description | The present invention generally relates to elongate probe assemblies of sufficiently miniaturized dimensions so as to be capable of navigating tortuous paths within a patient's organs and/or vessels. In preferred forms, the present invention is embodied in automated units which are connectable to a probe assembly having a distally located ultrasound transducer subassembly which enables the transducer subassembly to be positioned accurately by an attending physician and then translated longitudinally (relative to the axis of the elongate probe assembly) within the patient under automated control.
A longitudinal position translator includes a probe drive module and a linear translation module. The probe drive module is coupled operatively to an ultrasonic imaging probe assembly having a distally located ultrasound transducer subassembly in such a manner that longitudinal shifting of the transducer subassembly may be effected. The probe drive module is preferably mounted to the linear translation unit so as to be moveable between a condition whereby longitudinal shifting of the transducer subassembly can be conducted either manually or automatically. When in the automatically-operable condition, the probe drive module will be engaged with a motor-driven screw associated with the linear translation module so as to cause the probe drive module to be longitudinally displaced at a constant motor-driven rate. In this manner, the distally located ultrasound transducer is longitudinally shifted during an ultrasound scan of surrounding intravascular (or other) tissue to thereby allow axially-spaced 360 data sample "slices" of the surrounding tissue to be obtained. The data samples may then be reconstructed into a three-dimensional or other two-dimensional representations of the scanned vessel to assist in diagnosis. |
