Abstract
In some embodiments a PEG feeding device includes a tube sized to bridge a channel between a stomach and an outer abdominal surface; an internal bolster, and an external bolster. Optionally the bolsters are connected to the tube. The internal bolster may be sized to resist movement out of the stomach through the stoma. The external bolster may be sized to resist movement into the stoma from the outer abdominal surface. The external bolster may include an underside which extends from the tube in a radial direction between the external bolster and the outer abdominal surface. The underside of the outer bolster may contact the outer abdominal surface at a distance from an external opening of the stoma. Optionally the distance between the internal bolster and the external bolster is adjustable. Optionally an angle between one or both of the bolsters and the tube is adjustable.
