Intended Use

The Medtronic MR8 Drill System is indicated for the incision/cutting, removal, drilling, and sawing of soft and hard tissue, bone, and biomaterials in Neurosurgical (Craniofacial including craniotomy); Ear, Nose and Throat (ENT), Maxillofacial, Orthopedic, Arthroscopic, Spinal, Sternotomy, and General Surgical Procedures.

Device Story

MR8 Drill System comprises electric and pneumatic handpieces, attachments, and surgical dissecting tools. System uses electric or pneumatic energy to power interchangeable dissecting tools for cutting, drilling, or sawing bone and soft tissue. Used in OR settings by surgeons across various specialties (neurosurgery, ENT, orthopedics, etc.). Handpieces and attachments are reusable; dissecting tools are single-use sterile. Device provides mechanical power to tools, allowing surgeons to perform precise tissue removal. Benefits include improved performance and efficiency over predicate systems. Healthcare providers operate the device manually to facilitate surgical access or bone resection.

Clinical Evidence

Bench testing only. Performance testing included motor speed/torque analysis, cutting performance (tool chatter and vibration), electrical safety (IEC 60601-1:2005), and electromagnetic compatibility (IEC 60601-1-2:2014). Cadaveric simulated use study confirmed acceptability for intended surgical procedures.

Technological Characteristics

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

- Midas Rex Legend EHS Electric Drill System (K081475)

{4}------------------------------------------------

- Midas Rex MR7 Pneumatic High Speed System (K090112) ●
- Midas Rex Legend System (K020069)

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

The currently available Midas Rex Drill System consists of pneumatic and electric handpieces, attachments, surgical dissecting tools, and system accessories. The subject drill system remains similar to the predicate drill system in terms of operating principles, where air and/or electric energy is supplied to the handpiece to provide power to operate interchangeable Surgical Dissecting Tools supported by Attachments and intended for use in various surgical procedures to remove soft and hard tissue, bone, and biomaterials. The materials used in design and manufacturing of the drill system remain similar to those of the predicate drill system. Minor design changes were made to the electric/pneumatic handpieces and the attachments to both improve the performance/efficiency of the drill system. None of the changes to the system impact safety and effectiveness or its ability to perform to its intended use as a drill system.

#### XI. Discussion of the Performance Testing

Testing was completed to ensure the functionality of the new drill system. The following table summarizes the performance testing completed:

| Test | Description | Results |
|-------------------------------------|-----------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------|
| Motor Speed/Torque<br>Analysis | Analyzed motor speed/torque profile in comparison to predicate devices | Speed/torque profile is similar to that of predicate Legend device |
| Drill System Cutting<br>Performance | Cutting performance was compared to predicate drill system in terms of tool chatter and hand vibration | Cutting performance was equivalent or better to that of predicate device |
| Electrical Safety | Electric powered instruments evaluated for electrical safety | Instruments conform to IEC 60601-1:2005 for electrical safety. |
| Electromagnetic<br>Compatibility | Electric powered instruments evaluated for electromagnetic compatibility | Instruments conform to IEC 60601-1-2:2014 for electromagnetic compatibility. |
| Cadaveric Simulated<br>Use | Users evaluated the acceptability of the subject drill system to its intended use on a variety of procedures using cadavers | MR8 Drill System acceptable for its intended use in various surgical procedures |

#### XII. Conclusions

The MR8 Drill System has been shown through comparison and testing to be substantially equivalent to the identified predicate devices.
