    摘要： The present invention provides catheter systems and imaging assemblies using off-aperture electrical connections for ultrasound transducers. In one embodiment, a catheter includes a transducer connection apparatus (10) comprising a washer (12) having a hole (15) therethrough. A transducer element (24) is at least partially disposed within the washer hole. A matching layer (26) is operably attached to the washer and to the transducer element. The washer, transducer element and matching layer provide an electrical connection between the transducer element and the washer. Signals can be sent to and received from the transducer by establishing an electrical connection with the washer.

    摘要： The present invention provides ultrasound transducers, and imaging assemblies and catheters employing such transducers, that provide improved imaging capabilities. In one embodiment, an ultrasound imaging assembly (50) includes a housing having a distal end (56), a proximal end (57) and a longitudinal axis. A transducer element (54) is included having an outer face. The outer face has a first radius of curvature along a first axis and a second radius of curvature along a second axis. The transducer element is operably attached to the distal end to position the first axis to be generally parallel to the longitudinal axis to provide improved cross-plane resolution.

    摘要： A flexible drive cable comprises a flexible cable body, a pair of electrically insulated wires disposed through an axial lumen of the cable body, and a resilient support tube disposed over the wire pair. The resilient support tube provides support for the wire pair to help the wire pair recover from bending and deformation which may occur during storage or use of the drive cable. The support tube is usually liquid impermeable to maintain an air gap around the wire pair. The air gap improves shielding and maintains a constant overall impedance across the drive cable. The drive cable may be combined with an ultrasonic transducer at its distal end to form an ultrasonic transmission core.
