The new Cochlear™ Nucleus® Profile Implant with Slim Modiolar Electrode (CI532) is designed to preserve hearing structures, boost hearing performance and is easy for surgeons to use


Centennial, Colo., (September 29, 2016) — Cochlear Limited (ASX: COH), the global leader in implantable hearing solutions, announces today the launch of the Cochlear Nucleus Profile Implant with Slim Modiolar Electrode (CI532).

The all new Slim Modiolar Electrode (CI532) is the world’s thinnest full-length perimodiolar electrode and comes on the most reliable implant (Nucleus Profile) available on the market today.1,2 The new electrode sits close to the hearing nerve, and its thin design is intended to protect and preserve the delicate structures of the inner ear in order to deliver the best hearing performance possible.3,4

Independent research shows electrode contacts positioned closer to the hearing nerve significantly improve hearing performance in patients with severe to profound hearing loss.5-8

“Our new Slim Modiolar Electrode is the latest perimodiolar array innovation in our portfolio of electrodes, and it really does make a difference for our customers and the surgeon,” said Tony Manna, President of Cochlear North America. “Feedback from leading surgeons around the world provided us with valuable insights as we developed this electrode. Cochlear now offers the world’s thinnest, full-length perimodiolar electrode, offering smooth and easy insertion during surgery and optimal hearing for our customer afterwards.”

The Slim Modiolar Electrode features a unique insertion mechanism that allows surgeons to tailor their electrode insertion approach for the individual patient’s needs, making insertion smooth and easy.9,10 It is compatible with round window, extended round window and cochleostomy insertion approaches and can be reloaded if required.

The addition of the Slim Modiolar Electrode further strengthens Cochlear’s market-leading portfolio of electrodes uniquely designed for preservation, performance and surgeon preference. The Nucleus implant portfolio offers surgeons and their patients a wide choice of electrodes for different types of hearing loss.
