Intended Use

The FreeStyle Freedom Lite Blood Glucose Monitoring System is intended for single-patient use.

Device Story

System uses coulometric biosensor technology to measure glucose in fresh capillary whole blood (finger, palm, upper arm). User inserts test strip into meter; meter performs display check; user applies blood sample to strip. Meter detects trigger current when electrodes are covered; performs electrochemical assay using Glucose Dehydrogenase (GDH) enzyme. Electrons transferred via co-factor/mediator generate electrical current; current integrated over time to calculate glucose concentration. Output displayed on screen. Used by patients at home for diabetes management. Modification adds validated cleaning/disinfection protocols using Clorox Healthcare Bleach Germicidal Wipes to support multi-year use.

Clinical Evidence

Bench testing only. Performance studies demonstrated that the modified system maintains safety and effectiveness equivalent to the predicate device, specifically validating the device's integrity through 522 cleaning/disinfection cycles for the meter and 210 cycles for the lancing device.

Technological Characteristics

Coulometric biosensor; GDH-FAD enzyme; electrochemical measurement. Dimensions/form factor: handheld meter with strip port, display, and buttons. Power: 3V CR2032 lithium battery. Connectivity: USB cable. Cleaning/disinfection: validated for Clorox Healthcare Bleach Germicidal Wipes (EPA Reg. #67619-12).

Indications for Use

Indicated for single-patient use for blood glucose monitoring.

Regulatory Classification

Identification

A glucose test system is a device intended to measure glucose quantitatively in blood and other body fluids. Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus, neonatal hypoglycemia, and idiopathic hypoglycemia, and of pancreatic islet cell carcinoma.

Special Controls

*Classification.* Class II (special controls). The device, when it is solely intended for use as a drink to test glucose tolerance, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.

Predicate Devices

• FreeStyle Lite Blood Glucose Test Strips (K092602)

SPECIAL 510(k): Device Modification OIR Review Summary

To: THE FILE

RE: DOCUMENT NUMBER K150531

This 510(k) submission contains information/data on modifications made to the SUBMITTER'S own Class II, Class III or Class I devices requiring 510(k). The following items are present and acceptable (delete/add items as necessary):

1. The name and 510(k) number of the SUBMITTER'S previously cleared device. (For a preamendments device, a statement to this effect has been provided.) k092602, FreeStyle Freedom Lite Blood Glucose Monitoring System.
2. Submitter's statement that the INDICATION/INTENDED USE of the modified device as described in its labeling HAS NOT CHANGED along with the proposed labeling which includes instructions for use, package labeling, and, if available, advertisements or promotional materials (labeling changes are permitted as long as they do not affect the intended use).
3. A description of the device MODIFICATION(S), including clearly labeled diagrams, engineering drawings, photographs, user's and/or service manuals in sufficient detail to demonstrate that the FUNDAMENTAL SCIENTIFIC TECHNOLOGY of the modified device has not changed.

This change was for: Incorporate validated cleaning and disinfection procedures into the labeling of the FreeStyle Freedom Lite Blood Glucose Monitoring System.

4. Comparison Information (similarities and differences) to applicant's legally marketed predicate device including, labeling, intended use, physical characteristics. Studies performed include disinfection efficacy study to show viral elimination effectiveness and meter robustness studies.
5. A Design Control Activities Summary which includes:

a) Identification of Risk Analysis method(s) used to assess the impact of the modification on the device and its components, and the results of the analysis
b) Based on the Risk Analysis, an identification of the verification and/or validation activities required, including methods or tests used and acceptance criteria to be applied

The labeling for this modified subject device has been reviewed to verify that the indication/intended use for the device is unaffected by the modification. In addition, the submitter's description of the particular modification(s) and the comparative information between the modified and unmodified devices demonstrate that the fundamental scientific technology has not changed. The submitter has provided the design control information as specified in The New 510(k) Paradigm and on this basis, I recommend the device be determined substantially equivalent to the previously cleared (or their preamendment) device.

The FreeStyle Freedom Lite Blood Glucose Monitoring System is intended for single-patient use. Disinfection efficacy of the Clorox Healthcare Bleach Germicidal Wipes (EPA #67619-12) was validated using materials from the meters demonstrating complete inactivation of duck hepatitis B virus (HBV). The sponsor also performed robustness studies demonstrating that there was no change in performance or in the materials of the FreeStyle Lite Blood Glucose Meter after 1044 cleaning and 1044 disinfection cycles (4 cycles per week for 5 years) designed to simulate five years use life of the device. However, the sponsor has provided a risk management report which includes a risk analysis for 522 cleaning and 522 disinfection cycles to claim 2 cleaning and disinfection cycles for a 5 years use life of the device in the labeling. The labeling was reviewed for adequate instructions for the validated cleaning and disinfection procedures.
