Device for intubation of percutaneous endoscopic ostomy
| Details |
Inventors: Quinn, David G.; Edwards, II, Robert B.; Andersen, Erik;
Assignee: Corpak, Inc. (Wheeling, IL)
Primary Examiner: Grieb; William H.
Assistant Examiner:
Attorney, Agent or Firm: Wallenstein Wagner Hattis & Strampel, Ltd.
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. |

DETAILED DESCRIPTION While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention.
The present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiment illustrated.
Referring now to the drawings, FIG.
1 discloses a preferred embodiment of device 10 of the present invention comprised of a multi-lumen enteral feeding tube.
As disclosed in FIG.
2 and best disclosed in FIG.
2A, feeding tube 12 includes at least an inflation lumen 14 and a fluid delivery lumen 16.
Lumens 14 and 16 are separated by a septum 18.
As disclosed in FIG.
2, one end 12A of tube 12 has at least one ambient air port 20 which as will be disclosed later in greater detail, disposes inflation lumen 14 in communication with ambient air.
At an other end 12B of tube 12, the fluid outlet 22 (shown in phantom in FIG.
2) conveys fluid from fluid lumen 16 into a patient.
Sealably secured to end 12A of tube 12 is an enclosed sleeve 24, preferably having a tapered elongated conical terminal end 26.
The tapered conical outer configuration of terminal end 26 permits atraumatic parting of esophageal and gastric tissues during the intubation process.
As disclosed in FIGS.
1 and 2 disposed on the terminal end 26 of sleeve 24 is a suture loop 28 which permits device 10 to be tied to the end of the suture extending from the patient's mouth during the percutaneous endoscopic technique (not shown in the drawings).
As disclosed in FIG.
2, suture loop 28 may preferably fully extend through sleeve 24 through a channel 32 and be secured to end 12A of tube 12 by a fastening knot or other fastening device 34 secured to the septum 18.
Joined to sleeve 24 is a skirt portion 36 which circumferentially surrounds end 12A of tube 12 in such a manner to create an airtight seal between skirt portion 36 and outer surfaces of end 12A
