FDA clearance means the FDA reviewed a medical device through its 510(k) process and found it "substantially equivalent" to a device already legally on the market, for a specific intended use. It is not the same as FDA approval, which is a separate and more demanding review used for most high-risk devices. For a robotic hair transplant system, clearance tells you the device can be legally marketed for its stated use. It is not a promise of results, a ranking against other methods or an endorsement of the person using it.
The ARTAS® iXi system that Bay Ridge Dermatology uses for robotic follicular unit extraction (FUE) is an FDA-cleared Class II device. Here is what that phrase means, how to check FDA records yourself, and what to ask before a procedure.
Cleared vs. approved: how the FDA reviews Class II devices
The FDA sorts medical devices into three classes based on risk:
- Class I: lowest risk. Most are exempt from premarket review.
- Class II: moderate risk. Most need a 510(k), also called a premarket notification, before they can be sold.
- Class III: highest risk. Most need premarket approval, or PMA.
In a 510(k), the manufacturer compares its device with a "predicate," a device that is already legally marketed. The FDA checks whether the new device has the same intended use and either the same technology or differences that don't raise new questions about safety and effectiveness. If it does, the FDA issues an order clearing the device for sale. The supporting data can include engineering and bench testing, software validation and, in some cases, clinical data.
PMA is what the FDA calls its most stringent device review. Approval requires enough valid scientific evidence to show the device is safe and effective for its intended use, and applications include clinical study data.
So "cleared" and "approved" are not interchangeable. They name two different processes. If you see a 510(k) device described as "approved," that wording is not accurate.
What ARTAS iXi's clearance covers, and what it does not promise
Clearance is about a device, its intended use and its labeling. It tells you that:
- the device went through FDA premarket review and may be legally marketed in the U.S. for its cleared indications
- the manufacturer remains subject to FDA rules, such as requirements for labeling and manufacturing quality
Clearance does not tell you:
- Whether you are a candidate. That depends on your diagnosis, donor hair, health and goals.
- What your result will be. Graft growth and final density vary from person to person. Individual results vary.
- Whether robotic FUE beats manual FUE. A small 2024 randomized split-scalp study by Zhu and colleagues in the Journal of Cosmetic Dermatology found no significant difference in patient satisfaction at 12 months between robotic harvesting and manual FUE by an experienced surgeon.
- Anything about the physician. Clearance is a decision about a device. It is not a license or certification for the people who use it.
- That the procedure is risk-free. Robotic FUE is still surgery, with risks such as infection, swelling, temporary numbness and grafts that don't grow.
Reading the FDA's 510(k) records yourself
The FDA's 510(k) database is public and free to search:
- Search online for "FDA 510(k) premarket notification database" and open the FDA's search page on accessdata.fda.gov.
- Enter a device name, such as "ARTAS," or the manufacturer's name.
- Open a record to see the decision date, the decision (for example, "substantially equivalent"), the product code and the regulation number.
- Where a summary is posted, open the PDF and find the "Indications for Use" section. That is the plain statement of what the device is cleared to do, and for whom.
The database lists several clearances for the ARTAS System, beginning in 2011. Later summaries describe added uses, such as creating recipient sites (2013) and implanting harvested follicles (2018). Devices are updated over time, and an updated device may be covered by a newer record. If you want to match a clinic's system to a specific record, ask the clinic which model it uses and which clearance covers it.
The FDA also runs MAUDE, a public database of reports about medical device problems. Read it with care: the FDA cautions that these reports can be incomplete or unverified, and a single report does not show that a device caused a problem. Patients and health care professionals can report a suspected device problem through the FDA's MedWatch program.
Why candidacy matters: the cleared indication is narrower than everyone with hair loss
The Indications for Use in the posted ARTAS System summaries describe harvesting hair follicles from the scalp in men diagnosed with male pattern hair loss (androgenic alopecia) who have black or brown straight hair.
That description is narrower than the full range of people who look into hair restoration. Hair loss affects people of every sex, hair color and hair texture, and the AAD (American Academy of Dermatology) notes that men and women of all races can be good candidates for a hair transplant in general. The right plan depends on the type of hair loss, the donor supply, overall health and personal goals.
This is one reason candidacy is decided one person at a time. It is reasonable to ask your physician directly how your diagnosis and hair type fit the indication described in the device's records, and what your options are if they don't.
If your hair loss is sudden, patchy or comes with an itchy, scaly or painful scalp, see a dermatologist for a diagnosis before considering any procedure. Some types of hair loss need medical treatment rather than surgery.
Questions to ask your physician about device-related risk
- Which model of the system do you use, and which FDA clearance covers it?
- How do my diagnosis and hair type fit the cleared indication?
- Which steps does the device perform, and which does the medical team do by hand?
- Who controls and monitors the device during my procedure?
- What happens if the device has to be paused partway through?
- How are grafts checked for damage during extraction?
- What does recovery look like, and who do I contact with concerns?
At Bay Ridge Dermatology, Dr. Evangeline Perez, a board-certified dermatologist, directs robotic FUE with the ARTAS iXi and oversees each procedure from beginning to end. You can read more on our hair restoration page or at artasbrooklyn.com.
The hair restoration consultation is free. It is a visit to talk through your hair loss, your goals, whether you may be a candidate and any questions about the device, and there is no obligation to book a procedure. To schedule one, book online or call (347) 497-4984.
