Abstract

A stoma creator is provided comprising a flexible tube having a first opening, a tapered dilator portion, having a second opening, the diameter of the first opening being greater than the diameter of the second opening, and a connecting portion. The stoma creator has a tapered dilator having a side wall which gently tapers from approximately 5 French to 14 French. The method for using the device of this invention comprises the step of securing the stomach to the abdominal wall through the use of T-fasteners, inserting a needle percutaneously into the gastric lumen, passing a guidewire through the needle, grasping the guidewire with the endoscope and bringing it out through the mouth, threading the tapered dilator over the guidewire and passing the stoma creator down the throat into the stomach then out through the abdominal wall the stoma creator cutting of the tapered dilator and connecting portion, passing a gastrostomy tube through the flexible tube, with the gastrostomy tube having a balloon adjacent its tip, removing the flexible tube while leaving the guidewire in place, filling the balloon, and withdrawing the guidewire. A similar alternative method is also disclosed.

Claims

1. A stoma creator comprising:

(a) a flexible tube fabricated from a silicone material and having an interior diameter sufficiently large to accommodate a gastrostomy tube;

(b) a tapered dilator fabricated form polyethylene and having a sidewall which gently tapers from a larger size at a first end to a smaller size at a second end; and

a connecting union fabricated from nylon, a first end portion of the connecting union comprising securing means in the form of an undulating sidewall inserted into an end of said flexible tube and secured thereto by an adhesive bond, a second end portion of the connecting union comprising securing means in the form of external ridges inserted into said first end of said tapered dilator and secured thereto by an adhesive bond.

2. A stoma creator according to claim 1 wherein the connecting union has a tapered section intermediate said first end portion and said second end portion.

3. A stoma creator according to claim 1 wherein said flexible tube has an interior diameter sufficiently large to accommodate a 22 French gastostomy tube and the sidewall of the tapered dilator gently tapers from approximately 14 French at said first end to about 5 French at said second end.
