5. Close Saline Pump door prior to attaching Saline Flush Line tip to the Saline bag.
Note: If Saline Flush Line tip is attached to Saline bag prior to placing Saline Flush Line
in the Saline Pump and closing the Saline Pump door, saline may leak.
6. Remove cap from tip of Saline Flush Line and attach to the saline source (Figure 8).
Ensure clamp on Saline Flush Line is open.

7. Remove Spike Adaptor and Sterile Water Vial from Syringe.
8. Load the filled Syringe into the Syringe cradle (Figure 9).

Note: Syringe luer should be positioned on top of the Syringe to push fluid out of
the Syringe.
9. Remove cap from Water Line luer and connect Syringe to Water Line by twisting
the luer on the prefilled Syringe. Pressure relief valve on Water Line should be
pointing down.
10. Using sterile technique, close clamp on Drain Line to ensure saline flows through
Delivery Device during the procedure (Figure 10).

11. Using sterile technique, remove Delivery Device from packaging tray.

Insert the Rigid Cystoscope Lens

The Delivery Device is compatible with a 4 mm, 30 degree, 30 cm length Storz®,
InnoView® or Richard-Wolf® rigid cystoscope lens. The lens provides direct or video
display visualization to help the physician position the Delivery Device needle within the
prostatic urethra.
Caution: The Delivery Device is compatible with a 4 mm, 30 degree, 30 cm Storz,
InnoView or Richard-Wolf cystoscopic lens. Use of other scope lenses may impact
performance of the Delivery Device.
1. Inspect and ensure lens is cleaned and prepared per manufacturer's instructions
prior to use.
2. Coat lens shaft near lens tip with lidocaine gel anesthetic or water soluble
lubrication to ensure smooth insertion into Delivery Device. Do not coat the lens
itself, as this may impede visualization (Figure 11).

3. Gently insert the lens into the lens port and advance into position until it snaps
into place.

Priming the Delivery Device

Warning: Point the Delivery Device tip away from patient or personnel during the
priming cycle. Vapor coming out of the tip is hot and can burn the skin.
1. Prime the Delivery Device using the following steps (Figure 12):
Figure 12. Steps for Activating Vapor Treatment.
A. Hold tip of Delivery Device over a liquid waste container.
Note: Ensure tip remains sterile.
B. Pull in Flush Activation Button (1) and Needle Deployment Button (2) until needle
is deployed. Release both buttons once needle is deployed.
C. Pull in Vapor Activation Button (3) and hold to activate the vapor until the display
screen indicates the priming cycle is complete (approximately 30 seconds).
D. Toward the end of the priming cycle, visually verify vapor is coming out of the
needle tip.
E. When priming cycle is complete, release the Vapor Activation Button and retract
the Needle by pushing upward on the Needle Retraction Button.
Caution: If finger is released from Vapor Activation Button before the priming cycle is
complete, vapor will automatically stop, and the priming steps will have to be repeated.
F. If the Vapor Activation Button is released before the end of the priming cycle,
repeat the priming cycle (steps A to E).
G. If priming cycle is not successfully completed, repeat steps a to e or replace
Delivery Device.

Perform the Pre-Treatment Vapor Cycle

1. Activate idle feature by running a pre-treatment vapor cycle. Idle feature heats
coil to keep water in a ready state so vapor delivery is immediate. If this step is not
completed, condensation may build up between treatments, which may lead to
insufficient treatment.
2. Pull in Flush Activation Button (1) Needle Deployment Button (2) and then Vapor
Activation (3) (Figure 12).
3. During pre-treatment vapor cycle, observe flush exiting tip.
4. When pre-treatment vapor cycle is complete, release the Vapor Activation Button
and retract the needle by pushing upward on the Needle Retraction Button.
