An endoscope or other medical device includes a number of lumens positioned in an outer shaft. The lumens are formed as a multiple lumen assembly. In one embodiment, individual lumens are connected to each other with a sheet or webbing material. The lumen assembly is rolled or folded along its length for incorporation into the outer shaft of the endoscope or the medical device. The sheet or webbing material may be notched or perforated to facilitate folding the lumen assembly and/or separating the individual lumens from the lumen assembly.
1. A multi-lumen assembly, comprising: an outer shaft configured for insertion into a natural body lumen of a patient and having a central opening defining a first diameter;a flexible sheet of material configured to transition between a first planar configuration and a second configuration, wherein,
1. A multi-lumen assembly, comprising: an outer shaft configured for insertion into a natural body lumen of a patient and having a central opening defining a first diameter;a flexible sheet of material configured to transition between a first planar configuration and a second configuration, wherein, in the first configuration, the flexible sheet of material defines a width larger than the first diameter and the flexible sheet of material includes a single, flat region connecting a first circular portion and a second circular portion, and when in the second configuration, the flexible sheet of material defines a width smaller than the first diameter and is configured to be received within the central opening; anda plurality of lumens fixedly attached to the sheet of material and configured to be received within the central opening. 2. The multi-lumen assembly of claim 1, wherein each of the plurality of lumens is adhesively secured to the sheet of material. 3. The multi-lumen assembly of claim 1, wherein each of the plurality of lumens is extruded as a one-piece assembly with the sheet of material. 4. The multi-lumen assembly of claim 1, wherein the sheet of material includes a number of perforations. 5. The multi-lumen assembly of claim 1, wherein the sheet of material includes a notch that penetrates less than an entire thickness of the sheet of material. 6. The multi-lumen assembly of claim 1, wherein at least one of the plurality of lumens is formed of a material different than a material of at least one other of the plurality of lumens. 7. The multi-lumen assembly of claim 1, wherein at least one of the plurality of lumens is formed of a material different than a material of the sheet of material. 8. The multi-lumen assembly of claim 1, further including: a working channel lumen surrounded by the sheet of material and configured to be received within the central opening. 9. The multi-lumen assembly of claim 1, further comprising: a lumen extension configured to cooperate with at least one of the plurality of lumens. 10. The multi-lumen assembly of claim 9, wherein the lumen extension includes a plug configured to be operatively coupled to a distal end portion of the at least one of the plurality of lumens. 11. The multi-lumen assembly of claim 10, further including a length of tubing extending from the plug. 12. The multi-lumen assembly of claim 1, wherein at least some of the plurality of lumens include an internal diameter larger than an internal diameter of each of a remainder of the plurality of lumens. 13. The multi-lumen assembly of claim 1, wherein at least some of the plurality of lumens include an inner layer and an outer layer, and the inner layer is formed of a first material and the outer layer is formed of a second material different than the first material. 14. The multi-lumen assembly of claim 1, wherein a portion of the sheet of material disposed in between adjacent lumens of the plurality of lumens includes a longitudinally extending cut. 15. The multi-lumen assembly of claim 14, wherein the longitudinally extending cut extends only partially through a thickness of the sheet of material. 16. The multi-lumen assembly of claim 1, wherein the sheet of material includes a durometer value different than a durmoeter value of a wall of one of the plurality of lumens. 17. The multi-lumen assembly of claim 1, wherein a durometer value of a wall of one of the plurality of lumens is different than a durometer value of a wall of another one of the plurality of lumens. 18. A multi-lumen assembly, comprising: an outer shaft configured for insertion into a natural body lumen of a patient and having a central opening defining a first diameter; anda plurality of lumens fixedly attached to a flexible sheet of material and configured to be received within the central opening;wherein the flexible sheet of material is configured to transition between a first planar configuration and a second configuration, wherein, in the first configuration, the flexible sheet of material defines a width larger than the first diameter and, when in the second configuration, the flexible sheet of material defines a width smaller than the first diameter, is configured to be received within the central opening, and is configured so that an outermost surface of the plurality of lumens protrudes into the central opening further than a portion of the flexible sheet of material disposed between adjacent lumens, and wherein a first lumen of the plurality of lumens is circular and includes a first outer diameter and a second lumen of the plurality of lumens is circular and includes a second outer diameter different than the first outer diameter. 19. The multi-lumen assembly of claim 18, wherein when the flexible sheet of material is in the second configuration, the plurality of lumens contact the portion of the sheet of material disposed between adjacent lumens at a location the plurality of lumens are fixedly attached. 20. A multi-lumen assembly, comprising: an outer shaft configured for insertion into a natural body lumen of a patient and having a central opening defining a first diameter;a flexible sheet of material configured to transition between a first planar configuration and a second configuration, wherein, in the first configuration, the flexible sheet of material defines a width larger than the first diameter and, when in the second configuration, the flexible sheet of material defines a width smaller than the first diameter and is configured to be received within the central opening;a plurality of lumens fixedly attached to the flexible sheet of material and configured to be received within the central opening, wherein the flexible sheet of material includes two free ends and in the first configuration each of the free ends is one of the plurality of lumens; anda working channel lumen surrounded by the flexible sheet of material and configured to be received within the central opening, wherein when the flexible sheet of material is in the second configuration, a gap is located between the working channel lumen and the flexible sheet of material.
