    摘要: The invention is directed to an guide wire for intraluminal deployment of a medical device within a patient, the guide wire having an elongate core member with an intermediate core section comprising a plurality of contiguous segments in alignment with the longitudinal axis of the core member with alternating flexible and rigid core segments, so that the articulated section bends in a discontinuous, discrete manner when advanced through a curved blood vessel or other body lumen within the patient. When an obstruction on a vessel wall causes the catheter or other coaxial device to be impeded, the guide wire and intermediate core section may alternately be advanced and retracted a short distance through the catheter distal tip causing a “nodding” motion of the catheter tip while the catheter is pushed through the vessel, so as to avoid and bypass the vessel obstruction.

    摘要: The ultrasonic angioplasty transmission wire has regions of reduced cross-sectional diameter to improve flexibility of the ultrasonic angioplasty transmission wire and to compensate for degradation of longitudinal displacement due to acoustic losses along the length of the ultrasonic angioplasty transmission wire. One or more constraining members are disposed on the ultrasonic angioplasty transmission wire at one or more of the regions of reduced cross-sectional diameter where transverse vibration of ultrasonic energy transmitted by the ultrasound transmission wire is amplified, to constrain transverse vibration at these areas to reduce stress and reduce fracturing, while allowing longitudinal movement. The transmission wire has an elongated shaft including, in atomic percent, from about 28 to about 52 percent nickel, from about 48 to about 52 percent titanium, and up to about 20 percent of at least one alloying element selected from the group consisting of palladium, chromium, and hafnium.

    摘要: An intravascular guide wire having two core materials joined together without the use of a connector tube or sleeve, the core materials being stainless steel and psuedoelastic metal alloy, nitinol. The core materials are joined to each other through an intermediate transition piece made essentially of nickel, which is welded on either side to the two core materials. In a multi-segment intravascular guide wire, discrete, high modulus and medium modulus core portions of different materials are welded to a shapeable, low modulus distal core portion made of a third material having a flattened, shapeable section at a most distal end that is not welded to but made from the distal core portion, so the flattened, shapeable section can be deformed to create a steerable tip. Processes such as simultaneous resistance and friction welding can be used to join the core portions.

    摘要: The present invention is directed to an intracorporeal device, preferably a guidewire, and method for making the device. The guidewire of the present invention is formed, at least in part, of a composite elongate core formed, at least in part, of precipitation hardened material. The elongate core members of the present invention will have an ultimate tensile strength and modulus of elasticity greater than the same for an identically dimensioned elongate member formed from superelastic NITINOL alone.

    摘要: A guide wire includes an elongate core section and a flexible member disposed on the distal end, the flexible member including a first wire wound into an inner helical coil in a first direction and a second wire wound into an outer helical coil wrapped about the first helical coil in the opposite direction. The two combined helical coils add stiffness and torque transmission to the guide wire without sacrificing tactile feedback.
