Detachable Coil Reduces Blood Flow in Peripheral Vasculature

An innovative detachable hydrogel polymer embolic device provides greater filling capacity, packing density, and mechanical occlusion in the treatment of high-flow and challenging blood vessels, vascular malformations, and aneurysms.

The AZUR Detachable 35 with hydrogel coating is designed for use in the interventional radiologic management of arteriovenous malformations, arteriovenous fistulae, aneurysms, and other lesions of the peripheral vasculature. The Detachable 0.0889-cm coil deploys rapidly (in less than a second), offering physicians the flexibility to position and observe the behavior of the coil in the vasculature prior to detachment. The coil can be released with the simple press of a button; the hydrogel coating then undergoes limited expansion within the first three minutes, and fully expands within 20 minutes, offering nearly four times more filling volume than a platinum coil of the same size.


The AZUR Detachable 35 is compatible with 0.0965-cm lumen catheters, and can be retracted and repositioned until it is securely placed, reducing the risk of nontarget embolization and coil migration; the microporous expandable hydrogel is biologically inert and provides the subsequent scaffolding for natural tissue proliferation. The AZUR Detachable 35 is a product of Terumo Interventional Systems (TIS; Somerset, NJ, USA), and complements the existing AZUR product line, which includes Detachable 18 coils, Framing 18 coils (platinum only and in a complex three dimensional (3D) shape), Pushable 18 coils, and Pushable 35 coils.

"In our experience, the AZUR Detachable 35 is an excellent embolization system that is very capable of treating higher capacity lesions with fewer coils, while effectively minimizing risk of coil migration,” said Craig Greben, MD, chief of the division of vascular and interventional radiology at North Shore University Hospital (Manhasset, NY, USA). "The larger coil size is highly deliverable and provides us with added confidence in treating high-blood flow areas or particularly challenging anatomies.”
