the guidewire. Thereafter, the physician
could
hold the guidewire in place at the proximal
end while deflating the captivation balloon
and removing the balloon on a stick or
captivation device.
Euteneuer further testified that at the meeting
Keith drew the concept on a board and they discussed various
issues with the system (KR-43, 44). Also, during the meeting
Euteneuer made a list of the concepts generated and discussed
(JPX-2; KR-44). Item 3 on the list refers to Keith's "balloon
on a stick" concept and reads "balloon along side a wire with
a wire in the balloon." Euteneuer explained that (KR-45):
The "balloon along side a wire" phrase
refers to the captivation balloon being
positioned along side the guidewire within
the guide catheter. The "with a wire in the
balloon" indicates that the over-the-wire
balloon dilatation catheter is still within
the guide catheter and thus having the
guidewire extending therethrough.
In view of this evidence, we conclude that Keith et
al. have established a conception of the invention of count 2
as of October 3, 1988. Although not supported by drawings of
any apparatus to be used, the invention in issue is a method,
