## PREDICATE DEVICE

K202635 MY01 Continuous Compartmental Pressure Monitor

# DEVICE DESCRIPTION

The MY01 Continuous Compartmental Pressure Monitor (MY01 device) is a device for measuring real-time and continuous compartmental pressured compartmental pressures should always be used along with the current standard of care as an aid in the diagnosis of compartment syndrome.

The device is supplied sterile for single patient use and intended to be used for 18 hours, it contains two major components that are referred to as the Introducer (plastic housing and 17- gauge stainless-steel needle) and the Pressure Monitor. The Pressure Monitor consists of a capacitive Micro-Electro-Mechanical System (MEMS) pressure sensor, which allows for the measurement of intracompartmental pressure relative to a secondary atmospheric pressure sensor.It is embedded on a flexible PCB circuit, which extends via a lead-wire to a rigid PCB circuit within the Pressure Monitor. The Introducer allows for placement of the pressure sensor into muscle compartments. The Pressure Monitor continuously outputs pressure values on the LCD screen and can be attached on the patient's skin using the provided adhesive strip on the underside.

MY01 device uses wireless communication over BLE to transmit data to an optional, nongeneric compatible accessory mobile application, which is also developed by MY01 Inc. for data logging and archival purposes and both cleared under Traditional 510(k), K202635.

The MY01 Mobile Application cleared under K202635 is a Non-Device MDDS as per FDA guidance documents "Policy for Device Software Functions and Mobile Medical Applications" and "Medical Device Data Systems, Medical Image Storage Devices, and Medical Image Communications Devices" (both issued on September 27, 2019) and is therefore not subject to FDA regulatory requirements applicable to devices.

### Modification:

The modification that necessitated this submission entails the addition of a graphing feature to the accessory MY01 Mobile Application cleared for the same manufacturer, MY01 Inc., under premarket notification K202635. The added graphing feature to the accessory MY01 Mobile Application is for informational purposes only and is not intended for active patient monitoring or diagnosis.

MY01 Inc. intends to release MY01 Mobile Application with an option to display the recorded pressure data either as displayed on the MY01 device itself or as a graph that is updated in realtime. This MY01 Mobile Application release shall replace the MY01 Mobile Application cleared under the predicate device (K202635). Authenticated users of the Mobile Application can

{5}------------------------------------------------

securely connect to a MY01 device which enables the transmission of pressure data via an encrypted BLE link. The current pressure data measurement is displayed on the application and forwarded via an encrypted network link to a cloud-based server (MY01 Application Server) for data logging and archival purposes. The optional graphical display option does not alter, interpret, or analyze the MY01 device data. The MY01 Mobile Application does not control the functions or parameters of the MY01 device in any way. The graphical display option offers physicians visual cues on sudden excursions in real-time. Such events may, for example, relate to the patient's physical movement, adjusting of bandages or cast around the limb rather than the clinical condition. The graph will therefore help physicians in taking note of such events (e.g. on patient records). The displayed and recorded graph is intended for informational purposes only and is not to be used for active-patient monitoring or diagnostic purposes, as indicated in the MY01 device and MY01 Mobile Application User Manuals, Therefore, the graphing feature does not alter the intended use of the MY01 device. Data collected from graph is archived on the same cloud database as the raw recorded pressure data and can be reviewed at a later time.

# INTENDED USE/INDICATIONS FOR USE
