Newly Published Peer-Reviewed Article Highlights Advances in Fully Implanted Cochlear Implant Technology

Envoy Medical in Position to Leverage its Sensor Technology

WHITE BEAR LAKE, MN, June 05, 2024 (GLOBE NEWSWIRE) --  Envoy Medical®, Inc. (“Envoy Medical”) (Nasdaq: COCH) today highlighted a recently published article in the Current Otorhinolaryngology Reports. The article, titled, “Fully Implanted Cochlear Implants,” was authored by Dr. Eric Babajanian, Dr. James Dornhoffer, and Dr. Colin Driscoll from Mayo Clinic in Rochester, Minnesota. Authors describe it as a review of the current state of fully implanted cochlear implants, including some of the challenges, limitations and breakthroughs.

The authors discuss the important influence middle ear implants (MEIs) have had on the development of fully implanted cochlear implants (FICI): “Many of the advancements in this area have contributed to the development of a FICI, primarily with the development of various microphone technologies that bypass the need for a separate external microphone.”

The article goes on to say that Envoy Medical’s fully implanted active middle ear implant (FI-AMEI), the Esteem® device, is the only fully implanted active middle ear implant currently commercially available. Envoy Medical believes its commercial experience with the Esteem fully implanted sensor technology provides it with an important competitive advantage in the marketplace.

“Envoy Medical is a leader in fully implanted hearing devices and we owe that leadership to our many years of experience with our fully implanted sensor technology,” said Brent T. Lucas, Envoy Medical’s Chief Executive Officer, “We have always believed that leveraging the outer and middle ear anatomy makes a lot more sense than sticking a microphone under the skin somewhere behind the ear.

“One of the benefits of leveraging the outer and middle ear anatomy is that the ear can still be used for other accessories and electronics, including headphones, ear buds, and even hearing aids,” added Lucas.

The article also notes the importance of an implantable power supply for a fully implanted cochlear implant. For its investigational fully implanted Acclaim® cochlear implant, Envoy Medical chose an architecture with a larger rechargeable battery in the pectoral region, versus a smaller rechargeable battery in the head.

“When faced with design choices, we felt that patients would rather go several days between charges. Our device was designed with patient preference in mind, and I believe we are headed in the right direction,” said Lucas.

About the Fully Implanted Acclaim® Cochlear Implant

We believe the fully implanted Acclaim Cochlear Implant (“Acclaim CI”) will be a first-of-its-kind fully implanted cochlear implant. Envoy Medical’s fully implanted technology includes a sensor designed to leverage the natural anatomy of the ear instead of a microphone to capture sound.

The Acclaim CI is designed to address severe to profound sensorineural hearing loss that is not adequately addressed by hearing aids. The Acclaim CI is expected to be indicated for adults who have been deemed adequate candidates by a qualified physician.

The Acclaim Cochlear Implant received the Breakthrough Device Designation from the U.S. Food and Drug Administration (FDA) in 2019. We believe the Acclaim CI was the first hearing-focused device to receive Breakthrough Device Designation.

CAUTION The fully implanted Acclaim Cochlear Implant is an investigational device. Limited by Federal (or United States) law to investigational use.

About the Esteem® Fully Implanted Active Middle Ear Implant (FI-AMEI)

The Esteem fully implanted active middle ear implant (FI-AMEI) is the only FDA-approved, fully implanted* hearing device for adults diagnosed with moderate to severe sensorineural hearing loss allowing for 24/7 hearing capability using the ear’s natural anatomy. The Esteem FI-AMEI hearing implant is invisible and requires no externally worn components and nothing is placed in the ear canal for it to function. Unlike hearing aids, you never put it on or take it off. You can’t lose it. You don’t clean it. The Esteem FI-AMEI hearing implant offers true 24/7 hearing.

*Once activated, the external Esteem FI-AMEI Personal Programmer is not required for daily use.
