SYSTEM PREPARATION
1. Examine syringe. It has two plunger locks that must be depressed to advance
plunger. Tip of the syringe has a Luer slip fitting with a stopcock on the side
port. Air can be exchanged when stopcock is in "open" position, aligned with
syringe. (See Fig. 4)
2. Prepare syringe as follows:
a) With stopcock in "open" position, depress plunger locks and fully advance
plunger into syringe.
b) Turn stopcock to "closed" position.
c) Pull plunger back until it is locked into place at desired setting, creating a
suction.
d) Set prepared syringe aside until aspiration biopsy is desired.
3. Advance the device into the endoscope to determine preferred sheath
length. To adjust length, loosen the thumbscrew lock on the sliding sheath
adjuster and slide until the preferred length is attained. Note: The reference
mark for the sheath length will appear in the sliding sheath adjuster window.
(See Fig. 5) Tighten thumbscrew on the sliding sheath adjuster to maintain the
