Intended Use

The RF Tent is intended to create an area of substantially reduced Electromagnetic Interference (EMI) in the area enclosed by the RF Tent during image acquisition by the PoleStar N-10 (K002242).

Device Story

RF Tent serves as portable, conductive shielding accessory for PoleStar N-10 intraoperative MRI system; replaces fixed copper wall sheeting. Device creates enclosed area of reduced electromagnetic interference (EMI) to facilitate high-quality MR image acquisition. Used in operating rooms; allows PoleStar N-10 mobility between multiple ORs without requiring permanent room shielding. Healthcare providers deploy tent to isolate scanner from external EMI sources. Benefits include lower cost, elimination of lengthy room installation downtime, and increased operational flexibility for intraoperative imaging.

Clinical Evidence

Bench testing only. Performance data provided via Signal to Noise ratio results to demonstrate effective EMI attenuation comparable to fixed copper shielding.

Technological Characteristics

Portable conductive enclosure (RF Tent). Principle of operation: electromagnetic shielding via conductive material to attenuate external EMI. Designed for use with PoleStar N-10 MRI system. No software or active electronic components.

Indications for Use

Indicated for use in clinical environments requiring electromagnetic interference (EMI) reduction during image acquisition with the PoleStar N-10 intraoperative MRI system.

Regulatory Classification

Identification

A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).

Special Controls

*Classification.* Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device 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

# 510(k) Summary of Safety and Effectiveness

The following 510(k) Summary of Safety and Effectiveness has been prepared pursuant to requirements for 510(k) summaries specified in 21 CFR § 807.92(a).

# 807.92(a)(3) - Predicate Devices:

The RF Tent is a new accessory of the PoleStar N-10 Intraoperative Magnetic Resonance Device (K002242), but it can also be considered as a modification to the presently installed copper sheeting solution to create an area of substantially reduced Electromagnetic Interference (EMI) in the area enclosed by the RF Tent.

Image /page/1/Picture/0 description: The image shows the logo for Odin Medical Technologies. The word "odin" is written in bold, sans-serif font. Below the word "odin" is the phrase "Medical Technologies" in a smaller font. A circular graphic is to the right of the word "odin", with a small dot above the "i" in "odin".

# 807.92(a)(4) - Device Description:

To acquire high-quality MR images. it is necessary to isolate the MRI scanner from external sources of EMI (Electromagnetic Interference). Generally, copper sheeting is installed in the OR walls to isolate the OR from external interference. This solution is relatively expensive, and also requires the OR to be out of use during the installation process. Once the copper sheeting is installed, all procedures involving the PoleStar N-10 intraoperative MRI must be performed in the dedicated shielded room.

The RF Tent presented in this premarket notification expands the capability of the PoleStar N-10 (K002242), by providing a low cost, simple and effective alternative to the fixed copper shielding. Because it is portable, it also allows the PoleStar N-10 to be used in more than a single dedicated OR. Thereby increasing the flexibility of the use of the system.

## 807.92(a)(5) - Device Intended Use:

ないということでするとなってきませんですけど

The RF Tent is intended to create an area of substantially reduced Electromagnetic Interference (EMI) in the area enclosed by the RF Tent during image acquisition by the PoleStar N-10 (K002242).

# 807.92(a)(6) - Substantial Equivalence Comparison Table:

The RF Tent and the presently implemented installed copper sheeting have the same intended use; to create an area of substantially reduced Electromagnetic Interference (EMI) in the area enclosed by these means. Both solutions use conductive means to provide similar attenuation levels.

Odin RF Tent's intended use is similar to the presently implemented installed copper sheeting, with the following main advantages:

- . Initial Cost - The purchase and installation cost of the copper sheeting is approximately ten times more than the RF Cage.
- . Installation - Installation of copper sheeting requires the OR to be out of use for approximately three months. There is no installation required for the RF Tent.

The word "odin" is written in bold, sans-serif font, with "Medical Technologies" written in a smaller font size below it. A stylized graphic of a circle with a dot on top is to the right of the word "odin."

- Dedicated OR Because the RF is portable, the PoleStar N-10 does . not have to be used in a dedicated OR.
## Performance Data:

Substantial equivalence was based on performance data. Signal to Noise results are provided in Attachment 2 of the 510(k) submission.

## Conclusions:

The RF Tent adressed in this premarket notification, has the same intended use and technological basis as the presently implemented installed copper sheeting used with the legally marketed Intraoperative Magnetic Resonance Device PoleStar N-10 (K002242). Based on the analysis and tests performed by Odin Medical Technologies regarding the proper function of the RF Tent. We believe that the RF Tent can be safely and effectively used.
