LOW PROFILE GASTROSTOMY DEVICE WITH DOME

摘要

A gastrostomy device (30) for easier insertion into an established stoma is provided with an apertured dome (34) connected at its bottom wall to a tubular shaft (31), wherein the dome is particularly characterized by having the sidewall (38) thinned from apex to bottom wall whereby the dome, when elongated with an obturator, stretches smoothly and readily to very close to the diameter of the tubular shaft. The device is ordinarily provided with a one-way valve (42) mounted in the dome as well as with a retention flange (32) at the outer end of the tubular shaft. Preferably the one-way valve is a cross-slit duckbill valve of novel design.
