Intended Use

The HEMOCHRON® Signature Elite™ Whole Blood Microcoagulation System is a battery-operated, hand-held instrument that performs individual point-of-care coagulation tests on fresh or citrated whole blood. The system is intended to be used with test cuvettes that are available from ITC. For in vitro Diagnostic Use.

Device Story

Battery-operated, hand-held point-of-care instrument for quantitative coagulation testing (ACT, APTT, PT). Input: fresh or citrated whole blood sample placed in single-use disposable cuvette. Operation: instrument warms cuvette; mechanical-optical system pumps blood back and forth in test channel; LED detectors monitor blood movement; clotting endpoint recorded when movement decreases below threshold. Output: clotting time (seconds), correlated plasma equivalent values, and INR displayed on LCD. Features barcode scanner for patient/operator ID and assay parameter entry; stores up to 600 patient/QC results. Used by clinicians in point-of-care settings. Data management via PC connectivity (Configuration Manager, Report Maker, idms software). Benefits: rapid, bedside coagulation monitoring for clinical decision-making.

Clinical Evidence

No new clinical data provided. Analytical performance (accuracy, precision, linearity, carryover, interfering substances) relies on data previously cleared for the predicate device (K020798).

Technological Characteristics

Battery/AC-operated hand-held instrument. Mechanical-optical clot detection using LED sensors. Disposable test cuvettes. Connectivity: RS-232 and external ports. Software: Microsoft Windows-based configuration and reporting tools. Complies with IEC 60825-1 (laser safety), ISO 14971 (risk management), and ISO 9001/13485 (design verification).

Indications for Use

Indicated for use in clinical settings requiring point-of-care coagulation testing on fresh or citrated whole blood. Provides clotting times (seconds), Celite® equivalent ACT, APTT/PT plasma equivalents, and PT INR.

Regulatory Classification

Identification

#### Device Information

HEMOCHRON® Signature Elite™ Whole Blood Microcoagulation System Proprietary Name: Microcoagulation Analyzer Common Name: Multipurpose system for In-Vitro Coagulation (21 CFR 864.5425) Classification Name: Device Class: 11 Hematology & Pathology Panel: 81JPA Product Code:

#### Predicate Device

Substantial equivalence is claimed to the currently marketed International Technidyne Corporation's HEMOCHRON® Jr. Signature+ Whole Blood Microcoagulation System (K 020798).

#### Description of Device

The HEMOCHRON® Signature Elite™ Whole Blood Microcoagulation System is a batteryr ne real over to re in the nement that performs individual point-of-care coagulation tests on fresh or operated, norial morantents include: Activated Clotting Time (ACT+ and ACT-LR), Activated Partial Thromboplastin Time (APTT and APTT Citrate), and Prothrombin Time (PT and PT Citrate). The system is intended to be used with test cuvettes that are available from ITC.

Data management capabilities are included with the instrument. These capabilities include Storage of up to 600 patient results and 600 quality control results, designation of quality control levels, tagging of test results with date and time, entry of Patient ID and/or Operator ID or levers, tagging of toot room and bate HEMOCHRON® Configuration Manager software is included with the instrument. This software allows the user to connect a personal computer to the included with the instrument. This octtivation functions using a Microsoft Windows® user interface. HEMOCHRON® ReportMaker" and idms " software which are provided separately, allow the user to connect a personal computer to the instrument and perform various data management and data reporting functions.

#### Intended Use:

The HEMOCHRON® Signature Elite™ Whole Blood Microcoagulation System is a battery-The Hillioon Nort One Ognatan operated, nand-field increment mindude: Activated Clotting Time (ACT+ and ACT-LR), Activated Partial Thromboolastin Time (APTT and APTT Citrate), and Prothrombin Time (PT and PT Citrate). The system is intended to be used with test cuvettes that are available from ITC.

For in vitro Diagnostic Use.

## Technological Comparison to Predicate

The HEMOCHRON® Signature Elite™ performs the same assays as the predicate instrument. It rine heation system of the closed in method and clot detection algorithms as the predicate device. The submitted instrument design upgrades the user interface, data storage and data. manipulation functions. The instrument provides a secondary information input pathway using a manipulation farrenoner in addition to manual keypad entry, and offers a larger capacity to store data.

HEMOCHRON® Configuration Manager, which was cleared in the same 510(k) as the predicate device, is a Microsoft Windows® based software application. This software allows the user to configure the instrument to meet specific user needs in the clinical setting. The functionality of configure the instrument to meet specific user nocus in the cannounce of the rature filled in the laterially as the predicate device.

## Substantial Equivalence Data Summary

## Laboratory Comparison to Predicate

Laboratory Companson to Fredicate
The HEMOCHRON® Signature Elite " and predicate HEMOCHRON® Jr. Signature+ instruments were compared in the laboratory using ITC whole blood control products for each currently Were compared in the HEMOCHRON® Jr. Signature+ instrument (predicate).

## Clinical Comparison to Predicate

Olinical ochipanison to Production to the HEMOCHRON® Signature Elite™ clinical comparison to the predicate HEMOCHRON® Jr. Signature+ instrument system. The evaluation compared results obtained using split patient blood samples on the two instrument systems using each currently 510(k) cleared assay for the HEMOCHRON® Jr. Signature+ instrument system.

## Clinical User Interface Evaluation

A user-based evaluation of the clinical utility and ease of use of the instructional format displayed on the HEMOCHRON® Signature Elite™ instrument system when compared to the predicate HEMOCHRON® Jr. Signature+ instrument system was performed.

#### All clinical and laboratory data demonstrate the substantial equivalence of the HEMOCHRON® Signature Elite™ instrument system to the predicate HEMOCHRON® Jr. Signature+ instrument system.
