Classification: CPC A  G | IPC A  G

Claim 0:
1. A radial ultrasound device comprising:
a catheter comprising a proximal end, a distal end, and a lumen extending from the proximal end to a side exit port adjacent the distal end;
a housing coupled to the distal end of the catheter and having a same diameter as a distal face of the distal end of the catheter, the housing comprising:
a motor compartment comprising:
a proximal face mechanically and electrically coupled to a distal face of the distal end of the catheter; 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;

an ultrasound transducer coupled to the shaft at a longitudinal position collocated with 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.
