INVOS 7100 Cerebral/Somatic Oximetry System Receives 510(k) Clearance for Pediatric Indications

“Timing is critical for vulnerable pediatric patients, and the INVOS™ 7100 system can alert clinicians to changes in patient condition before traditional monitored parameters even react,”1, 2 said Frank Chan, president of the Patient Monitoring business, which is part of the Medical Surgical Portfolio at Medtronic. “The INVOS™ 7100 system can help clinicians decide if intervention is necessary — a core component in successful outcomes. And our technology consistently enables users to determine if they need to intervene sooner.”1-6

The INVOS™ near-infrared spectroscopy monitoring system has been previously cleared for use in adult patients and is the clinical reference standard for regional oximetry.7 The real-time measures of tissue perfusion and oxygenation provided by the INVOS™ 7100 system provide early alerts to changes in perfusion before other vital sign measurements.1, 2   This data may indicate to clinicians that a patient is becoming critical — providing them the crucial time needed to treat newborns and young patients.

“There are so many time-critical conditions clinicians face when treating some of our youngest patients in intensive care units, from RSV to complex heart conditions and beyond. We see this as an opportunity to equip providers with technology that can help improve outcomes among the most vulnerable populations,” said Sam Ajizian, MD, FAAP, FCCM, CPPS, and chief medical officer of the Patient Monitoring business at Medtronic. “We are thrilled that the INVOS™ 7100 system has been cleared for pediatric indications.”

The technology inside the INVOS™ 7100 system delivers first-alert performance with its unique algorithms that measure acute alterations in hemodynamics, regional oxygen saturation, and oxygen metabolism.1, 2  The system provides continuous, noninvasive readings of organ-specific regional blood oxygen levels in up to four site specific areas chosen by the care team and oxygen saturation from vascular beds to assess organs individually, or in combination to track brain/body perfusion shifts.

The INVOS™ 7100 system with the pediatric indications will be available worldwide for commercial use in spring 2022.

The INVOS™ monitoring system should not be used as the sole basis for diagnosis or therapy and is intended only as an adjunct in patient assessment.
