A stoma dilation device that includes a tubular support and an inflatable dilation portion located on the tubular support. The inflatable dilation portion includes a stiffening portion and inflation lumen. The device may have a retention portion configured to have a diameter upon full, unrestrained inflation that is greater than the diameter of the dilation portion. The device is designed to be placed in a patient to dilate the stoma for the installation of a catheter feeding tube. The device may be placed and withdrawn with the use of an endoscope which need be inserted into the patient only one time. The single insertion of the endoscope significantly reduces the trauma to the patient in comparison with multiple endoscope insertion methods. |
