Passive Middle Ear Implants
Connecting What Belongs Together
MED-EL's mission is to overcome hearing loss as a barrier to communication and quality of life. This is best fulfilled by offering a complete portfolio of hearing implants. That's why we've developed high-precision passive middle ear implants and added them to our portfolio.
We’ve put over two decades of experience in hearing solutions and ear surgery into our range of passive middle ear implants. The result? A sophisticated design that combines efficient sound transmission with easy surgical handling. And with 11 adaptable prostheses to choose from—each in a variety of sizes—there’s a solution to suit both your surgical preferences and your patient’s individual anatomy.
- Sophisticated design
- Created by hearing experts
- Adaptable to individual anatomy
Optimal Sound Conduction
Our range of passive middle ear implants is made up of prostheses for both tympanoplasty and stapes surgery. The tympanoplasty prostheses act as a partial or total replacement for the ossicular chain. Our stapes prostheses replace the stapes arch or stapes arch and incus in cases with a fixed stapes footplate.
Like all of MED-EL’s hearing solutions, our passive middle ear implants are built with hearing performance in mind. Made of titanium, they are both lightweight and extremely stiff for optimal sound conduction to the oval window and into the inner ear, so that your patients can experience the joy of hearing.
We’ve drawn on all our expertise in otology to make surgery with each and every one of our passive middle ear implants as straightforward as possible. Not only are they designed to give you optimal visibility of the surgery but they are also very balanced for stability and easy handling. And all our implants can be adapted to the patient’s individual anatomy during implantation for extra flexibility.
Intraoperative visibility is key in all our passive middle ear implants. Our tympanoplasty implants have generous openings in the headplate so you can easily see the coupling point. In our stapes implants, we used a slim design that allows for a full view of the footplate and the long process of the incus. All this helps make your surgical experience as simple as possible.
Every middle ear anatomy is unique. That’s why our passive middle ear implants offer flexibility, even during surgery. Every prosthesis has a bendable shaft that is easy to adapt to the individual anatomy. In our tympanoplasty implants, you can even bend the headplate to accommodate the handle of the malleus—no special equipment needed.
Lightweight and Balanced
We wanted the general handling and intraoperative placement of our implants to be as simple as possible so we designed all of our implants with balance and the equal distribution of weight in mind. This makes all of our prostheses inherently stable, and therefore easy to handle during surgery.
It’s not just our implants that are easy to use: Even the packaging is practical. All our prostheses and Sizer Kits come in a small but sophisticated red box. The sliding design and in-built guidelines help make setting up for surgery simple.
Peace of Mind
Like all MED-EL implants, our passive middle ear implants allow easy MRI scans without surgery, discomfort, or hearing downtime and are MRI conditional up to 7.0 Tesla. Made of strong, light, and biostable titanium, every prosthesis is biocompatible for your patients’ safety.

We have 11 different passive middle ear implants to choose from, including tympanoplasty and stapes prostheses, along with several Sizer Kits. They all come in various sizes so they don’t just fit the individual anatomy of each patient, but also your surgical preferences in terms of the type of coupling and design.
Our mXACT PRO, mXACT, mCLIP ARC, and mCLIP partial prostheses are used as a replacement for the ossicular chain when the stapes superstructure is still present. We also offer a partial prosthesis Sizer Kit to help you find the right implant length.
mCLIP ARC Partial
mXACT PRO Partial
mCLIP ARC Partial Prosthesis
The mCLIP ARC partial prosthesis has a design unique to MED-EL. The symmetrical clip and concentric alignment of the circular headplate on the ball-joint make surgical handling simple while allowing easy positioning on the stapes. It’s also filled with fine mechanical details: The combination of clip and ball-joint makes it both stable and very flexible. And the innovative micro ball-joint can follow the quasistatic movements of the eardrum to prevent peaks in pressure.
mXACT PRO Partial Prosthesis Kit
With the mXACT PRO partial prosthesis kit, you can easily and precisely set the appropriate implant length using the unique click mechanism within the red packaging—there are no pre-set increments and no extra tools needed. You can also rotate the bell to align it with the head plate and adapt it to the individual patient anatomy (stapes/handle of the malleus). Sterile sizers of different lengths are included in the same kit and are easily removed for intraoperative measurement without trimming.
mXACT Partial Prothesis
Thanks to the round, bell-shaped coupling structure, the mXACT partial prosthesis sits securely on the head of the stapes. The even weight distribution adds to the stability of the implant, which is also useful for placement and handling. The headplate and shaft are bendable, giving you flexibility to adapt the implant to the patient's anatomy during surgery. It also has generous openings in the headplate for optimal visibility of the coupling structure.
mCLIP Partial Prosthesis
The mCLIP partial prosthesis uses a clip coupling structure with harmonized forces to ensure stable placement on the head of the stapes. It has a bendable shaft and headplate, as well as a symmetrical clip design for intraoperative flexibility. The generous openings in the headplate mean you always have a clear view of the coupling structure, and the even weight distribution ensures easy handling.
Partial Prosthesis Sizer Kit
Find the right implant length with the partial prosthesis Sizer Kit. Each kit contains five sizers of differing lengths to help you easily measure the distance between the head of the stapes and the eardrum. This lets you determine the functional length of the appropriate implant. Made of polypropylene, the sizers are sterile, intuitive to use, and easily removed from the box.
Our total prostheses act as a complete replacement for the ossicular chain when only the stapes footplate is present. Choose betweem the mXACT PRO total prosthesis, mXACT total prosthesis offcenter, and the mXACT total prosthesis center depending on your personal preferences and your patient’s anatomy. There is also a total prosthesis Sizer Kit to help find you the right implant length.
mXACT PRO Total
mXACT PRO Total Prosthesis Kit
With the mXACT PRO total prosthesis kit, you can easily and precisely set the appropriate implant length using the unique click mechanism within the red packaging—there are no pre-set increments and no extra tools needed. The cannulated footing and balanced weight distribution allow stable placement on the stapes footplate. Sterile sizers of different lengths are included in the same kit and are easily removed for intraoperative measurement without trimming.
mXACT Total Prosthesis Offcenter
The mXACT total prosthesis offcenter has a cannulated footing for added stability on the stapes footplate. A reinforced cylindrical shaft near the headplate prevents unintentional bending, whereas the lower part of shaft is thinner and allows for easy bending. The headplate can also be bent to accommodate the handle of the malleus. The headplate also has generous recesses for a good view of the stapes footplate.
mXACT Total Prosthesis Center
The mXACT total prosthesis center has a cannulated footing for added stability on the stapes footplate. A reinforced cylindrical shaft near the headplate prevents unintentional bending, whereas the lower part of shaft is thinner and allows for easy bending. The headplate can also be bent to accommodate the handle of the malleus. The headplate also has generous recesses for a good view of the stapes footplate.
Total Prosthesis Sizer Kit
Find the right implant length with the total prosthesis Sizer Kit. Each kit contains seven sizers of differing lengths to help you easily measure the distance between the stapes footplate and the eardrum to determine the functional length of the appropriate implant. Made of polypropylene, the sizers are sterile, intuitive to use, and can be easily removed from the box.
Our stapes prostheses act as a replacement for the stapes arch, or stapes arch and incus in cases with a fixed stapes footplate. There are four different stapes implants to choose from—mFIX, mLOOP, mZAM, and mAXIS—depending on your patient’s anatomy and your personal preference.
mFIX Stapes Prosthesis
The mFIX stapes prosthesis has a space-saving design that allows enough room between the implant and the posterior auditory canal wall. Handling is easy: You can slide it onto the long process of the incus without the need for crimping, and the even weight distribution makes it easy to position in the middle ear. For extra flexibility during surgery, the shaft can be adapted to the patient’s anatomy.
mLOOP Stapes Prosthesis
With lengths of up to 10 mm, the mLOOP stapes prosthesis is ideal for attaching to both the incus or the malleus. The off-set band loop and bendable shaft allow for flexibility during surgery. With a clear view of the stapes and even weight distribution, surgical handling is simple.
mZAM Stapes Prosthesis
The mZAM’s extremely slim design gives you optimal visibility when placing the implant. The off-set band loop and bendable shaft allow for flexibility during surgery. With balanced weight distribution, the mZAM is stable and easy to handle.
mAXIS Stapes Prosthesis
The loop of the mAXIS is wider than our other stapes prosthesis, which is designed to reduce pressure on the incus, while the perforations ensure gentle crimping. For flexibility during surgery, it has an offset band loop and bendable shaft that can be adapted to the patient’s anatomy. Thanks to the even weight distribution, the mAXIS is both stable and easy to handle.
