No
The device description explicitly states the system consists of a sterile, single-use, disposable kit and an electromechanical, non-sterile, 50-use motor module, indicating it includes hardware components.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "long term improvement in the appearance of cellulite in the buttocks and thigh areas of adult females." This is a cosmetic/aesthetic procedure performed directly on the patient's body.
- Device Description: The device description details a system for "precise focal release of subcutaneous tissue." This is a physical intervention on the body.
- Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, tissue) taken from the body to provide information about a person's health or condition. This device does not involve the analysis of any biological samples.
The information provided clearly describes a device used for a surgical or aesthetic procedure performed directly on the patient, not for in vitro diagnostic testing.

- Device Description: The Cellfina System is intended to provide precise focal release of subcutaneous tissue for improvement in the appearance of cellulite. The system consists of a sterile, single-use, disposable kit (CK1) and an electromechanical, non-sterile, 50-use motor module (CM1).
- Indications for Use: The Cellfina System is intended for long term improvement in the appearance of cellulite in the buttocks and thigh areas of adult females as supported by clinical data demonstrating no significant reduction in treatment benefits up to 3 year of observation.
Substantial Equivalence Comparison:
The subject device and the predicate device are similar in the following ways: same regulation number and product code, anatomical use area, clinical use group (doctor's office, clinic), energy type with the same mechanism of action, packaging materials and configuration are unchanged, there are no differences in patient contacting materials, design of the CK1 Disposable Kit is the same, and the sterilization SAL is the same (EO, SAL 10th. Both devices are compliant to IEC 60601 standards and EMC standards.
The subject device differs from the predicate device in that the subject device is intended for 3 year efficacy whereas the predicate is intended for 2 year efficacy. In addition, the subject device's CK1 Disposable Kit has a shelf life of 24 months, whereas the predicate device had a shelf life of 12 months. The subject device CK1 is now qualified for a fully validated sterilization cycle, whereas the predicate went through a sterilization batch release process. The Subject Motor Module is intended for use up to 50 uses, whereas the predicate was intended for use up to 15 uses. The subject Motor Module is now validated for two types of cleaning methods (IPA based wipes and Chloride based wipes). The housing material for the enclosure and power button also changed from ABS and Elastomer to Makroblend and Wacker Elastosil, respectively in order to include a more robust material type that would withstand the new cleaning method. These are non-patient contacting materials and therefore additional biocompatibility testing was not necessary. The predicate device was only validated for one type of cleaning (Chloride based wipes). The subject device Motor Module includes minor tolerance changes to allow for injection molding, whereas the predicate was machined. Minor changes to location of epoxy, simplification of design to remove metal pin and using screws instead of heat staking were made to accommodate a 50 use "use life". The subject device will have a separate IFU for the CK1 and CM1, whereas the predicate utilized identical IFUs with repetitive information.
Non-clinical Performance Data:
Bench testing was performed to verify that the modifications to the subject device do not impact the safety or effectiveness of the device. Retesting for EMC and IEC 60601 was completed for the motor module to ensure that the changes in design would have no impact on safety or efficacy. Shelf life testing and use life testing were conducted on the CK1 and CM1 respectively for the changes in shelf and use life, which demonstrated full functionality. Cleaning and disinfection testing was conducted for the addition of the cleaning method for the motor module

with no impact to device performance. Sterilization was completed for the CK1 disposable kit in order to remove the requirement for batch release testing. The SAL level and sterilization method (EO) remains the same.
Clinical Performance Data (In-Vivo):
The safety and effectiveness of the Cellfina System was evaluated in a pivotal clinical study conducted under IDE G120116. The IDE was modified to allow for extended follow-up clinical performance data to be gathered for safety and efficacy at 3 years. No additional treatments were performed.
During the course of the 3 year Clinical study, 10 of the 55 subjects were lost to follow up. The reason for loss to follow up ranged from inability to contact the subject after multiple attempts to the subject removing herself from the study. Imputation analyses were performed for the 10 missing subjects from the 3 year report and carried out using the last observation carried forward (LOCF) for both the primary and 1st secondary endpoints using a paired t-test as well as multiple imputation for the primary effectiveness endpoint only, which met the study endpoint. The overall study success was met, despite the reduction in follow up participation at 3 years with a clinically significant, long term improvement in the appearance of cellulite in the treated subjects. The table below is based on the LOCF data and accounts for the 10 missing subjects:

There were no subjects who reported pain at the 3 year follow-up. |
Conclusion:
This Traditional 510(k) Premarket Notification is for an expansion to the indications for use (from 2 years to 3 years). Additionally, the motor module (CM1) use life has been extended from 15 uses to 50 uses and the shelf life of the disposable kit (CK1) has been extended from a 12 month shelf life to a 24 month shelf life. Labeling changes have also been implemented to reflect the above described changes. Additional testing was performed for compliance to Amendment 1:2012 (Edition 3.1) of 60601-1 and EMC 60601-1-2:2007 3rd Edition.
These changes do not pose any new questions of safety, product output or efficacy. As demonstrated through bench testing and clinical data, the subject device Cellfina System is as safe, as effective, and performs as well as the legally marketed predicate device (K153677), and as such, is substantially equivalent.
