Claim 0:
1. A steerable catheter, comprising:
a catheter body having a tool channel extending from a proximal end to a distal end along a longitudinal axis of the catheter body;
a positioning mechanism configure to be coupled with an imaging device and to be slidably inserted into and/or withdrawn from the distal end of the catheter body through the tool channel,
wherein the catheter body has an anti-twist feature configured to interlock the catheter body and the imaging device at the distal end of the catheter body so as to prevent rotation of the imaging device within the tool channel and/or prevent twisting of the distal end of the catheter body,
wherein the anti-twist feature includes one or more bumps that are molded portions of the catheter body protruding radially inward from the surface of the tool channel and tapering in the lengthwise direction from the distal end toward the proximal end of the catheter body, and
wherein the positioning mechanism includes a housing portion made of an elliptical tube attachable to the imaging device, wherein the elliptical tube is configured to be pressure fit against one of the one or more bumps and against inner surface of the tool channel at the distal tip of the catheter body.
