    摘要： In one embodiment, an ultrasound imaging assembly (80) includes a housing (82) having a longitudinal axis (88), a proximal end (86), and a distal ending (84) defining a receptacle (90). The imaging assembly includes a transducer package (60) having a central axis (62) and an imaging surface (66) positioned at a desired angle (106) relative to the central axis. The transducer package is at least partially disposed within the receptacle so that the central axis is generally perpendicular to the longitudinal axis. Such a configuration permits a relatively large percentage of the ultrasound signal to pass through a sheath (120) surrounding the imaging assembly and reduces assembly-to-assembly variations.

    摘要： A catheter assembly includes an elongate catheter body having a proximal end and a distal end with a drive cable disposed therein, the drive cable having a proximal end and a distal end, and rotatable relative to the catheter body. A first electro-magnetic element is disposed proximate the distal end of the catheter, and a second electro-magnetic element disposed proximate the distal end of the drive cable and in electrical communication with an operative element mounted at the end of the drive cable, the first and second electro-magnetic elements forming an inductive coupler. The catheter assembly can include various other distal operative elements, which are in communication with corresponding proximal operative elements via transmission lines embedded within the wall of the catheter body.

    摘要： The present invention provides exemplary ultrasound lucent apparatus and methods for use in a wide range of invasive imaging and surgical procedures. In one exemplary embodiment, an apparatus (10) comprises an elongate wire body (12) having an outer surface and a longitudinal axis (18). The wire body includes a plurality of corner reflectors (22) disposed on an embossed portion (20) of the outer surface. The wire body is adapted to be inserted into a body lumen or a patient vasculature. In this manner, use of corner reflector technology enhances the ultrasound reflective nature to increase the acoustical reflectivity of the wire body.

    摘要： Rotating element catheters and catheter assemblies employ clutch assemblies for preventing rotational energy from being transmitted from a motor drive unit to the catheter element under defined circumstances. The catheter assembly includes an elongate member in which there is disposed a rotatable catheter drive cable. The catheter drive cable may have an operative element, e.g., an ultrasonic transducer or an artherctomy blade, distally mounted thereon for providing diagnostic or therapeutic functions to the physician. To control the rotation of the catheter drive shaft, the clutch assembly is configured such that the catheter drive shaft is operated in a drive mode (i.e., it is allowed to rotate) and in a release mode (i.e., it is prevented from rotating). The clutch assembly includes a driver member and a driven member, one of which is magnetic and the other of which is ferrous. The magnetic and ferrous members are arranged in relation to each other, e.g., concentrically, such that a magnetic relationship is created therebetween, which is not overcome when an applied torque does not exceed a critical magnitude, but is overcome when the applied torque exceeds the critical magnitude.

    摘要： The present invention provides ultrasound imaging catheters, systems and methods for their use which will be particularly useful to monitor the positioning of ablation catheters. In one embodiment, an imaging catheter (10) includes a catheter body (11) having a distal end (12), a proximal end (14) and a longitudinal axis (16). A transducer (20) is rotatably coupled to the distal end. The transducer has an axis of rotation (24) that is at a non-zero angle relative to the catheter body longitudinal axis. Such a configuration provides an exemplary side-looking imaging catheter.
