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 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.

Claims

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 generally flat retention and anchoring surface;

a tapered sleeve joined to and sealing the one end of the tube, the sleeve having an edge-free outer configuration for gently parting gastroenteral tissues during intubation;

means for sealing the ambient air port of the tube;

wherein prior to intubation, the retention member is compressed to deflate the member by expelling air out of the inflation lumen through the port, the sealing means is used to seal 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 ostomy, air is introduced into the inflation lumen to re-inflate the member and anchor the device against the inner tissue surfaces of the ostomy, and the sealing means re-seals the inflation lumen to prevent deflation of the retention member.

2. The device of claim 1 wherein the means for sealing the ambient air port includes:

a skirt portion joined to the sleeve, the skirt portion forming an airtight seal about the circumference of the tube and covering the ambient air port, the skirt portion expanding outwardly in response to greater air pressure within the inflation lumen to permit expulsion of air out of the port and contracting inwardly in response to greater air pressures outside the inflation lumen to seal the port.

3. The device of claim 1 wherein the inflatable retention member includes a substantially foam filled annular cuff.

4. The device of claim 3 wherein the annular cuff has at least one generally flattened surface for abutment against the inner surfaces of the gastrostomy.

5. The device of claim 1 wherein a loop of suture is carried on a terminal end of the sleeve to draw the device in a retrograde manner through the esophagus and the ostomy.

6. The device of claim 5 wherein the terminal end of the sleeve has a conical shape.

7. The device of claim 1 wherein the means for ambient air port sealing the includes:

a plug member having a stem being dimensioned to fit within and occlude the inflation lumen;

an enlarged gripping member on one end of the stem; and

,

a frangible region on the stem proximate to the gripping member.

8. The device of claim 1 further including means for deflating the retention member.

9. The device of claim 8 wherein said means for deflating the retention member includes:

an elongated, generally flat strap, one end of the strap having barb members on outer surfaces thereof; and

, the other end of the strap having means for receiving the barb members.

10. In a method for intubating an ostomy formed by a percutaneous endoscopic technique, the technique including inserting an 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 elongated tapered sleeve joined to and sealing the one end of the tube;

deflating an inflatable retention member joined near the other end of the tube, the member being inflatable through the inflation lumen;

sealing the inflation lumen to prevent 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

,

re-inflating the retention member to anchor the member against the inner tissue surfaces of the ostomy.

11. The method of claim 10 wherein the step of deflating the retention member includes:

compressing a foam-filled inflatable retention cuff until air is expelled out of the cuff and the inflation lumen.

12. The method of claim 10 wherein the step of inflating the retention member includes:

introducing ambient air into the inflation lumen.

13. The method of claim 10 wherein the step of introducing air into the inflation lumen includes:

severing the tube below the tapered sleeve to expose the inflation lumen to ambient air.

14. The method of claim 10 wherein after the step of severing the tube, further including the step of:

joining a tube connector device to the severed end of the tube.

15. The method of claim 10 wherein the step of tying the suture to the one end of the tube includes:

tying the suture to a suture loop carried from a terminal end of the enclosed sleeve.

16. The method of claim 10 wherein the ostomy includes a gastrostomy.

17. The method of claim 10 wherein the ostomy includes a cystostomy.
