Intended Use
The Resolve™ UVB Phototherapy System is an ultraviolet light emitting medical device indicated for phototherapeutic treatment of dermatologic conditions such as psoriasis, vitiligo, atopic dermatitis (eczema), and seborrheic dermatitis. The Allux Medical Resolve™ UVB Phototherapy System is intended to be used with all Skin Types (I - VI).
Device Description
The Resolve™ UVB Phototherapy System is designed to deliver therapeutic ultraviolet-B light to a localized area onto a patient's skin surface. This system is designed to be easy to operate and is intended to be used in an outpatient setting such as a dermatologist's office under supervision of trained medical personnel. The device is comprised of two distinct components. The first is a patient attached unit and the second is a medical grade power supply. The patient attached unit is small and lightweight and is intended to be held in place or affixed to a patient at the desired treatment site. A portion of one side of the patient attached unit is composed of a fused silica transparent window out of which ultraviolet light is emitted; this window surface is intended to make contact with and lay flush to the skin thus enabling a localized treatment. The patient attached unit houses an array of ultraviolet light emitting diodes (UV-LEDs) that serve as the therapeutic light source. Additionally, the drive and control circuitry necessary to operate the UV-LEDs, as well as a fan and heat sink to dissipate waste thermal energy, are located inside the patient attached unit's protective housing. Operator interface features include on-off switch and both visual and audible status indicators.

Yes
The device is indicated for "phototherapeutic treatment of dermatologic conditions" and is designed to "deliver therapeutic ultraviolet-B light," which directly implies its purpose is to provide therapy.

No
The device description and intended use state it is for "phototherapeutic treatment" and "deliver therapeutic ultraviolet-B light," indicating a treatment function, not a diagnostic one.

No

The device description explicitly states it is comprised of two distinct hardware components: a patient attached unit and a medical grade power supply. It details the physical components within the patient attached unit, including UV-LEDs, circuitry, a fan, and a heat sink.

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.
  • Device Function: The Resolve™ UVB Phototherapy System is a medical device that delivers ultraviolet light directly to the patient's skin for therapeutic treatment of dermatologic conditions. It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states "phototherapeutic treatment of dermatologic conditions," which is a direct treatment method, not a diagnostic test.
  • Device Description: The description focuses on the physical components and how it delivers light to the skin surface. There is no mention of sample collection, analysis, or diagnostic results.

Therefore, the Resolve™ UVB Phototherapy System falls under the category of a therapeutic medical device, not an in vitro diagnostic device.

510(K) S OF SAFETY AND EFFECTIVENESS SECTION 5.

The device is comprised of two distinct components. The first is a patient attached unit and the second is a medical grade power supply. The patient attached unit is small and lightweight and is intended to be held in place or affixed to a patient at the desired treatment site. A portion of one side of the patient attached unit is composed of a fused silica transparent window out of which ultraviolet light is emitted; this window surface is intended to make contact with and lay flush to the skin thus enabling a localized treatment.

The patient attached unit houses an array of ultraviolet light emitting diodes (UV-LEDs) that serve as the therapeutic light source. Additionally, the drive and control circuitry necessary to operate the UV-LEDs, as well as a fan and heat sink to dissipate waste thermal energy, are located inside the patient attached unit's protective housing. Operator interface features include on-off switch and both visual and audible status indicators.

Indications for Use:

The Resolve™ UVB Phototherapy System is an ultraviolet light emitting medical device indicated for phototherapeutic treatment of dermatologic conditions such as psoriasis, vitiligo, atopic dermatitis (eczema), and seborrheic dermatitis. The Allux Medical Resolve™ UVB Phototherapy System is intended to be used with all Skin Types (I - VI).

Description of Substantial Equivalence:

Currently published clinical data support UVB phototherapy treatment for a variety of dermatologic conditions. The intended use of the Resolve UVB Phototherapy System is considered by Allux Medical to be within the scope of the predicate devices that emit UVB light for dermatologic phototherapy. The Resolve UVB Phototherapy System employs light emitting diodes (LEDs) as a light source. This technological feature is not considered by Allux Medical to raise new questions of safety or efficacy. Use of LEDs as a therapeutic light source in medical devices is within the scope of predicate devices that are used in phototherapeutic applications such as the treatment of neonatal hyperbilirubinemia.

Performance Data:

The Resolve UVB Phototherapy System has the same indications for use as those cleared for the claimed UVB predicate devices. Performance data are included with the 510(k) to demonstrate that UVB emissions are within specification for the device and are the same or very similar to the spectra emitted by the predicate UVB devices. Additionally, information to support electrical safety, electromagnetic compatibility, biocompatibility, and functionality were included with the 510(k).

SECTION 5. 510(K) SUMMARY OF SAFETY AND EFFECTIVENESS

Conclusion:

The Resolve UVB Phototherapy System is similar to other UVB emitting devices for localized treatment of dermatologic disease with the main difference being the source of the UV light. The Resolve device uses LEDs as a UVB light source. LEDs are used in other medical devices to provide light at spectra other than UVB. Since the Resolve UVB System has the same intended use, employs similar technologies, and is judged to pose no new questions of safety and effectiveness when compared with devices that have been cleared, Allux Medical considers it to be substantially equivalent to the legally marketed claimed predicate devices for the purpose of this 510(k) submission.
