  • Methods, devices, systems and computer program products for oscillating shafts using real time 3D ultrasound
    Patent number: 7329225
    Abstract: An oscillating shaft is scanned to provide images including the oscillating shaft in vivo in real-time with a real-time three-dimensional (3D) ultrasound scanner. An interventional device can be guided in vivo using an ultrasound scanner and includes a sheath having a bore therethrough from a proximal portion to a spaced-apart distal portion. A shaft has a proximal portion and a spaced-apart distal portion and is configured for insertion into the bore of the sheath. A vibrator is coupled to the proximal portion of the shaft and is configured to cause the distal portion of the shaft to oscillate at a shaft frequency. An isolator is coupled to the proximal portion of the sheath and to the vibrator, wherein the isolator is configured to reduce damping of an oscillation of the shaft by the sheath.
