(90 days)
No
The device description details a system with potentiometers and a tone switch for manual adjustments, and there is no mention of AI or ML in the document.
Yes
The device is described as a hearing aid system (BAHA™ Cordelle II System) intended to treat conductive and mixed hearing loss by providing sound amplification, which directly addresses a medical condition.
No
Explanation: The device is a bone-anchored hearing aid designed for sound amplification to treat conductive or mixed hearing loss, not to diagnose a medical condition.
No
The device description clearly outlines multiple hardware components including a titanium fixture, abutment, sound processor, and body worn unit.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that this device is a Bone-Anchored Hearing Aid (BAHA™) system. Its function is to transmit sound vibrations directly to the temporal bone to improve hearing in individuals with specific types of hearing loss.
- Mechanism of Action: The device works by physically anchoring a sound processor to the skull bone, bypassing the outer and middle ear. This is a mechanical and auditory function, not a diagnostic test performed on a biological sample.
- Intended Use: The intended use is to provide sound amplification for patients with conductive or mixed hearing loss who cannot use conventional air conduction hearing aids. This is a therapeutic and assistive function, not a diagnostic one.
The device description, intended use, and anatomical site all point to a hearing aid system, which falls under the category of medical devices, but not specifically in vitro diagnostics.
N/A
Intended Use / Indications for Use
The Branemark Bone-Anchored Hearing Aid (BAHA™) Cordelle II System is intended to be used as a bone-anchored, bone-conduction hearing aid. The device is indicated for use in patients who have conductive hearing loss and can still benefit from sound amplification. Also indicated are patients with mixed hearing loss with average bone conduction thresholds in the indicated ear better than 45dB HL. The nominal output from the BAHA Cordelle II is on average 13 dB stronger than the Classic 300 (measured at 0.5, 1,2,3 kHz). The Cordelle II is recommended for patients having the same indications for the Classic 300 but where slightly stronger amplification is needed than what is delivered by the Classic 300 model. (Patients with bone conduction thresholds better than 45dB HL will be expected to improve, but may not achieve levels in the normal range. Patients with a bone conduction threshold where each standard measured frequency threshold is less than 25 dB HL can be expected to have restored hearing levels in the normal range.) The patients indicated for this device must also be unable to use conventional air conduction hearing aids or undergo ossicular replacement surgery because of one of the following:
- Chronic otitis media (COM); or
- Congenital malformation (CM) of the middle/external ear; or
- Other acquired malfunctions of the middle or external ear canals which preclude the wearing of a conventional air conduction hearing aid.
Additional indications to be met by perspective BAHA™Cordelle II candidates:
- Patients (either by themselves or with the aid of others) must be able to maintain the abutment/skin interface of the BAHA. Therefore, careful consideration must be given as to the patient's psychological, physical, emotional and developmental capabilities to maintain hygiene. In the case of children part, but not all, of that responsibility falls on the parent or guardian.
- For children and patients with congenital malformation, sufficient bone volume and bone quality must be present for a successful fixture implantation. Alternative treatment such as conventional bone conduction hearing aids, should be considered for patients having a disease state that might jeopardize osseointegration.

Device Description
The Braneniark Bone-Anchored Hearing Aid (BAHA™) Cordelle II System includes a titanium fixture which is placed in the temporal bone just behind the ear, an abutment, vanous accessories necessary for the placement and use of the fixture/abutment pillar, a sound processor which is attached to the abutment and a body worn unit which has two potentiometers that control threshold knee and loundness boost and a tone control switch.
Transducer
The transducer is an at-the-ear level sound processor which uses a direct connection to the skull bone without intervening skin and soft tissue. The transducer is attached to a snap coupling titanium abutment, which is fastened to a titanium flange fixture using a gold screw. The transducer is connected to a body worn unit via a cord with electrical output and input connectors.
Body Worn Unit
As noted previously the body worn unit has two potentiometers which control the threshold knee and loudness boost. The unit is also equipped with an electrical input to receive signals from a "Walkman" FM/IR system. When the electrical contact is connected it overrides the telecoil signal.
The body worn unit has a tone switch which controls the frequency response. The switch can be set in three different positions. N= Normal, which gives the widest frequency response. H= High frequency emphasis (reduction of low frequency sounds). L= Low frequency emphasis (reduction of high frequency sounds). The tone switch is effective for all inputs (microphone, telecoil, electrical).
The two trim controls marked LB and TK can be adjusted with a small screwdriver by the patient's audiologist. The LB adjusts the gain for loud sounds and the TK adjusts the gain for soft sounds.
The body worn unit is equipped with a clip so you can attach the unit to the patient's clothing (i.e. shirt/blouse pocket ... ).
Abutment Snap
There is an abutment snap which is mounted to the transducer. It is designed to snap into the abutment and hold the transducer securely in place.
Abutment Insert
The function of the abutment insert is to act as a guide for the abutment snap. It makes it easier to connect the transducer to the abutment. It also protects the inside of the abutment from dirt.
Abutment and Abutment Screw
The abutment is a replaceable percutancous connection between the fixture and the external sound processor which is partially or totally submerged into soft tissue. The abutment is made of titanium and is fastened to the fixture via an internal an abutment screw.
Abutment Cover
When the transducer is not in place you can attach the abutment cover on the abutment to make it look more aesthetically pleasing. One can attach the cover by pressing it into place on the abutment.
Fixture
The fixture is a threaded titanium screw which is implanted into the temporal bone and intended to provide permanent bone anchorage as a means to attach the sound processor.
Cover Screw and Healing Cap
The cover screw and healing cap are temporary components utilized only during the healing periods post surgical placement of the titanium fixture. The cover screw is used during the first healing period and is arrached to the fixture and covered with the soft tissue during the healing of the bone and soft tissue. The covers the upper part of the internal threads of the fixture. Thus, the cover screw will preclude bone and soft tissue from growing into the site where the abutment will be placed. The healing cap is used during the second healing period and covers the abutment surface. These components are used only during the healing stages of the surgery and remain in place for three to four months and one to two weeks respectively.

The Branemark Bone-Anchored Hearing Aid BAHA®™Cordelle II System is substantially equivalent to the Branemark Bone-Anchored Hearing Aid BAHA™, K955713, K984162 and to the Branemark System® Bone-Anchored Craniofacial Prosthetic Attachment System (BA-CPAS), K9445154 for the following:
-
- The BAHA Cordelle II System has the same intended use as the predicate products
-
- The BAHA Cordelle II System has the same identical technological characteristics as the predicate products
-
- The BAHA Cordelle II System has the same identical surgical technique as the predicate products
-
- The BAHA Cordelle II System has similar manufacturing processes; and same packaging and sterilization process as the predicate products
Therefore, based on the facts presented above, we believe the BAHA™ Cordelle II System is substantially equivalent to the predicate products and respectfully request the concurrence of the Agency.
