Abstract

A unique 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. A retention member, preferably an inflatable cuff, is joined near the other end of the tube and is inflatable and deflatable through the inflation lumen. In a deflated state, the cuff assumes an edge-free outer configuration to facilitate intubation of the device into the patient. In a fully inflated state, the cuff 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 sleeve includes a skirt portion which creates a circumferential air-tight seal about the tube to selectively seal the ambient air port. The skirt portion is air pressure responsive to permit escape of air from the inflation lumen through the port but preventing the ingress of air into the inflation lumen through the port.
