Access the vessel and perform an angiogram using standard technique to measure the diameter of the vessel at the desired occlusion site.
Select a vascular plug with a diameter approximately 30-50% larger than the vessel diameter at the occlusion site. Ensure that the occlusion site has sufficient length so the deployed device length will not obstruct other vessels or anatomical structures.
| Deployment Steps | |
|---|---|
| 1 | Flush hoop dispenser and loader with sterile saline until fluid exits the distal tip to purge air from the loader. |
| 2 | Remove device (in loader) and delivery wire from the hoop dispenser. |
| 3 | Select a delivery catheter with an internal diameter that will accommodate the selected device. The original access catheter may be used if the internal diameter is sufficient for the selected device. Prepare the catheter for use (according to the manufacturer’s instructions for use). |
| 4 | Advance the delivery catheter over the guidewire until the distal tip of the catheter is at the distal edge of the occlusion site (according to the manufacturer’s instructions for use). |
| 5 | Remove the guidewire. |
| 6 | Insert loader into the delivery catheter through a Y-connector or hemostasis valve. |
| 7 | Allow blood backflow or aspirate the system to ensure air is purged from the catheter and loader. |
| 8 | Do not over tighten Y-connector to avoid damaging loader. |
| 9 | Advance the delivery wire to advance the device to the distal end of the delivery catheter. Do not twist or rotate the delivery wire during advancement to ensure device does not prematurely detach. |
| 10 | Hold delivery wire in place and slowly retract the delivery catheter to deploy the device at the occlusion site. |
| 11 | Verify position of the device using the radiopaque marker bands. ~ If unsatisfactory, stabilize the wire and re-advance the delivery catheter until the device is completely within the catheter. Reposition and deploy, or remove the device from the patient. ~ If satisfactory, attach the plastic visea to the wire and rotate the delivery wire counterclockwise until it separates from the device." |
| 12 | Remove delivery catheter and wire from the patient. |
