1-24. (canceled)
An endoscopic instrument assembly, comprising:
- an endoscope including a lumen, wherein the lumen includes:
- a first portion having a substantially circular cross-sectional shape;
- a second portion having a substantially circular cross-sectional shape;
- and
- a third portion having a substantially non-circular cross-sectional shape, wherein the third portion is disposed between the first portion and the second portion;
- and
- a plurality of instruments disposed within the lumen, wherein a combined shape of at least a portion of the plurality of instruments is complementary with the substantially non-circular cross-sectional shape of the third portion.
An endoscopic instrument assembly, comprising:
- an endoscope including a lumen, wherein the lumen includes:
- a first portion having a first cross-sectional shape;
- a second portion having a second cross-sectional shape;
- and
- a third portion having a third cross-sectional shape different than the first and second cross-sectional shapes;
- and
- a plurality of instruments disposed within the lumen, wherein a combined shape of at least a portion of the plurality of instruments is complementary with the third cross-sectional shape of the third portion.
An endoscopic instrument assembly, comprising:
- an endoscope including a lumen, wherein the lumen includes:
- a first portion having a substantially circular cross-sectional shape;
- a second portion having a substantially circular cross-sectional shape;
- and
- a third portion having a substantially non-circular cross-sectional shape, wherein the third portion is disposed between the first portion and the second portion and is rotatable relative to the first portion and the second portion;
- and
- a control member configured to rotate the third portion.
The endoscopic instrument assembly of 39, further comprising a plurality of instruments disposed within the lumen, wherein a combined shape of at least a portion of the plurality of instruments is complementary with the substantially non-circular cross-sectional shape of the third portion.
The endoscopic instrument assembly of 39, wherein the third portion includes a plurality of teeth, and wherein the control member includes a gear engagable with the plurality of teeth.
The endoscopic instrument assembly of 39, wherein the control member includes one or more wires disposed around the rotatable third portion.
The endoscopic instrument assembly of 40, wherein the plurality of instruments are distinct from each other.
