The description focuses on locating implants and generating bend instructions based on their relative positions, which appears to be a deterministic process rather than involving AI/ML. There are no mentions of AI, ML, or related concepts like training or test sets.
No
The device aids in shaping spinal rods, which are instruments used in spinal surgery, but it does not directly treat or diagnose a disease or condition in a patient. It is a tool for a surgeon.
No
The device is used to generate bend instructions for a spinal rod based on the location of existing spinal implants, which is a planning and fabrication task rather than diagnosing a medical condition.
No
The device description explicitly states that the system consists of instruments (hardware) and software components, and lists three main components including an IR Stylus and a Mechanical Rod Bender tool, which are hardware.
Based on the provided information, the Bendini Spinal Rod Bending System 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, tissue) to provide information for diagnosis, monitoring, or screening.
- Bendini System Function: The Bendini System's intended use and description clearly state that it is used to locate spinal implant instrumentation within the body and generate instructions for bending a spinal rod for use in surgery. It does not analyze biological specimens.
- Lack of IVD Characteristics: The description does not mention any analysis of biological samples, laboratory procedures, or diagnostic information derived from bodily fluids or tissues.
The Bendini System is a surgical planning and assistance tool used in vivo (within the living body) to aid in the surgical procedure of spinal rod bending.
N/A
Intended Use / Indications for Use
The Bendini Spinal Rod Bending System is used to locate spinal implant system instrumentation (screws, hooks) to determine their relative location to one another to generate bend instructions to shape a spinal rod. A surgeon is able to use those instructions and bend a rod using the Bendini Bender, a mechanical rod bender.

Device Description
The NuVasive Bendini Spinal Rod Bending System consists of instruments (manufactured from stainless steel and polycarbonate) and software components that are used to locate spinal implant system instrumentation (screws, hooks), determine their relative location to one another, and generate bend instructions that are used along with the Bendini bender to shape a rod for use in spinal surgery applications.
The Bendini System consists of three main components:
- IR Stylus composed of a sterile handle with integrated IR markers, and non-sterile shaft options (solid or offset), that helps obtain the location of the implants,
- Software provided on a Bendini System control unit, converts the implant locations to a series of bend instructions, and
- Mechanical Rod Bender tool used by the surgeon to execute the bend instructions.

Summary of Performance Studies
Nonclinical testing was performed to demonstrate that the Bendini Spinal Rod Bending System is substantially equivalent to a predicate device. This testing performed was determined to be necessary in establishing substantial equivalence and included evaluation of software performance per predetermined specifications outlined in the SRS, GUI functionality, error handling, system accuracy during data acquisition, verification of instrument performance in combination with the software, and verification of software algorithms using anatomical models.
The results of the studies performed show that the subject Bendini Spinal Rod Bending System meets the performance of the predicate device, and the subject device was therefore found to be substantially equivalent.

rod using the Bendini Bender, a mechanical rod bender.
F. Technological Characteristics
As was established in this submission, the subject Bendini Spinal Rod Bending System is substantially equivalent to a predicate device cleared by the FDA for commercial distribution in the United States.
The Bendini Spinal Rod Bending System shares the following components with the predicate device: a computer with touch screen display, a six (6) DOF optical localizer system, and localized pointers or stylus used to digitize intraoperative anatomical landmarks. Both the Bendini Spinal Rod Bending System and the predicate device intraoperatively digitize the relative location of anatomical landmarks with a localized pointer or stylus in order to acquire data that is then interpreted by a proprietary set of algorithms.
The main technological differences between the subject Bendini Spinal Rod Bending System and the predicate device, K111811, are the following:
- . Bendini IR Stylus Handle - modification to incorporate integrated reflective IR markers in a preassembled, sterile, single-use configuration for ease of use. The IR markers used in the predicate Bendini Stylus referenced in 510(k) K111811 were off-the-shelf components.
- Bendini IR Stylus Shaft modification to a detachable design that attaches to the IR . Stylus Handle, and can extend by 2mm increments to add an offset distance to a desired acquisition point.
Any differences in technology do not raise questions or issues regarding safety and effectiveness of the Bendini Spinal Rod Bending System.
Based on the comparison above, the subject device was shown to be substantially equivalent and have the same technological characteristics to its predicate device in areas including design, intended use, material composition, and function.
G. Performance Data
Nonclinical testing was performed to demonstrate that the Bendini Spinal Rod Bending System is substantially equivalent to a predicate device. This testing performed was determined to be necessary in establishing substantial equivalence and included evaluation of software performance per predetermined specifications outlined in the SRS, GUI functionality, error handling, system accuracy during data acquisition, verification of instrument performance in combination with the software, and verification of software algorithms using anatomical models.
The results of the studies performed show that the subject Bendini Spinal Rod Bending System meets the performance of the predicate device, and the subject device was therefore found to be substantially equivalent.
