Intended Use

P3T™ Cardiac is intended for use with CT Angiography. P3T™ Cardiac computes individual contrast injection protocols and scan timing, based on patient characteristics, scanner parameters and contrast concentration. The user will be required to confirm/change the suggested protocol before beginning an injection.

Device Story

Syringe-based fluid delivery system for contrast media in CT procedures; includes P3T™ Cardiac software accessory. Input: patient characteristics, scanner parameters, contrast concentration. Transformation: software computes individualized contrast injection protocols and scan timing. Output: suggested injection protocol displayed on injector LCD. Usage: clinical setting; operated by technologists. Workflow: user confirms or modifies suggested protocol before injection. Benefit: generates patient-specific protocols; increases consistency of injection protocols among technologists.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and performance comparisons to the predicate device.

Technological Characteristics

Syringe-based fluid delivery system; dual syringe model; color LCD display; non-dedicated software-determined keys; flow rate 0.1-10.0 mL/sec; pressure limit 50-325 psi; multi-layered software safety stops; connectivity via Imaging System Interface (ISI).

Indications for Use

Indicated for CT Angiography of cardiac structures, coronary arteries, heart chambers, pulmonary vasculature, and thoracic and abdominal aorta.

Regulatory Classification

Special Controls

*Classification.* Class II (special controls). The device, when it is a non-patient contacting balloon inflation syringe intended only to inflate/deflate balloon catheters and monitor pressure within the balloon, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

DEVICE DESCRIPTION AND COMPARISON TO PREDICATE: The MEDRAD

Stellant CT Injector System with P3T™ Cardiac is a syringe-based fluid delivery system indicated for delivery of contrast media during computed tomography procedures. The MEDRAD Stellant CT Injector System is intended for the specific purpose of injecting intravenous contrast media into humans for diagnostic studies in computed tomography (CT) applications.

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

MEDRAD Stellant CT Injector System operating software includes P3T™ Cardiac, an optional, password-enabled software accessory. The injector system, when used with P3T™ Cardiac, maintains the same intended use, same operational parameters, and same labeling (with the addition of the P3T™ Cardiac operation manual), and is used in the same manner as the injector system without the software accessory.

The P3T™ Cardiac software accessory provides the convenience of generating patientspecific contrast injection protocols, and increases the consistency of individualized injection protocols among technologists.

The purpose of this submission is to obtain FDA clearance of the expansion of the indications of MEDRAD's previously cleared device, Stellant CT Injector System with P3T™ CardiacFlow.

A comparison of features and principles of operation between the proposed device and predicate device is provided in Table 1 on the following page.

Dear Mr. Fortunato:

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 (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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). For questions regarding postmarket surveillance, please contact CDRH's Office of Surveillance and Biometrics' (OSB's) Division of Postmarket Surveillance at 240-276-3474.
