Preparing The System - PFM Medical Nit-Occlud Le VSD Mode D'emploi

English
Fig. 07: Kissing technique
• ( Fig. 07) Via the right femoral vein, advance a long 6F resp. 7F sheath with dilator via the guide wire until the dilator
meets with the JR or IM catheter in the IVC ("kissing technique"). Tighten the arteriovenous loop by pulling the guide
wire on both sides and fastening it with a clamp on the cone of the arterial catheter and the long sheath.
• ( Fig. 08) Carefully advance the long sheath through the VSD until its tip is placed in the ascending aorta. In doing so,
pull the arterial catheter back slightly. As soon as the long sheath reaches the ascending aorta, replace the arterial
catheter via the guide wire with a pigtail catheter.

Preparing the System

• Select the appropriate coil according to the size of the defect.
• Check that the sterile barrier is intact before removing the system from the packaging.
• Then open the system in a sterile environment.
• E nsure that the product is complete and not damaged in any way. If the product is not complete or shows signs of
damage, replace with a new product.
WA R N I N G
Damaged products should not be used under any circumstances.
• C heck that all screw connections are tight. Some screwed joints may have
been loosened by the sterilization process.
• C heck whether the single hand control is open. Should this not be preset,
push the clip on the hand control to "on", so that the single hand control can
be retracted without the spiral being drawn into the catheter.
• T he coil tip should project very slightly (2 mm) out of the implantation cath-
eter (Fig. 09) to make the coil feed process easier. If the coil slides back into
the implantation catheter while it is being moved, it should be repositioned
prior to insertion in the long sheath, as shown in Fig. 09.
• E nsure that you do not draw the coil tip behind the marker.
• F lush the system carefully with physiological saline solution via the side access of the Y-connector, and ensure that no
air is left in the system. It is advisable to flush the system throughout the entire procedure with a pressurised infusion
(heparinised physiological saline solution). The long sheath should be aspirated and flushed prior to insertion of the
implantation catheter.
