Intended Use

The WayPoint™ Stereotactic System is intended to be used with commercially available stereotactic systems for neurosurgical procedures which require the accurate positioning of microelectrodes, stimulating electrodes, implantable electrodes or other instruments in the brain or nervous system.

Device Story

WayPoint™ Stereotactic System (WPS) provides patient-customized stereotactic fixtures for neurosurgical procedures; facilitates microelectrode recording, stimulation, and device implantation. System inputs include scanned patient images; software (WayPoint™ Planner or VoXim®) processes images to design a patient-specific Stereotactic Platform Adapter. Components include anchor/locator system, platform adapter, and mounting hardware. Used in clinical settings by neurosurgeons to secure instruments to skull-based anchor sets. Provides sub-millimeter targeting accuracy; allows alignment of surgical instruments with patient anatomy. Benefits include improved precision in target reaching compared to conventional frames.

Clinical Evidence

Bench testing only. Phantom-based studies confirmed sub-millimeter accuracy of the Stereotactic Platform Adapter. Comparison of intraoperative stereotactic coordinates to postoperative CT images demonstrated accuracy comparable to conventional frames. Preoperative target selection and final placement verification based on CT images showed error measurements comparable to standard stereotactic frame procedures.

Technological Characteristics

Stereotaxic instrument (21 CFR 882.4560). System comprises patient-customized stereotactic fixtures, skull-based anchor mounting sets, platform adapters, and planning software. Connectivity involves integration with patient imaging data (CT).

Indications for Use

Indicated for patients undergoing neurosurgical procedures requiring accurate positioning of microelectrodes, stimulating electrodes, implantable electrodes, or other instruments within the brain or nervous system.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

# Description of device: (4)

The WayPoint™ Stereotactic System. (WPS System) accurately locates and rigidly supports neurosurgical or other surgical instruments relative to specific anatomical structures or targets, thus facilitating microelectrode recording, stimulation, data collection, device implantation and other surgical procedures. The WPS System provides patient-customized stereotactic fixtures designed to be secured on skull-based anchor mounting sets to hold and

{1}------------------------------------------------

align surgical instruments with patient anatomy and to allow selected targets to be reached with sub-millimeter accuracy. The WPS System consists of several components that work together to become a stereotactic system. These components are:

- 1) the WayPoint™ Stereotactic Anchor System:
- 2) the WayPoint™ Stereotactic Platform Adapter:
- 3) Device mounting hardware for the Platform; and,
- 4) WayPoint™ compatible Planning software such as:
- a. WayPoint™ Planner; or,
- b. VoXim®Planning software.

The WayPoint™ Stereotactic Anchor/Locator System provides tools and components for the temporary implantation of anchors to be used as reference points and mounting sets for the surgical procedure. The WPS System software designs a Stereotactic Platform Adapter that will mount to the WayPoint™ Stereotactic Anchor System. For each surgical instrument or device to be mounted to the Stereotactic Platform Adapter, suitable hardware is provided to act as a secure interface and allow flexibility in targeting, if required. The two existing software components of the WPS System (WayPoint™ Planner and VoXim® microTargeting™ Planning software) provide tools to create a Stereotactic Platform Adapter from scanned patient images.

## Statement of intended use: (5)

The WayPoint™ Stereotactic System is intended to be used with commercially available stereotactic systems for neurosurgical procedures which require the accurate positioning of microelectrodes, stimulating electrodes, implantable electrodes or other instruments in the brain or nervous system.

## (6) Comparison of Technological Characteristics to Predicate Devices:

The WayPoint™ Stereotactic System is substantially equivalent to the predicate devices in design, construction, materials, intended use and performance characteristics. No new issues of safety or effectiveness are introduced in the use of this device.

### B. Performance data

Both phantom- and imaging-based studies were conducted in order to evaluate the accuracy of the WPS System. Results from the phantom-based study showed that the Stereotactic Platform Adapter produced by the WPS System is accurate to a submillimetric level. Using the WPS System, a comparison of intraoperative stereotactic coordinates of an implant to its position in postoperative CT images demonstrated accuracies comparable to those of conventional frames. Finally, in a study that compared preoperative target selection and final placement verification based on CT images, error measurements were comparable to those for the same procedure as described by other groups using a standard stereotactic frame.
