WARNING LETTER
CMS: 593692
December 12, 2019
Dear Mr. Herbert:
During an inspection of your firm located in Dallas, Texas from August 22, 2019 to September 5, 2019, an investigator from the United States Food and Drug Administration (FDA) determined that your firm manufactures the Curewave Medicore. Under section 201(h) of the Federal Food, Drug, and Cosmetic Act (the Act), 21 U.S.C. § 321(h), these products are devices because they are intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or to affect the structure or function of the body.
Our inspection revealed that the Curewave Medicore device is adulterated under section 501(f)(1)(B) of the Act, 21 U.S.C. § 351(f)(1)(B), because your firm does not have an approved application for premarket approval (PMA) in effect pursuant to section 515(a) of the Act, 21 U.S.C. § 360e(a), or an approved application for an investigational device exemption under section 520(g) of the Act, 21 U.S.C. § 360j(g). The device is also misbranded under section 502(o) the Act, 21 U.S.C. § 352(o), because your firm did not notify the agency of its intent to introduce the device into commercial distribution, as required by section 510(k) of the Act, 21 U.S.C. § 360(k).
On May 18, 2017, your firm submitted a premarket notification, K171343, for the CureWave System, the CureWave Laser, and the CureWave Medicore. In a letter dated July 14, 2017, FDA advised you that the agency had determined the final classification of these devices to be Class II Exempt, under 21 CFR 890.5500, with a product code of ILY. This letter also stated that if you were to modify your device in the future by introducing either a new indication for use or a fundamental scientific technology different from that in the regulation, your device might exceed the limitations to the exemption and could consequently require 510(k) clearance prior to marketing this device in the United States. Devices under the ILY product code are intended to provide topical heating to the treatment area. However, evidence collected during our inspection demonstrates that your firm is marketing these devices with intended uses of “tissue regeneration”, “healing” and “improved vascular and cellular structural integrity.”
Additionally, a review of your firm’s websites (https://www.curewavelasers.com/, http://www.curewavelasers.com/doctors/, and http://www.curewavelasers.com/patients/) shows that you are marketing these devices with the following claims:
• The CureWave Laser is a proven and effective option for any person who prefers an effective alternative to drugs and borderline surgeries.
• The CureWave Laser technology is an advanced cutting edge technology revolutionizing the treatments for all soft tissue issues... and conditions as well as wound care.
• The major effects of the CureWaves Laser System include:
o Enhanced Nerve Function
o Quicker Wound Healing
o Fights Bacterial Infection
o Increase of Metabolic Activity
• CureWave Laser has successfully treated the following conditions demonstrating the lasers safety and efficacy:
o Adhesive capsulitis (frozen shoulder)
o Ankylosing spondylitis
o Bactericidal effects
o Buerger’s disease (thromboangiitis obliterans)
o Cervical spine Cranial nerve VII (facial nerve) repair
o Dental hypersensitivity
o Diabetic neuropathy
o Diabetic ulcers
o Following dental surgery
o Following neurosurgery
o Hemangioma
o Keloids
o Nerve repair
None of these uses is included within the scope of the exemption from 510(k) notification for the above-referenced regulation.
Your firm has provided no evidence to FDA supporting the safety and efficacy of the CureWave laser devices as marketed on the websites listed above. The lack of evidence demonstrating the safety and efficacy of these claims raises public health concerns. Specifically, the risk for these devices, as advertised, is delay in definitive treatment. For example, delayed or ineffective treatment for wound care and bacterial infection can lead to loss of function, amputation, or death. Additionally, delayed or ineffective treatment for nerve damage can lead to permanent loss of function.
For a device requiring premarket approval, the notification required by section 510(k) is deemed satisfied when a PMA is pending before the agency, per 21 CFR 807.81(b). The kind of information that your firm needs to submit in order to obtain approval or clearance for the device is described on the Internet at:
http://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/HowtoMarketYourDevice/default.htm
.
The FDA will evaluate the information that your firm submits and decide whether the product may be legally marketed.
Our inspection also revealed that these devices are adulterated within the meaning of section 501(h) of the Act, 21 U.S.C. § 351(h), in that the methods used in, or the facilities or controls used for, their manufacture, packing, storage, or installation are not in conformity with the current good manufacturing practice requirements of the Quality System regulation found at Title 21, Code of Federal Regulations (CFR), Part 820. These violations include, but are not limited to, the following:
1. Failure to establish and maintain procedures to control the design of the device in order to ensure that specified design requirements are met, as required by 21 CFR 820.30(a).
Specifically, your firm has not established design control procedures. Your firm has not implemented your undated “Design & Development” procedure, DES/0100, revision 0. For example;
a. Section 4.0-4.1.3 of your procedure states design inputs consist of identification and documentation of the requirements of the device under design. Form DES/0100-3: Design Input Checklist is to be used as an aid in assuring that no aspect of design input is overlooked. Form DES0100-4: Design Input Details is to be used to document design input specifications. Your firm did not document design inputs for the Curewave Medicore.
b. Section 5.0-5.1.5 of your procedure states design outputs are to be documented on Form DES/0100- 4: Design Input Details and used to document that specifications have been met. The procedure goes on to state that the project manager will review and approve the design documentation through each design phase and at regularly scheduled design review meetings will assure the update of the design history file. Your firm did not identify/ document design outputs for the Curewave Medicore.
c. Section 7.0 - 7.1.6 of your procedure states verification activities and tasks are completed throughout the design process. These activities are review, analysis, test, inspections, etc. and are listed in the DES/0100-4: Design Input Details. Your procedure goes on to state the design verification records will include a description of the methods (material, test, equipments, etc.) used, the results, the name(s) of the individual(s) completing the verification, and the date, recorded on form DES/0100-8: Design Verification Summary. Your firm performed various design activities including: an external skin temperature test using the Curewave Laser, skin test, laser fiber checks, etc. These design verification activities were not performed nor documented as per the design verification section 7.1.6.
• The “External skin temperatures using the curewave laser test”, dated June 21, 2016 indicates that safety tests for external skin temperatures using the CureWave laser at 30, 60, and 90 seconds were performed. The design verification activities do not include a protocol on how the test was performed, what equipment (including serial number) was used, or the name of the individual performing the test. The verification activities also do not establish an acceptance criteria prior to performing the test, nor does it interpret how the results of the tests were acceptable.
• The “Patient Skin Temperature with Various CW Treatment Areas and Patients” test indicates that skin temperatures were measured using a laser temperature reader. The test shows that the verification test was performed on 2 patients at various power settings for 60 seconds. The design verification activities do not include a protocol on how the test was performed, what equipment (including serial number) was used, or the name of the individual performing the test. The verification activities also do not establish an acceptance criteria prior to performing the test, nor does it interpret how the results of the tests were acceptable.
2. Failure to establish and maintain procedures for acceptance of incoming product, as required by 21 CFR 820.80(b).
Specifically, your firm has not established procedures for acceptance activities for your incoming components or finished products. For example,
You stated you conduct various power related tests using a fiber scope, power meter, and stopwatch on your subassemblies received from your contract manufacturer. However, you stated you do not have a written procedure describing these activities. Additionally, you stated you do not maintain records of the results of these activities, as required by 21 CFR 820.80(e).
3. Failure to establish and maintain procedures to ensure that all purchased or otherwise received product and services conform to specified requirements, as required by 21 CFR 820.50. For example,
a. Your firm has not implemented your undated “General Purchasing” procedure, PUR/0100, Rev. 0. For example, section 2.4 of your procedure states you will evaluate your suppliers yearly. However, you have not documented any evaluation of your laser diode and subassembly suppliers.
b. Your firm has not implemented your undated “Vendor Assessment Procedure’, PUR/0200, Rev: 0. Your procedure states each vendor will be assessed in 3 areas on an annual basis and an assessment will be completed. However, your firm has not completed vendor assessments on your suppliers, contractors, and consultants.
c. Your firm has not established agreements with your suppliers requiring them to notify you of changes to your purchased products and components which may affect the quality of your finished devices.
4. Failure to establish and maintain procedures to ensure that device history records (DHR’s) for each batch, lot, or unit are maintained to demonstrate that the device is manufactured in accordance with the device master record (DMR) and the requirements of this part, as required by 21 CFR 820.184.
Specifically, your firm has not established procedures for maintaining DHR’s for each batch, lot, or unit of products showing compliance with your device master record. Your firm has distributed 49 Curewave Medicore devices. You have not maintained DHRs for these devices which contain the date of manufacture, acceptance records, or primary identification labels.
In addition to being a “device”, the Curewave Medicore laser systems are “electronic products” subject to compliance with Subchapter C of the Act, Electronic Product Radiation Control, the requirements at 21 CFR 1000-1005, and the performance standards at 21 CFR 1010, 1040.10, and 1040.11. Your firm failed to comply with the regulations regarding certification, product safety, reports, and recordkeeping.
5. Failure to certify, based on a test, in accordance with the standard, of the individual article to which the electronic product is attached, or upon a testing program which is in accordance with good manufacturing practices, as required by 21 CFR 1010.2(c). Specifically, your firm has not conducted a certification of its Class IV laser product based upon a test, in accordance with the standard, or testing program which is in accordance with good manufacturing practices. During the inspection, your firm acknowledged that it has not performed any tests (internally or externally) to certify the device as a Class IV laser.
6. Failure to incorporate in each Class IV medical laser product a means for the measurement of the level of that laser radiation intended for irradiation of the human body, having an error in measurement of no more than 20% when calibrated, as required by 21 CFR 1040.11(a)(1). Specifically, your firm manufactured and distributed a Class IV laser that emits 44 W at a wavelength of 1280 nm. Your firm did not incorporate a means for measuring the level of radiation in the laser product.
7. Failure to affix to each medical laser product, in close proximity to each aperture through which is emitted accessible laser radiation in excess of the accessible emission limits of Class I, a label bearing the wording: “Laser aperture”, as required by 21 CFR 1040.11(a)(3). Specifically, your firm manufactured and distributed laser products that did not have the “Laser aperture” label affixed.
8. Failure to provide the full name and address of the manufacturer of the product in a label, as required by 21 CFR 1010.3(a). The label shall be permanently affixed or inscribed on the product so as to be legible and readily accessible to view when the product is fully assembled for use. However, your firm has manufactured and distributed laser products and the following information was missing from the labels:
• Complete address of firm
• Month and year the device was manufactured
A review of your firm’s identification label revealed it contained only your firm’s name, city/state, website and sequential number.
9. Failure to submit a product report to the FDA/CDRH, prior to the introduction of a laser product into commerce, as required by 21 CFR 1002.10. For example, Curewave Lasers has manufactured and distributed 49 laser devices since 2017. However, FDA has not received initial product reports for these electronic products. FDA has also not received the subsequent annual reports, which are also required under 21 CFR 1002.13.
Section 538(a) of the Act, Subchapter C Electronic Product Radiation Control (EPRC), 21 U.S.C. § 360oo(a), prohibits any manufacturer from certifying or introducing into commerce electronic products which do not comply with an applicable standard. This section also prohibits any person from failing or refusing to establish and maintain required records or from failing to submit required notifications, reports, material, or information. Failure to respond to this letter may be considered to be a violation of section 538(a)(4) of the Act, 21 U.S.C. 360oo(a)(4). FDA is prepared to invoke regulatory actions if you fail to comply with these requirements. These actions may include an injunction and/or imposition of civil penalties as provided for in section 539 of the Act, 21 U.S.C. § 360pp. Persons who violate section 538 of the Act are subject to civil penalties of up to $1,100 per violation and up to a maximum penalty of $375,000 without further notification by the FDA.
As it pertains to the EPRC failures to comply, you are required, under 21 CFR 1003.11(b), to immediately provide a written response to FDA with the number of referenced products which have been produced and the number of such products that have left the place of manufacture.
