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 (PMEIs) 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 16 adaptable prostheses to choose from, 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.
Straightforward Surgery
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 designed for easy handling. And all our implants can be adapted to the patient’s individual anatomy during implantation for extra flexibility.
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 at 1.5, 3.0, and 7.0 Tesla. Made of strong, light, and biostable titanium, every prosthesis is biocompatible for your patients’ safety.
- Made from titanium
- 10-year sterile shelf life
- MRI conditional at 1.5, 3.0, and 7.0 Tesla
For Everyone
We have 16 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.
Partial Prostheses
Our mCLIP ARC, mGRIP, mXACT PRO, mDISC, mXACT, and mCLIP Partial Prostheses are used as a replacement for the ossicular chain when the stapes superstructure is still present.

mCLIP ARC Partial Prosthesis
The mCLIP ARC Partial Prosthesis brings together flexibility and stability. The combination of the clip and the innovative micro ball-joint enables the mCLIP ARC Partial Prosthesis to follow the quasistatic movements of the eardrum and sit securely on the stapes. This prosthesis is designed to cause fewer peaks in pressure, resulting in lower extrusion rates and better long-term hearing results. This is thanks to the flexibility of the headplate, which ensures that it always lies flat on the eardrum and can also reduce tension in the annular ligament.
The symmetrical clip, the round headplate, and the concentric position of the micro ball-joint make surgical handling simple while allowing for easy positioning on the stapes. And thanks to the tiltable headplate, there is always a clear view of the clip and the stapes.
mGRIP Partial Prosthesis
The headplate of the mGRIP Partial Prosthesis has a unique design with two integrated spikes that can prevent the cartilage from migrating, thereby supporting long-term stability of the reconstruction. The round, bell-shaped coupling structure ensures ideal contact between the prosthesis and the stapes. This simplifies placement and minimizes the risk of necrosis. Additionally, the coupling structure allows the prosthesis to rotate slightly on the head of the stapes to compensate small movements of the tympanic membrane.
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.
mDISC Partial Prosthesis
With a functional length of only 0.2 mm, the mDISC Partial Prosthesis can be used for shallow or radical cavities. The round, bell-shaped coupling structure ensures ideal contact between the prosthesis and the stapes. This simplifies placement and minimizes the risk of necrosis. Additionally, the coupling structure allows the prosthesis to rotate slightly on the head of the stapes to compensate small movements of the tympanic membrane.
mXACT Partial Prothesis
Thanks to the round, bell-shaped coupling structure, the mXACT Partial Prosthesis sits securely on the head of the stapes. 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 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.
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.
Total Prostheses
Our total prostheses act as a complete replacement for the ossicular chain when only the stapes footplate is present. Choose between the mARC, mGRIP, and mXACT PRO Total Prostheses as well as the mXACT Total Prosthesis Offcenter and the mXACT Total Prosthesis Center depending on your personal preferences and your patient’s anatomy.

mARC Total Prosthesis
The mARC Total Prosthesis has a unique design. The super flexible ball joint enables the headplate to adapt to the tiniest movements of the tympanic membrane. This can reduce tension in the annular ligament and the tympanic membrane, leading to better sound transmission. Additionally, thanks to the ball joint, the headplate always lies flat against the tympanic membrane, which can reduce extrusion rates and lead to better long-term hearing results. The generous recesses and the tiltable headplate provide for maximum intraoperative visibility, and the implant’s hollow stem increases adhesive forces on the stapes footplate, enabling easier placement. Note: It is mandatory to use a cartilage shoe with the mARC Total Prosthesis.
mGRIP Total Prosthesis
The headplate of the mGRIP Total Prosthesis has a unique design with two integrated spikes that can prevent the cartilage from migrating, thereby supporting long-term stability of the reconstruction. The implant’s hollow stem increases adhesive forces on the stapes footplate, enabling easier placement. And the prosthesis can be fitted to the patient’s individual anatomy thanks to the tiltable headplate and bendable shaft.
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. 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 hollow stem 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.
Stapes Prostheses
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 five different stapes implants to choose from—mWING, mAXIS, mLOOP, mFIX, and mZAM—depending on your patient’s anatomy and your personal preference.
mWING Stapes Prosthesis
mAXIS Stapes Prosthesis
mLOOP Stapes Prosthesis
mFIX Stapes Prosthesis
mZAM Stapes Prosthesis
mWING Stapes Prosthesis
The mWING Stapes Prosthesis has a relatively thin, perforated band loop and four wings. The wings make placement and crimping more stable while the perforated, slim band loop allows for a close-to-perpendicular angle to the stapes footplate.
mAXIS Stapes Prosthesis
The loop of the mAXIS Stapes Prosthesis 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.
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.
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. For extra flexibility during surgery, the shaft can be adapted to the patient’s anatomy.
mZAM Stapes Prosthesis
The extremely thin design of the mZAM Stapes Prosthesis gives you optimal visibility when placing the implant. The off-set band loop and bendable shaft allow for flexibility during surgery.
