## Indications for Use

The device is intended to provide physicians with tools for electromagnetic tracking of instruments with respect to image data. The device is available in two models 0.55mm and 0.9mm in diameter.

## Device Story

SonixGPS™ Needle Sensor is an electromagnetic tracking device used in hospital settings by physicians. It consists of a sensor head containing coils, a cable, and a connector. The device is placed inside a tracked instrument and operates within an electromagnetic field to detect the instrument's real-time position and orientation. This spatial data is integrated with ultrasound imaging to assist in navigating instruments through delicate anatomy to a target center. By monitoring the instrument's trajectory, the device enables precise placement during procedures. The output is visualized by the physician to guide clinical decision-making, potentially improving procedural accuracy and patient outcomes.

## Clinical Evidence

Bench testing only. Accuracy performance was verified using the Sonix 3D Motion Tracking protocol, comparing the 0.9mm and 0.55mm sensors against the predicate device. Results demonstrated equivalent performance meeting all defined accuracy criteria. Biocompatibility was confirmed per ISO 10993-1:2009, and electrical safety/EMC testing met EN 60601-1 and IEC 60601-1-2 standards.

## Technological Characteristics

Electromagnetic sensor assembly comprising a sensor head (polyimide tubing with internal coils), medical-grade PVC cable, and metal shell connector. Dimensions: 0.55mm or 0.9mm diameter; 96.8mm or 110.0mm length. Operates via electromagnetic field tracking. Non-sterile, reusable device. Complies with EN 60601-1 (electrical safety), IEC 60601-1-2 (EMC), and ISO 10993-1 (biocompatibility).

## Regulatory Identification

An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Special Controls

*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

## Predicate Devices

- Electromagnetic Tracking System ([K092619](/device/K092619.md))

Image /page/1/Picture/0 description: The image shows a logo for Ultrasonix. The logo consists of the word "ULTRASONIX" in a bold, sans-serif font, with a series of concentric circles made of dots surrounding the text. The dots are arranged in three rings, with the innermost ring having the fewest dots and the outermost ring having the most dots.

#### IV. Description of the Device -

The SonixGPS™ Needle Sensor is an electromagnetic sensor that is placed inside a tracked instrument and used within an electromagnetic field. The position and orientation can be detected and combined with the acquired imaging to assist with navigation of the tracked instrument. The needle sensor allows physicians the precise placement of instruments during each procedure by monitoring the real-time trajectory of the instrument as it advances through delicate anatomy to the center of a target.

The needle sensor consists of a sensor head, cable and a connector:

Connector is a positive latching, user-removable interconnect that conducts sensor data from the Cable to the electronics unit.

Cable is the wiring harness for the sensor that conducts sensor data from the Sensor Head to the Connector.

Sensor Head contains a set of coils that make up the measuring element of the sensor assembly.

#### V. Indications for Use of the Device

The device is intended to provide physicians with tools for electromagnetic tracking of instruments with respect to image data. The device is available in two models 0.55mm and 0.9mm in diameter.

#### Technological Characteristics VI.

The SonixGPS "" Needle Sensor has similar construction, manufacturing materials, operating principals and specifications as the predicate device.

Dear Mr. Sammons:

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. 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.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
