Abstract: A torque device for gripping and manipulating a guidewire for advancing the guidewire into a patient's vascular system. The torque device is configured for single-handed use and can be opened for repositioning the torque device relative to the guidewire and closed for gripping the guidewire to prevent axial and rotational movement relative to the guidewire. The torque device grips the guidewire at multiple spaced apart locations on the guidewire.

Abstract: A guidewire for use in intravascular procedures has an elongated core member including a proximal core section having a uniform diameter. One or more parabolic grind profile sections extend distally from the distal end of the proximal core section and provide a linear change in bending stiffness and a high degree of torque to the distal portion of the guidewire.
