Intended Use
The iv Watch Model 400 is indicated for the detection of subcutaneous infiltrations and extravasations of 10 cc or less of optically clear, uncolored infusates, as an adjunctive device to the clinical evaluation in the hospital setting of patients 18 years old or greater with peripherally-inserted IVs (PIVs) on the forearm or dorsal aspect of the hand. The device is indicated to assess patients for subcutaneous infiltrations and extravasations but should not serve as a substitute for regular clinician assessment of the PIV site. The ivWatch Model 400 is intended for use by physicians, or under the direction of a physician, who have been trained in the use of the iv Watch Model 400.
Device Description
The ivWatch Model 400 is a medical device that provides continuous, noninvasive monitoring of human tissue adjacent to peripheral intravenous (PIV) insertion sites on the forearm and dorsal aspect of the hand to aid in the early detection of infiltration and extravasation events. The ivWatch Model 400 ("Device") consists of the ivWatch Patient Monitor (IPM), a reusable optical sensor cable, and a single-use sensor receptacle. The device uses visible and near-infrared light to measure changes in the optical properties of the tissue near a PIV insertion site; the measured changes are processed by proprietary ivWatch signal processing algorithms to determine if an infiltration event may have occurred. The device is indicated for use by medical professionals who are experienced with administering or monitoring peripheral IV therapy. The IPM mounts to an IV pole, typically above the infusion pump. The sensor is secured in the receptacle and subsequently placed on the patient's skin near the peripheral IV insertion site for the duration of the IV monitoring. The fiberoptic sensor cable follows the IV line back to the pole-mounted IPM. One end of the sensor cable attaches to the IPM; the other end snaps into the ivWatch sensor receptacle, which secures the sensor to the patient's skin. The sensor cable is a multiple-use disposable with a total useful life of approximately 240 hours of IV monitoring; it is intended to be cleaned between uses. The ivWatch sensor receptacle is molded out of biocompatible plastics and includes biocompatible adhesives for attaching the receptacle to the patient's skin. The sensor receptacle is a single-use disposable and supplied sterile. The IPM contains an optical system that generates light signals that are sent to the patient's skin (via the sensor cable) and measures the light returning from the patient's skin (also via the sensor cable). The Device uses low power LEDs as sources of visible and near-infrared (NIR) light. Optical fibers in the sensor cable deliver the light from the IPM to the sensor and transmit reflected light back to the IPM. The IPM also contains the hardware for executing the proprietary ivWatch signal processing algorithm. If changes in the optical properties of the tissue near the peripheral IV insertion site are consistent with an infusate pooling in the subcutaneous tissue, the IPM emits audible and visual notifications intended to prompt the clinician to inspect the peripheral IV site for a possible infiltration event.
More Information

No
The description mentions "proprietary ivWatch signal processing algorithms" but does not use terms like AI, ML, deep learning, or neural networks, which are typically associated with AI/ML technologies in regulatory submissions. The focus is on processing optical property changes, which can be achieved with traditional signal processing methods.

No
The device is indicated for the detection of subcutaneous infiltrations and extravasations, acting as an adjunctive device for assessment and alerting clinicians, not for direct treatment or therapy.

Yes
The device is indicated for "detection of subcutaneous infiltrations and extravasations" and uses measured changes to "determine if an infiltration event may have occurred," consistent with a diagnostic function.

No

The device description explicitly states it consists of hardware components: the ivWatch Patient Monitor (IPM), a reusable optical sensor cable, and a single-use sensor receptacle. It also describes the IPM containing an optical system and hardware for executing the algorithm.

Based on the provided information, the ivWatch Model 400 is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • ivWatch Model 400 Function: The ivWatch Model 400 is a non-invasive device that monitors human tissue in vivo (within the living body) using light. It does not collect or analyze specimens from the body. Its purpose is to detect changes in tissue properties that may indicate infiltration, not to analyze bodily fluids or tissues in vitro.

Therefore, the ivWatch Model 400 falls under the category of a non-invasive medical device used for monitoring, not an In Vitro Diagnostic device.

5.4 Device Description

The ivWatch Model 400 is a medical device that provides continuous, noninvasive monitoring of human tissue adjacent to peripheral intravenous (PIV) insertion sites on the forearm and dorsal aspect of the hand to aid in the early detection of infiltration and extravasation events. The ivWatch Model 400 ("Device") consists of the ivWatch Patient Monitor (IPM), a reusable optical sensor cable, and a single-use sensor receptacle.

The device uses visible and near-infrared light to measure changes in the optical properties of the tissue near a PIV insertion site; the measured changes are processed by proprietary ivWatch signal processing algorithms to determine if an infiltration event may have occurred. The device is indicated for use by medical professionals who are experienced with administering or monitoring peripheral IV therapy.

The IPM mounts to an IV pole, typically above the infusion pump. The sensor is secured in the receptacle and subsequently placed on the patient's skin near the peripheral IV insertion site for the duration of the IV monitoring. The fiberoptic sensor cable follows the IV line back to the pole-mounted IPM.

One end of the sensor cable attaches to the IPM; the other end snaps into the ivWatch sensor receptacle, which secures the sensor to the patient's skin. The sensor cable is a multiple-use disposable with a total useful life of approximately 240 hours of IV monitoring; it is intended to be cleaned between uses.

The ivWatch sensor receptacle is molded out of biocompatible plastics and includes biocompatible adhesives for attaching the receptacle to the patient's skin. The sensor receptacle is a single-use disposable and supplied sterile.

The IPM contains an optical system that generates light signals that are sent to the patient's skin (via the sensor cable) and measures the light returning from the patient's skin (also via the sensor cable). The Device uses low power LEDs as sources of visible and near-infrared (NIR) light. Optical fibers in the sensor cable deliver the light from the IPM to the sensor and transmit reflected light back to the IPM. The IPM also contains the hardware for executing the proprietary ivWatch signal processing algorithm.

If changes in the optical properties of the tissue near the peripheral IV insertion site are consistent with an infusate pooling in the subcutaneous tissue, the IPM emits audible and visual notifications intended to prompt the clinician to inspect the peripheral IV site for a possible infiltration event.

5.5 Indications For Use

The device is indicated to assess patients for subcutaneous infiltrations and extravasations but should not serve as a substitute for regular clinician assessment of the PIV site. The ivWatch Model 400 is intended for use by physicians, or under the direction of a physician, who have been trained in the use of the ivWatch Model 400.

5.6 Comparison of Technological Characteristics with the Predicate Device

At a high level, the subject device (ivWatch Model 400) and the predicate device (Baxter SIGMA Spectrum with Master Drug Library Model 35700) have the same intended use – ensuring the delivery of IV fluids to the patient's vein. The predicate device includes technology to detect fault conditions (air-in-line, upstream and downstream occlusions) which may prevent the IV fluid from being delivered to the intended administration route(s). The subject device is intended for use in detecting one particular fault condition (IV infiltration) that prevents the IV fluid from being delivered to the intended intravenous administration route. In this sense, the subject device augments the type of faults detected by the predicate device (and indeed, any infusion pump) by detecting IV infiltration, consistent with the subject device's classification as an accessory to an infusion pump.

Both the subject and predicate devices monitor deviations in particular characteristics of the IV fluid which are correlative to possible faults in the delivery of the IV fluid to the intended intravenous administration route. The subject device monitors changes in the optical properties of the tissue surrounding the IV insertion site for signs of infusate accumulation in the subcutaneous space (i.e., IV infiltration); the predicate device uses pressure and ultrasonic waves to detect occlusion/blockage and air-in-line, respectively. However, this does not alter the intended use of the (accessory) subject and predicate devices-ensuring the delivery of IV fluids to the intended administration route (the patient's vein).

Both the subject and predicate devices issue visual and audible notifications when the measured values of the monitored characteristics exceed preset threshold values for those monitored characteristics (diffuse reflectance in the case of the subject device, pressure in the case of the predicate device).

5.6.1 Reference Device

To specifically address any safety concerns arising from the use of a red and infrared light source, a reference device was selected (Nellcor OxiMAX N-560 Pulse Oximeter, K021090). The safety of using infrared technology (within specified operating conditions) to determine human tissue properties has been well established by a variety of medical devices, most notably oximeters. The Nellcor OxiMAX N-560 Pulse Oximeter uses near-infrared (NIR) light within similar wavelengths as the ivWatch Model 400 to provide continuous monitoring of oxygenation levels and has been demonstrated as a safe and effective medical device.

5.7 Performance Data

The following performance data were provided in support of substantial equivalence determination and to demonstrate safety and effectiveness.

5.7.1 Biocompatibility

The biocompatibility evaluation of the patient-contacting components of the ivWatch Model 400 device was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing,''' May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA.

The following tests were performed:

  • Sensitization
  • Irritation
  • Cytotoxicity

There are two skin-contacting components of the ivWatch Model 400: the ivWatch sensor receptacle and the ivWatch sensor cable. The ivWatch sensor receptacle complies with the biocompatibility requirements for prolonged duration contact (greater than 24 hours but less than 30 days) on intact skin. The

169 McI aws Circle Williamsburg, VA 23185 1.855.JVWATCH (489.2824) Fax: 757.645.4760 www.ivwatch.com

ivWatch sensor cable complies with the biocompatibility requirements for 24hour contact on intact skin.

5.7.2 Electrical Safety and Electromagnetic Compatibility (EMC)

Electrical safety and EMC testing were conducted on the ivWatch Model 400, consisting of the ivWatch Patient Monitor and sensor cable. The system conforms and meets the requirements of IEC 60601-1-2: 3rd Ed. 2007. ivWatch Model 400 was also tested and determined to be compliant to ANSI/AAMI ES60601-1:2005, 3rd ed. (Medical Electrical Equipment - Part 1: General Requirements for Basic Safety and Essential Performance); IEC 60601-1: 2005 + CORR. 1 (2006) + CORR. 2 (2007).

5.7.3 Software Verification and Validation Testing

Software verification and validation testing for the ivWatch Model 400 were conducted and documented in accordance with the FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." Software validation is compliant to IEC 60601-1 3rd edition - Amendment 1, and therefore IEC 62304.

The software code on the IPM was segregated into two types:

    1. Software whose function is consistent with the "moderate level of concern" classification, as stated in the FDA's "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" (May, 2005). As stated in the quidance document, failures or latent design flaws in software having the "moderate" level of concern may result in minor to moderate injury to the patient, or it may indirectly affect the patient in that incorrect or delayed information could result in injury to the patient.
    1. Software which presents a "minor level of concern."

The device is intended as a supplement (aid) to, and not a replacement for regular clinician assessment of the PIV site (i.e., regular clinician assessment is still in effect). Accordingly, only the modules that involved setting the level and duration of the emitted light were treated as having "moderate" level of concern, since the only software-controlled output that contacts the patient in any way is the light emitted by the LEDs.

5.7.4 Bench Testing

Computer simulations were used to identify the optimal design for the ivWatch sensor. Simulation results were validated in bench tests using an ex vivo porcine foot model. Optical safety testing was performed and indicated that the optical radiation emitted by the ivWatch device is significantly less than the limits set forth by industry standards (ANSI Z136.1 - 2007).

5.7.5 Clinical Studies

A series of six IRB-approved verification and validation clinical studies were performed for the development and validation of the ivWatch Model 400. Verification studies investigated the specific effect of infiltration characteristics or patient attributes on the performance of the ivWatch Model 400 device. The validation studies assessed the performance (e.g., sensitivity, false notification rate) of the ivWatch Model 400 device. The results demonstrated that the ivWatch Model 400 could assist clinicians in identifying the early stages of a PIV infiltration. There were no adverse events during the clinical studies.

5.7.6 Summary

The results of the performance testing indicate that the ivWatch Model 400 is substantially equivalent to the Baxter SIGMA Spectrum Infusion Pump with MDL and raises no concerns about safety or efficacy of the device.

5.8 Conclusions

The ivWatch Model 400 is found to be substantially equivalent to the predicate device, as both have the same intended use and mechanism of action. Any safety concerns arising from the use of a red and infrared light source are addressed using a reference device. Any differences between the ivWatch Model 400 and the predicate were addressed through performance testing and such differences were determined to have no effect on the safety or efficacy of the device.
