Intended Use
The WatchPAT™ONE (WP1) device is a non-invasive home care device for use with patients suspected to have sleep related breathing disorders. The WP1 is a diagnostic aid for the detection of sleep related breathing disorders, sleep staging (Rapid Eye Movement (REM) Sleep, Light Sleep, Deep Sleep and Wake), snoring level and body position. The WP1 generates a peripheral arterial tonometry ("PAT") Respiratory Disturbance Index ("PRDI"), Apnea-Hypopnea index ("PAHI"), Central Apnea-Hypopnea index ("PAHIc"), PAT sleep staging identification (PSTAGES) and snoring level and body position discrete states from an external integrated snoring and body position sensor. The WP1's PSTAGES and snoring level and body position provide supplemental information to its PRDI/PAHI/PAHIc. The WP1's PSTAGES and snoring level and body position are not intended to be used as the sole or primary basis for diagnosing any sleep related breathing disorder, prescribing treatment, or determining whether additional diagnostic assessment is warranted. PAHIc is indicated for use in patients 17 years and older. All other parameters are indicated for 12 years and older.

The WP1 generates a PAT respiratory disturbance index (PRDI), Apnea Hypopnea Index (PAHI), Central Apnea Hypopnea Index (PAHIc), sleep stages (PSTAGES - REM Sleep, Light Sleep, Deep Sleep and Wake) and snoring level and body position discrete states. The WP1 device consists of the following: (1) same unified finger PAT probe that was used in WP300 to measure the PAT and oximeter signals; (2) same Actigraph which provides a signal that is used to determine periods of sleep/wake based on the motion of the wrist; (3) same electronics, except for an antenna added in the WP1's PCB to support BLE communication; (4) same chest sensor (RESBP) to measure snoring level, body position and chest movements; and (5) same zzzPAT Software and algorithm to analyze the data. The subject WP1 is a modified version of the predicate WP300 device (K180775). The proposed modifications mainly include: transition from a reusable device to a single use device; shifting the display and user interface from the device to a mobile application; and shifting of the data storage from main device to a web server.
More Information

Not Found

No
The summary does not mention AI or ML, and the device description focuses on hardware components and existing algorithms from a predicate device.

No.
The device is described as a diagnostic aid for detecting sleep-related breathing disorders and providing related measurements, not for treating any condition.

Yes
The "Intended Use / Indications for Use" section explicitly states, "The WP1 is a diagnostic aid for the detection of sleep related breathing disorders, sleep staging... snoring level and body position." This clearly indicates its role in diagnosing conditions.

No

The device description explicitly lists multiple hardware components: a finger PAT probe, Actigraph, electronics (including a PCB and antenna), and a chest sensor. While it utilizes software for analysis and a mobile application for display, it is fundamentally a hardware device with integrated software.

Based on the provided information, the WatchPAT™ONE (WP1) device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
  • WP1 Function: The WP1 device is a non-invasive home care device that measures physiological signals directly from the patient's body (PAT, oximetry, actigraphy, snoring, body position, chest movements) using external sensors. It analyzes these signals to provide diagnostic aid for sleep-related breathing disorders.
  • Lack of Specimen Analysis: The description does not mention the collection or analysis of any biological specimens from the patient.

Therefore, the WP1 falls under the category of a non-invasive diagnostic device rather than an In Vitro Diagnostic.

PAHIc is indicated for use in patients 17 years and older. All other parameters are indicated for 12 years and older.

5.14 Device Description:

The WatchPAT™ONE (WP1) is a non-invasive home care device intended for use with patients suspected to have sleep related breathing disorders. The WP1 generates a PAT respiratory disturbance index (PRDI), Apnea Hypopnea Index (PAHI), Central Apnea Hypopnea Index (PAHIc), sleep stages (PSTAGES - REM Sleep, Light Sleep, Deep Sleep and Wake) and snoring level and body position discrete states.

The WP1 device consists of the following: (1) same unified finger PAT probe that was used in WP300 to measure the PAT and oximeter signals; (2) same Actigraph which provides a signal that is used to determine periods of sleep/wake based on the motion of the wrist; (3) same electronics, except for an antenna added in the WP1's PCB to support BLE communication; (4) same chest sensor (RESBP) to measure snoring level, body position and chest movements; and (5) same zzzPAT Software and algorithm to analyze the data.

The subject WP1 is a modified version of the predicate WP300 device (K180775). The proposed modifications mainly include: transition from a reusable device to a single use device; shifting the display and user interface from the device to a mobile application; and shifting of the data storage from main device to a web server. None of these changes alter the fundamental technology or its principles of operation. Moreover, the WP1 maintains the same capabilities of the cleared WP300 (K180775) and provides the user with the same output information.

5.15 Substantial Equivalence:

Intended Use/Indications for Use

The subject device WP1 is identical to the cleared WP300 in its intended use and indications for use, except for the minor modification of omitting the word 'optional' from the use of snoring and body position sensor (RESBP sensor).

Comparison of Technological Characteristics and principle of operation

The technological characteristics and principles of operation of the subject device are similar to the predicate device. The subject WP1, like its predicate, is a ventilatory effort recorder that utilizes PAT technology. In both systems, the controller part of the device is worn on the wrist and records the PAT signal and blood oxygen saturation levels by a finger-mounted probe based on an optical plethysmographic method, the wrist motion from an embedded actigraphy and snoring level, body position states and chest movements from the chest sensor (RESBP).

5

The WP1 mainly differs from the WP300 by combining the key components into an undetachable monolith device. A mobile application also replaced the predicate WP300's user interface and communication. The WP1's monolithic package uses the same hardware as the predicate WP300 to measure patient data. In addition, the user interface of the mobile application was designed to provide similar display and input as the WP300. Although the patient data is transmitted and stored on a Web Server, the integrity of the patient data can be verified and validated. Furthermore, the cybersecurity risks were addressed according to FDA's cybersecurity guidance document'. As such, the differences in technological characteristics and principle of operation do not raise different questions of safety or effectiveness.

Performance Testing

The following consensus standards were used to evaluate the predicate device:

  • . Bench test was conducted to show that the data acquired on the WP1 is identical to the data downloaded by zzzPAT at the physician computer.
  • The WP1 was tested to ensure that the device complies with the Federal ● Communications Commission (FCC) rules.
  • Electrical safety testing per IEC 60601-1:2005 + CORR.1 (2006) + ● CORR.2 (2007) and AM1:2012
  • Electromagnetic compatibility testing per IEC 60601-1-2:2014
  • Home healthcare environment per 60601-1-11:2015
  • Cytotoxicity, irritation and sensitization testing of the new housing and wrist strap materials.
  • Software verification and validation testing was performed to demonstrate that the software in the subject device meets design specifications.

The testing above demonstrated that the WP1 has substantially equivalent performance as its predicate.

Summary

Based on the comparison of intended use, indications for use, technological characteristics and performance testing, Itamar Ltd. believes that the WP1 System is substantially equivalent to its predicate.

A summary of comparison between the subject and predicate devices is provided below.
