WARNING LETTER

Dear Mr. Tribou:

During an inspection of your firm, TZ Medical, Inc., located at 7272 SW Durham Road, Suite 800, Portland, Oregon, from August 22-24, 2005, Mr. Dennis G. Kawabata, an investigator from the Seattle District Office of the Food and Drug Administration (FDA) determined that your establishment manufactures, markets, and distributes a device identified as the Booker Box System, which facilitates the connection between various products, including a defibrillator and EP catheters. Your firm also manufactures and distributes devices known as (1) PadTac Electrophysiology Recording Catheters, Junction Box Cable Connector, and Electrophysiology Connector Cable, K021421 (Junction Box Cable Connector), and, (2) Booker Box Defibrillation Cable Adaptor, K993205.

The products listed above are medical devices within the meaning of section 201(h) of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. § 321(h)), because they are intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, or to affect the structure or any function of the body.

Our review of information collected during the inspection revealed that, since being cleared for marketing, TZ Medical has combined the Junction Box Cable Connector and Booker Box Defibrillation Cable Adaptor into one new device, the Booker Box System.

In addition, a switch was added to the Booker Box Defibrillation Cable Adaptor in order to eliminate the need for connecting two defibrillators. The combination of the two devices as described, and the addition of a new switch, represents a significant change in the design or energy source of the device and requires the submission of a new 510(k) under 21 CFR 807.81(a)(3)(i). A review of our records reveals that no 510(k) submission has been received for the Booker Box System.

During the inspection, you provided our investigator with a Document Change Order and your justification for not submitting a new 510(k) for the new device. You justify not submitting a new 510(k) by stating that the combined devices have the same operating principles, technological characteristics, intended use, target population, and do not present any greater patient risk than the original 510(k) submissions. FDA disagrees with your conclusion. By combining the Junction Box Cable Connector with the Booker Box Defibrillation Cable Adaptor, a high voltage circuit and a low voltage circuit are being confined inside the same box, thereby increasing the risk of electromagnetic interference. Furthermore, the additional switch increases the risk in use of the device because there is a greater potential for the user to mistakenly connect the EP mapping catheters to the defibrillation parts installed on the box, possibly delivering a shock of up to 360 joules directly to the patient's heart. These changes represent significant changes in the design or energy source of the device.

The Booker Box System is misbranded under section 502(o) (21 U.S.C. § 352(o)), in that a notice or other information respecting the device was not provided to FDA as required by section 510(k), and as described under 21 CFR 807.81(a)(3)(i). The device is also adulterated within the meaning of section 501(f)(1)(B) of the Act (21 U.S.C. § 351(f)(1)(B)), in that it is a Class III device under section 513(f) and does not have an approved application in effect pursuant to Section 515(a) of an approved application for an investigational device exemption under section 520(g). For a device requiring premarket approval before marketing, the notification required by section 510(k) of the Act is deemed satisfied when a premarket approval application (PMA) is pending before the agency [21 C.F.R. 807.81(b)].
