Medtronic offers the lowest profile bone conduction hearing implant on the market. The unique design of the Alpha 2 MPO ePlus™ bone conduction implant eliminates the need for a post — or abutment — that sticks through the skin to hold the system in place. Instead, our magnetic titanium implant is secured to the skull, under the scalp. After surgery and healing, your skin remains intact and the sound processor with a magnetic spacer connects to the implant. The small, contoured processor offers the lowest profile and can be hidden under your hair.
The Alpha 2 MPO ePlus™ is the result of more than 10 years of research and clinical testing. The abutment-free bone anchored hearing aid provides an innovative hearing therapy designed for the way you live your life.
A simple outpatient surgery means you’ll be able to be fitted for your Alpha 2 MPO ePlus™ processor only four weeks after the operation. Check with your physician to determine the proper timing for fitting your magnetic processor.3,4,5,6
You’ll get up to two weeks’ of battery life. That’s more convenient and less expensive for you to maintain. The rechargeable battery system provides up to 1 year of battery life.7
The completely programmable digital system offers settings and features for different sound environments:
The Alpha 2 MPO ePlus™ system is designed to transfer amplified sound through the skin into the bone. We call this phenomenon Transcutaneous Energy Transfer (TET™).8
Alpha 2 MPO ePlus™ offers more sound amplification (gain) than any other magnetic transcutaneous system.9
Patients with Alpha 2 MPO ePlus™ magnetic implants can have MRI tests done safely — the Alpha 2 MPO ePlus™ implant has FDA conditional clearance for up to a 3 tesla MRI scan. The implant has the smallest transcutaneous MRI shadow at 5 centimeters.10,11 Your audiologist can explain this in more detail for you.
Compared to other magnetic devices, you can expect the highest performance with Alpha 2 MPO ePlus™ bone conduction hearing aid.
The Alpha 2 MPO ePlus™ system:
The Alpha 2 MPO ePlus™ device provides the highest functional gain, accompanied by outstanding sound quality. You can now experience our processor with 45 dB acoustic-mechanical gain, an increase of 16 dB.*

While our first-generation devices, the Sophono Alpha 1 and 2, are no longer sold, we continue to support patients with information and customer care. The most current processor available is the Alpha 2 MPO ePlus™ magnetic bone-anchored hearing system. Please check with your doctor and audiologist to see if the Alpha 2 MPO ePlus™ is right for you.
