Imaging catheter tip for ultrasound imaging system, has motor located within housing in proximal portion of imaging catheter tip to facilitate oscillation of transducer assembly about longitudinal axis of imaging catheter tip

摘要

#CMT# #/CMT# The tip (26) has a transducer assembly located within a housing in a distal portion of the imaging catheter tip, where the transducer assembly comprises a transducer (38). A motor (34) is located within the housing in a proximal portion of the imaging catheter tip, where the motor is configured to facilitate oscillation of the transducer assembly about a longitudinal axis of the imaging catheter tip. A fill tube (50) is placed between the motor and the housing, where the fill tube delivers acoustic coupling fluid to the distal portion of the imaging catheter tip. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method for using an imaging catheter tip (2) a method for initializing the oscillation of a transducer assembly within an imaging catheter tip. #CMT#USE : #/CMT# Imaging catheter tip for use in ultrasound imaging system (claimed) for intracranial imaging. #CMT#ADVANTAGE : #/CMT# The motor located within the housing in the proximal portion of the imaging catheter tip facilitates oscillation of the transducer assembly about the longitudinal axis of the imaging catheter tip, thus enabling transducer assembly to obtain real-time, three-dimensional ultrasound images by sweeping a two-dimensional slice through a three-dimensional volume. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective side view of the imaging catheter tip. 26 : Imaging catheter tip 34 : Motor 38 : Transducer 46 : Interconnect cable 50 : Fill tube 64 : Proximal transducer fixture.
