Abstract
An intravascular ultrasound (IVUS) imaging system is provided. The IVUS imaging system includes an intravascular device including a transducer shaft with an ultrasound transducer at a distal end. The IVUS imaging system also includes an interface module removably coupled to the intravascular device. The interface module includes a connector rotatably coupled to a proximal end of the transducer shaft; a motor coupled to the connector; a spinning element coupled to the motor, wherein the spinning element comprises four conductive rings; a stationary element comprising a plurality of brushes, wherein the stationary element is disposed proximate the spinning element such that a different one of the plurality of brushes is in mechanical contact with each of the four conductive rings; and four conductors coupled to the connector and the spinning element such that the stationary element and the intravascular device are in electrical communication.
