The description focuses on mechanical components and established stereotactic principles for target localization and fixation. There is no mention of AI or ML in the device description, intended use, or performance studies.
No.
The device itself is a stereotactic system for target localization and fixation during neurosurgical procedures, not for providing therapy directly. It enables therapeutic procedures like deep brain stimulation or tumor treatments, but it is a navigational and fixation tool.
No
This device is used for target localization, fixation, and guidance during neurosurgical procedures, but it does not perform a diagnostic function of identifying or characterizing a disease or condition. It is a surgical tool.
No
The device description explicitly states the system consists of a head frame, fixation pins, accessories for frame application and imaging, a stereotactic arc, and operating room accessories, all of which are hardware components.
Based on the provided information, the Leksell® Vantage™ Stereotactic System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states "target localization and fixation of the patient head in a coordinate system in order to perform stereotactic neurosurgical procedures". This describes a device used on the patient for surgical guidance and intervention, not a device used to examine specimens from the patient outside the body.
- Device Description: The description details a system for fixing the patient's skull and brain, enabling coordinate referencing for surgical procedures. It mentions instruments like biopsy needles and cannulas, but these are used in vivo (within the living body) for procedures, not for in vitro (in glass/outside the body) diagnostic testing.
- Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing biological samples (blood, tissue, etc.) or performing diagnostic tests on them.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic purposes. The Leksell® Vantage™ Stereotactic System is a surgical guidance and fixation system used directly on the patient during neurosurgical procedures.
N/A
Intended Use / Indications for Use

Device Description
The Leksell® Vantage™ Stereotactic System is a device used for minimally invasive neurosurgical procedures. It enables coordinate referencing and fixation of the patient's skull and brain during image acquisition and treatment. The coordinate referencing enables target localization and accurate stereotactic treatment of brain targets; for example for aspirations and biopsies, electrode placements, injections of cells & drugs, heamatoma evacuations as well as lesioning using a number of methodologies.
The system consists of a head frame that is fixated to the patient skull by minimally invasive disposable fixation pins and a number of accessories for frame application and imaging as well as a stereotactic arc and operating room accessories for the sterile surgical procedure.
The system is based on the established Leksell center-of-arc principle, which allows guidance of compatible interventional instruments at any trajectory angle to the brain target. Compatible interventional instruments are based on the Leksell principle of an active working length of 190 mm (as the arc radius) and use the correct mechanical interfacing of the Arc instrument stop and guide holders. Various instruments, such as biopsy needles, cannulas, and electrodes can be used with the system to perform biopsies, hematoma evacuation and injections of radioactive nuclides and cytostatic agents, puncture of cysts, positioning electrodes for stimulation/ recording or lesioning and stereotactic endoscope guidance.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical testing was deemed not required to demonstrate substantial equivalence with the predicate devices.
The verification activities have covered requirements at system and subsystem level to show that the design output meet the design input.
Design and usability validation of the system has been performed by competent and professionally qualified personnel to ensure that the product fulfils the intended use and user needs. The design and usability validation was also made to ensure that the risk control measures associated with functions related to safety (FRS) was effective.
Results from verification and validation testing demonstrates that conformance to applicable technical requirement specifications and user needs have been met showing that the system is safe to use and is substantially equivalent to the predicate devices.
Test: Sterilization
Test Method Summary: Sterility validation (EtO) according to ISO 11135:2014 was performed to demonstrate that the device have a sterility assumed level (SAL) of 10-6. The tests were performed on the predicate device Leksell® Vantage™ Stereotactic System (K171123).
Results: Results met pre-established acceptance criteria, demonstrating equivalence to the predicate device in terms of sterility.
Test: MR testing
Test Method Summary: The device was subjected to compliance testing to applicable consensus safety standards, such as: ASTM F2052; ASTM F2119; ASTM F2182, ASTM F2213 and ASTM F2503, and FDA guidance regarding safety and compatibility in the MR environment.
Results: The result demonstrates that the device is compliant to the FDA guidance and applicable consensus standards. This compliance demonstrates substantial equivalence.
Test: Accuracy
Test Method Summary: Accuracy was tested on different levels of the subject device: - Total system accuracy from imaging to treatment. - Total mechanical accuracy of the system - Mechanical accuracy of each component - Handling accuracy of various steps like repeated mounting of parts to each other and scale setting accuracy. - Displacement from load of head when fixed in the frame.
Results: All test cases were passed, demonstrating that the overall system accuracy of the Vantage system when used with the CT accessories is substantial equivalent to the predicate device.
Test: Design and Usability validation
Test Method Summary: Design and usability validation of the system has been performed by trained competent and professionally qualified personnel to ensure that the product fulfils the intended use and user needs.
Results: No unacceptable human factor risks were identified. Residual risks have been weighted against the benefit of the product and are deemed acceptable demonstrating that the Leksell® Vantage™ Stereotactic System used with the CT accessories is substantial equivalent to the predicate device.
