Functionality and Accuracy of the smART System in Real-Life ICU Settings

January 17, 2023 updated by: ART Medical Ltd.

Total participants in the "Functionality and Accuracy of the smART System in Real-Life ICU Settings" are 10 participants - in the current Jefferson study site there were 8 participants and in the Sheba study site (identifier NCT03689985) there were 2 participants.

This study is conducted in order to validate the functionality and accuracy of the smART™ System in a real-life ICU setting. The smART™ Feeding Tube System is a novel system with nasogastric tube developed by ART Medical (Healthcare) Ltd, based on sensor-lined tubes that transmit real-time information to an external console. The smART™ feeding tube is equipped with reflux sensors which alert when gastric contents regurgitating into the esophagus. In addition, the smART™ feeding tube is equipped with sensors designed to provide information about the location of the tube thus assisting in reducing the incident of misplacement during first positioning. The smART™ feeding tube is also automatically and in real-time stops feeding if the feeding tube moves out of position during ongoing use or detect gastric content in esophagus. Furthermore, smART™ Feeding Tube System can guide operator to correctly re-position the tube. Lastly the smART™ Feeding Tube System is equipped with an anti-reflux mechanism and automatic Gastric Residual Volume (GRV).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants for Whom the System is Able to Accurately Guide and Ensure Correct Initial Feeding Tube Placement , Verified by X-ray
Time Frame: Enrollment visit
Enrollment visit
Number of Tube "Out of Position" Alerts During Ongoing Use
Time Frame: Enrollment day up to 7 days
Any patient , in which the system alerted of tube out of position , the staff verified this according to the tube markings and if mispositioning occurred, this was documented the event in the CRF "out of position"
Enrollment day up to 7 days
Number of Automatic System Generated Feeding Stops in Response to Tube Displacement.
Time Frame: From insertion of feeding tube up to its removal , an average of 7 days.
In order to prevent aspiration, the system software automatically pinches the feeding tube. Verification of the functionality of automatic feeding cessation when tube displacement is detected was done as part of the formal verification of the system
From insertion of feeding tube up to its removal , an average of 7 days.
Number of Major Reflux Event That Lead to Automatically Stops Feeding
Time Frame: From insertion of feeding tube up to its removal , an average of 7 days.

Overfeeding is the intolerance of the stomach to feeding material that causes reflux. There are two types of reflux events as defined by the system; minor-reflux and massive-reflux. Both types of reflux events are detected by the level of fluids interacting with the sensors, the severity is defined by gastric content reaching above the lower esophageal sphincter (LES):

  1. Minor reflux is defined as gastric content that did not pass the balloon located in the center of the esophagus.
  2. Massive reflux is defined as gastric content that reaches immediately above the balloon.
From insertion of feeding tube up to its removal , an average of 7 days.
Average Duration of Balloon Inflation in Response to a Reflux Episode.
Time Frame: From insertion of feeding tube up to its removal , an average of 7 days.
Massive reflux of gastric content can aspirate into the lungs and cause pneumonia. The system detects the reflux event and will (according to an algorithm) stop the feeding and or inflate a balloon and evacuate gastric residuals from the stomach to lower the risk of aspiration.
From insertion of feeding tube up to its removal , an average of 7 days.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Recording of Impedance Detected by the System and Correlation to Patient Positioning.
Time Frame: From insertion of feeding tube up to its removal , an average of 7 days.
Positions changes were correlated to reflux events captured by the system console. Any position change of the patient was captured by the video camera located above the patient's bed.
From insertion of feeding tube up to its removal , an average of 7 days.
Number of Participant With Change in Ventilator Associated Pneumonia (VAP) and/or Acute Respiratory Distress Syndrome (ARDS) as a Measure of Effectiveness in Reducing Aspiration of Gastric Contents
Time Frame: 56 - 168 hours per patient
The first and the last X-ray images obtained for patients during the study were used to evaluate Ventilator Associated Pneumonia (VAP) and/or Acute respiratory distress syndrome (ARDS)
56 - 168 hours per patient
