65, is titled "Rapid                  
          exchange guide wire for balloon exchange," and states at the                
          top:                                                                        
                                         I.                                           
                    Concept:  to build a guide wire with an                           
                    extendable section (wire mesh or balloon)                         
                    which would open and secure itself to the                         
                    guide catheter.  [T]his would lock in place                       
                    the guide wire at the distal end of the                           
                    guide catheter so that a balloon catheter                         
                    may be easily exchanged.                                          
          This is followed by two drawings, showing a "hypotube" with a               
          ring and spring arrangement, and a wire attached to the ring
