Abstract
Abstract A gastrostomy feeding port includes a deformable, conical tip portion having at least one side aperture therethrough, a tube portion which extends rearwardly from the tip portion, a fitting portion on the rear end of the tube portion, a removable valve portion in the fitting portion and a flange portion which extends outwardly from the fitting portion. The feeding port is adapted to be installed in a patient so that the tube portion extends through a preestablished stoma in the patient's stomach with the tip portion located in the patient's stomach and the fitting portion and the flange portion engaging the skin of the patient adjacent the stoma. Since the valve portion is removable received in the fitting portion, it can be repaired or replaced if needed without replacing the entire feeding port.
