The smARTrack™ Feeding Tube System is designed to aid qualified operators in the placement of the smARTrack Feeding Tube into the stomach of patients requiring enteral feeding. The smARTrack™ tube is equipped with sensors designed to provide information about the location of the tube tip relative to the lower esophageal sphincter (LES) thus assisting in reducing the incidence of misplacement during first positioning. The smARTrack™ tube also monitors the position continuously during the course of the feeding and automatically and in real time alerts of tube migration. The smARTrack console is equipped with a motorized mechanism which automatically and in real-time stops feeding if the feeding tube moves out of position during ongoing use. Furthermore, smARTrack™ Feeding Tube System can guide operator to correctly re-position the tube.
The smARTrack™ Feeding Tube is intended for gastric decompression, gastric lavage, and the administration of nutrition, fluids and medications by the naso-enteric route for patients who have an intact gastrointestinal tract but are physically unable to manage nutritional intake through normal mastication and deglutition.
Indications for use as stated in the FDA summary.
