Description

A low-profile, balloon-retained gastrostomy “button” designed for long-term enteral access in pediatric and adult patients. This MIC-KEY by Avanos Medical configuration supports enteral feeding, medication delivery, and gastric decompression while remaining skin level to help minimize snagging and interference with clothing. The internal inflatable retention balloon secures the device, and the ENFit feeding port incorporates an anti-reflux valve that remains closed when no extension set is attached. Keep the port capped when not in use.
