ABSTRACT:
A device for intubating an ostomy, formed by a percutaneous endoscopic technique including a multi-lumen tube, having at least a fluid delivery lumen and an inflation lumen. The tube includes 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 a patient. An inflatable member, is joined near the other end of the tube and is inflatable and deflatable through the inflation lumen. In a deflated state, the member assumes an edge-free outer configuration to facilitate intubation of the device into the patient. In a fully inflated state, the member assumes an outer configuration defining an edged, generally flat surface to more diffusely contact and abut against inner tissue surfaces surrounding the gastrostomy. Joined to the one end of the tube is an elongated tapered sleeve which encloses the one end of the tube. The tapered end of the sleeve carries a suture loop for use in intubating the device. The tube seals the ambient air port through use of a pressure responsive skirt portion disposed from the sleeve or through use of a frangible plug. Deflation of the member is accomplished by a unique deflation collar having a tapered passage. The inflatable member is drawn through the tapered passage.
