    摘要： A connector assembly is disclosed for coupling a signal wire bundle from a controller console to a hand-operated catheter assembly. The connector includes a female connector component having a cylindrical cavity, wire fingers disposed within the cylindrical cavity, a guide peg disposed on a surface of the cylindrical cavity at a point proximate an opening of the cylindrical cavity, and a central pin disposed on a base surface at a closed end of the cylindrical cavity. The connector also includes a male connector component having a substantially cylindrical shape having a non-uniform transverse cross-section radius. The male connector component comprises a set of signal leads disposed along arcs of a cylindrical surface of the male connector, a slot defined within the male connector's surface is arranged to accept the guide peg of the female connector component and constrain the relative positions of the male connector and female connector during engagement.

    摘要： An ultrasound catheter is described herein for insertion into a cavity such as a blood vessel to facilitate imaging within a vasculature. The catheter comprises an elongate flexible shaft, a capacitive microfabricated ultrasonic transducer, and a sonic reflector. The elongate flexible shaft has a proximate end and a distal end. A capacitive microfabricated ultrasonic transducer (cMUT) is mounted to the shaft near the distal end. The reflector is positioned such that a reflective surface redirects ultrasonic waves to and from the transducer. In other embodiments, the catheter comprises a plurality of cMUT elements and operates without the use of reflectors. In further embodiments, integrated circuitry is incorporated into the design.

    摘要： The present invention provides for pleated bags used with interventional pullback systems, including imaging catheters such as IVUS catheters, as well as for use with other catheters. An exemplary pleated bag of the present invention may be an elongate, sterile bag, having a plurality of pleats near the distal end, and including an orifice proximal to the pleats designed to allow passage of a catheter into the bag. The present invention also provides for a system that includes a pullback device, catheter, and pleated bag. The present invention allows for improved imaging catheter procedures at reduced costs.
