Intended Use

Pulse Navigation is intended as an intraoperative image-guided localization system in either open or minimally invasive spinal surgical procedures. Instruments and implants tracked by a passive marker sensor system are virtually displayed on a patient's 3D radiographic image data. The system enables computer-assisted navigation for spinal surgical procedures in which the use of stereotactic surgery may be appropriate and where a reference to a rigid anatomical structure can be identified relative to the acquired image of the anatomy. This may include the following spinal implant procedures: - Pedicle Screw Placement (cervical, thoracic, lumbar) - Iliosacral screw placement

Device Story

Pulse Navigation system provides intraoperative image-guided localization for spinal surgery. System inputs include 3D radiographic image data (CT or Cone Beam CT) and real-time tracking of surgical instruments via passive marker sensors and an Infrared (IR) camera. The Pulse ICT Adapter allows integration of the Globus Medical ICT Registration Fixture with the Pulse system's articulating arm and bedrail clamp. The system transforms these inputs by superimposing tracked instrument positions onto registered 3D images, providing real-time trajectory and depth information to the surgeon. Used in OR settings by surgeons to assist in pedicle and iliosacral screw placement. Output is a visual display of instrument position relative to patient anatomy, aiding surgical precision and decision-making.

Clinical Evidence

Bench testing only. Verification and validation included non-clinical system, software, and instrument testing to confirm compliance with user needs and design inputs. Accuracy and usability were verified against ASTM F2554-10, IEC 62366:2020, and IEC 62304:2015 standards. Results demonstrated the system meets all acceptance criteria.

Technological Characteristics

Stereotaxic instrument using fiducial-based registration. Components include Pulse ICT Adapter, ExcelsiusGPS ICT Fixture, articulating arm, and bedrail clamp. Sensing principle: Infrared (IR) camera tracking of passive markers. Connectivity: Networked/integrated with surgical imaging systems. Software lifecycle: IEC 62304 compliant. Standards: ASTM F2554-10 (positional accuracy), IEC 62366 (usability).

Indications for Use

Indicated for patients undergoing open or minimally invasive spinal surgical procedures, including pedicle screw placement (cervical, thoracic, lumbar) and iliosacral screw placement, where stereotactic surgery and image-guided localization are appropriate.

Navigation by providing an additional patient reference hardware design option by attaching Globus Medical Intra-Op CT Fixture to the following: existing Articulating Arm and Bedrail Clamp. Despite the changes introduced to predicate Spinous Process Clamp (K210574), the subject device is substantially equivalent to the predicate as demonstration and validation testing performed using well established and previously cleared test methods.

The Pulse System is a medical device consisting of Pulse LessRay, and Pulse Navigation. The Pulse System hardware includes a control unit, as well as accompanying accessory components.

The Pulse NVM5 is a medical device that is intraoperative neurological monitoring and status assessment during spinal surgery. The device provides information directly to the surgeon, to help assess a patient's neurological status. The Pulse NVMS provides this information by electrically stimulating nerves via electrodes located on surgical accessories and monitoring electromyography (EMG), motor evoked potential (MEP) or somatosensory evoked potential (SSEP) responses of the muscle groups innervated by the nerves. Moreover, a Twitch Test ("Train of Four") function is utility of the nerve to respond, or contract, following four stimulation pulses to determine the presence of neuromuscular block.

Additionally, the Pulse NVM5 System includes a software function that measures spinal parameters and acquires the location of spinal implants (screws, hooks) to assist the surgeon in bendini). Lastry, the Pulse NVMS provides Remote Access in two pathways, Local Wireless Control and Remote Monitoring.

Pulse LessRay is a software application which can be interfaced to a fluoroscope with a video cable. The images produced by the fluoroscope are transmitted to a frame grabber in the computer running LessRay where the images are enhanced and then displayed. When used in connection with the low dose and/or pulse setting on the fluoroscope, the user can improve the quality (clarity, contrast, noise level, and usability) of a noisy (low-quality) image. Using this system, much of the graininess of low radiation dose images can be eliminated. This allows for greater utility of low dose imaging. LessRay provides the additional feature of being able to interface LessRay with a tracking system in order to aid the C-arm technician in positioning the fluoroscope between the various views of the patient necessary for the intervention. LessRay with Tracking ensures that the fluoroscope is centered over the correct anatomy prior to taking any additional x-ray images.

Pulse Navigation is a stereotactic surgical as an aid for precisely locating anatomical structures in either open or percutaneous procedures. It is intended for intraoperative image-guided localization which allows for surgical instruments to be tracked in three-dimensional space. The device provides real-time information directly to the surgeon to evaluate

the instrument depth and trajectory for computer-assisted navigation during spine surgery. Instruments are tracked in threedimensional space with an Infrared (IR) Camera, being virtually displayed and superimposed on registered radiographic images. Radiographic images are in the form of 3D intraoperative scan (CT or Cone Beam CT).

The reason for the submission is to introduce a new intra-operative CT (ICT) adapter for use with the ExcelsiusGPS ICT Registation Fixture for the Pulse Navigation application.

#### E. Indications for Use

Pulse Navigation is intended as an intraoperative image-guided localization system in either open or minimally invasive spinal surgical procedures. Instruments and implants tracked by a passive mare virtually displayed on a patient's 3D radiographic image data. The system enables computer-assisted navigation for spinal surgical procedures in which the use of stereotactic surgery may be appropriate and where a reference to a rigid anatomical structure to the acquired image of the anatomy.

This may include the following spinal implant procedures:

- Pedicle Screw Placement (cervical, thoracic, lumbar)
- Iliosacral screw placement

#### F. Technological Characteristics

The introduction of new hardware (the Pulse ) and a new registration algorithm in software allows an updated fiducial-based patient registration method, when used together with ExcelsiusGPS ICT fixture. The subject device is comparable to the predicates in terms of intended use, fundamental scientific technological characteristics and principles of operation.
