1. A device for intubating an ostomy, such as a gastrostomy, formed by a percutaneous endoscopic technique, comprising:

  • a tube having at least a fluid lumen and an inflation lumen, the tube having a port near one end to dispose the inflation lumen to ambient air and an outlet at an other end to convey fluid from within the fluid lumen into the patient;

    a retention member joined near the other end of the tube, the member being inflatable through the inflation lumen, the member in a deflated state having a generally edge-free outer configuration to facilitate intubation, the member in an inflated state defining at least one edged and generally flat retention and anchoring surface;

    an elongated sleeve joined to and enclosing the one end of the tube, the sleeve being edge-free to define an edge-free outer configuration for gently parting gastroenteral tissues during intubation;

    means for sealing selectively the ambient air port of the tube, the sealing means permitting escape of air from the inflation lumen through the port but preventing ingress of air into the inflation lumen;

    wherein prior to intubation of the device into a patient the retention member is compressed to deflate the member by expelling air out of the inflation lumen through the port, the sealing means seals the port to prevent re-inflation of the member, the one end of the tube is drawn through the patient in a retrograde manner until the deflated retention member abuts against inner tissue surfaces of the gastrostomy, air is introduced into the inflation lumen to re-inflate the member and anchor the device against the inner tissue surfaces of the gastrostomy, and the inflation lumen is sealed to prevent deflation of the retention member.
