Interlock-18 Fibered IDC Coil Deployment

The Interlock-18 Fibered IDC Occlusion System is designed to offer precision and control, in combination with thrombogenicity and flexibility. Compatible with 0.021" lumen microcatheters, the 0.018" fibered microcoil system is beneficial especially in complex and distal peripheral vasculature, and is available in a wide variety of shapes and sizes. The interlocking arms allow the coil to be advanced and retracted before final placement, for security in embolization procedures.

Product Details


The 2D Helical shape is designed to provide optimal anchorability, as the helical shape allows the coil to be in constant, consistent contact with the wall of straight or tapered vessel.
The Diamond shape is designed to maximize occlusive power by tapering the distal and proximal ends of the coil, maximizing cross-sectional flow disruption.

Coil Delivery

Interlock-18 coils feature a clear and visible detachment zone, with the ability to retract and reposition the coil before final placement. A radiopaque marker is included 3cm proximal to the interlocking arms, for additional visualization benefit.

Double Marker Microcatheter

Double Marker Microcatheter
Coil Delivery 1
The Direxion microcatheter is available with two visible radiopaque markers 30 mm distance apart, for visualization aid when the catheter tip is buried into a coil nest.
Coil Delivery 2
Interlock and IDC detachable coils have a radiopaque marker band on the delivery wire 30mm proximal to the interlocking arms. 
Coil Delivery 3
As the coil is advanced, watch as the proximal coil marker approaches the proximal microcatheter marker. Proximal to this point, the coil can still be retracted and repositioned.
Coil Delivery 4
When the proximal coil marker passes the proximal microcatheter marker, the coil has been deployed into the vessel.

Fibered for Thrombogenicity Power

Fibered for Thrombogenicity Power
Interlock's dense network of fibers
  • Every coil contains multiple dense networks of synthetic fibers, each designed to catch blood cells and propagate the formation of thrombus.

  • A close-up image of synthetic fibers (left) shows that the structure of the fiber strands are robust, yet porous, allowing for rapid thrombosis.

In an independent head-to-head bench-top thrombogenicity evaluation of same-sized (diameter and length) peripheral embolization coils between brands:

  • Interlock-18 coils reached an occlusion test endpoint nearly 3 times faster than equivalent-size Covidien Concerto coils

  • Interlock-18 coils reached the occlusion endpoint faster than Penumbra Ruby coils; Ruby coils took over 50% longer to reach the same endpoint, using equivalent size, one-to-one coils

Catheter Compatibility

The Interlock-18 Fibered IDC Occlusion System is designed to be delivered  through a  0.021" inner lumen microcatheter [0.53 mm], such as the Direxion small-lumen microcatheter.

Case Study

Coiling 6-cm Internal Iliac Artery Aneurysm

Case performed by Saam Tabar, MD, Interventional Radiologist at Veterans Affairs Hospital, Washington, DC.

A 63-year-old male patient presented with a large, 6-cm traumatic aneurysmal arteriovenous fistula of the left internal iliac artery.

Results from case studies are not necessarily predictive of results in other cases. Results in other cases may vary.
