Intended 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 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 accurately shape a rod for use in spinal surgery applications. The Bendini Spinal Rod Bending System shares the following components with the predicate device: a computer with touch screen display, a 6DOF optical and electromagnetic localizer system, and localized pointers or styluses 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.
More Information

Not Found

No
The description mentions "a proprietary set of algorithms" but provides no indication of AI/ML techniques being used. The performance studies focus on accuracy and equivalence to a predicate device, not on AI/ML specific metrics or training/testing data.

No
The device aids a surgeon in shaping a spinal rod for implantation, but it does not directly treat or diagnose a medical condition itself. It's a tool for preparing an implant, not a therapeutic device.

No

Explanation: The device is described as a system used to locate spinal implant system instrumentation and generate bend instructions for shaping a spinal rod. It aids in the mechanical bending of a rod, which is a therapeutic intervention, not a diagnostic one. While it acquires data about the relative location of anatomical landmarks, this data is used for surgical planning and execution (shaping a rod), not for identifying a disease, condition, or anomaly.

No

The device description explicitly lists hardware components like a computer with a touch screen display, a 6DOF optical and electromagnetic localizer system, and localized pointers or styluses, indicating it is not solely software.

Based on the provided information, the Bendini™ Spinal Rod Bending System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is to locate spinal implant instrumentation and generate bend instructions for shaping a spinal rod for use in surgery. This is a surgical planning and execution tool, not a diagnostic test performed on biological samples.
  • Device Description: The device uses optical and electromagnetic localization to determine the relative location of surgical implants and anatomical landmarks. It processes this spatial data to generate instructions for a mechanical rod bender. This process does not involve analyzing biological samples to diagnose a condition or provide information about a patient's health status.
  • Lack of IVD Characteristics: The description does not mention any analysis of blood, tissue, urine, or any other biological sample. It focuses on spatial measurements and mechanical manipulation.

In summary, the Bendini™ Spinal Rod Bending System is a surgical planning and assistance device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

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, verification of software algorithms, and cadaver testing to demonstrate performance under anticipated clinical settings.

The results of the studies performed demonstrate 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.

The Bendini Spinal Rod Bending System shares the following components with the predicate device: a computer with touch screen display, a 6DOF optical and electromagnetic localizer system, and localized pointers or styluses 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 Bendini Spinal Rod Bending System and the predicate device is that the Bendini Spinal Rod Bending System does not integrate or overlay acquired data into patient data contained in radiographic images nor is it used to generate surgical intervention plans/approaches based on traiectories and/or other identified anatomical structures observed in radiographic images. 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, verification of software algorithms, and cadaver testing to demonstrate performance under anticipated clinical settings.

The results of the studies performed demonstrate 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.

H. Conclusions

Based on the indications for use, technological characteristics, performance testing, and comparison to a predicate device, the subject Bendini Spinal Rod Bending System has been shown to be substantially equivalent to a legally marketed predicate device.
