The Anzai eZ-Scope AN Portable Gamma Camera is indicated for use to image the distribution of radionuclides in the human body using planar imaging techniques. The eZ-Scope may be used intraoperatively or on pathological specimens if a protective sheath is used.
The Anzai EZ-Scope AN Portable Gamma Camera is a currently marketed portable gamma camera. utilizing a solid state detector. rather than a scintilator, to detect gamma rays. The cadmium-zinc-tellurium detector allows sharp energy discrimination and spatial resolution. The detector arrav is made from pixelized cadmium-zinc-telluride (CZT) crystals, with each of the 256 pixels having dimensions of 2 x 2 mm. The system is available in two configurations, eZ-Scope AN and eZ-Scope Light. These differ primarily in the computer, the former model using a desktop computer and the latter a laptop. In the desktop version, the computer is mounted on a cart, while the laptop version does not have a cart.
The present 510(k) is for an addition to the indications for use statement (see next section) pertaining to intraoperative use. The user manual has been modified to include instructions for disinfecting the camera head and covering it with a protective plastic sheath to prevent contamination of a sterile field in case of an accidental puncture of the sheath during intraoperative use.
The provided text states that "No new performance testing was necessary for the present submission." Therefore, it does not contain the information required to populate the acceptance criteria and study details. The submission is for an additional indication for use (intraoperative use) for an already legally marketed device, and the manufacturer claims substantial equivalence to predicate devices without the need for new performance testing.

510(k) Summary
Anzai eZ-Scope AN Portable Gamma Camera
Common/Classification Name: Gamma Camera, 21 CFR 892.1110
Anzai Medical Company, Ltd. 3-6-25 Nishi-Shinaqawa Shinagawa-ku Tokvo 141-0033 Japan
Contact: T. Kaneko, Prepared: July 17, 2002
LEGALLY MARKETED PREDICATE DEVICES A.
The eZ-Scope AN Gamma Camera is substantially equivalent to the currently marketed eZ-Scope AN Gamma Camera, which was cleared by FDA on May 28, 2002 as K020643. For the new indication for use, intraoperastive use, it is also substantially equivalent to the Neoprobe 2000 Isotope Probe (based on K971320 for the Neo 1500).
B. DEVICE DESCRIPTION
The Anzai EZ-Scope AN Portable Gamma Camera is a currently marketed portable gamma camera. utilizing a solid state detector. rather than a scintilator, to detect gamma rays. The cadmium-zinc-tellurium detector allows sharp energy discrimination and spatial resolution. The detector arrav is made from pixelized cadmium-zinc-telluride (CZT) crystals, with each of the 256 pixels having dimensions of 2 x 2 mm. The system is available in two configurations, eZ-Scope AN and eZ-Scope Light. These differ primarily in the computer, the former model using a desktop computer and the latter a laptop. In the desktop version, the computer is mounted on a cart, while the laptop version does not have a cart.
The present 510(k) is for an addition to the indications for use statement (see next section) pertaining to intraoperative use. The user manual has been modified to include instructions for disinfecting the camera head and covering it with a protective plastic sheath to prevent contamination of a sterile field in case of an accidental puncture of the sheath during intraoperative use.
C. INTENDED USE
The Anzai eZ-Scope Portable Gamma Camera is indicated for use to
{1}------------------------------------------------
image the distribution of radionuclides in the human body using planar imaging techniques. The eZ-Scope may be used intraoperatively or on pathological specimens if a protective sheath is used.
D. SUBSTANTIAL EQUIVALENCE SUMMARY
The eZ-Scope is a medical device, and it has the same indications for use, except for the addition of the phrase pertaining to intraoperative use, as the currently marketed version of the device. The indications for use for the Neoprobe gamma detector cover the indication for intraoperative use. The intended diagnostic effect is the same as the predicate devices. The eZ-Scope has the same (identical) technological characteristics as the currently marketed device.
E. TECHNOLOGICAL CHARACTERISTICS
The technological characteristics are the same as those of the currently marketed eZ-Scope.
F. TESTING
No new performance testing was necessary for the present submission.
G. CONCLUSIONS
This pre-market notification has demonstrated Substantial Equivalence as defined and understood in Sections 513(f)(1) and 513(i)(1) of the Federal Food Drug and Cosmetic Act and various guidance documents issued by the Center for Devices and Radiological Health.
