INTRAVASCULAR ULTRASOUND IMAGING SYSTEM WITH SLIP RING INTERFACE AND ASSOCIATED DEVICES, SYSTEMS, AND METHODS

摘要

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.
