Appeal No. 2000-1948 Page 8
Application No. 08/751,087
includes a pair of semicircular recesses 105, 110, situated
towards the distal end 115 and proximal end 120 of the
catheter handle tool, respectively, with the recesses engaged
by laterally projecting semicircular locking arms 303, 306 on
the thumbswitch 100. The
locking arms serve to retain the thumbswitch along the slot at
the recesses.
The plunger and flush port assembly of Williams includes
a reciprocating plunger 180 having a distal end 185 that is
attached to a sliding flush port assembly 190. The flush port
assembly 190 is attached to the outermost retractable sheath
10. The sheath 10 is moved relative to the underlying stent
delivery catheter 20, in order to expose the underlying stent
at the distal end of the catheter. The flush port assembly
190 is attached to the thumbswitch 100, via posts 172, 174.
Reciprocating the thumbswitch along the track formed by slot
90 will also reciprocate the sliding flush port assembly along
the slot, and therefore create relative motion between the
retractable sheath 10 and the underlying stent delivery
catheter 20 to retract sheath 10 from catheter 20.
