Conception
14. Inventors Rowland and Vergano testified that on or
about 13 May 1991, they arrived at the idea of a three-lumen
catheter, where one of the lumens was for a guide wire, one for
injecting contrast fluid and one for containing a cutting wire
(RR 290, T 3).
15. Bryan Eddy allegedly made a sketch showing the cross
section and dimensions of the three-lumen catheter conceived by
Vergano and Rowland, whereby an engineering drawing was completed
on 14 June 1991 (RR 011, 1 7).
16. The engineering drawing does not show or describe the
elements of the count (Rowland Ex. 2013).
Actual reduction to Practice
17. By October 11, 1991, inventors Eddy and Vergano and lab
technician Heidi Bell (Bell), created prototypes of the three
lumen catheter (RR 007, 1 12; 012, 1 9; and 016, 91 7).
18. Eddy, Vergano and Bell all testified that the three
lumen catheter prototypes were as depicted in Figs. 1, 2, 4 and 9
of U.S. Patent 5,547,4694 , and includes a three-lumen catheter
body 11 having a lumen 17 for contrast fluid, a lumen 20 for a
cutting wire and a lumen 16 for a guide wire (Fig. 2), with
4 U.S. patent 5,547,469 (application 08/242,168) is the
parent case of Rowland's involved application, for which Rowland
has been accorded benefit (Finding 3).
