    摘要： The invention is directed to a catheter system having an ultrasonic delivery device, a dilatation balloon, and a stent. The ultrasonic distal head is used to ablate a lesion permitting the dilation balloon to cross the lesion for dilatation and for delivering the stent to the lesion. A catheter body includes a first lumen for dilatation balloon expansion control fluid, and a second lumen for the guide wire. The ultrasonic distal head includes a guide wire aperture large enough to permit complete retraction of the guide wire so that the guide wire may be replaced with another while the catheter remains in place within the vasculature of the patient.

    摘要： The ultrasonic angioplasty transmission wire for use in an ultrasonic angioplasty device comprises an inner layer of a first ultrasound transmitting material, and at least one outer coaxial shell or tube of a second ultrasound transmitting material different from the first ultrasound transmitting material. The first inner layer and one or more of the outer coaxial shells or tubes can be formed of ultrasound transmitting metal compositions such as stainless steel, nickel-titanium, or aluminum, or other similar suitable ultrasound transmitting metals. In one embodiment, the first inner layer is formed of a nickel-titanium alloy, and at least one outer coaxial shell or tube is formed of stainless steel. In another embodiment, the first inner layer is formed of nickel-titanium alloy, a first outer coaxial shell or tube is formed of stainless steel, and a second outer coaxial shell or tube is formed of the nickel-titanium alloy.

    摘要： The present invention is directed to an ultrasonic catheter for delivering ultrasonic energy to a treatment location within a patient's body. In a preferred embodiment, the catheter has proximal and distal portions, the distal portion having an outer tubular member. The catheter, preferably, the distal outer tubular member, is formed, at least in part, of a polymeric material blend having a flexural modulus of elasticity less than about 150 ksi.

    摘要： A separate deliverable embolic protection device filter that attaches to a helical coil at a distal end of a conventional guide, for use in a blood vessel when an interventional procedure is being performed to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filter assembly with a proximal end and a distal end, and a guide wire connector attached to the distal end of the filter assembly. The guide wire connector is able to couple with the helical coil of the guide wire. A restraining sheath placed over the filter assembly in a coaxial arrangement maintains the filter assembly in a collapsed position and delivers the filter assembly separately to the helical coil of the guide wire, and then the guide wire connector is joined to the helical coil. Alternatively, the guide wire can include a rotatable coil section forming a portion of the distal tip coil on the guide wire which is adapted to be coupled to the filter assembly. This arrangement allows the filter assembly to be rotatably mounted onto the guide wire.
