## Abstract

A device that is inserted through the abdominal wall and into the digestive tract of a human is disclosed. The device may be placed through a method such as percutaneous endoscopic gastrostomy (PEG). The device includes a gastrostomy style structure that provides fluid communication with the external environment of the patient with the internal contents of the stomach. The device is produced with a series of slotted collection channels that preferentially, when connected to a source of negative relative pressure, directs a significant volume of the high calorie fluidic components of the chyme out of the digestive tract, preventing exposure to the absorptive tissues of the digestive tract when simple sugars and carbohydrates are consumed.

## Claims

### Claim 1

A device comprising:
a) a channeled collection element having a longitudinal axis, a distal end and a proximal end, wherein the collection element further comprises a separate distinct lumen sealed at its proximal end and that runs substantially parallel to the longitudinal axis and for substantially the full length of the channeled collection element;
b) at least one slot formed in the channeled collection element, said slot parallel to the longitudinal axis of the channeled collection element and sized to permit entrance into the channeled collection element of solubilized sugars or dispersed starches;
c) a port or a port/valve assembly in fluid communication with the distal end of the channeled collection element;
d) a shaping element for insertion into said separate distinct lumen;
e) at least two inflation elements in fluid communication with said separate distinct lumen; and
f) a plug for sealing said separate distinct lumen at its distal end while the shaping element is contained within said separate distinct lumen.

### Claim 2 (depends on 1)

The device of claim 1 wherein the channeled collection element comprises multiple collection channels and a corresponding number of longitudinal slots formed in each channeled collection element.

### Claim 3 (depends on 2)

The device of claim 2 wherein the multiple channeled collection elements transition to a non-slotted, single channeled collection element portion near the distal end of the channeled collection elements.

### Claim 4 (depends on 2, 3)

The device of claim 2 or 3 wherein the size of the slots range from 0.025 mm to 1.5 mm wide.

### Claim 5 (depends on 4)

The device of claim 4, wherein the size of the slots range from 0.250 mm to 0.850 mm wide.

### Claim 6 (depends on 5)

The device of claim 5, wherein the size of the slots are 0.400 mm wide.

### Claim 7 (depends on 3)

The device of claim 3 wherein the single non-slotted channeled collection element portion contains a bend.

### Claim 8

A method of extracting fluids rich in solubilized sugars and dispersed starches from a patient's gastrointestinal tract comprising the steps of:
a) inserting into the stomach of the patient a device comprising:
i. a channeled collection element having a longitudinal axis, a distal end and a proximal end, wherein the collection element further comprises a separate distinct lumen sealed at its proximal end and that runs substantially parallel to the longitudinal axis and for substantially the full length of the channeled collection element;
ii. at least one slot formed in the channeled collection element, said slot parallel to the longitudinal axis of the channeled collection element and sized to permit entrance into the channeled collection element of solubilized sugars or dispersed starches;
iii. a port or a port/valve assembly in fluid communication with the distal end of the channeled collection element;
iv. a shaping element for insertion into said separate distinct lumen;
v. at least two inflation elements in fluid communication with said separate distinct lumen; and
vi. a plug for sealing said separate distinct lumen at its distal end while the shaping element is contained within said separate distinct lumen;
b) connecting to the port or port/valve assembly in fluid communication with the distal end of the channeled collection element a disposal tube; and
c) withdrawing fluid from the patient's stomach to a point external to the patient through the disposal tube.

### Claim 9 (depends on 8)

The method of claim 8, wherein the channeled collection element comprises multiple collection channels and a corresponding number of longitudinal slots formed in each channeled collection element.

### Claim 10 (depends on 9)

The method of claim 9, wherein the multiple channeled collection elements transition to a non-slotted, single channeled collection element portion near the distal end of the channeled collection elements.

### Claim 11 (depends on 10)

The method of claim 10, wherein the single non-slotted channeled collection element portion contains a bend.

### Claim 12 (depends on 10)

The method of claim 10, further comprising the step of inflating the inflation elements after the step of inserting the device into the patient's stomach but prior to the step of withdrawing fluids from the patient's stomach.

### Claim 13 (depends on 1)

The device of claim 1, wherein one of the at least two inflation elements is located toward the distal end of the channeled collection element and the other of the at least two inflation elements is located toward the proximal end of the channeled collection element.

### Claim 14 (depends on 8)

The method of claim 8, wherein the at least two inflation elements of the device comprises one of the at least two inflation elements being located toward the distal end of the channeled collection element and the other of the at least two inflation elements being located toward the proximal end of the channeled collection element.
