Abstract

A stoma dilation device that includes a tubular support defining a continuous pathway through the device; at least one inflatable dilation balloon and at least one inflatable retention balloon located on the tubular support; and inflation lumens for each balloon. The inflatable dilation balloon forms at least a first portion of the device and the inflatable retention balloon forms at least a second portion of the device. The inflatable retention balloon is configured to have a diameter upon full, unrestrained inflation that is greater than the largest diameter of the inflatable dilation balloon upon inflation.

First claim

We claim:

1. A system for dilating a stoma to a gastric lumen and inserting a feeding tube, the system comprising:
a stoma dilation device comprising:
a tubular support having a length, width and a longitudinal axis, the tubular support defining a continuous pathway through the device;
an inflatable dilation balloon located on the tubular support toward a distal end of the device, the dilation balloon being oriented axially on the tubular support for positioning the dilation balloon, within a needle tract to a gastric lumen, the inflatable dilation balloon configured to expand the needle tract into a stoma tract, the inflatable dilation balloon having an inflated cross-section ranging from 3 to 10 millimeters;
a dilation balloon inflation lumen;
an inflatable retention balloon located on the tubular support adjacent the dilation balloon, the retention balloon located at a proximal section of the device, the proximal section of the device positioned within the gastric lumen, the retention balloon having a diameter upon full, unrestrained inflation that is greater than the diameter of the dilation balloon upon inflation in order to stabilize a wall of the gastric lumen; and
a retention balloon inflation lumen,
the inflatable dilation balloon having two open ends attached to the tubular support and the inflatable retention balloon having two open ends attached to the tubular support,
wherein one open end of the two open ends of the inflatable dilation balloon is adjacent one open end of the two open ends of the inflatable retention balloon and at least one of the adjacent open ends is inverted to position dilation balloon and the retention balloon close together; and

a feeding tube configured to fit over the fully or partially inflated dilation balloon through the expanded needle tract and into the portion of the gastric lumen stabilized by the retention balloon, the feeding tube extending from skin at an exterior of a patient, through the needle tract, and into the gastric lumen to provide feeding solutions directly to the gastric lumen, wherein the stoma dilation device is configured to be deflated and at least a portion of the device withdrawn through the feeding tube.

2. The stoma dilation device of claim 1 , wherein the inflatable retention balloon is configured to have a diameter upon full, unrestrained inflation that is 1.5 times to 3 times greater than the diameter of the inflatable dilation balloon upon inflation.

3. The stoma dilation device of claim 1 , wherein the open end of the inflatable dilation balloon adjacent the open end of the inflatable retention balloon is inverted.

4. The stoma dilation device of claim 3 , wherein the open end of the inflatable retention balloon adjacent the open end of the inflatable dilation balloon is inverted such that the adjacent open ends are both inverted.

5. The stoma dilation device of claim 1 , wherein the open end of the inflatable retention balloon adjacent the open end of the inflatable dilation balloon is inverted.

6. The stoma dilation device of claim 5 , wherein the open end of the inflatable dilation balloon adjacent the open end of the inflatable retention balloon is inverted such that the adjacent open ends are both inverted.

7. The stoma dilation device of claim 1 , wherein inflatable dilation balloon and the inflatable retention balloon are each made of a different material.

8. The stoma dilation device of claim 1 , further comprising an inflation lumen having a plug is positioned within the inflation lumen to define the dilation balloon inflation lumen and the retention balloon inflation lumen, the dilation balloon inflation lumen extending from the plug to a distal end of the device and the retention balloon inflation lumen extending from the plug to a proximal end of the device.

9. A stoma dilation device for expanding a needle tract to a gastric lumen into a stoma tract, the stoma dilation device comprising:
a tubular support having a length, width and a longitudinal axis, the tubular support defining a continuous pathway through the device;
at least two different inflatable balloons in series, at least a first balloon oriented axially on the tubular support and having two open ends attached to the tubular support forming a dilation region of the device for expanding a needle tract to a gastric lumen into a stoma tract, the first balloon having an inflated diameter ranging from 3 to 10 millimeters, and at least a second balloon having two open ends attached to the tubular support forming a retention region defining a second portion of the device;
a balloon inflation lumen,
wherein a plug is positioned between the first balloon and the second balloon within the balloon inflation lumen, the plug dividing the balloon inflation lumen to define a first balloon inflation lumen and a second balloon inflation lumen, the first balloon inflation lumen extending from the plug to a distal end of the device and the second balloon inflation lumen extending from the plug to a proximal end of the device, and
wherein the retention region is configured to have a diameter upon full, unrestrained inflation that is 1.5 times to 3 times greater than the diameter of the dilation region upon inflation.

10. The stoma dilation device of claim 9 , wherein at least one open end of the second balloon is inverted.

11. The stoma dilation device of claim 10 , wherein the second balloon is oriented axially on the tubular support.

12. The stoma dilation device of claim 10 , wherein one open end of the first balloon is adjacent one open end of the second balloon, and wherein the adjacent open ends are both inverted to provide a close fit between the first balloon and the second balloon.

13. A system for dilating a stoma to a gastric lumen and inserting a feeding tube, the system comprising:
a stoma dilation device comprising:
a tubular support having a length, width and a longitudinal axis, the tubular support defining a continuous pathway through the device;
an inflatable dilation balloon located on the tubular support for dilating a stoma tract;
a dilation balloon inflation lumen;
an inflatable retention balloon located on the tubular support adjacent the dilation balloon, the retention balloon for stabilizing a portion of a gastric lumen in communication with the stoma tract; and
a retention balloon inflation lumen; and

a feeding tube configured to fit over the fully or partially inflated dilation balloon through the dilated stoma tract and into the portion of the gastric lumen stabilized by the retention balloon, the feeding tube extending from skin at an exterior of a patient, through the stoma tract, and into the gastric lumen to provide feeding solutions directly to the gastric lumen,
wherein the stoma dilation device is configured to be deflated and at least a portion of the device withdrawn through the feeding tube.

14. The system of claim 13 , wherein the retention balloon is oriented axially on the tubular support.

15. A system for dilating a stoma to a gastric lumen and inserting a feeding tube into the stoma, the system comprising:
a stoma dilation device comprising:
a tubular support having a length, width and a longitudinal axis, the tubular support defining a continuous pathway through the device;
an inflatable dilation balloon located on the tubular support for dilating a stoma tract, the inflatable dilation balloon having an inflated diameter ranging from 3 to 10 millimeters;
a dilation balloon inflation lumen;
an inflatable retention balloon located on the tubular support adjacent the dilation balloon, the retention balloon being configured for s
