Abstract

A device for treating obesity by limiting absorption of food through a wall of a duodenum of a patient including a sleeve inserted into the duodenum of a patient. The sleeve includes a plurality of first blocking areas and a plurality of first food absorption areas, the first blocking areas providing duodenum wall covers to prevent food absorption through the duodenum wall and the first blocking areas together defining a first total blocking area. The first food absorption areas providing access to the duodenum wall to enable food absorption through the duodenum wall and the first food absorption areas together defining a first total absorption area.

Claims

1. A kit comprising first and second devices for treating obesity by progressively limiting absorption of food through a wall of a duodenum of a patient, the kit comprising:

a first device having a first sleeve configured and dimensioned for insertion into the duodenum of the patient for a first treatment of obesity, the first sleeve having a proximal portion, a distal portion and an intermediate portion between the distal and proximal portions, the first sleeve including a plurality of first blocking areas and a plurality of first food absorption areas along a length thereof, the first blocking areas providing duodenum wall covers to prevent food absorption through the duodenum wall and the first blocking areas together defining a first total blocking area, the first food absorption areas providing access to the duodenum wall to enable food absorption through the duodenum wall and the first food absorption areas together defining a first total absorption area; and

a second device having a second sleeve configured and dimensioned for insertion into the duodenum of the patient for a second treatment of obesity, the second sleeve having a proximal portion, a distal portion and an intermediate portion between the distal and proximal portions, the second sleeve including a plurality of second blocking areas and a plurality of second food absorption areas along a length thereof, a size of individual second blocking areas being greater than a size of individual first blocking areas, the second blocking areas providing duodenum wall covers to prevent food absorption through the duodenum wall and the second blocking areas together defining a second total blocking area, the second food absorption areas providing access to the duodenum wall and together defining a second total absorption area to enable food absorption through the duodenum wall, wherein the second total blocking area is greater than the first total blocking area and the second total absorption area is less than the first total absorption area due to the size of the individual second blocking areas being greater than the size of individual first blocking areas to thereby enable less absorption in the second treatment to progressively treat obesity by progressively limiting food absorption;

wherein the first blocking areas include a first plurality of spiral sections and the second blocking areas include a second plurality of spiral sections, the first plurality of spiral sections positioned within a first porous covering material which overlies the first plurality of spiral sections and the second plurality of spiral sections positioned within a second porous covering material which overlies the second plurality of spiral sections.

2. The kit of claim 1, wherein the first food absorption areas include a first plurality of pores formed in the first porous covering material of the first sleeve and the second food absorption areas include a second plurality of pores formed in the second porous covering material of the second sleeve.

3. The kit of claim 2, wherein a number of pores in the first plurality of pores is greater than a number of pores in the second plurality of pores.

4. The kit of claim 2, wherein a size of the pores in the first plurality of pores is greater than a size of the pores in the second plurality of pores.

5. The kit of claim 1, wherein a width of the spiral sections of the first plurality of spiral sections is less than a width of the spiral sections of the second plurality of spiral sections.

6. The kit of claim 1, wherein a pitch of the spiral sections of the first plurality of spiral sections is greater than a pitch of the spiral sections of the second plurality of spiral sections.

7. A method for treating obesity comprising:

a) providing a first sleeve having a first series of axially spaced blocking areas and a first series of axially spaced non-blocking areas;

b) inserting the first sleeve into a duodenum;

c) leaving the sleeve in the duodenum so that food absorption through a wall of the duodenum is blocked by the first series of axially spaced blocking areas and allowed by the first series of axially spaced non-blocking areas to provide a first treatment;

d) removing the first sleeve and inserting into the duodenum a second sleeve having a second series of axially spaced blocking areas and a second series of axially spaced non-blocking areas to provide a second treatment, a size of individual blocking areas of the second series of axially spaced blocking areas being different than a size of individual blocking areas of the first series of axially spaced blocking areas, wherein a total blocking area of the second sleeve is different than a total blocking area of the removed first sleeve; and

e) leaving the second sleeve in the duodenum so that food absorption through a wall of the duodenum is blocked to a different extent in the second treatment due to the different sizes of the individual blocking areas of the first and second series of axially spaced blocking areas to progressively treat obesity.

8. The method of claim 7, further comprising the step of removing the second sleeve after a period of time.

9. The method of claim 8, further comprising the step of after removing the second sleeve, inserting a third sleeve into the duodenum, the third sleeve having a total blocking area different than the total blocking area of the second sleeve due to a size of individual blocking areas of the third sleeve being different than the size of the individual blocking areas of the second series of axially spaced blocking areas.

10. The method of claim 7, wherein the total blocking area of the removed first sleeve is less than the total blocking area of the second sleeve.

11. The method of claim 7, wherein the total blocking area of the removed first sleeve is greater than the total blocking area of the second sleeve.
