  • System and method for inertial magnetic resonance elastography driver for use with interventional medical device
    Patent number: 9173589
    Abstract: A system and method for performing a magnetic resonance elastography (MRE) procedure using an MRI system to monitor operation of a medical device performing a medical procedure. The driver system includes a housing, a port located in the housing and connected to a driving power, and an inertial driver moved within the housing by the driving power. A passage is formed in the housing and extends from a first opening in the housing, through the inertial driver, and to a second opening in the housing. The inertial driver receives a medical device extending through the passage and engages the medical device to impart oscillatory motion thereto as the inertial driver is moved by the driving power. The imparted oscillatory motion travels along the medical device as a waveguide to deliver the oscillatory motion to tissue receiving the medical procedure to perform the MRE procedure.
