Device Description
The soft palate elevator consists of an upper base appliance with a palatal plate from which a thin flat metal arm extends posterior end to terminate in a silicone rubber bulb that raises the center of the soft palate in order to "tent" that flexible structure to draw its distal end upward and forward away from the pharyngeal wall and to tighten the pharyngeal wall. The front end of the arm contains undercut tabs that extend out to the sides to lock into the acrylic in the palatal plate of the base appliance, and the back end of the arm contains features engineered to retain the rubber bulb. The arm is strong enough to elevate the middle of the soft palate about ¼'' when it is at rest during sleep and also flexible enough to move up and down with the natural action of the soft palate during swallowing when breathing stops anyway.

No
The device description details a purely mechanical device with no mention of software, algorithms, or data processing that would indicate AI/ML.

Yes
The device is described as treating snoring, making it a therapeutic device.

No
The device description and intended use clearly state that it is for "TREATMENT OF SNORING" by physically elevating the soft palate, rather than diagnosing a condition.

No

The device description clearly details physical components made of metal and silicone rubber, indicating it is a hardware device, not software-only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is "TREATMENT OF SNORING". This is a therapeutic purpose, not a diagnostic one. IVDs are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Description: The device is a physical appliance designed to mechanically alter the position of the soft palate. It does not involve the analysis of biological samples.
  • Lack of IVD Characteristics: The description does not mention any components or processes related to collecting, analyzing, or interpreting biological specimens (like blood, urine, tissue, etc.).

Therefore, this device falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

§ 872.5570 Intraoral devices for snoring and intraoral devices for snoring and obstructive sleep apnea.

(a)
Identification. Intraoral devices for snoring and intraoral devices for snoring and obstructive sleep apnea are devices that are worn during sleep to reduce the incidence of snoring and to treat obstructive sleep apnea. The devices are designed to increase the patency of the airway and to decrease air turbulence and airway obstruction. The classification includes palatal lifting devices, tongue retaining devices, and mandibular repositioning devices.(b)
Classification. Class II (special controls). The special control for these devices is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea; Guidance for Industry and FDA.”

DEVICE NAME: SOFT PALATE ELEVATOR

REGULATION NUMBER: 21 CFR 872.5570

REGULATORY CLASS: LRK

CLASSIFICATION: CLASS 2, SPECIAL CONTROLS

GUIDANCE DOCUMENT: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea

NARRATIVE DESCRIPTION

The soft palate elevator consists of an upper base appliance with a palatal plate from which a thin flat metal arm extends posterior end to terminate in a silicone rubber bulb that raises the center of the soft palate in order to "tent" that flexible structure to draw its distal end upward and forward away from the pharyngeal wall and to tighten the pharyngeal wall. The front end of the arm contains undercut tabs that extend out to the sides to lock into the acrylic in the palatal plate of the base appliance, and the back end of the arm contains features engineered to retain the rubber bulb. The arm is strong enough to elevate the middle of the soft palate about ¼'' when it is at rest during sleep and also flexible enough to move up and down with the natural action of the soft palate during swallowing when breathing stops anyway.

MATERIALS - medical silicone, 304 stainless steel, and dental acrylic.

BIOCOMPATIBILITY - the materials in the device have been evaluated for toxic leaching in a variety of use environments and found to be below the threshold for concern, and one final finished subject device was tested for cytotoxicity and found acceptable.

INTENDED USE - to prevent the soft palate from contributing to the airway restrictions that cause snoring.

INDICATIONS FOR USE - treatment of snoring.

RISKS – All but one of the risks listed in the guidance document, (damage to the TMJs and oral tissues, including unwanted movement of teeth), are common side effects of mandibular advancement appliances due to the large forces they apply to the teeth and the mandible. The subject device applies much weaker forces (about 2.5 N), and it distributes them between the whole base appliance and the soft palate elevator arm pushing the tissue-contacting bull up into the center of the soft palate. The risk of damage to the soft palate is mitigated by the softness of the tissue contacting material, the low force it applies, its high biocompatibility, and the easy

4

adjustability of its supporting arm. The risk of obstructing oral breathing is not affected by the device. The risk of releasing a small part that could cause choking or aspiration is mitigated by retentive features engineered into both ends of the arm, and these retentive features were bench tested to show that they can withstand more force than they will encounter in use. The risk of misuse is primarily from the patient bending the arm it excessively frequently enough to weaken the metal.

PREDICATE - is the adjustable soft palate lifter (K895189), which has the same intended use and indications for use as the subject device. Like the subject device, the predicate employs an arm that extends posteriorly from the posterior end of the palatal plate of an upper base appliance to push upward on the soft palate. Unlike the subject device, the predicate employs a much harder tissue-contacting material and much stronger forces in attempting to raise the entire soft palate. The technological differences between the two devices are presented in table form below.

TECHNOLOGICAL DIFFERENCES

Image /page/4/Picture/3 description: The image shows two dental appliances on a blue background. The appliance on the left is a pink retainer with metal wires. The appliance on the right is a clear retainer with a metal piece in the center.

materialOrthodontic acrylicSilicone rubber
Source of force on
tissue contactedTwo .055" diameter
stainless steel wiresOne .012" x .20" strip

These different technological characteristics of the subject device do not add new safety concerns. In fact, the subject device is likely safer and more effective than the predicate, because its lower forces make it more easily tolerated and safer for the tissues contacted; but the lower forces do not diminish effectiveness, because they are still sufficient to accomplish the intended goal, to raise the center of the soft palate during sleep when it is at rest. Therefore, the subject device is at least as safe and effective as the predicate.

5

TESTING - Bench testing of both subject device and predicate was accomplished by Engineering Materials Laboratory. Biocompatibility testing of a final finished subject device was performed by Nelson laboratories. Clinical testing was not performed.

BENEFIT/RISK ASSESSMENT - The potential benefit is elimination of snoring and therefore better sleep. An additional potential benefit is preventing damage to and lengthening of the soft palate, which has been demonstrated by imaging in snorers and presumed to be due to the effects of vibration on the tissues, and which can lead to obstructive sleep apnea. The potential risks involve damage to oral tissues and breakage that could cause a part to dislodge and choke the user, - the same benefits and risks produced by the predicate. The subject device was designed with engineered retentive features to reduce the risks of dislodging a part and with lower forces and a softer more biocompatible tissue-contacting surface to prevent tissue damage.

CONCLUSION - The Soft Palate Elevator is similar in intended use and technological characteristics. Based on the performance testing, the Soft Palate Elevator is shown to be substantially equivalent.
