Intended Use

The ACL TOP Family 50 Series (ACL TOP 750; ACL TOP 750 CTS; ACL TOP 750 LAS; ACL TOP 550 CTS; ACL TOP 350 CTS) is intended for in vitro diagnostic use in clinical laboratories to perform coagulation and fibrinolysis testing on human citrated plasma samples.

Device Story

ACL TOP Family 50 Series: automated coagulation analyzers for clinical laboratories; process human citrated plasma samples to perform coagulation and fibrinolysis assays. Modification adds permission-based remote-control desktop sharing; enables remote delivery of software, OS patches, and test parameter updates. Device remains substantially equivalent to predicate K150877; fundamental scientific technology unchanged. System provides automated diagnostic results to clinicians for patient management.

Clinical Evidence

Bench testing only. Software verification and validation studies were conducted to confirm the safety and effectiveness of the new remote-access features and enhanced cybersecurity controls. No clinical performance data was required as the analytical performance remains unchanged from the predicate.

Technological Characteristics

Connectivity: Cloud-based architecture for remote software/OS updates and desktop sharing. Software: Windows 10 (v6.5.3) with enhanced cybersecurity (MS BitLocker, Digital Signature, MS AppLocker).

Indications for Use

Indicated for in vitro diagnostic coagulation and fibrinolysis testing in clinical laboratories using human citrated plasma samples.

Regulatory Classification

Identification

A coagulation instrument is an automated or semiautomated device used to determine the onset of clot formation for in vitro coagulation studies.

Special Controls

*Classification.* Class II (special controls). A fibrometer or coagulation timer intended for use with a coagulation instrument is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.

Dear Sneh Pingle:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding

{1}------------------------------------------------

When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

### Device Description

The ACL TOP Family 50 Series are fully automated coagulation analyzers that utilize the same intuitive software, the same consumables, reagents, calibrators and controls, and provide the same analytical methodology for routine and specialty assay result reporting as the predicate ACL TOP Family.

The ACL TOP Family 50 Series instrument performs the following types of tests, using the same optical measuring wavelengths and test parameters as the predicate ACL TOP Family:

- Coagulometric (Turbidimetric) Measurements
- . Chromogenic (Absorbance) Measurements
- . Immunological Measurements

The ACL TOP Family 50 Series also offers new pre-analytical features not available on the current ACL TOP Family as described below. These features are not intended to replace laboratory quality policies. The features simply alert the instrument operator to a potential HIL (Hemoglobin, Icteric and Lipemia) interference situation specific to the assays requested for a sample, underfilled sample tubes or a detected clog. The user will determine how to handle these situations (for example, by not reporting the results, or reporting the results with, or without, additional comments).

#### Intended Use / Indications for Use

The ACL TOP Family 50 Series (ACL TOP 750; ACL TOP 750 CTS; ACL TOP 750 LAS; ACL TOP 550 CTS; ACL TOP 350 CTS) are bench top, fully automated, random access analyzers designed specifically for in vitro diagnostic clinical use in the hemostasis laboratory for coagulation and/or fibrinolysis testing in the assessment of thrombosis and/or hemostasis. The systems provide results for both direct hemostasis measurements and calculated parameters.

### Special Conditions for Use Statement

· For prescription use only.

{5}------------------------------------------------

### Reason for Special 510(k) Submission

The new remote features introduced on the ACL TOP Family 50 Series are limited to adding permissionbased remote-control function for desktop sharing and remotely delivering software, OS updates (patches) and test parameter releases, utilizing security and privacy controls by design and installed by default. These features do not impact the analytical performance of the instrument and are already available on the ACL TOP Family 70 Series, FDA cleared under K231031.

The new remote features will be available to customers as an "optional add-on service" software tool called ProDx. This service software tool (ProDx) is being expanded beyond consistent monitoring, data gathering and capturing of quality control logs to now also include the following new remote features that are the subject of this Special 510(k):

- Added permission-based remote-control function for desktop sharing. ●
- Added functionality to remotely deliver software, OS updates (patches) and test parameter ● releases.

The above features are managed through cloud architecture for seamless and secure deployment; the same cloud architecture as already used on the ACL TOP Family 70 Series.

These new features will be available only for ACL TOP Family 50 Series instruments at Windows 10 (SW version 6.5.3). The features will not be available for ACL TOP Family 50 Series instruments at Windows 7.

#### Conclusion

The technological and functional characteristics of the ACL TOP Family 50 Series (subject device) as described herein are substantially equivalent to that of the ACL TOP Family 50 Series (predicate device). The software verification and validation study results demonstrate that the ACL TOP Family 50 Series with updated nonanalytical features is safe and effective for its intended purpose and equivalent in performance to the predicate device (K150877).
