Intended Use
The Neoprobe® Model 1500 Portable Radioisotope Detector is an electronic device intended to detect and quantify gamma radiation. It is indicated for external and intraoperative detection of radioactivity in body tissues or organs, such as bowel, bone, lymphatics, and red blood cells, where radiopharmaceuticals are administered.
Device Description
The Neoprobe® Model 1500 Portable Radioisotope Detector ("Model 1500") consists of (1) a microcomputer-based control unit: (2) a 12 mm collimated detector probe tip, a 12 mm non-collimated detector probe tip, and a 19 mm noncollimated probe tip, all of which are reusable, steam sterilizable and contain a cadmium zinc telluride crystal gamma ray detector; (3) a disposable sterile probe handle with an attached polypropylene cable; (4) a check source disk containing a known quantity of 1201; and (5) a chrome-plated Teflon-lined lead noise adjustment fixture used for periodic verification that the system continues to meet factory calibration readings.
More Information

No
The description focuses on the hardware components and basic radiation detection functionality. There is no mention of AI, ML, or any algorithms that would suggest learning or adaptive capabilities.

No
The device is strictly for detection and quantification of gamma radiation and does not describe any therapeutic function.

Yes

The device is intended to "detect and quantify gamma radiation" in "body tissues or organs" where radiopharmaceuticals are administered, and it is indicated for "external and intraoperative detection of radioactivity," which points to its use in identifying and localizing specific physiological processes or abnormalities indicative of disease.

No

The device description explicitly lists multiple hardware components, including a control unit, detector probe tips, a disposable handle, a check source disk, and a noise adjustment fixture. This indicates it is a hardware device with associated software, not a software-only medical device.

Based on the provided information, the Neoprobe® Model 1500 Portable Radioisotope Detector is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended use clearly states that the device is for "external and intraoperative detection of radioactivity in body tissues or organs". This involves detecting radiation within the body, not analyzing samples outside the body (which is the hallmark of an IVD).
  • Device Description: The description details a system for detecting gamma radiation directly from tissues and organs using probes. There is no mention of collecting or analyzing biological samples like blood, urine, or tissue biopsies in a laboratory setting.
  • Anatomical Site: The device is used to detect radiation in "body tissues or organs". IVDs typically analyze samples derived from these sites, but not the sites themselves directly.

In summary, the Neoprobe® Model 1500 is a device used for in vivo (within the living body) detection of radioactivity, not in vitro (in glass, or outside the living body) analysis of biological samples.

Summary of Performance Studies

Neoprobe has conducted laboratory studies to demonstrate the functional equivalence of the Model 1500 12 mm reusable, steam sterilizable noncollimated and collimated detector probe tips to the cleared Model 1000 GEN 1C 11 mm, EtO sterilizable detector probe. The tests performed on the cleared 11 mm and the new 12 mm collimated and non-collimated probe tips included measurement of the counting efficiency as a function of probe to source distance for 1351, 1111n and 99mTc, and measurement of the spacial resolution of the probe tip with and without collimation for the three nuclides. The results obtained with the cleared 11 mm probe and the new 12 mm probe tips demonstrate that the two types of detector probes are functionally equivalent except for the change in count rate that is predicted from the change in dimensions of the crystal. In terms of counts per second per unit, area of detector surface were the same for both the 11 mm and the 12 mm detector probe tips. The collimated and non-collimated versions of the reusable, steam sterilizable detector probes can be used interchangeably with the Neoprobe® 1500 control unit with the same disposable handle, without adjustments.

Neoprobe has submitted in previous 510(k) notifications (including K942580 and K864263) literature in support of the indications for use for which the company is seeking clearance in this submission. Specifically, literature has been supplied to FDA on the use of various radiopharmaceutical compounds and detector probes for intraoperative identification of areas with increased radionuclide concentration to support the use of Neoprobe's device during ischemic bowel, bone (osteoid osteoma), thyroid and colon applications. In addition, this 510(k) notice includes literature that supports the use of Neoprobe's Model 1500 for detection of radioactivity in lymphatics.

It is indicated for external and intraoperative detection of radioactivity in body tissues or organs, such as bowel, bone, lymphatics, and red blood cells, where radiopharmaceuticals are administered.

Device Description

The Neoprobe® Model 1500 Portable Radioisotope Detector ("Model 1500") consists of (1) a microcomputer-based control unit: (2) a 12 mm collimated detector probe tip, a 12 mm non-collimated detector probe tip, and a 19 mm noncollimated probe tip, all of which are reusable, steam sterilizable and contain a cadmium zinc telluride crystal gamma ray detector; (3) a disposable sterile probe handle with an attached polypropylene cable; (4) a check source disk containing a known quantity of 1201; and (5) a chrome-plated Teflon-lined lead noise adjustment fixture used for periodic verification that the system continues to meet factory calibration readings.

Safety and Effectiveness

The Model 1500 is substantially equivalent to the Model 1000 GEN 1C, which received premarket clearance in 1996 (K92319). This submission covers modifications to the device since the Model 1000 GEN 1C received premarket clearance. These modifications include: (1) a modified control unit, (2) a disposable detector probe handle with attached cable, (3) a 12 mm noncollimated reusable, steam sterilizable detector probe tip, (4) a 12 mm collimated reusable, steam sterilizable reusable detector probe tip, and (5) a 19 mm noncollimated reusable, steam sterilizable detector probe tip. These modifications are intended to facilitate rapid and efficient probe interchangeability and to offer more options to the user.

Neoprobe has conducted laboratory studies to demonstrate the functional equivalence of the Model 1500 12 mm reusable, steam sterilizable noncollimated and collimated detector probe tips to the cleared Model 1000 GEN 1C 11 mm, EtO sterilizable detector probe.
