RECIPROCATING INTERNAL ULTRASOUND TRANSDUCER ASSEMBLY

摘要

A device for endoluminal therapeutic and diagnostic ultrasound procedures includes a motor which rotates a drive shaft and ultrasound transducer. In one example, conductors attach to the transducer and extend through a hollow drive shaft. In another example, a bias member conducts electric signals and stores energy. The device includes an operational state in which the motor rotates the drive shaft alternatingly between a first direction and an opposite second direction.
