Abstract

Abstract A two stage device for delivering an elongated member to the upper gastrointestinal tract consisting of an outer gelatin pharmaceutical capsule which dissolves in the stomach, an inner open ended capsule contained in said outer capsule and being nonsoluble in the gastro-intestinal tract and having walls inwardly deflectable under peristaltic action of the upper gastro-intestinal tract in the absence of the outer capsule and carrying a weight and a portion of the elongated member. The device being used to deliver cord or tubing at least as far as the duodenum where the carrier separates from the elongated member and passes harmlessly out with the stool. The elongated member as a tube carries medicines, other liquids or gas to the duodenum, and as a yarn is retrieved and examined for diagnosing infection, parasites and other disorders.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 285 words
A carrier system for delivery of an end of an elongated member to the upper gastrointestinal tract comprising: a. an outer gelatin pharmaceutical capsule dissolvable in the upper gastrointestinal tract from the normal presence of moisture and warmth and having an opening in one end thereof; b. an inner capsule enclosed by said outer capsule having an open end bstantially coaxially aligned with the opening of said outer capsule, and being non-soluble in said gastrointestinal tract and completely contained within said outer capsule, and having inwardly deflectable walls collapsible in the absence of said outer capsule by peristaltic action present in the upper gastrointestinal tract for lightly grasping the element of paragraph (d) below between the edges of the walls: c. a weight, non-dissolvable in the upper gastrointestinal tract, carried in the bottom portion of said inner capsule and providing structural support to the walls of the inner capsule at said bottom portion so that said inner capsule is of sufficient bulk to be readily advanced by peristaltic action through the stomach; d. an elongated flexible element releasably connected to said inner capsule and having a first position substantially contained within said inner and outer capsules for playing out of said capsule openings to a second distended position within said gastrointestinal tract, said inner capsule containing said elongated element which is adapted for remaining after said outer capsule has dissolved and until said inner capsule has moved to the duodenum; and e. said elongated element and said inner capsule adapted for remaining connected during delivery of the distal end of said element to the duodenum, and said inner capsule adapted for being releasable from said element in the duodenum upon manually withdrawing said elongated element.
Claim 2
Dependent Claim 285 words
A carrier system for delivery of an end of an elongated member to the upper gastrointestinal tract comprising: a. an outer gelatin pharmaceutical capsule dissolvable in the upper gastrointestinal tract from the normal presence of moisture and warmth and having an opening in one end thereof; b. an inner capsule enclosed by said outer capsule having an open end bstantially coaxially aligned with the opening of said outer capsule, and being non-soluble in said gastrointestinal tract and completely contained within said outer capsule, and having inwardly deflectable walls collapsible in the absence of said outer capsule by peristaltic action present in the upper gastrointestinal tract for lightly grasping the element of paragraph (d) below between the edges of the walls: c. a weight, non-dissolvable in the upper gastrointestinal tract, carried in the bottom portion of said inner capsule and providing structural support to the walls of the inner capsule at said bottom portion so that said inner capsule is of sufficient bulk to be readily advanced by peristaltic action through the stomach; d. an elongated flexible element releasably connected to said inner capsule and having a first position substantially contained within said inner and outer capsules for playing out of said capsule openings to a second distended position within said gastrointestinal tract, said inner capsule containing said elongated element which is adapted for remaining after said outer capsule has dissolved and until said inner capsule has moved to the duodenum; and e. said elongated element and said inner capsule adapted for remaining connected during delivery of the distal end of said element to the duodenum, and said inner capsule adapted for being releasable from said element in the duodenum upon manually withdrawing said elongated element.
Claim 3
Dependent Claim 17 words
A device as described in claim 1 wherein said elongated element is a flexible line of yarn.
Claim 4
Dependent Claim 36 words
A device as described in claim 1 including radiopaque markers attached to the elongated element at selected intervals so that the position and course of the line in the gastrointestinal tract may be determined by x-ray.
Claim 5
Dependent Claim 61 words
A device as described in claim 1 comprising: a. a first thread connected to said inner capsule; b. the distal end of said elongated element being formed with a knot; and c. the free end of said first thread being connected to said elongated element by said knot and releasable therefrom in the duodenum by manual withdrawal of said elongated element.
Claim 6
Dependent Claim 43 words
A device as described in claim 1 comprising: a. said inner capsule is made from silicone rubber; and b. a second thread connected tO the proximal end of said elongated member, having a length adapted to extend from the mouth through the throat.
Claim 7
Dependent Claim 16 words
A device as described in claim 1 wherein said elongated element is a flexible collapsible tube.
Claim 8
Dependent Claim 71 words
A device as described in claim 6 comprising: a. a length of yarn connected to the distal end of said tube and having a knot formed in its free end. b. a connector thread attached to the upper inner wall of said inner capsule and attached to said length of yarn by said knot; and c. said knot adapted for holding said connector thread until said inner capsule reaches the duodenum.
Claim 9
Dependent Claim 80 words
A device as described in claim 1 comprising: a. said elongated element consisting of a yarn; b. an elongated collapsible tube having substantially the length of said yarn element and being connected thereto along substantially the entire length; c. a connector thread attached to the upper inner wall of said inner capsule and attached to said element consisting of a yarn until said capsule reaches the duodenum where it is adapted for release upon manual withdrawal of said elongated element.
