No.
This device is an in vitro diagnostic (IVD) system used to identify bacteria and determine their susceptibility to antimicrobial agents. It does not directly treat or diagnose a disease in a living patient, but rather provides information used by clinicians.
Yes
The device is intended for "in vitro quantitative determination of antimicrobial susceptibility by minimal inhibitory concentration (MIC)" and "rapid identification (ID) and antimicrobial susceptibility testing (AST) of clinically relevant bacterial isolates," which are diagnostic procedures to determine the characteristics of a disease-causing agent.
No
The device description clearly states that the system includes hardware components such as the BD Phoenix instrument, panels, and broths, in addition to the software. While the software is a key part of the system, it is not the sole component.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the system is intended for "in vitro quantitative determination of antimicrobial susceptibility." This clearly indicates that the device is used to perform tests on samples taken from the body (in vitro) to diagnose or provide information about a medical condition (antimicrobial susceptibility).
- Device Description: The description details components like "BD Phoenix panels containing biochemicals for organism ID testing and antimicrobial agents," "BD Phoenix ID Broth," and "BD Phoenix AST Broth." These are all reagents and consumables used in laboratory testing of biological samples.
- Functionality: The system performs "rapid identification (ID) and antimicrobial susceptibility testing (AST) of clinically relevant bacterial isolates." This is a standard function of IVD devices used in clinical microbiology laboratories.
- Output: The system provides "identification of the isolate, minimum inhibitory concentration (MIC) values and category interpretations, S, I, or R (sensitive, intermediate, or resistant)." These are diagnostic results used by healthcare professionals to guide treatment decisions.
The entire description points to a device designed and used for laboratory testing of biological samples to provide diagnostic information, which is the definition of an In Vitro Diagnostic device.

Device Description
The BD Phoenix Automated Microbiology System (Phoenix System) is an automated system for the rapid identification (ID) and antimicrobial susceptibility testing (AST) of clinically relevant bacterial isolates. The system includes the following components:
- . BD Phoenix instrument and software.
- BD Phoenix panels containing biochemicals for organism ID testing and antimicrobial agents . or AST determinations.
- BD Phoenix ID Broth used for performing ID tests and preparing AST Broth inoculum. ●
- . BD Phoenix AST Broth used for performing AST tests only.
- . BD Phoenix AST Indicator solution added to the AST Broth to aid in bacterial growth determination.
Software incorporated into the BD Phoenix™ Automated Microbiology System provides the user with the ability to process Phoenix ID and/or Phoenix AST panels in a walk-away fashion. The software allows for the establishment of a panel test, automated/unattended testing of the panel and the ability to review the panel results. In order to accomplish the overall general purpose of the instrument, the software provides users with the ability to interact with the instrument, when necessary to facilitate the testing that they require. The Phoenix software includes the BDXpert System which is a collection of rules intended to evaluate results for specific organism-drug combinations.
The BDXpert System that is resident on the EpiCenter System is basically the same Expert system that exists on the Phoenix System. However, the BDXpert System utilizes additional information, such as specimen site, to provide the user with a more refined SIR interpretation.
The Phoenix software was developed and tested according to its Software Dcvelopment Plan and Software Verification and Validation Plan. The software test results demonstrated that the software operated in accordance to the software specifications
The Phoenix panel is a sealed and self-inoculating molded polystyrene tray with 136 micro-wells containing dried reagents. Organisms for susceptibility testing must be a pure culture and preliminarily identified as a Gram-negative or Gram-positive isolate. For each isolation equivalent to a 0.5 McFarland standard is prepared in Phocnix ID broth.
The Phoenix AST mothod is a broth based microdilution test. The Phoenix system utilizes a redox indicator for the detection of organism growth in the presence of an antimicrobial agent. Measurements of changes to the indicator as well as bacterial turbidity are used in the determination of bacterial growth. Each AST panel configuration contains several antimicrobial agents with a wide range of two-fold doubling dilution concentrations.
The instrument houses the pancls where they are continuously incubated at a nominal temperature of 35°C. The instrument takes readings of the pancls every 20 minutcs. The readings are interpreted to give an identification of the isolate, minimum inhibitory concentration (MIC) values and category interpretations, S, I, or R (sensitive, intermediate, or resistant).

DEVICE COMPARISON:
The modifications to Phoenix Instrument Software through Version 4.0 and the BDXpert System resident on the EpiCenter System, as described in this submission, are substantially equivalent' to BD Phoenix™ Automated Microbiology System with Gatifloxacin (K020321, May 23, 2002), Offloxacin (K020323, April 14, 2002), and I.evofloxacin (K020322, March 27, 2002) (also referred to as previously submitted Phoenix Instrument software).
The term "substantial equivalence" as used in this 510(k) notification is limited to the definition of substantial equivalence as found in the Federal Food, Drug and Cosmetic Act, as amended and as applied under 21 CFR 807, Subpart E under which a device can be marketed without pro-market approval or reclassification. A determination of substantial equivalency under this not ison is not intended to have any bearing whatsoever on the resolution of patent infringement suits or any other patent matterns. related to, or in support of substantial equivalence herein shall be construed as an admission against under tro U.Patint Laws or their application by the courts.

The modifications to Phoenix Instrument Software through Version 4.0 and the BD Phoenix™ Automated Microbiology System (K020321, K020323, and K020322) are similar in that they have the same intended use and automatically provide the user with antimicrobic minimum inhibitory concentration (MIC) results and SIR interpretations. The modifications to Phoenix Instrument Software through Version 4.0 and the BD Phoenix™ Automated Microbiology System (K020321, K020323, and K020322) are different because of new features introduced into the software as described in this submission.
The BDXpert System resident on the EpiCenter System is similar to the BD Phoenix™ Automated Microbiology System (K020321, K020323, and K020322) in that both automatically provide the user with reports containing antimicrobic minimum inhibitory concentration (MIC) results and SIR interpretations. The BDXpert System resident on the EpiCenter System is different from the BD Phoenix™ Automated Microbiology System (K020321, K020323, and K020322) in that the BDXpert System resident on the EpiCenter System in itself does not actually perform the analysis of the test panels. The BD Phoenix™ Automated Microbiology System actually performs the test analysis. Also the BDXpert System resident on the EpiCenter System utilizes additional information, such as specimen type, to determine the BDXpert SIR interpretation. The BD Phoenix™ Automated Microbiology System does not use this information when determining the BDXpert SIR interpretation.
Although there are some differences between the BD Phoenix™ Automated Microbiology System and the reference method and predicate device, these differences do not raise new issues of safety and effectivencss.
In review of previous 510(k) premarket notifications for the BD Phoenix™ Automated Microbiology System with Gatifloxacin (K020321, May 23, 2002), with Ofloxacin (K020323, April 14, 2002), and with Levofloxacin (K020322, March 27, 2002) the Food and Drug Administration (FDA) has determined the Phocnix system to be substantially equivalent to devices market
