flushed with twice the indicated lumen volume using normal saline before
reestablishing heparin lock. Strict aseptic technique must be adhered to while
using and maintaining catheter.
INSTRUCTIONS FOR USE
Catheter Obturator Preparation
1. Flush catheter with saline solution, heparinized saline solution or sterile
water. NOTE: The catheter may be trimmed if a shorter length is required.
2. Attach a syringe with saline solution, heparinized saline solution or sterile
water to the Luer lock fitting of the catheter obturator holder.
3. Inject enough solution to wet the obturator surface entirely. This will
activate the AQ® hydrophilic coating, making the obturator surface very
lubricious.
4. Remove the obturator from its holder and insert it into the catheter,
locking it into position. NOTE: When placing a Twin Turbo-Flo Double-
Lumen Catheter, insert obturator into the hub marked "LARGE. " If the
catheter has been trimmed, advance the obturator only to the distal end
of the catheter. NOTE: If the surface of the obturator becomes dry after
removal from the holder, wetting with additional saline or sterile water
will renew the hydrophilic effect.
5. The catheter/obturator assembly can now be introduced as described in
the following section.
Catheter Placement (Fluoroscopic Method)
6. After prepping the access site, introduce the access needle into the
vessel. NOTE: The use of ultrasound is helpful to determine suitability for
vessel access and patency. The EchoTip® marking on the needle is used to
visualize the tip of the needle during vessel access.
7. Using fluoroscopic guidance, introduce the wire guide through the
needle and advance it 15-20 cm into the vessel.
8. Withdraw the needle, leaving wire guide in place. If necessary, enlarge the
puncture site with scalpel blade.
9. Introduce the Peel-Away introducer assembly (sheath and dilator) over
the wire guide. With a twisting motion, advance the assembly into the
vessel. (Fig. 1)
10. Using fluoroscopic control, determine the correct catheter length by
advancing the wire guide to the desired catheter tip location. Once the
wire guide tip is in proper position, mark the length by clamping forceps
onto the wire guide at the skin site.
11. Withdraw the wire guide and measure it from the forceps to the distal tip
to determine correct catheter length. Trim catheter if necessary. NOTE:
Remove obturator prior to trimming the catheter; reinsert for catheter
introduction.
12. Leaving the sheath in place, remove the dilator. (Fig. 2) NOTE: To prevent
inadvertent air aspiration after removing wire guide and dilator, place
thumb or finger over the cuffed proximal end of the sheath.
13. Introduce the catheter/obturator assembly into the sheath as far as
possible. NOTE: Resistance may be felt approximately 7 cm distal to the
catheter suture wing when introducing the assembly into the sheath due
to an increase in outer diameter. (Fig. 3)
