Abstract

A feeding tube device for delivering a substance into a stomach of a patient is disclosed, comprising a feeding tube, an overlapping segment integrally formed with and extending from the distal end of the feeding tube, and an inflation lumen defined within the feeding tube. The overlapping segment may be configured to surround at least a portion of the distal end of the feeding tube to form a balloon structure in communication with the inflation lumen. The overlapping segment may also be sealed against at least a portion of the distal end of the feeding tube device. A second overlapping segment may also be integrally formed with and extend from the proximate end of the feeding tube, with the second overlapping segment configured to surround at least a portion of the proximate end of the feeding tube to form a second balloon structure. A corresponding method of manufacturing is also disclosed.

Claims

1. A feeding tube device for delivering a substance into a stomach of a patient, comprising:

a feeding tube comprising a proximate end and a distal end;

a first overlapping segment integrally formed with and extending from the distal end of the feeding tube, the first overlapping segment surrounding a distal region of the feeding tube to form a first balloon structure in fluid communication with a first inflation lumen; and

a second overlapping segment integrally formed with and extending from the proximate end of the feeding tube, the second overlapping segment surrounding a proximate region of the feeding tube to form a second balloon structure in fluid communication with a second inflation lumen.

2. The feeding tube device of claim 1, wherein the distal end of the feeding tube further comprises a receiving surface, and the first overlapping segment comprises a sealing surface configured to seal against at least a portion of the receiving surface.

3. The feeding tube device of claim 2, wherein the sealing surface comprises at least one coupling structure and the receiving surface comprises at least one coupling recess configured to receive the at least one coupling structure.

4. The feeding tube device of claim 2, wherein at least a portion of the sealing surface is affixed to at least a portion of the receiving surface.

5. The feeding tube device of claim 2, wherein at least a portion of the sealing surface is compressed against at least a portion of the receiving surface.

6. The feeding tube device of claim 1, wherein the first overlapping segment comprises a plurality of circumferential rib structures.

7. The feeding tube device of claim 1, wherein the distal end of the feeding tube is substantially frustoconical in shape.

8. The feeding tube device of claim 1, wherein the first balloon structure extends beyond the distal end of the feeding tube device when the first balloon structure is inflated.

9. The feeding tube device of claim 1, wherein the first overlapping segment is formed of a substantially non-pliant material.

10. The feeding tube device of claim 9, wherein the substantially non-pliant material is polyethylene terephthalate.

11. The feeding tube device of claim 1, wherein the feeding tube and the first overlapping segment integrally formed with and extending from the distal end of the feeding tube are both formed of the same material or combination of materials.

12. A method of manufacturing a feeding tube device, comprising:

providing a feeding tube comprising a proximate end, a distal end, an exterior surface, and an interior surface;

integrally forming a first overlapping segment with and extending from the distal end of the feeding tube, the first overlapping segment comprising an exterior surface and an interior surface;

defining a first inflation lumen within at least a portion of the feeding tube;

disposing the first overlapping segment around at least a portion of the distal end of the feeding tube;

sealing at least a portion of the exterior surface of the first overlapping segment to the exterior surface of the distal end of the feeding tube to form a first balloon structure in fluid communication with the first inflation lumen;

integrally forming a second overlapping segment with and extending from the proximate end of the feeding tube, the second overlapping segment comprising an exterior surface and an interior surface;

defining a second inflation lumen within at least a portion of the feeding tube; and

sealing at least a portion of the exterior surface of the second overlapping segment to the exterior surface of the proximate end of the feeding tube to form a second balloon structure in fluid communication with the second inflation lumen.

13. The method of claim 12, further comprising affixing at least a portion of the exterior surface of the first overlapping segment to the exterior surface of the distal end of the feeding tube.

14. The method of claim 12, further comprising compressing at least a portion of the first overlapping segment against at least a portion of the distal end of the feeding tube.

15. A gastric feeding tube device, comprising:

a feeding tube comprising a proximate end, a distal end, an exterior surface, and an interior surface;

a first overlapping segment integrally formed with and extending from the distal end of the feeding tube, the first overlapping segment comprising an exterior surface and an interior surface;

a first inflation lumen defined within at least a portion of the feeding tube;

wherein the first overlapping segment is configured to at least partially surround at least a portion of the distal end of the feeding tube, with at least a portion of the exterior surface of the first overlapping segment sealed against at least a portion of the exterior surface of the distal end of the feeding tube to form a first balloon structure; and

wherein the first balloon structure is in fluid communication with the first inflation lumen and extends beyond the distal end when the balloon structure is inflated; and

a second overlapping segment integrally formed with and extending from the proximate end of the feeding tube, the second overlapping segment surrounding the proximate end of the feeding tube to form a second balloon structure in fluid communication with a second inflation lumen.
