The document describes a computer-assisted surgical navigation system that uses tracking software and a camera to guide the surgeon. There is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies. The system appears to rely on established navigation and tracking algorithms rather than learning-based approaches.
No
The device is a surgical navigation system intended to assist surgeons in determining reference alignment axes and positioning orthopedic implant components, rather than directly treating a disease or condition.
Yes
The device aids the surgeon in performing "intra-operative measurements of leg length, offset, and cup inclination/anteversion," which are measurements used to inform surgical decisions and ensure proper implant positioning. This function aligns with the definition of a diagnostic device, as it provides information about the patient's condition (anatomical measurements) that is crucial for treatment planning.
No
The device description explicitly states that the system is comprised of hardware components including a handheld navigation device, computer, and camera, in addition to software.
Based on the provided information, the Naviswiss Hip Navigation System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Naviswiss Function: The Naviswiss Hip Navigation System is a surgical navigation system used during a surgical procedure (Total Hip Arthroplasty). It assists the surgeon in positioning implants and making measurements in vivo (within the living body), not by analyzing samples in vitro (outside the body).
- Intended Use: The intended use clearly states it's for assisting the surgeon in determining reference alignment axes and aiding in the positioning of orthopedic implant components. This is a surgical aid, not a diagnostic test performed on a specimen.
Therefore, the Naviswiss Hip Navigation System falls under the category of a surgical navigation system or computer-assisted surgical system, not an IVD.
N/A
Intended Use / Indications for Use
The Naviswiss Hip Navigation System is a computer-controlled system intended to assist the surgeon in determining reference alignment axes to aid in the positioning of orthopedic implant system components where a reference to a rigid anatomical structure can be identified. The system is only compatible with acetabular cup impactors that have a parallel and straight segment. The system aids the surgeon in performing intra-operative measurements of leg length, offset, and cup inclination/anteversion.
An example of a stereotaxic orthopedic surgical procedure includes Total Hip Arthroplasty: Lateral/Supine.
The equipment is intended for use by trained surgeons in operating theaters.

Device Description
The Naviswiss Hip Navigation System is an image-free surgical navigation system intended to assist the orthopedic surgeon during the implantation of an artificial joint (hip). The device consists of a handheld navigation device, used to register the patient's anatomy into a software platform. Subsequently the navigation system helps the surgeon maneuver the surgical instruments with precision. Thus, the surgeon can position the implant in accordance to pre-operative planning.
The Naviswiss Hip Navigation System is comprised of two major sub-systems: the Naviswiss Hip (M42) and Naviswiss Platform (M59).
The Naviswiss Hip (M42) is composed of:
- . NAVItags used for reference and registration
- . Ancillary instruments
- . Application Software
The Naviswiss Platform (M59) is composed of:
- . Computer
- Camera ●
- . Software
The M42 employs the base computing, power supply, and programing in the M59 Platform. The NAVItags allow the surgeon to determine anatomical landmarks or navigate an instrument.
The camera utilizes application and tracking software to guide the surgeon through a workflow process for the surgery. The camera is covered by a sterile, single use drape for use of the navigation device in a sterile environment.

Summary of Performance Studies
System Accuracy:
The Naviswiss Hip Navigation System's accuracy was verified according to the methodology in ASTM F2554-18 - Standard Practice for Measurement of Positional Accuracy of Computer Assisted Surgical Systems. Testing simulated normal conditions, and a variety of worst-case use scenarios and realistic tracking disturbances. All requirements were met.
Benchtop Accuracy:
The Naviswiss Hip Navigation System's accuracy was verified using calibrated test fixtures. All requirements were met.
Anatomical Phantom Simulated Use and Clinical Accuracy:
Simulated use testing was performed on a metallic bone simulator by orthopedic surgeons in THA procedures following a typical workflow. The test validated that the Naviswiss Hip Navigation System satisfies user needs, intended use, and clinical accuracy requirements. This was assessed by comparing the measurements obtained in the simulated use with known values.
Cadaver Simulated Use:
Simulated use testing was performed in multiple cadaver wet labs to validate the Naviswiss Hip Navigation System satisfies clinical use requirements and performed as intended on human specimans when used in an OR environment by trained surgeons.
OUS Prospective Clinical Study:
Naviswiss is conducting a prospective clinical study in Australia. The study was designed to evaluate 35 patients undergoing elective THA surgery. The primary outcome is the agreement between intraoperative component positioning data captured by the Naviswiss Hip Navigation System compared with post-operative CT measurements.

The technological principle for both the subject and predicate devices is to provide intra-operative measurements during orthopedic surgery. It is based on the use of infrared optical technology to provide real-time, intraoperative data on leg length, offset, and cup position.
The subject and selected predicate devices are based on similar technological elements. The system generates positional measurements between a camera and a tracker that can be mounted on different objects. The camera uses the application software and the tracking software to guide the surgeon through a workflow process for the surgery.
