Intended Use
Temporary implant for ventilation and drainage of middle ear. Temporary implant for ventilation or drainage of the middle ear.
Device Description
The umbrella-type implant comes mounted on a tiny single-use trocar point. Its penetrating edge penetrates the tympanic membrane and simultaneously forms a passage to draw the ventilation tube into that passage at a controlled rate until the ventilation tube is implanted. The trocar is immediately withdrawn. The procedure requires the use of a specially designed trocar handle. The tubes are available with or without retention wires.

Not Found

No
The device description and other sections do not mention AI, ML, or any related concepts. The device is a simple mechanical implant.

Yes
The device is a temporary implant for ventilation or drainage of the middle ear, directly impacting bodily function by facilitating airflow and fluid removal.

No
The device is described as an "implant for ventilation and drainage of middle ear," which suggests a therapeutic or interventional function rather than a diagnostic one. It facilitates a physiological process (ventilation/drainage) rather than identifying or characterizing a disease or condition.

No

The device description clearly describes a physical implant (umbrella-type implant) and associated hardware (trocar point, trocar handle). It is not solely software.

Based on the provided information, 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. They are used outside of the body (in vitro).
  • Device Function: The described device is a temporary implant designed to be placed inside the middle ear for ventilation and drainage. It is a surgical device used in vivo (within the body).
  • Intended Use: The intended use clearly states "Temporary implant for ventilation and drainage of middle ear," which is a therapeutic and surgical purpose, not a diagnostic test performed on a sample.

Therefore, this device falls under the category of a surgical implant or medical device used for treatment, not an in vitro diagnostic.

§ 874.3880 Tympanostomy tube.

(a)
Identification. A tympanostomy tube is a device that is intended to be implanted for ventilation or drainage of the middle ear. The device is inserted through the tympanic membrane to permit a free exchange of air between the outer ear and middle ear. A type of tympanostomy tube known as the malleous clip tube attaches to the malleous to provide middle ear ventilation. The device is made of materials such as polytetrafluoroethylene, polyethylene, silicon elastomer, or porous polyethylene.(b)
Classification. Class II.

2.8 Device Description: [807.92(a)(4)+(6)]

The umbrella-type implant comes mounted on a tiny single-use trocar point. Its penetrating edge penetrates the tympanic membrane and simultaneously forms a passage to draw the ventilation tube into that passage at a controlled rate until the ventilation tube is implanted. The trocar is immediately withdrawn. The procedure requires the use of a specially designed trocar handle.

The tubes are available with or without retention wires.

2.9 Reasons for Device Modification: [807.92 (d)]

  • Elimination of need for prior paracentesis. Simultaenous 1. incision of tympanic membrane and implant insertion
    1. Considerably shorter procedure
    1. Secure placement due to precise cut
  • Reduced incrustation susceptibility due to clean and 4. precise cut
    1. Minimal trauma as considerably less invasive than traditional VT placement

2.10 Industry Standards: [807.92 (d)]

KURZ certifies compliance with all appropriate industry standards and the validation of methods and processes covered by these standards.

2.11 MRI Environment: [807.92 (d)]

Testing in a 7.0 Tesla nuclear magnetic resonance (NMR) tomograph has revealed no implant movement and no adverse tissue effects attributable to MRI-generated heating.

2.12 Information Bearing on the Safety and Effectiveness:

(807.92 (b)(3)]

The ventilation tube is provided in gilded silver or pure titanium. Both materials have a long history of safe and effective use. The trocar point and handle are manufactured of stainless surgical steel. The trocar point projects just enough to penetrate the membrane and to create the opening for positioning the ventilation tube. The precise cut and secure placement of the implant should reduce the risk of premature extrusion or

dislocation. The umbrella design of the ventilation tube comparable to many others on the market - introduces no new risks. There are no additional characteristics known that should adversely affect the safety and effectiveness of these implants.

The results of design valldation raise no new issues of safety and effectiveness.

Dear Ms. Maeser:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a dctermination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
