Abstract

A waste management system includes a waste transport device and a waste collection device. The waste transport device includes a collection member with a distal end opening having a first cross-sectional area and a proximal end opening having a second cross-sectional area less than the first cross-sectional area, a retention cuff disposed about an outer surface of the collection member, and a first section having a lumen in fluid communication with a lumen of the collection member.

Claims

1. A waste management system, comprising:

a waste transport device, including;

a collection member defining in an expanded configuration a distal end opening having a first cross-sectional area and a proximal end opening having a second cross-sectional area less than the first cross-sectional area, a passage connecting the distal end opening and the proximal end opening tapering from the first cross-sectional area to the second cross-sectional area;

a retention cuff disposed about an outer surface of the collection member; and

a first section having a lumen in fluid communication with a lumen of the collection member; and

a waste collection device.

2. The system according to claim 1, wherein the first section has a cross-sectional shape at a proximal end different from a cross-sectional shape at a distal end.

3. The system according to claim 2, wherein the cross-sectional shape at the proximal end is circular and the cross-sectional shape at the distal end is oval.

4. The system according to claim 1, wherein the first section has an hourglass-shaped configuration.

5. The system according to claim 1, wherein the collection member and the first section are formed together into a single member.

6. The system according to claim 5, wherein a distal end of the single member is folded over at the collection member distal end opening to form a rolling portion, the retention cuff attached to the rolling portion.

7. The system according to claim 5, further comprising a placement tool including an end piece with a cross-sectional area similar to the second cross-sectional area.

8. The system according to claim 7, wherein the placement tool end piece has a greater rigidity than a rigidity of the collection member, the end piece collapsing the collection member from the first cross-sectional area to the second cross-sectional area upon movement along the collection member toward the rolling portion.

9. A waste management system, comprising:

a waste transport device, including;

a collection member defining in an expanded configuration a distal end opening having a first cross-sectional area and a proximal end opening having a second cross-sectional area less than the first cross-sectional area, a passage connecting the distal end opening and the proximal end opening tapering from the first cross-sectional area to the second cross-sectional area;

a retention cuff disposed about an outer surface of the collection member; and

a first section having a distal end connected to a proximal end of the collection member; and

a waste collection device.

10. The system according to claim 9, wherein the first section has a wall thickness less than a wall thickness of the collection member.

11. The system according to claim 9, wherein the first section includes a material different from a material of the collection member.

12. The system according to claim 9, wherein a proximal end of the first section has a circular cross-sectional shape and the distal end of the first section has an oval cross-sectional shape.

13. The system according to claim 9, wherein the first section includes a plurality of inflatable ribs or rings.

14. The system according to claim 9, the waste transport device further comprising a second section having a distal end connected to a proximal end of the first section.

15. The system according to claim 14, the second section including a flush lumen disposed along a length thereof.

16. The system according to claim 15, wherein the flush lumen comprises a plurality of spaced apart apertures along a length thereof.

17. A waste transport device, comprising:

a distal section defining in an expanded configuration a distal end opening having a first cross-sectional area and a proximal end opening having a second cross-sectional area less than the first cross-sectional area, a passage connecting the distal end opening and the proximal end opening tapering from the first cross-sectional area to the second cross-sectional area, the distal section including an inflatable retention cuff;

a proximal section including a flush lumen, a connector coupled to a proximal end of the proximal section; and

an intermediate section connecting the proximal section to the distal section, the intermediate section including a transitioning cross-sectional shape from a proximal end to a distal end.

18. The device according to claim 17, wherein the intermediate section has an oval cross-section at the proximal end and a circular cross-section at the distal end.

19. The device according to claim 17, further comprising an inflation lumen in fluid communication with the inflatable retention cuff and a sampling lumen having a distal end adjacent the distal end opening of the distal section.

20. The device according to claim 17, wherein the flush lumen includes a plurality of apertures spaced apart along a longitudinal axis of the proximal section.
