Intended Use
The Chemo Mouthpiece is intended to be used to cool the oral mucosa to reduce the incidence and severity of chemotherapy induced oral mucositis in adult patients.
Device Description
The Chemo Mouthpiece is a device that reduces the temperature in the oral cavity to reduce the incidence and severity of oral mucositis (OM) associated with chemotherapy. The device is completely passive (e.g. there are no electrical components) and is designed to manually circulate saline solution and purified water inside a mouthpiece worn by the patient. The Chemo Mouthpiece (CMP) is designed with an inner chamber, an outer chamber, and breathing tubes. Prior to use the device is placed inside a standard freezer for a minimum of 6 hours, which freezes the water solid in the inner chamber, while the saline solution chamber in the outer chamber becomes cold but remains in liquid form. The device is then retrieved from the freezer and placed by the user in the oral cavity per the instructions for use. Cryotherapy is maintained continuously as the user squeezes the device to circulate the cold saline solution around the in the device. Breathing tubes that run throughout the length of the device facilitate breathing during device use.
More Information

Not Found

No
The device description explicitly states it is "completely passive" with "no electrical components" and relies on manual circulation of cold saline solution. There is no mention of AI, ML, or any computational processing in the device description or performance studies.

Yes
The device is intended to cool the oral mucosa to reduce the incidence and severity of chemotherapy-induced oral mucositis, which is a therapeutic purpose.

No

The device is designed to prevent or reduce the severity of a condition (oral mucositis) through cooling, not to diagnose a particular condition or disease.

No

The device description explicitly states it is a "completely passive" device with "no electrical components" and describes a physical mouthpiece that is frozen and manually squeezed to circulate cold saline. This indicates a hardware-based device, not software-only.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition.
  • Chemo Mouthpiece Function: The Chemo Mouthpiece is a physical device that is placed inside the patient's mouth to cool the oral mucosa. It does not collect, prepare, or examine any specimens from the body. Its function is a direct physical intervention (cryotherapy) to reduce the incidence and severity of oral mucositis.
  • Intended Use: The intended use clearly states it's for "cooling the oral mucosa to reduce the incidence and severity of chemotherapy induced oral mucositis." This is a therapeutic or preventative action, not a diagnostic one.
  • Device Description: The description details a passive device that uses frozen water and cold saline solution for cooling. This aligns with a physical therapy or intervention device, not an IVD.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information.

Therefore, the Chemo Mouthpiece falls under the category of a therapeutic or preventative medical device, not an In Vitro Diagnostic.

Classification:Class II

Device Description

The Chemo Mouthpiece is a device that reduces the temperature in the oral cavity to reduce the incidence and severity of oral mucositis (OM) associated with chemotherapy. The device is completely passive (e.g. there are no electrical components) and is designed to manually circulate saline solution and purified water inside a mouthpiece worn by the patient. The Chemo Mouthpiece (CMP) is designed with an inner chamber, an outer chamber, and breathing tubes. Prior to use the device is placed inside a standard freezer for a minimum of 6 hours, which freezes the water solid in the inner chamber, while the saline solution chamber in the outer chamber becomes cold but remains in liquid form. The device is then retrieved from the freezer and placed by the user in the oral cavity per the instructions for use. Cryotherapy is maintained continuously as the user squeezes the device to circulate the cold saline solution around the in the device. Breathing tubes that run throughout the length of the device facilitate breathing during device use.

Principles of Operation

The Chemo Mouthpiece device operates on the principle of conductive thermal heat exchange between the different layers of the device. The cold temperature of the device is maintained via conductive thermal exchange between the circulating saline solution in the outer chamber and the frozen water in the inner chamber. Placement of the device in the oral cavity initiates cryotherapy inducing temporary vasoconstriction reducing blood flow thereby decreasing the vascular delivery of chemotherapy agents to the oral mucosa hence preventing or reducing the incidence and severity of oral mucositis.

21 CFR 872.5590 describes an intraoral
cooling device as "a prescription use device
that is intended to cool the mouth for
patients to reduce the likelihood of oral
mucositis. The device consists of a
removable mouthpiece that cools the oral
mucosal surfaces".
Similar to the proposed predicate, Chemo
Mouthpiece can be classified under this
regulation based on the following:
It is a prescription use deviceIt is intended to cool the mouth of

mouthpiece that cools the oral

The IFUs between the two devices are
identical except for the following:
The Chemo Mouthpiece indications
includes the statement that it is an
intraoral cryotherapy device. This
statement is in line with clinical
guidelines for oral mucositis (e.g.
Multinational Association of
Supportive Cancer Care for
Management of Patients with OM |
| | Mucositis in adult patients. | mucositis in adult patients. | [MASCC]¹ and the National
Comprehensive Cancer Network
[NCCN] Task Force²) which
categorizes treatments used to cool
the oral mucosa during
chemotherapy delivery as "oral
cryotherapy". This statement was
not included in the predicate device,
however it does not change the
intended use (e.g. cooling of the
oral mucosa for reducing the
likelihood of OM) and instead
further supports it.

  • Cooral system specifies that the
    device should be used during
    chemotherapy treatments.
    However, the footprint of the
    Chemo Mouthpiece device is much
    smaller and was designed to be
    portable and easy to use by patients
    in their own homes. As such the
    Chemo Mouthpiece is intended to
    be used not only when patients are
    receiving their chemotherapy
    regimens but also at home
    following their infusion. This
    difference in the indications for use
    does not change the intended use.
  • The proposed indications for
    Chemo Mouthpiece replaces the
    term likelihood (from the predicate
    indications) with the word
    incidence. The term incidence and
    likelihood are synonymous and the
    modification does not introduce a
    new intended use. |

    Mouthpiece is a
    passive device that
    has no electrical
    circuitry or
    software/firmware
    components.
    Instead, patients
    squeeze the outer
    chamber of the
    device to circulate
    cold saline solution
    over a frozen inner
    chamber and
    throughout the
    mouthpiece that is
    placed in patient's
    mouth. | The Cooral System includes electronic
    circuitry and firmware. In contrast the
    Chemo Mouthpiece is a completely passive
    device without any electrical or
    software/firmware components. The
    Chemo Mouthpiece also has a smaller form
    factor than the predicate device which
    allows the device to be used at home
    following infusion.
    These differences in device design do not
    raise new questions of safety and
    effectiveness since both devices operate
    under the same principle of operation. The
    ability of the Chemo Mouthpiece design to
    result in sufficient cooling to reduce the
    likelihood of oral mucositis is supported by
    the results of performance testing. |
