The device description explicitly details physical components like a thermoplastic handle, stainless steel tip, and passive reflective sphere markers. The performance studies focus on dimensional analysis and compatibility with a hardware system (Medtronic StealthStation® System), indicating it is a physical accessory, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Definition of IVD: An In Vitro Diagnostic device is a medical device that is used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
- Intended Use: The intended use of the Disposable Passive Accessory is for "anatomy palpation in image guided surgeries." This involves interacting with the patient's anatomy during a surgical procedure, not analyzing samples taken from the patient.
- Device Description: The device description clearly states it's a "disposable point probe" with reflective markers used to "register and locate patient anatomical structure in an image guided surgery." This is a tool for surgical navigation and localization, not for diagnostic testing of biological samples.
The device is a surgical accessory used in conjunction with an image-guided surgery system. It helps the surgeon track the position of the probe relative to the patient's anatomy based on pre-operative imaging. This is a surgical tool, not a diagnostic test.

V. INDICATIONS FOR USE
The Disposable Passive Accessory is intended to be used for anatomy palpation and registration in image guided surgeries with Medtronic StealthStation system. The device is sterile and designed for single use.
The indication for use statement for the Disposable Passive Accessory is very similar to the labeled indication for use of the Medtronic Passive Planar Probe, however, the predicate device is an accessory part of the Medtronic StealthStation System. The Medtronic 510(k) K050438 indication for use emphasizes the System and applicable procedures, and the specific indication of use for each accessory part is not clearly stated in the 510(k). The minor difference of the subject device and the predicate device is that the subject device is single use and provided to the user as a sterile device. This does not affect the intended surgical use of the device. The IZI Spherz are a component part of the subject device. The subject device uses the Spherz within the scope of indication for use of the Spherz.
Patient Population
The device is intended for use in patients undergoing stereotactic surgery.
Environment of Use
The device is intended for use by a trained healthcare professional in a healthcare facility.
VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

VII. PERFORMANCE DATA
Two non-clinical bench tests were conducted to demonstrate that the IZI Disposable Passive Accessory performs as intended and is comparable to the predicate devices.
- Design Verification - Dimensional Analysis of the IZI Disposable Passive Accessory Probe. The System calculates and determines the position and angle of the probe based on the three dimensional location of the five passive reflective sphere markers that are mounted on the probe. Dimension accuracy and precision is an important technical characteristic that ensures the subject device is compatible with the StealthStation® System and that the subject device is comparable to the predicate device. A dimensional analysis of the Disposable Passive Accessory and the predicate device was performed to ensure the disposable part meets engineering specifications and the subject device is as precise and accurate as the predicate device. All critical dimensions that affect the passive reflective marker locations and the probe tip location
7
were measured in the Study against the predicate device. The CpK of all dimensions are greater than 1.0.
- Design Verification - IZI Disposable Accessory with the Medtronic StealthStation S7 The Study was conducted to ensure the compatibility of the devices with the Medtronic StealthStation® system and confirming it is suitable for its intended use. The Study verified product performance in the StealthStation® patient registration process and measured navigation accuracy using a pre-scanned Medtronic IGS dummy head. Regarding patient registration and navigation error, the IZI Disposable Passive Accessory performs comparably to the Medtronic Planar Probe with manually mounted Spherz.
The two studies verify that the subject device is as safe and effective as the predicate device, and that the subject device is comparable to the predicate device.
VIII. CONCLUSION
The non-clinical data support the safety of the device and the hardware verification and validation demonstrate that the IZI Disposable Passive Accessory device should perform as intended in the specified use conditions. The non-clinical data demonstrate that the IZI Disposable Passive Accessory device performs comparably to the predicate device that is currently marketed for the same intended use.
