The device is an in vitro diagnostic device used to detect and genotype specific point mutations in DNA, which aids in the diagnosis of suspected thrombophilia, rather than directly treating a condition.
Yes
The "Intended Use / Indications for Use" section explicitly states, "The INFINITI™ System Assay for Factor II & Factor V is an in vitro diagnostic device" and "is indicated for use as an aid to diagnosis in the evaluation of patients with suspected thrombophilia."
No
The device description clearly outlines multiple hardware components including a thermal cycler, imager, BioFilmChip Microarray, Intellipac Reagent Module, and the INFINITI Analyzer instrument with pipetting and optics modules. While it includes software, it is an integral part of a larger hardware system.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:

Device Description
The INFINITI System Assay for Factor II & Factor V is an in vitro diagnostic device which utilizes proprietary film-based microarray technology combined with process automation, reagent management and software technology for the detection and genotyping of the Factor II (Prothrombin) G20210A mutation and the Factor V Leiden G1691A mutation from deoxyribonucleic acid (DNA) isolated from human whole peripheral blood samples.
The INFINITI System Assay for Factor II & Factor V is comprised of the BioFilmChip" Microarray, the Intellipac™ Reagent Module, and the INFINITI Analyzer with the Qmatic" Operating Software.
The BioFilmChip Microarray consists of a polyester film coated with proprietary multi-layer components designed for DNA analysis. The layers have been designed to provide a versatile surface to enhance test performance. There can be up to 240 spots per microarray with each spot representing a different allele. The microarrays are designed to be assay specific.
The Intellipac Reagent Module which acts as a communication link contains up to eight reservoirs that house the test reagents and has an integrated memory chip. The assay protocol resides in this memory chip and upon request is loaded to the INFINITI Analyzer. Information such as expiration date of reagents, volume usage, time of use and operation parameters are archived in the memory chip and appear on the worklist (run report).
The INFINITI Analyzer is an instrument used for clinical multiplex systems intended to measure and sort multiple signals from a clinical sample. The INFINITI Analyzer is designed to measure fluorescence signals of labeled DNA target hybridized to BioFilmChip microarrays. The INFINITI Analyzer automates the Factor II and Factor V assays and integrates all the discrete processes of sample (PCR amplicon) handling, reagent management, hybridization, detection, and results analysis. The assays are processed automatically and read by the built-in confocal microscope. Results are analyzed and presented in numerical and graphical format.
The INFINITI Analyzer has two main components: pipetting and optics modules. A variety of electronic components inside the instrument are used for its operation. These include multiple stepper motors, heating and cooling devices, a barcode reader, a photomultiplier tube, and a camera all connected to USB ports
- . Pipetting Module - The pipetting module performs all the operations related to dispensing and aspiration of reagent and processing the amplified sample to be dispensed on the microarray. When the sample has been processed and hybridized to the microarray, it is transferred to the optics module for scanning and reading.
- . Optics Module - The optics module is a lightproof assembly comprised of a 3-axis stage: camera, lasers, and a photo multiplier tube (PMT). It is the enclosed casement into which the microarray is transported automatically prior to being processed on the stringency station. The optics' stage follows X-Y-Z motions that can be stepped at a very precise rate (2.0 micron per step). Using excitation wavelengths of a 760nm laser diode, the camera takes a 1.2x1.2mm picture for each registration spot of a fluorescent die. Analyses of these pictures allow the location of three registration spots to be determined. With respect to the position of the three registration spots, coordinates of all the bio-spots can be located. While scanning, the stage moves along the Z-axis to focus the chip and the X and Y-axes to locate the individual spots on the microarray.
The INFINITI Analyzer hardware is controlled by the Qmatic™ operating software, which is installed with-in the on-board computer and utilizes a LCD screen display. The INFINITI Analyzer modules are controlled by multitasking real time software. The Omatic "M operating software has a schedule manager that is capable of controlling all operations of the INFINITI Analyzer such as assay protocol, fluid handling, robotics, optical detection and result analysis. Results are available for review via the LCD screen. Management reports include results in numerical and graphical format. The operator can also print the displayed results in tabular form (printer not included with INFINITI Analyzer).
