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

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

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;

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

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

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

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

13. The method of claim 12, further comprising affixing at least a portion of the exterior surface of the 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 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;

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

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

wherein the 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 overlapping segment sealed against at least a portion of the exterior surface of the distal end of the feeding tube to form a balloon structure; and

wherein the balloon structure is in fluid communication with the inflation lumen and extends beyond the distal end of the feeding tube device when the balloon structure is inflated.
