No
The device description and performance studies focus on the physical properties and moldability of a thermoplastic material, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No.
This device provides support and stabilization during radiation therapy, but it does not directly apply or perform therapy. It's an accessory to the therapeutic process.
No
Explanation: The device is described as a thermoplastic material used for external support and stabilization during radiation therapy, not for diagnosing medical conditions.
No
The device description clearly states it is a "low temperature" Thermoplastic sold in sheets, indicating it is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "external support and stabilization of patients undergoing radiation therapy treatment." This is a physical support function, not a diagnostic test performed on samples from the human body.
- Device Description: The description details a thermoplastic material that is molded to the patient's body. This is a physical device, not a reagent, instrument, or system used for in vitro examination of specimens.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening of diseases or conditions
The device is a physical medical device used in a clinical setting for patient positioning and immobilization during radiation therapy.

Intended Use / Indications for Use

Device Description
- Klarity™ is a "low temperature" Thermoplastic, which is pliant and moldable by hand when heated to a temperature of 155° F. (68° C.). Heating is best done by immersion in hot water.
- Klarity™ Thermoplastic is to be sold in sheets of thickness from 1.6mm to 3.2mm, in a variety of dimensions chosen to be compatible with similar devices already in use.
- A common application of Klarity™ Thermoplastic will be as a "head mask", where perforated thermoplastic is shaped around a patient's head and then firmly attached to a support board to hold the patient's head in a fixed position for repeat radiation therapy treatments.

§ 892.5050 Medical charged-particle radiation therapy system.
(a)
Identification. A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

- · Klarity Thermoplastic is substantially equivalent to Aquaplast™ Thermoplastic, manufactured and sold by WFR Aquaplast Corporation, based in Lawlins Park, New Jersey. Aquaplast™ is registered under 510(k) Number K935067.
- · Klarity™ is a "low temperature" Thermoplastic, which is pliant and moldable by hand when heated to a temperature of 155° F. (68° C.). Heating is best done by immersion in hot water.
- · Klarity™ Thermoplastic is to be used by, or under the supervision of licensed physicians for the stabilization of patients undergoing external beam Radiation Therapy.
- Klarity™ Thermoplastic is to be sold in sheets of thickness from 1.6mm to 3.2mm, in a variety of dimensions chosen to be compatible with similar devices already in use.
- · A common application of Klarity™ Thermoplastic will be as a "head mask", where perforated thermoplastic is shaped around a patient's head and then firmly attached to a support board to hold the patient's head in a fixed position for repeat radiation therapy treatments.

- Klarity™ is equivalent to the predicate device in its chemical composition, method of manufacture, physical appearance, physical characteristics and intended use. The equivalence is verified by knowledge of the chemistry of the predicate device and physical testing. Physical testing includes detailed measurements of mass density, transmission of radiation. bolus effect, and comparison of moldability and shrinkage on simulated patient (wooden dummy).
- · Use of "low-temperature" thermoplastics is commonly taught to all licensed U.S. Radiation Therapists. and these materials are in common use at Radiation Oncology clinics throughout the U.S. and the world.
- Safety, utility and medical effectiveness of these materials is affirmed by successful use of predicate device since 1982 for radiation therapy patient stabilization.
