Abstract
Disclosed are embodiments of devices and methods for imaging the inside of a body part, such as a blood vessel. In particular embodiments, a catheter has a chamber within which is a transducer. A wire guide channel extends throughout the length of the catheter. The transducer is rotatable about the wire guide channel and the transducer is driven by a cable or other device that is connected to a motor which is located outside the catheter. In one form, a torque cable connects the transducer to the motor. In other embodiments, a pusher piece having a plurality of lumens is positioned in the catheter. Each of the lumens is sized to receive a cable, wire, and/or flushing fluid. The lumens maintain the orientation and separation of the cables, wires, and/or to flushing fluid.
