Alternative Preparation of the Snare
If the Delivery Catheter is already positioned within the vasculature, the provided
Introducer (located on the proximal end of the Snare and just distal to the Torque Handle) may
be used to position the Snare in the indwelling Delivery Catheter.
1. Remove the Snare from the hoop holder and inspect for any damage.
2. Move the provided Introducer (located on the proximal end of the Snare, just distal to the
Torque Handle) distally until the loops of the Snare are enclosed within the tubing portion of
the Introducer.
3. Insert the distal end of the Introducer into the hub of the indwelling Delivery Catheter until
resistance is felt. This will indicate the tip of the Introducer is properly aligned with the inner
lumen.
4. Hold the Introducer as straight as possible, grasp the shaft of the Snare just proximal to the
hub of the Introducer and advance the Snare until it is secure within the lumen of the
Delivery Catheter. The Introducer can be removed by first removing the Torque Handle and
pulling the Introducer off the proximal end of the Snare's shaft. After removing the
Introducer, re-apply the Torque Handle onto the shaft.
Snare Assisted Retrieval and Manipulation Suggestions:
1. If present, remove the indwelling delivery catheter.
2. If a guidewire is in a patient at the location of a foreign body, advance the Delivery Catheter
over the guidewire to the desired location. Then remove the guidewire and advance the
Snare through the Delivery Catheter. Alternatively, cinch one loop of the Snare over the
proximal end of the guidewire and advance the Snare and Catheter assembly into a guide
catheter or introducer sheath until the distal end of the Delivery Catheter is positioned
proximal to the foreign body.
3. If a guidewire is not present, pull the Snare into the distal end of the Delivery Catheter and
advance through a guide catheter or introducer sheath (not included) until it is positioned
proximal to the foreign body. Alternatively, collapse the Snare loops by pulling the device
into the distal end of the Introducer. Place the tapered end of the Introducer into the
proximal (hub) end of the Delivery Catheter, guide catheter or sheath and advance the
Snare forward maintaining constant contact between the Introducer and Delivery Catheter
hub.
NOTE: When attempting to utilize guide catheters or sheaths not specifically manufactured
for use with the Atrieve™ Vascular Snare, it is important to test product compatibility prior to
use.
4. Gently push the Snare shaft forward to completely open the loops outside of the Delivery
Catheter. The loops are then slowly advanced forward, and may be rotated if desired,
around the proximal end of the foreign body. Alternatively, the Snare may be advanced
beyond the target location and the loops brought back around the distal end of the foreign
body.
5. By advancing the Delivery Catheter, the loops of the device are closed to capture the
foreign body. (Note that attempting to close the loops by pulling the Snare into the Delivery
Catheter will move the loops from their position around the foreign body.)
6. To manipulate a foreign body, maintain tension on the Delivery Catheter to retain the hold
on the foreign body, and move the Snare and Delivery Catheter together to manipulate a
foreign body to the desired position.
7. To retrieve a foreign body, maintain tension on the Delivery Catheter and move the Snare
and Delivery Catheter assembly together proximally to, or into a guide catheter or sheath.
The foreign body is then withdrawn through or together with the guiding catheter or
introducer sheath. Withdrawal of large foreign bodies may require the insertion of larger
sheaths, guiding catheters, or a cut-down at the peripheral site.
Snare Assisted Removal of Fibrin Sheaths from Indwelling Catheters:
1. Using standard technique, prepare a femoral vein approach, advance the selected Snare to
the inferior vena cava or right atrium.
2. Advance a 0.035" guidewire through the end port (distal or venous port if more than one
lumen) of the indwelling catheter and into the inferior vena cava or right atrium.
3. Position one of the Snare loops around the guidewire.
4. Advance the Snare over the distal end of the indwelling catheter to a position proximal to
the fibrin sheath.
5. Close the Snare around the indwelling catheter and continue applying light traction while
gently pulling the Snare down toward the distal end of the indwelling catheter over the end
ports.
6. Repeat steps 4 & 5 until the indwelling catheter is free of fibrin sheath.
Snare Assisted Venous Canalization:
1. Introduce the Snare at a patent venous access site and position in the vasculature at the
desired site.
2. Open the Snare loops to provide a target to guide an entry needle into the desired venous
access site.
3. Introduce a guidewire through the needle and through the Snare loops. Remove the needle.
4. Close the Snare over the guidewire by advancing the Delivery Catheter.
5. Pull the guidewire into the desired location.
