7. The Squirt should be activated so heparinized saline from
the 20 ml reservoir syringe comes through the back end
cap of the hemostasis valve. (See Figure 7) When all the air
has been displaced, the back end cap should be tightened
onto the proximal end of the occluding wire, such that the
wire will slide through it.
Figure 7
8. Continue to activate the Squirt. This will ensure that a
liquid meniscus is at the distal segment of the hemosta-
sis valve. Attach the rotating adapter of the hemostasis
valve to the luer lock connector on the Fountain Infusion
Catheter, making sure that a liquid-to-liquid connection is
established. (See Figure 8)

When the connection is completed, tighten the back end
cap of the hemostasis valve onto the proximal end of the
occluding wire.
The wire protector cap can then be placed over the prox-
imal portion of the occluding wire and snapped into the
back end cap of the hemostasis valve (See Figure 8).
Priming the System with Therapeutic Solution
9. If the clinician wishes to conserve thrombolytic medica-
tion, the Squirt should be primed as instructed previously.
Turn the Squirt until the syringe is pointing down. (See Fig-
ure 9) Remove the priming reservoir syringe that is loaded
with sterile saline. Fill a syringe with thrombolytic solution.
Using the thrombolytic solution syringe, place a small
amount of thrombolytic solution into the female luer
connector of the Squirt. This will cause a small meniscus
of therapeutic solution to be placed on the female luer
connector. (See Figure 10)
SQUEEZE
Attach the syringe loaded with therapeutic solution. (See
Figure 10) Make sure that the connection is air-tight. If
any bubbles inadvertently enter the system they may be
removed by activating the trigger bar until all air bubbles
are out of the fluid path. (The dead space volume is
approximately 0.5 ml.)

10. Prime the entire system with therapeutic solution by
depressing the Squirt. The approximate system prime
volumes for each catheter are as follows:
45cm catheter - 1.0ml
90cm catheter - 1.5mls
135cm catheter - 2.0mls
Warning: All therapeutic agents to be infused must be
used according to the manufacturer's instructions for use.

11. The stroke volume ejected from the Squirt can be
adjusted from 0 - 1 ml of fluid by turning the knurled knob
located in the handle. When holding the Squirt with the
Sherlock connector pointed away from user, rotate the
knob clockwise to decrease stroke volume. Rotating the
knob in a counter-clockwise direction will increase the
stroke volume of the device. (See Figure 11) Adjust the
plunger tip to the amount of fluid to be infused with each
stroke by aligning the plunger ring with the gradation
marks on the Squirt's barrel. After activating the trigger
once the dosage is set and will deliver the same amount of
fluid each time the activation trigger is fully pulled.
