Abstract: The present invention is directed to a gastrostomy device comprising, a tubular portion defining a longitudinal axis, an internal bolster having a radial wing secured to the tubular portion, the internal bolster being flexible to permit elastic deformation between a first orientation generally aligned with the longitudinal axis, with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfurled and extending generally transverse to the tubular portion longitudinal axis and a constraining member encasing the internal bolster to retain the internal bolster in the first orientation, with the wing wrapped into the generally cylindrical configuration, and to cover at least a major portion of the wrapped wing, wherein the removal of the casing permits the internal bolster to move from the first orientation to the second orientation.
