Description
Overview
The Avanos MIC-KEY Low-Profile Balloon Gastrostomy Button is a skin-level G-tube designed for long-term enteral nutrition and medication delivery in pediatric through adult patients. Its low-profile form factor helps reduce interference with clothing and activity. The device also supports gastric venting and decompression and can be used in home care and clinical settings.
