ABSTRACT:
A gastrostomy device includes a tubular portion and an internal bolster having a radial wing secured to the tubular portion. The internal bolster is flexible and permits elastic deformation between a first orientation with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfurled. A constraining member encases the internal bolster to retain the internal bolster in the first orientation and to cover at least a major portion of the wrapped wing. Removal of the casing permits the internal bolster to move from the first orientation to the second orientation. The internal bolster may be deployed by a ripcord, freeing the internal bolster into the patient' stomach and deploying the internal bolster to the second orientation. Alternatively, the internal bolster may be deployed by the constraining member being dissolved by the patient's bodily fluids located inside the patient's stomach.
