The Interlock-35 Fibered IDC Occlusion System is designed to offer precision and control in combination with powerful thrombogenicity. Compatible with 5F selective diagnostic catheters, the 0.035" large volume and heavily fibered system is beneficial especially in large, proximal vessels. 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.
The Cube shape is designed to provide circumferential wall apposition and framing capability. The cube shape also provides cross-sectional filling, beneficial for use in aneurysms and packing large vessels.

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.

Catheter Compatibility


The Interlock-35 Coil is recommended for use with a 5F (1.70mm) diagnostic catheter - 0.035 in (0.89mm) or 0.038 in (0.97mm) inner lumen, such as Imager™ II Catheter without side flushing holes. Use of soft-wall catheter is not recommended due to significant resistance that could be encountered during advancement.

Physicians should exercise their clinical judgment in selection and use of catheters. Refer to the instructions for use for each product listed. Manufacturers may make changes to their catheters without notice which may impact their suitability for use with Interlock-35 Fibered IDC Occlusion System. Boston Scientific Corporation provides no warranty for use of third party catheters with its products. The use of other diagnostic catheters may result in an inability to deliver, deploy, or recapture the device.

Do not attempt to use the Interlock-35 Coil with a soft-walled delivery catheter, such as the Terumo Glidecath™ Catheter or the Angiodynamics SoftVu™ Catheter. Due to the coil’s high radial force and dense fibering configuration, significant resistance will be encountered when advancement through a soft-walled delivery catheter is attempted.

Coil Preparation

Interlock Coil Prep
Flushing the luer attached to the carrier hoop enables coil hydration before insertion into the catheter.
Interlock Coil Prep
Side holes in the distal portion of the introducer sheath allow hydration through the rotating hemostatic valve (RHV or touhy-bourst valve). This hydration helps to limit thrombus formation in the catheter lumen during coil advancement.
Interlock Coil Prep
Nitinol pusherwire designed for control, strong pushability, and resistance to kinking when advancing and retracting the coil.
