摘要: High torque guidewires and methods for making and using them are provided. A guidewire may include an inner core wire movable relative to an outer jacket. The outer jacket includes proximal and distal ends, a lumen extending there between, thereby defining a longitudinal axis, and one or more helical slots adjacent the distal end. The core wire includes a proximal portion, a distal portion slidably received in the outer jacket lumen and terminating in a curved distal tip that extends from the outer jacket distal end, and one or more pins on the distal portion, each pin slidably received in a respective helical slot in the outer jacket such that axial movement of the core wire relative to the outer jacket causes the pin to slide within the helical slot and rotate the distal tip relative to the outer jacket distal end.

摘要: The present disclosure is directed to multi-segment intraluminal guide wires including an elongate distal portion comprising a first metallic material (e.g., nitinol), an elongate proximal portion comprising a second metallic material (e.g., stainless steel). The distal and proximal portions may be directly joined together end to end by a solid-state weld joint. A diameter of the weld region surrounding the weld joint on either side of the weld joint may be reduced (e.g., ground down) relative to the diameter of the distal and proximal portions of the guide wire on either side of the weld region. A stiffness adjusting sleeve may be disposed over the weld joint so that a transition profile of bending stiffness across the weld region is gradual, rather than abrupt across the distal portion of the guide wire to the proximal portion of the guide wire. A polymer jacket may cover the sleeve and distal portion.

摘要: A guidewire made from a drawn filled tube composite wire is described. The composite wire has a stainless steel outer sheath jacketing a nitinol core wire. The drawn filled tube composite wire is ground at its distal end to expose the nitinol core, which has superelastic and kink resistant properties that are desirable for the distal end of a guidewire. The proximal end of the drawn filled tube is not ground or if ground, the outer sheath of stainless steel is not removed to an extent sufficient to expose the nitinol core.

摘要: A guidewire having a first end and a second end, and comprising two or more guidewire modules. Each guidewire module has a first end and a second end. Each guidewire module is configured to be attachable to a second guidewire module by at least one of: attaching the first end of the guidewire module with the second end of the second guidewire module, and attaching the second end of the guidewire module with the first end of the second guidewire module.

摘要: A guide wire including a core shaft, a coil body that covers an outer periphery of the core shaft, and a distal end joint that joins the core shaft and the coil body, The distal end joint includes tin-zinc based solder. The guide wire has secured joining strength between the core shaft and the coil body no matter the material used for the core shaft and the coil body, and especially when the core shaft and/or the coil body are formed of tungsten.

摘要: One aspect relates to a guidewire system, a measuring system, and a method for manufacturing such guidewire system. The guidewire system includes a guidewire and a surface acoustic wave sensor device. A portion of a surface of the guidewire is coated by the surface acoustic wave sensor device. The surface acoustic wave sensor device may be configured for measuring a pressure change. The surface acoustic wave sensor device includes a piezoelectric substrate and a transducer. A thickness of the surface acoustic wave sensor device perpendicular to a longitudinal direction of the guidewire is smaller than 100 μm.

摘要: Shapeable guide wire devices and methods for their manufacture. Guide wire devices include an elongate shaft member having a shapeable distal end section that is formed from a linear pseudoelastic nickel-titanium (Ni—Ti) alloy that has linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite. Linear pseudoelastic Ni—Ti alloy, which is distinct from non-linear pseudoelastic (i.e., superelastic) Ni—Ti alloy, is highly durable, corrosion resistant, and has high stiffness. The shapeable distal end section is shapeable by a user to facilitate guiding the guide wire through tortuous anatomy. In addition, linear pseudoelastic Ni—Ti alloy is more durable tip material than other shapeable tip materials such as stainless steel.
