More Information

Varian UNIQUE (K101751)

No
The summary does not mention AI, ML, or any related terms, and the device description focuses on standard linear accelerator technology and treatment techniques.

Yes
The device is described as a "radiotherapy delivery system" and a "medical linear accelerator that delivers therapeutic radiation to patient," which directly indicates its use for treatment.

No

The primary purpose of the VenusX radiotherapy delivery system is therapeutic (delivering radiation treatment), not diagnostic. While it has a "photon diagnostic kV X-ray radiation beam producing component," this is likely for positioning or verification of the treatment area rather than for disease diagnosis.

No

The device description explicitly states it is a "medical linear accelerator" and includes components like a "photon therapeutic 6 MV X-ray radiation beam producing component" and a "photon diagnostic kV X-ray radiation beam producing component," which are hardware. The performance studies also mention hardware verification and validation testing.

Based on the provided information, the VenusX radiotherapy delivery system is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens derived from the human body in order to provide information for diagnostic, monitoring or compatibility purposes. This typically involves analyzing blood, urine, tissue samples, etc.
  • VenusX Function: The VenusX system is a medical linear accelerator that delivers therapeutic radiation to the patient's body for treatment. It does not analyze specimens outside the body.
  • Intended Use: The intended use clearly states "to provide precision radiotherapy for lesions, tumors, and conditions anywhere in the body where radiation treatment is indicated." This is a therapeutic, not diagnostic, application involving direct interaction with the patient.
  • Device Description: The description details a system that produces and delivers radiation beams to the patient.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components associated with IVD devices.

Therefore, the VenusX radiotherapy delivery system falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

IX. CONCLUSION FOR SUBSTANTIAL EQUIVALENCE TO THE PREDICATE AND REFERENCE DEVICE

The VenusX is substantially equivalent to the UNIQUE (K101751) (predicate device). The intended use is the same with precision radiotherapy as the predicate device. VenusX does not support stereotactic radiosurgery. A subset of technological characteristics and features of the current device is different to the predicate. However, the Verification and Validation demonstrate that the device is as safe and effective as the predicate and reference device. Based on the comparison and analysis above, the VenusX (subject device) is substantially equivalent to the UNIQUE (K101751) (predicate device).
