Device for intubation of percutaneous endoscopic ostomy
First Claim
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.

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.

7. In a method for intubating an ostomy formed by a percutaneous endoscopic technique, the technique including inserting a fiberoptic endoscope into a patient'"'"'s mouth, advancing the endoscope into the patient to illuminate and externally visualize a desired endoscope positioning, forming the ostomy through abdominal and gastric walls of the patient at the desired endoscope positioning, and passing one end of a suture externally through the ostomy and drawing the one end of the suture up through and out of the patient'"'"'s mouth, an other end of the suture remaining outside the gastrostomy, the improvement comprising the steps of:
-
tying the suture to one end of a tube having at least an inflation lumen and a fluid lumen, the tube having a port near the one end to dispose the inflation lumen to ambient air and an outlet at an other end to convey fluid from the fluid lumen into the patient, an enclosed elongated sleeve joined to the one end of the tube, the sleeve having means for selectively sealing the port to permit escape of air from the inflation lumen but preventing ingress of air into the inflation lumen; deflating an inflatable retention member joined near the other end of the tube, the member being inflatable through the inflation lumen, the means for sealing the port preventing re-inflation of the member; intubating the tube by pulling on the other end of the suture to draw and lead the one end of the tube in a retrograde manner through the patient until the retention member abuts against inner tissue surfaces of the ostomy; and
,inflating the retention member to anchor the member against the inner tissue surfaces of the ostomy. - View Dependent Claims (8, 9, 10, 11, 13, 14, 15, 16)
