The document describes standard signal processing and analysis of physiological data (PAT, oximetry, actigraphy) to derive indices and sleep stages. There is no mention of AI, ML, or related concepts like training/test sets for algorithmic development.
No
The device is described as a "diagnostic aid for the detection of sleep related breathing disorders and sleep staging," indicating its purpose is to identify conditions rather than treat them.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The WP100S-2 is a diagnostic aid for the detection of sleep related breathing disorders and sleep staging."
No
The device description explicitly lists multiple hardware components including a finger PAT probe, a pulse oximeter, an actigraph, electronics, and a power supply, in addition to the device software.
Based on the provided information, the Watch-PAT100S-2 (WP100S-2) device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, to provide information for diagnostic, monitoring or compatibility purposes.
- WP100S-2 Function: The WP100S-2 is a non-invasive device that measures physiological signals directly from the patient's body (finger, wrist) using probes and sensors. It does not examine specimens derived from the human body in vitro.
- Intended Use: The intended use clearly states it's a "non-invasive home care device" and a "diagnostic aid" for detecting sleep related breathing disorders and sleep staging based on direct physiological measurements.
Therefore, the WP100S-2 falls under the category of a non-invasive diagnostic device rather than an In Vitro Diagnostic.

Intended Use / Indications for Use
The Watch-PAT100S-2 (WP100S-2) device is a non-invasive home care device for use with patients suspected to have sleep related breathing disorders. The WP100S-2 is a diagnostic aid for the detection of sleep related breathing disorders and sleep staging (Rapid Eye Movement (REM) Sleep, Light Sleep, Deep Sleep and Wake). The WP100S-2 generates a peripheral arterial tonometry ("PAT") Respiratory Disturbance Index ("PRDI"), Apnea-Hypopnea index ("PAHI") and PAT sleep staging identification (PSTAGES). The WP100S-2's PSTAGES provides supplemental information to its PRDI/PAHI. The WP100S-2's PSTAGES is 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.
The WP100S-2 is not indicated for children less than 17 years old.

Device Description
The WATCH-PAT100S-2 System (WP100S-2) is a non-invasive home care device for use with patients suspected to having sleep related breathing disorders. The WP100S-2 is a diagnostic aid for the detection of sleep related breathing disorders [Respiratory disturbance index (RDI), apnea hypopnea index (AHI)] and sleep staging (Rapid Eye Movement (REM) Sleep, Light Sleep, Deep Sleep and Wake) based on Peripheral Arterial Tonometry (PAT); a non-invasive technology.
The WP100S -2 device consists of: (1) a finger PAT probe, which is used to detect the PAT signal; (2) an embedded pulse oximeter using a second probe that is attached to another finger, for measuring blood oxygen saturation; (3) an embedded actigraph, which is used to determine periods of sleep based on the motion of the wrist; (4) Electronics, which include a controller that records the information supplied by the PAT finger probe, oximeter, and actigraph; (5) the device software; and (6) a power supply.
The device is worn on the wrist, and continuously measures the relative state of the vasomotor activity in the distal part of the finger, by a fingermounted probe based on a plethysmographic method. The measured signal is acquired from a self contained, opto-pneumatic sensor.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Software validation testing was conducted to evaluate both the performance of the WP100S-2 System and to verify that it performs according to its specifications described in the Software Requirements Specifications (SRS).
A clinical study was conducted to validate the accuracy of the WP100S-2 System in sleep staging identification and detection of respiratory related sleep disorders against both a gold-standard PSG and the predicate device (Biosleep for sleep staging identification and WP100S for respiratory disturbance index). The study results establish the accuracy of the WP100S-2 System in Sleep Staging identification. The study results additionally establish the accuracy of the WP100S-2 System in Sleep Apnea Indices (PRDI and PAHI).

5.14 Substantial Equivalence:
Intended Use
The intended use of the WP100S-2 is substantially equivalent to the combination of the intended use of its predicates and any minor differences do not alter the intended diagnostic value of the WP100S-2. The claim of sleep staging and breathing disorders indices, PRDI and its derivative PAHI, were supported by both software verification and validation activities and a clinical study.
Technological Characteristics and Mode of Operation
The WP100S-2, like its predicate the WP100S, is a ventilatory effort recorder that utilizes PAT technology. The hardware of the WP100S-2 is basically identical to that of the WP100S except that the internal coating of the WP100S-2's PAT probe was modified to a non-latex coating. The WP100S-2's software modifications raise no new issue of safety or effectiveness, as demonstrated through software verification and validation and supportive clinical data.
Performance Testing
Software validation testing was conducted to evaluate both the performance of the WP100S-2 System and to verify that it performs according to its specifications described in the Software Requirements Specifications (SRS).
A clinical study was conducted to validate the accuracy of the WP100S-2 System in sleep staging identification and detection of respiratory related sleep disorders against both a gold-standard PSG and the predicate device (Biosleep for sleep staging identification and WP100S for respiratory disturbance index). The study results establish the accuracy of the WP100S-2 System in Sleep Staging identification. The study results additionally establish the accuracy of the WP100S-2 System in Sleep Apnea Indices (PRDI and PAHI).
Summarv
Based on the performance testing results, including software verification and validation process and the analysis of the similarities and differences,
3
Itamar Ltd. believes that the WP100S-2 System is substantially equivalent to its predicates without raising new issues of safety or effectiveness.

Dear Mr. Kahan:
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 either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
