Abstract

A balloon is inflated with a flowable material that is semi-solid, or sets and becomes solid after it has entered the balloon. The flowable material is injected into the balloon through the balloon port, enters the balloon, and inflates the balloon. The viscosity of the material, or the solid nature of the material after it sets and solidifies, provides a lower anchor for a device that extends percutaneously into the body, such as a feeding tube.

Claims

1. A method of anchoring a feeding tube, comprising the steps of:

a) inserting a feeding tube into a stomach, wherein said feeding tube comprises an inflatable container, and wherein said inflatable container is positioned inside a gastric wall;

b) inflating said inflatable container after positioning said inflatable container inside the gastric wall by inserting a flowable material into said inflatable container, wherein said flowable material is a material that sets and becomes solid or semi-solid; and

c) allowing said flowable material to set and form an anchor for said feeding tube after said flowable material is inserted into said inflatable container.

2. A method of anchoring a feeding tube as described in claim 1, wherein said feeding tube comprises a bolster that is positioned above said inflatable container, and wherein, after insertion of said feeding tube into said stomach, a gastric wall is between said bolster and said inflatable container.

3. A method of anchoring a feeding tube as described in claim 1, wherein said feeding tube comprises a port that is suitable for receiving a device for inserting said flowable material, and a feed port.

4. A method of anchoring a feeding tube as described in claim 3, wherein said port that is suitable for receiving a device for inserting said flowable material comprises a one way valve.

5. A method of anchoring a feeding tube as described in claim 1, wherein said flowable material is a polymer, and wherein said polymer sets to form a solid or a semisolid after said flowable material is inserted in said inflatable container.

6. A method of anchoring a feeding tube as described in claim 1, wherein said flowable material is a polymer.

7. A method of anchoring a feeding tube as described in claim 1, wherein said flowable material comprises a first part and a second part, and wherein said first part and said second part combine and set to form as a solid or a semisolid after said flowable material is inserted in said inflatable container.

8. A method of anchoring a feeding tube as described in claim 1, wherein said flowable material comprises an antimicrobial agent.

9. A method of anchoring a feeding tube as described in claim 1, wherein said flowable material sets to form a solid.
