Better together: Target coils and Neuroform Atlas™ by STRYKER

Tutorial

Target coils and Neuroform Atlas Better Together

Fluoro-saver marker

Open cells design

Distal and proximal radiopaque markers

Less than 12% metal coverage


Sizing and placement

Size is evaluated according to the proximal part of the parent artery

Choose diameter +1 

Ex : diameter 3,5 -> choose 4mm Atlas

Choose stent length providing coverage > 4mm on both sides of the neck


Prepare your device

- Insert to mid-valve

- Flush

- Push sheath to the bottom of the valve

- Push the device into the microcatheter until fluoro-saver marker

- Remove the sheath


Positioning

- Target the first artery that is more difficult to access

- Place the device exactly where you want it to deploy


Deployment

- Unsheath to deploy

- Once the Atlas markers have been deployed do not push the stent delivery wire forward

- The stent will deploy exactly where expected

- Pull back pusher wire

- Oversizing the Atlas may improve neck coverage : Atlas 4mm / Atlas 4,5 mm = Barrel effect


Recrossing maneuver

- Slightly reshape your wire in a straight direction

- Push and pull to cross the mesh


Coiling

- Push the sheath to the bottom of the valve

- Be careful not to bend around the detachment marker

- Pull out the sheath

- Insert until fluoro-saver markers

- Coiling safely with target coil

- Ensure you see the T marker shape


Coil detachment :

- 1 beep = contact

- Press button

- 3 beeps = detachment OK


Key points :

- Open cell design 

- Less than 12% metal coverage

- The stent will not foreshorten during deployment

- Choose a stent length that will provide at least 4mm coverage on both sides of the aneurysm neck

- Choose diameter +1

- Target the first artery that is more difficult to access

- The stent wil deploy exactly were expected

- Once the Atlas markers have been deployed, do not push the stent delivery wire, simply pull back on the microcatheter to unsheathe

- Coil safely with target coils
