Masimo Announces FDA 510(k) Clearance of Radius Tº™ for Prescription and Over-the-Counter (OTC) Use

Rhea-AI Summary

Masimo (NASDAQ: MASI) has received FDA 510(k) clearance for its Radius Tº™, a wearable thermometer for continuous, noninvasive body temperature monitoring. Suitable for patients aged five and older, it features Bluetooth connectivity for easy integration with Masimo's monitoring solutions and smartphone applications. The device supports hospital automation and streamlines workflows with its single-patient use design. Radius Tº offers enhanced accuracy compared to traditional thermometers, providing critical temperature data for both clinicians and consumers. This clearance marks a significant expansion in Masimo's temperature monitoring capabilities.

Positive

• FDA 510(k) clearance for Radius Tº, expanding market access.
• Continuous and noninvasive monitoring enhances patient care.
• Bluetooth connectivity improves integration with existing health systems.
• Single-patient use design reduces cross-contamination risk.

Negative

• Potential challenges in market adoption against traditional thermometers.

Masimo (NASDAQ: MASI) announced today that Radius Tº™, a wearable, wireless thermometer that measures body temperature continuously and noninvasively, has received FDA 510(k) clearance for both prescription and over-the-counter (OTC) use on patients and consumers five years and older. Featuring continuously trending temperature measurements and Bluetooth^® connectivity, Radius Tº automates remote, continuous body temperature status for clinicians through its paired connection to a Masimo patient monitoring or telehealth solution, and for consumers through the Masimo Radius Tº smartphone application. Radius Tº is part of the growing family of tetherless Masimo technologies that includes Radius PPG™, which offers Masimo SET^® Measure-through Motion and Low Perfusion pulse oximetry, and Radius PCG™, which provides mainstream capnography.

For prescription use, Radius Tº is compatible with both the Root^® Patient Monitoring and Connectivity Hub and the Rad-97^® patient monitor for use in the hospital, as part of the Masimo Hospital Automation™ platform. Radius Tº can also be paired to a patient’s smartphone using the Masimo SafetyNet™ app, for remote patient management from the home or other care location. The wireless thermometer is designed to help streamline workflows, with its convenient wearability, continuous measurements, and wireless connectivity, reducing the need for intermittent manual temperature checks with traditional probes that require a clinician’s presence at the bedside. Each Radius Tº wireless thermometer is single-patient use, to reduce the risk of cross-contamination between patients, with an 8-day battery life and shower-proof adhesive, reducing the need to remove or replace the sensor—thus supporting a hospital’s or caregiver’s temperature monitoring and infection control workflow.

Using a proprietary algorithm, Radius Tº provides continuous body temperature measurements that are approximations of sublingual temperatures captured from an oral probe. Radius Tº supports continuous body temperature performance that goes beyond simple skin surface temperature measurements, and remains reliable even when environmental temperatures are fluctuating. Radius Tº provides trended data to help clinicians manage and review a patient’s high fever risks and fever progress over time.

Radius Tº is easily integrated into the Masimo Hospital Automation platform, through Root or Rad-97, allowing automatic transfer of continuous body temperature data to a hospital’s electronic medical records (EMRs) or surveillance monitoring solution, thus streamlining clinicians’ ability to gain a more insightful picture of each patient’s physiological status, regardless of the clinician’s physical location.

For consumers, Radius Tº represents a paradigm shift in thermometry by making it continuous, wearable, and hassle-free. Traditional periodic and invasive methods depend on the user repeatedly conducting a series of steps that can interrupt daily activities, including sleep, and can miss body temperature trends and patterns. With a traditional thermometer, a person may only notice a spike in temperature hours after a spike has occurred, or may not even become aware of it if it is during sleep. By contrast, Radius Tº continuously measures temperatures and seamlessly transmits data and customizable temperature notifications to the Masimo Radius Tº app on the user’s smartphone – helping caregivers, such as parents, monitor loved ones’ temperatures even while they sleep and providing continuous insight into changes and trends in their temperature. In addition, Radius Tº is applied comfortably on the upper chest, avoiding the potential discomfort of other wearable devices that rely on placement in the armpit.

Joe Kiani, Founder and CEO of Masimo, said, “Radius Tº was first made available in the U.S. under an FDA COVID-19 enforcement policy for thermometers as part of Masimo SafetyNet – where it quickly demonstrated its value in improving clinician workflows through its continuous, remotely accessible body temperature measurements for patients recovering or quarantined at home. Now, with the FDA 510(k) clearance, the availability of the Radius Tº is being expanded for use by both clinicians and consumers to help monitor and track body temperatures in all thermometer applications.”

About Masimo

Masimo (NASDAQ: MASI) is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. Our mission is to improve patient outcomes, reduce the cost of care, and take noninvasive monitoring to new sites and applications. Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.¹ Masimo SET^® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,² improve CCHD screening in newborns,³ and, when used for continuous monitoring with Masimo Patient SafetyNet™ in post-surgical wards, reduce rapid response team activations, ICU transfers, and costs.^4-7 Masimo SET^® is estimated to be used on more than 200 million patients in leading hospitals and other healthcare settings around the world,⁸ and is the primary pulse oximetry at 9 of the top 10 hospitals according to the 2020-21 U.S. News and World Report Best Hospitals Honor Roll.⁹ Masimo continues to refine SET^® and in 2018, announced that SpO₂ accuracy on RD SET^® sensors during conditions of motion has been significantly improved, providing clinicians with even greater confidence that the SpO₂ values they rely on accurately reflect a patient’s physiological status. In 2005, Masimo introduced rainbow^® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb^®), oxygen content (SpOC™), carboxyhemoglobin (SpCO^®), methemoglobin (SpMet^®), Pleth Variability Index (PVi^®), RPVi™ (rainbow^® PVi), and Oxygen Reserve Index (ORi™). In 2013, Masimo introduced the Root^® Patient Monitoring and Connectivity Platform, built from the ground up to be as flexible and expandable as possible to facilitate the addition of other Masimo and third-party monitoring technologies; key Masimo additions include Next Generation SedLine^® Brain Function Monitoring, O3^® Regional Oximetry, and ISA™ Capnography with NomoLine^® sampling lines. Masimo’s family of continuous and spot-check monitoring Pulse CO-Oximeters^® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7^® and Radius PPG™, portable devices like Rad-67^®, fingertip pulse oximeters like MightySat^® Rx, and devices available for use both in the hospital and at home, such as Rad-97^®. Masimo hospital automation and connectivity solutions are centered around the Masimo Hospital Automation™ platform, and include Iris^® Gateway, iSirona™, Patient SafetyNet, Replica™, Halo ION™, UniView^®, UniView :60™, and Masimo SafetyNet™.
