9. Gently withdraw and remove needle.
Caution: If the guidewire must be withdrawn while the needle is
inserted, remove both the needle and wire as a unit to help prevent
the needle from damaging or shearing the guidewire.
10. If using a micropuncture set, gently withdraw and remove the small
sheath, while holding the standard guidewire in position.
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.
Warning: Hold thumb over exposed opening of sheath to prevent
3.
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.
