• Device Name: REFLECTIVE SPHERE STANDARD PROBE AND REFLECTIVE SPHERE DYNAMIC REFERENCE FRAME
• Applicant: Radionics, Inc.
• Product Code: HAW · Neurology
• Decision Date: Nov 10, 1998
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 882.4560
• Device Class: Class 2

Intended Use

The Radionics OTS with Passive-Reflective Tracking Configuration is indicated for use in cranial and spinal surgical procedures in which anatomical landmarks are not clearly visible or where a desired target is close to critical structures.

Device Story

Radionics Optical Tracking System (OTS) modification; incorporates NDI Polaris Camera and passive reflective spheres on surgical accessories (Standard Probe, Depth Probe, UIR, Microscope Frame, DRF). System tracks surgical tools during cranial and spinal procedures; replaces wired, powered accessories with passive-reflective markers. Used in OR by surgeons for preoperative and operative planning; workstation displays images to guide navigation. Passive markers reflect infrared signals to camera; system calculates tool position relative to patient anatomy. Facilitates surgical navigation in complex anatomical environments; improves targeting accuracy near critical structures.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Optical tracking system; uses NDI Polaris Camera for infrared signal detection. Accessories (probes, frames) equipped with passive reflective spheres. Replaces wired/powered tracking tools with passive-reflective markers. System integrates with OTS workstation for image-guided surgery. Intended for cranial and spinal applications.

Indications for Use

Indicated for cranial and spinal surgical procedures where anatomical landmarks are obscured or targets are near critical structures.

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.

Predicate Devices

• Radionics OTS (wired version)

## 5.0 510(k) Summary

## 510(k) Summary

This summary of 510(k) safety and effectiveness information is submitted in accordance with the requirements of the Safe Medical Devices Act of 1990 and 21 C.F.R. § 807.92.

1. The submitter of this premarket notification is:

Kevin O'Connell Regulatory Engineer Radionics Software Applications, Inc. 22 Terry Avenue Burlington, MA 01803 Tel: (781) 272 - 1233 Fax: (781) 272 - 2428

This summary was prepared on October 8, 1998.

2. This premarket notification describes a modification to the Radionics Optical Tracking System (OTS). The common name of this device is Intraoperative Guidance Device, and its classification name is Stereotaxic instrument.

3. The modification involves the use of a NDI Polaris Camera and the incorporation of reflective spheres to the Standard Probe, Depth Probe, UIR, Microscope Frame, and DRF accessories . These accessories are substantially equivalent to their wired counterparts in the predicate Radionics OTS.

4. When coupled with the OTS workstation and using the NDI Polaris Camera, the above reflective accessories function in the same way as the predicate wired versions by allowing preoperative and operative planning of cranial and spinal surgical procedures using workstation images.

5. Like their counterparts in the predicate Radionics OTS, the reflective based tools are intended to facilitate the preoperative and operative planning of cranial and spinal surgical procedures. There are no operational differences between the wired and reflective accessories. All phases of preoperative and operative planning remain unchanged.

6. Apart from the use of passive reflectance with the OTS tools, rather than an AC or DC power source, the technological characteristics are the same as or similar to, those of the predicate wired device where infrared signals are used to provide tracking information as an aid to cranial and spinal surgery.

Dear Mr. O'Connell:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
