Product Details

Deliverable Through 5F Selective Diagnostic Catheters (e.g. Imager II)

Deliverable Through 0.021" Lumen Microcatheters

Deliverable Through 0.021" Lumen Microcatheters

Detachment Mechanism

Simple Detachment via Interlocking Arms - No Handle Required

The interlocking connection is a simple coupling that remains attached while inside the lumen of the catheter. Detachment of the coil requires no additional devices, simply a push outside of the catheter.

Sizes and Shapes

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.

Literature

Dudeck, et al, Embolization of the Gastroduodenal Artery Before Selective Internal Radiotherapy:

A prospectively Randomized Trial Comparing Standard Pushable Coils with fibered Interlock Detachable Coils. CVIR, April 14, 2010.

Interlock Fibered IDC Occlusion System Number of Coils per Procedure Interlock Fibered IDC Occlusion System Number of Coils per Procedure

  • 83.6% of cases (19 of 23) achieved complete occlusion with one Interlock Fibered IDC Occlusion Coil.

  • A shorter procedure time was observed for procedures utilizing detachable coils when compared to pushable coils.

  • No coil migration was observed in the detachable coil group, whereas one incidence of migration was observed in the pushable coil group
