No
The document describes a standard electric surgical motor and its accessories, with no mention of AI or ML capabilities in its function, control, or data processing.
Yes
The device is intended for use in surgical procedures for cutting, drilling, reaming, decorticating, shaping, and smoothing of bone, bone cement, and teeth, directly impacting the body for therapeutic purposes.
No
This device is described as a motor intended for cutting, drilling, reaming, decorticating, shaping, and smoothing of bone, bone cement, and teeth during various surgical procedures. It is an operative tool, not a diagnostic one.
No
The device description clearly describes a physical, electric-powered motor with an aluminum body, cord, and connections to a console and foot switch/handswitch. It is a hardware device used for surgical procedures.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The description clearly states the device is a motor used for cutting, drilling, reaming, shaping, and smoothing bone, bone cement, and teeth during surgical procedures. It also mentions its use with screws, metals, wires, pins, and other fixation devices.
- Intended Use: The intended use is directly related to surgical intervention on the body, not the analysis of specimens taken from the body.
- Lack of IVD Indicators: The text does not mention any analysis of biological samples, diagnostic purposes based on sample analysis, or any components typically associated with IVD devices (reagents, calibrators, controls, etc.).
Therefore, the Pi Drive 2 and Pi Drive 2 Plus Motors are surgical tools, not In Vitro Diagnostic devices.

Device Description
The Pi Drive 2 and Pi Drive 2 Plus Motors are non-patient contact, reusable, electric powered (40 VDC) motors that are supplied non-sterile and intended to be to be sterilized by the user prior to each use. The devices are driven by a three-phase, four-pole, brushless DC motor that is housed in a black anodized aluminum body and directly rotates cutting accessories up to speeds of 75,000 RPM. A 4.6 m long cord is integrated into the proximal end of each motor which is used to connect directly to the CORE 2 Console.
The CORE 2 Console is used to supply power to the motors and in conjunction with a foot switch (connected to the console) is used for motor activation and speed control. The Pi Drive 2 Plus contains circuitry that also allows it to be operated using a Stryker handswitch for activation and speed control.
Both motors are identical in technology, functionality, indications for use, and are compatible with the same attachments and cutting accessories. The Pi Drive 2 Plus motor is approximately 10.3 mm longer and weighs 85 grams more than the Pi Drive 2 motor, this additional length accommodates use of the Stryker handswitch.

Dear John Chesney:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies.combination product submissions. 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.
