摘要： An improved catheter system having an ultrasonic imaging transducer coupled to a drive cable disposed within a lumen of a flexible tubular catheter body. An improvement including a reconfiguration of the ferrites in the hub assembly, such that the need for the gap between the ferrites is removed. A strain relief member is provided to increase the strength of the electrical transmission lines to enable them to withstand the tensile forces caused by either flushing and/or pull-back operations. A device which allows the electrical transmission lines to extend their length when placed in tension may also be employed to provide strain relief to the electrical transmission lines. Another improvement includes a counter-wound coil structure, which may either expand or contract as the drive cable is being rotated to strengthen the drive cable. The distal tip of the catheter body may be redesigned to provide a lumen which allows for the release of flushing fluids through a distal port in the guidewire lumen.

摘要： An improved catheter system having an ultrasonic imaging transducer coupled to a drive cable disposed within a lumen of a flexible tubular catheter body. The distal tip of the catheter body may be redesigned to provide a lumen which allows for the release of flushing fluids through a distal port in the guidewire lumen. The catheter includes a wedge disposed between a primary lumen and a guidewire lumen and a wedge lumen formed in the wedge allows communication between the primary lumen and the guidewire lumen.

摘要： An intravascular filter assembly is disclosed for fragmenting a thrombotic or atherosclerotic occlusion and capturing thrombotic or atherosclerotic debris within a blood vessel. The intravascular filter assembly includes an elongate shaft and an expandable filter coupled to the distal region of the elongate shaft. One or more piezoelectric elements are secured to the elongate shaft at a location proximal of the expandable filter. A conducting wire is attached to the one or more piezoelectric elements and extends toward the proximal end of the elongate shaft. The one or more piezoelectric elements are configured to generate ultrasonic waves when subjected to an electrical voltage to fragment a thrombotic or atherosclerotic occlusion within a blood vessel.

摘要： Systems and methods for transporting and deploying intravascular devices through a body lumen are disclosed. An intracorporeal device in accordance with an exemplary embodiment of the present invention can include an elongate member with a proximal portion defining first, second and third lumens and a distal portion defining a containment lumen. A filter assembly can be disposed within the containment lumen, with a filter wire attached to the filter assembly and extending through the first lumen. A guidewire can be passed through a distal guidewire lumen that extends through the filter assembly. The guidewire can extend through the distal guidewire lumen and through the second or third lumen. With the filter assembly disposed in the elongate member, the guidewire can then be advanced through a patient's vasculature, the filter delivery system advanced through the vasculature over the guidewire and the filter assembly deployed from the containment lumen.
