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; and
a plurality of lumens fixedly attached to the sheet of material and configured to be received within the central opening.

Abstract
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.

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; and a 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. - View Dependent Claims (19)
