Abstract:
1. An imaging catheter tip, comprising: a housing; a transducer assembly located within the housing in a distal portion of the imaging catheter tip, wherein the transducer assembly comprises a transducer; a motor located within the housing in a proximal portion of the imaging catheter tip, wherein the motor is configured to facilitate oscillation of the transducer of the transducer assembly about a longitudinal axis of the imaging catheter tip; a fill tube disposed between the motor and the housing, wherein the fill tube is configured to deliver acoustic coupling fluid to the distal portion of the imaging catheter tip, wherein the fill tube is configured to restrict the oscillation of the transducer of the transducer assembly about the longitudinal axis of the imaging catheter tip; and a motor holder circumferentially surrounding the motor along the longitudinal axis, wherein the motor holder is configured to fix the motor in a specific position within the housing.
