Claim 6:
7. A radial ultrasound capsule system comprising:
an ultrasound capsule comprising:
a housing comprising:
a motor compartment comprising:
a proximal face; and
a distal end, wherein the motor compartment has a longitudinal axis; and
a cap configured to seal with the motor compartment in order to form a sensor compartment, the cap includes two orientation pins oriented parallel to a longitudinal axis of the cap less than 180° from each other along an arc of the cap;
 a motor located within the motor compartment, the motor comprises:
 a drive component; and
 a shaft rotatably coupled to the drive component and extending distally from the motor compartment into the sensor compartment, the shaft has a longitudinal axis that is parallel to the longitudinal axis of the motor compartment;
 an ultrasound transducer coupled to the shaft, wherein the ultrasound transducer is located at the same longitudinal position as the two orientation pins;
 a plurality of electrical contacts mounted on the proximal face, wherein at least two of the electrical contacts are electrically coupled to the motor; and
 a rotational electrical coupler comprising:
 a rotational component mechanically coupled to the shaft and electrically coupled to the ultrasound transducer; and
 a stationary component mechanically coupled to the motor compartment and electrically coupled to one or more of the plurality of electrical contacts; and

a catheter comprising:
a proximal end comprising an access port;
a distal end comprising:
a distal face of a same diameter as a proximal face of the ultrasound capsule and coupled to the proximal face of the motor compartment of the housing of the ultrasound capsule and comprising a plurality of electrical contacts; and
a side exit port located proximal from the distal face;
at least one lumen configured to extend from the access port to the exit port;
a ramp located at a distal end of one of the at least one lumen; and
a plurality of electrical connectors accessible from the proximal end of the catheter, wherein the plurality of electrical connectors are connected to at least a portion of the plurality of electrical contacts of the distal face.
