Intended Use

The WatchPAT300 is a non-invasive home care device for use with patients suspected to have sleep related breathing disorders. The WP300 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 WP300 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 optional snoring level and body position discrete states from an external integrated snoring and body position sensor. The WP300's PSTAGES and snoring level and body position provide supplemental information to its PRD/PAHI/PAHIc. The WP300'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. PAHlc is indicated for use in patients 17 years and older. All other parameters are indicated for 12 years and older.

Device Story

WatchPAT300 (WP300) is a wrist-worn, non-invasive home-use diagnostic aid for sleep-related breathing disorders. Inputs include peripheral arterial tonometry (PAT) signals and blood oxygen saturation from a finger-mounted uPAT probe, plus wrist motion from an embedded actigraph and optional chest movement sensor. Device records data during sleep; offline management software analyzes signals to calculate respiratory indices (pRDI, pAHI, pAHIc), sleep stages (pSTAGES), snoring levels, and body position. Software includes an arrhythmia flagging feature (inherited from WP200U) to identify suspected atrial fibrillation and premature beats. Output is provided to physicians to supplement clinical history and diagnostic information; not intended as a primary diagnostic tool for cardiac arrhythmia or life-sustaining monitoring. Benefits include home-based screening for sleep disorders and supplemental cardiac rhythm flagging to guide further clinical investigation.

Clinical Evidence

Bench testing only. Verification and validation of software performed per FDA guidance. Bench testing confirmed equivalence of PAT and actigraphy signals between WP300 and WP200U, ensuring the arrhythmia algorithm receives equivalent input data.

Technological Characteristics

Ventilatory effort recorder using Peripheral Arterial Tone (PAT) signal. Components: wrist-worn control unit with OLED screen, uPAT finger probe, actigraph, optional chest sensor, and optional tamper-proof bracelet. Power: 1.5V AAA alkaline or 1.2V NiMH rechargeable battery. Sensing: optical plethysmography (oximetry), PAT, actigraphy. Connectivity: offline management software. Software: rule-based/algorithmic analysis for respiratory indices and arrhythmia flagging.

Indications for Use

Indicated for patients 12 years and older suspected of sleep-related breathing disorders; PAHIc parameter indicated for patients 17 years and older.

# Intended Use

The WatchPAT300 is a non-invasive home care device for use with patients suspected to have sleep related breathing disorders. The WP300 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 WP300 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 optional snoring level and body position discrete states from an external integrated snoring and body position sensor. The WP300's PSTAGES and snoring level and body position provide supplemental information to its PRD/PAHI/PAHIc. The WP300'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. PAHlc is indicated for use in patients 17 years and older. All other parameters are indicated for 12 years and older.

### Device Description

The subject WatchPAT300 (WP300) is identical in its intended use and indications for use to the cleared predicate WP200U (K203839) and the cleared predicate WP300 (K180775). The subject WP300 combines the software arrhythmia feature of the WP200U cleared predicate (K203839) into the WP300 cleared predicate (K180775).

The subject WP300 consists of: A wrist worn Control Unit, Actigraphy (in the Control Unit), Wrist Strap, Power Supply (battery), uPAT probe, Chest sensor (optional), Tamper-Proof Bracelet (optional), and Management and Analysis Software (SW).

The subject WP300, like the predicate WP200U and predicate WP300, uses the same offline Management and Analysis Software (SW). The arrhythmia feature is to be used for informational use only, to flag patients suspected of having arrhythmias, thereby aiding the physician to decide if further arrhythmia investigation is needed. The device is not intended to be used as a diagnostic device for cardiac arrhythmia and it is not intended to replace traditional methods of diagnosis. The arrhythmia detection is not intended for use in life supporting or sustaining systems or monitor and alarm devices. It provides the sleep physician with additional information to that of the WP300 cleared capabilities of detecting sleep disorders, to be considered in conjunction with the physician's knowledge of patient background, clinical history, symptoms, and other diagnostic information.

### Technological Characteristics

The subject WP300 has the same technological characteristics as the predicates WP300 and WP200U to which it has been modified.

Identically to WP200U and WP300, the subject WP300 device is a ventilatory effort recorder that utilizes Peripheral Arterial Tone (PAT) signal. It is a patient-worn device used at home for aiding in the diagnosis of sleep related breathing disorders based on the PAT signal. In all 3 systems, the controller part of the device is worn on the wrist and records the PAT signal and blood oxygen saturation levels in the distal part of the finger-mounted probe based on an optical plethysmographic method, and the wrist motion from an embedded actigraphy. The following report output information is provided by the cleared WP200U, cleared WP300,

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

and the subject WP300 using the same offline SW and algorithms that analyze recorded data to present respiratory disturbance index (pRDI), Apnea Hypopnea Index (pAHI), Central Apnea Hypopnea Index (pAHIc), sleep stages (pSTAGES - REM Sleep, Light Sleep, Deep Sleep, Wake), snoring level and body position discrete states. The new arrhythmia information in the subject WP300's report is identical to the one in the cleared WP200U.

The subject WP300, identically to both predicates, consists of the same components: (1) Same unified PAT probe (uPAT) is used to measure the PAT and oximetry signals; (2) an embedded actigraph which provides a signal that is used to determine periods of sleep/wake based on the motion of the wrist: (3) Electronics, which include a microprocessor that records the information supplied by the uPAT finger probe, actigraph and chest movement; and (4) chest sensor (SBP/RESBP sensors same as in the predicates).

The SW characteristics of the subject WP300 and the predicate WP300 are the same except for the newly added SW algorithm that was cleared for use in the WP200U (K203839) to identify or 'flaq' the patient for further arrhythmia investigation (Atrial Fibrillation and Premature Beats). This additional SW algorithm is the proposed modification to the subject WP300.

The hardware (HW) of the subject WP300 is the same as the HW of the predicate WP300 (K180775). Further, the HW of the WP300 was designed to provide identical signals to that of the predicate WP200U. The differences in HW between the WP300 and the WP200U devices have been thoroughly discussed and found to be substantially equivalent in K180775.

The cleared arrhythmia SW alqorithm from the predicate WP200U added to the subject WP300 does not alter the technological characteristics of the device or its principles of operation.

# Performance Data

SW verification and validation was performed on the subject WP300 device with the SW containing the additional arrhythmia feature as per the FDA guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". The testing and acceptance criteria are the same as those in the predicate devices. Bench testing was previously conducted on the predicate WP300 (in K180775) to show that the acquisition system of the WP300 and WP200U are generating the same input signals to the analysis algorithms. Specifically, the equivalence of the PAT and the actigraphy signals which are used in the newly added arrhythmia algorithm were tested. This testing provides evidence that the WP300 signals are equivalent to the WP200U signals.

# Substantial Equivalence

The subject WP300 has the same intended use as both previously cleared predicate devices, WP300 and WP200U. The WP300's new SW arrhythmia feature is offered as supplemental information to its sleep information. The device is not intended to be used as a diagnostic device for any cardiac arrhythmia. All other information supplied is the same as the information supplied by the predicate device and the differences in HW between the WP200U (in which the new SW feature for Arrhythmia detection was cleared) and the subject WP300 do not raise new questions of safety or effectiveness.
