Intended Use
The Stereo Navigator Accessory is an optional accessory to the PEM Flex® PET Scanner. It is intended for the localization of lesions in female breasts, as identified on a PET image. By using the Stereo Navigator, the physician is able to guide compatible interventional devices towards the PET abnormality as medically indicated. The Stereo Navigator also provides a means to confirm localization of the lesion in advance of the interventional procedure.
Device Description
The Stereo Navigator determines the three dimensional coordinates of a userdefined target for an imaged abnormality (e.g. lesion) displayed on the PEM Flex PET Scanner. Since PEM Flex tomographic images are displayed as a series of 2D planar slices, the user must define a target on two orthogonal images to define all three axis coordinates of the target location. These coordinates are processed into stereotactic information by the Stereo Navigator software which is used by the healthcare provider to position a stereotactic frame for guiding the trajectory of an interventional device and for determining the depth to which the interventional device should be inserted along the trajectory. Additionally, the Stereo Navigator provides a means for the user to confirm that localization has been achieved during the interventional procedure and prior to sampling or marking. This is accomplished by placing an encapsulated positronemitting line source (radioactive line source) through the tissue access port (cannula) of the interventional device to the intended sampling or marking site, acquiring an image and comparing the location of the line source relative to the lesion (in at least two orthogonal image planes).

No
The description focuses on user-defined target selection and geometric processing of coordinates, with no mention of AI or ML algorithms for image analysis or guidance.

No
The device aids in localization and guidance for interventional procedures but does not directly treat a condition. It assists in diagnosis/intervention, which precedes therapy.

No

The device is intended for localization of lesions and guiding interventional devices, as well as confirming localization; it does not identify or characterize a disease or condition for diagnostic purposes.

No

The device description explicitly mentions the use of a "positron-emitting line source (radioactive line source)" which is a hardware component used in the localization confirmation step. While the device utilizes software for processing coordinates, it is not solely software.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs are used to examine specimens derived from the human body. The Stereo Navigator Accessory works with a PET scanner to localize lesions within the female breast using imaging data. It does not analyze biological samples like blood, urine, or tissue.
  • The intended use is for guiding interventional devices and confirming localization in vivo. The device is used during a procedure on the patient, not for testing samples in a laboratory setting.

The device is a medical device used for image-guided intervention, specifically for breast lesions identified on PET images.

Intended Use / Indications for Use:

The Stereo Navigator Accessory is an optional accessory to the PEM FIcx® PET Scanner. It is intended for the localization of lesions in female breasts, as identified on a PET image. By using the Stereo Navigator, the physician is able to guide compatible interventional devices towards the PET abnormality as medically indicated. The Stereo Navigator also provides a means to confirm localization of the lesion in advance of the interventional procedure.

Technological Characteristics:

The Stereo Navigator determines the three dimensional coordinates of a userdefined target for an imaged abnormality (e.g. lesion) displayed on the PEM Flex PET Scanner. Since PEM Flex tomographic images are displayed as a series of 2D planar slices, the user must define a target on two orthogonal images to define all three axis coordinates of the target location.

Performance Data:

The Stereo Navigator was subject to preclinical (phantom) studies and confirmatory clinical studies. These studies demonstrated that the device is substantially equivalent to the predicates with respect to safety and effectiveness. Substantial Equivalence:

The Stereo Navigator is as safe and effective as the 1) Stereotactic Localization Device (SLD), 2) Confirma Breast MRI Interventional Components, and 3) SureLoc® CADstream 4.0 System, ("Predicate Devices"). The Stereo Navigator has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate devices. The minor technological differences between the Stereo Navigator and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that the Stereo Navigator is as safe and effective as the Predicate Devices. Thus, the Stereo Navigator is substantially equivalent.

Dear Ms. Jalisi:

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.
