About the Fully Implanted Acclaim® Cochlear Implant
We believe the fully implanted Acclaim Cochlear Implant ("Acclaim CI") is a first-of-its-kind hearing device. 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.
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.
