    摘要： An apparatus, system and method for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The apparatus and method, which are appropriate for cardiovascular and peripheral vessels, use a pulling member and a spring member, for example a compression spring, to oscillate a drilling component. The drilling component at the distal end of the catheter tip has combined longitudinal stiffness for penetrating a total or partial occlusion and high axial (lateral) flexibility to improve deliverability and crossability of a catheter through a partially occluded vessel or a tortuous vessel, and may taper distally. The system of the invention includes the apparatus and a control unit to permit adjustment of the frequency or amplitude of oscillation of the drilling component. Also provided is a method for oscillating a drilling component using a pulling member and a spring member and a method of traversing an occlusion.

    摘要： A serpentine coiled ladder stent (30) is provided, in which the coil is formed from a wound strip of cells (37), wherein the sides of the cells are serpentine. Thus, the stent is comprised of a strip helically wound into a series of coiled windings (31), wherein the strip is formed of at least two side bands (34,35) connected to each other, for example by a series of cross struts (36). The cross struts may be positioned slightly askew. Each side band is formed in a serpentine pattern comprising a series of bends, wherein upon expansion of the stent, the bends of the side bands open to increase the length of each of the individual cells in the helical direction, thereby lengthening the strip in the helical direction to allow the stent to expand without any significant unwinding of the strip.
