PEEL-APART SHEATH INTRODUCER INSTRUCTIONS
1. Advance the vessel dilator and sheath introducer as a unit over the exposed
wire using a rotational motion. Advance it into the vein as a unit, leaving at
least 2cm of sheath exposed. Note: Placement may be facilitated by making a
small incision to ease introduction of vessel dilator and sheath introducer.
Warning: Avoid vessel perforation.
2. Release the locking mechanism and gently withdraw the vessel dilator and "J"
wire, leaving the sheath in place.
3. Warning: Hold thumb over exposed opening of sheath to prevent air
aspiration. The risk of air aspiration is reduced by performing this part of the
procedure with the patient performing the Valsalva maneuver.
4. Insert catheter into the sheath. Advance the catheter through the sheath into
the vessel to the desired infusion site. Catheters should be positioned with the
catheter tip at the junction of the superior vena cava and the right atrium.
5. Verify correct catheter tip position using fluoroscopy, or appropriate technology.
Note: For arm-placed port, move the patient's arm to several positions
relative to the body. Using fluoroscopy, evaluate the effect of this movement
on the catheter tip location during each movement. If appropriate, reposition
the catheter so the tip is in the desired location. Note: Exercise care in the
placement of the catheter tip. Movement of the patient's arm in which the
system is implanted can cause displacement of the catheter tip away from the
desired location.
6. Grasp the two handles of the peel-apart sheath and pull outward and upward
at the same time.
7. Peel the sheath away from the catheter completely. Make sure the catheter is
not dislodged from vessel.
CATHETER TUNNELING PROCEDURE
1. Create a subcutaneous pocket using blunt dissection. Note: Do a trial
placement to verify that the pocket is large enough to accommodate the port
and that the port does not lie beneath the incision.
