    摘要： Apparatus and method are disclosed by which a distal end portion of a wire may be deposited at selected sites in body passageways. The apparatus includes an elongate wire having a distal end section for detachment and delivery to a target location, the wire also having a discontinuity located rearwardly of the distal end section for rupturing when vibrational energy is applied to the wire. Also included is a vibrational energy source couplable to the proximal end of the wire for selectively applying vibrational energy to the wire to travel to the discontinuity and cause detachment of the end section. The discontinuities may take the form of cuts formed in the wire, reduced diameter sections in the wire, adhesive, welded or soldered couplings between the wire and the distal end section, or the wire transitioning from the wire to a large mass disposed on the distal end section.

    摘要： A hybrid catheter guide wire includes an elongate solid body having a tapered distal end over which is disposed a tubular section—about which a catheter may be threaded for guidance to a target location in a vasculature passageway of a body. Cuts are formed either by saw-cutting, laser cutting or etching at spaced-apart locations along at least a portion of the tubular section to increase its lateral flexibility, while maintaining its rotational torquability, and to control the direction and degree of flexure.

    摘要： A hybrid tubular wire includes first and second elongate tubular bodies, fitted end to end, and about which a catheter may be threaded for guidance to a target location in a vasculature passageway of a body. The first elongate body has greater rotational stiffness than the second elongate body, which has greater lateral flexibility. Cuts are formed either by saw-cutting, laser cutting or etching at spaced-apart locations along the length of the second elongate body to increase its lateral flexibility. At least some of the cuts extend through the tubular body to the interior cavity to allow the escape of fluids flowing in the cavity.
