taught or suggested at the time the invention was made to a
person having ordinary skill in the art a detent carried by the
handle to prevent continuous forward-rearward movement of the
movable portion of the handle from the implant capture position
to the implant release position.
In our view, when the control handle of Williams is
combined with either Lukic's, Braunschweiler's or Robinson's
device for delivering, positioning and releasing, within a
body lumen, a self-expandable implant, the semicircular
recesses 105, 110 taught by Williams would be located at the
implant release position and the implant capture position,
respectively. Thus, the semicircular recesses 105, 110 are
not readable on the claimed "detent" since they would not
prevent continuous forward-rearward movement of the movable
portion of the handle from the implant capture position to the
implant release position.
Additionally, it is our view that the combined teachings
of Robinson and Williams would have made it obvious at the
time the invention was made to a person having ordinary skill
