Cobra technology

coil and braid

React™ catheters feature an overlapping construction of a Nitinol COil + BRAid with variable stiffness. This unique design provides the ultimate combination of navigability, pushability and durability for aspiration therapy first-line approach or Solitaire™  thrombectomy + aspiration therapy.

of a coil

The coil technology (one continuous coil through entire catheter length) offers exceptional navigability1,2, past the ophthalmic artery and M1 segment.

Pushability of a brand

The braid technology offers optimal pushability1,2, thus greater support in tortuous anatomy and elongated vessels.

Durability of Nitinol

Using nitinol tip-to-tip (both coil and braid) enables the device to maintain its shape, therefore, providing superior durability when performing more than 1 pass.1,2
