This WEB™ by MicroVention device seals neck and conforms to aneurysm wall, it disrupts flow, protect aneurysm dome and provides scaffold for endothelialization.
It's a single, 3 Dimensional Intrasaccular implat made with Microbraid™ mesh of extremely fine DFT Nitinol-platinum wires. Suitable for unrupted and ruptured aneurysms.
Prior to detachment:
The micro-catheter has to be positioned at 2-3mm proximal to the proximal marker of the WEB device.
Make sure gold connectors of the pusher wires is free of contrast and blood.
Ensure RHV is locked
Always check connect WEB Detachment Controller and insert all the way.
Solld green light = device properly connected
Push detachment button Intermittent light/bips followed by solid green light = detachment ok
Verify detachment by advancing the pusher very slowly
If WEB device is detached, bring the pusher wire back into mc
Troubleshooting steps for suspected non-detachment:
1. Remove the WDc, wipe down the pusher and dry.
2. In case of sticky detachment, carefuly bring the mc to the base of WEB device to brace against it.
Bring the pusher slowly into the micro-Catheter .
Carefuly retract the micro-Catheter.
If step 1 & 2 do not work, try detaching the device with a new wDC.
If the previous steps do not work carefully remove the WEB device.
