Device Facts

• Record ID: K160713
• Device Name: Stealth-Midas System
• Applicant: Medtronic Powered Surgical Solutions
• Product Code: OLO · Neurology
• Decision Date: May 26, 2016
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 882.4560
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Stealth-Midas System is indicated for the drilling, burring and removal of hard tissue and bone in spinal surgical procedures. Computer-assisted surgery and its associated applications are intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. Their use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as a long bone, or vertebra, can be identified relative to a CT- or MR-based model, fluoroscopic images, or digitized landmarks of the anatomy.

Device Story

Stealth-Midas System comprises electric and pneumatic surgical drill handpieces integrated with passive optical navigation trackers. Designed for use with the Medtronic StealthStation System, the device enables real-time navigation of surgical dissecting tools during spinal procedures. The system incorporates a secondary lock mechanism to ensure the dissecting tool remains fixed relative to the optical tracker, maintaining navigational accuracy. Operated by surgeons in an OR setting, the device provides visual feedback via the navigation system, allowing precise localization of anatomical structures relative to pre-operative or intra-operative imaging (CT, MR, fluoroscopy). This integration assists surgeons in navigating complex spinal anatomy, potentially improving surgical accuracy and patient outcomes by facilitating precise bone removal and tissue dissection.

Clinical Evidence

No clinical data. Evidence consists of bench testing, including navigation accuracy analysis, CAD model evaluation, and formative usability testing to confirm workflow and assembly.

Technological Characteristics

System consists of electric and pneumatic drill handpieces with integrated passive optical trackers. Features a secondary lock mechanism to secure dissecting tools. Compatible with Medtronic StealthStation navigation. Reusable, non-sterile delivery. Technology relies on optical tracking for spatial localization relative to anatomical models (CT/MR/fluoroscopy).

Indications for Use

Indicated for patients undergoing spinal surgical procedures requiring drilling, burring, or removal of hard tissue and bone where stereotactic surgery is appropriate and anatomical structures can be referenced to CT, MR, fluoroscopic, or digitized landmarks.

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.

- I. Company: Medtronic Powered Surgical Solutions 4620 North Beach St. Fort Worth, TX 76137 Telephone Number: [phone]
- Contact: John Connor Senior Regulatory Affairs Specialist Telephone number: [phone] Fax: [phone] Email: [e-mail]
- II. Proprietary Trade Name: Stealth-Midas System
- III. Common Name: Orthopedic Stereotaxic Instrument
- IV. Classification Name: Stereotaxic Instrument (21 CFR 882.4560)
- V. Classification: Class II
- Product Code: OLO VI.

#### VII. Product Description:

The Stealth-Midas System consists of electric and pneumatic drill handpieces that feature an optical navigation tracker, enabling navigation with the StealthStation System. The system allows the navigation of a selection of currently available surgical dissecting tools. The navigated handpieces are provided non-sterile and are reusable.

#### VIII. Indications for Use:

The Stealth-Midas System is indicated for the drilling, burring and removal of hard tissue and bone in spinal surgical procedures. Computer-assisted surgery and its associated applications are intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. Their use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as a long bone, or vertebra, can be identified relative to a CTor MR-based model, fluoroscopic images, or digitized landmarks of the anatomy.

#### IX. Identification of Legally Marketed Devices (Predicate Devices)

- Midas Rex Electric Surgical Drill/Saw System (K081475) ●
- . Midas Rex MR7 Pneumatic High Speed System (K090112)
- Navigated VERTEX SELECT® Instruments (K143628)

#### X. Comparison of the Technological Characteristics:

The currently available Midas Rex Drill System consists of pneumatic and electric handpieces, attachments, and surgical dissecting tools. There are no changes to any of the attachments or surgical dissecting tools. The only significant difference between the subject navigated handpieces and the currently available handpieces is the addition of a passive optical tracker to the hind to enable navigation of a selection of dissecting tools, and a secondary lock to eliminate any motion of the dissecting tool relative to the optical tracker. The addition of a tracker does not impact the ability of the drill system to perform to their intended use as a drill system.

The passive optical tracking technology is identical to that employed in the use of the predicate navigated Vertex Select instruments. Navigational accuracy testing confirms that the subject navigated drill system is as accurate as the predicate navigated Vertex Select instruments.

#### XI. Discussion of the Performance Testing

Testing was completed to ensure the functionality and compatibility with the identified Medtronic products. The following table summarizes the performance testing completed:

| Test | Description |
|---------------------------------|--------------------------------------------------------------------------------------|
| Navigation Accuracy<br>Analysis | Confirmed navigated instrument accuracy |
| CAD Model Evaluation | Verified that the CAD models are accurately<br>reflected in the application software |
| Formative Usability | Confirmed users can follow the navigated<br>workflow and assemble the device |

#### XII. Conclusions

The Stealth-Midas System has been shown through comparison and testing to be substantially equivalent to the identified predicate devices.
