Appeal No. 2001-1418
Application 08/022,822
claims is hereby dismissed. Claims 39 through 41, 51 and 52
remain on appeal. Claims 36 through 38 and 42 through 50, the
only other claims pending in the application, stand withdrawn
from consideration pursuant to 37 CFR § 1.142(b).
THE INVENTION
The subject matter on appeal relates to “a patient therapy
heat exchange structure for placing against or for being worn on
the human body” (specification, page 1). Representative claims
39 and 51 read as follows:
39. A flexible heat exchange structure having a pair of
superposed sheets of flexible material sealed together to form a
plurality of fluid-conducting channels which tend to inflate and
decrease in width when a pressurized liquid passes through them,
and a manifold in fluid communication with the channels at one
end thereof which also tends to be inflated by the pressurized
liquid, the manifold having an undulating wall which is oriented
and dimensioned to decrease in dimension to the same degree that
the width of the channels decreases upon pressurization of the
structure.
51. A flexible heat exchange structure having a pair of
superposed sheets of flexible material sealed together in a
plurality of spaced apart discrete areas to form a fluid-
conducting channel which inflates and decreases in lateral
dimension upon pressurization by a fluid, and means sealing the
sheets together along an undulating line to form a chamber which
communicates with the channel and also inflates and decreases in
lateral dimension upon pressurization, the undulating line being
oriented and dimensioned to make the decreases in lateral
dimension substantially equal in the channel and in the chamber.
