    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: An intravascular stent especially suited for implanting in curved arterial portion. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The cells are adapted to provide radial support, and also provide longitudinal flexibility after expansion. The cells also provide increase coverage of a vessel wall. Loops in the stent are disposed and adapted to cooperate, so that after expansion of said stent within a curved lumen, the stent is curved and cells on the outside of the curve open in length, but narrow in width, whereas cells on the inside of the curve shorten in length, but thicken in width to maintain a density of the stent element area which is much more constant than otherwise between the inside and outside of the curve.; The stent also minimizes flaring out by eliminating free loops of the radially supporting circumferential bands of loops.

    摘要: An expandable helical stent is provided, wherein the stent may be formed of a main stent component and a securement. The main stent component is formed from a flat strip having one or more undulating side bands (401, 402) that may be connected to form geometrically shaped cells (430) and are helically wound to form a stent. The helical coils of the main stent component may be spaced apart or nestled to each other. The nestling of the undulation of adjacent helical windings contributes to maintaining the tubular shape and uniformity of the helically coiled stent. Alternatively, the flat strip may comprise a single undulating pattern. At the ends of the main stent component are end bands (407), which when wound, form a cylindrical ring. In one embodiment, one or more struts of the main stent component may have a width sufficient to include one or more fenestrations. The fenestrated struts may be connected by loops or turns wherein the material is narrower than that of the fenestrated struts to provide enhanced flexibility. The helical tubular is maintained with a securement.

    摘要: An expandable stent is provided, wherein the stent is advantageously formed of at least one amorphous metal alloy and a biocompatible material. The stent is formed from flat metal in a helical strip which is wound to form a tubular structure. The tubular structure is not welded but rather is wrapped or coated with a biocompatible material in order to maintain the amorphous metal in its tubular configuration. Said stent can be balloon expanded or self expanding.

    摘要: An intravascular stent (fig. 10) especially suited for implanting in curved arterial portions. The stent (fig. 10) is formed of intertwined meander patterns forming triangular cells (804). The triangular cells (804) are adapted to provide radial support, and longitudinal flexibility after expansion. The triangular cells (804) provide increased coverage of a vessel wall. The stent (fig. 10) can have different portions adapted to optimize radial support or to optimize longitudinal flexibility. The stent (fig. 10) is curved and cells on the outside of the curve open in length, but narrow in width whereas cells on the inside of the curve shorten in length but thicken in width to maintain a density of stent element area which much more constant than otherwise between the inside and the outside of the curve. As a result, when the stent is coated with a medicine the more constant density of stent elements results in an even dose being applied to the inside wall of the lumen, avoiding the possibility that a toxic dose be supplied at one area while a less than effective dose is applied to another area.

    摘要: A drug-coated stent and a method for fabricating the stent are disclosed. The stent has an originally flat pattern and connection points where the sides of the flat pattern are joined. The method includes the steps of a) cutting a stent pattern into a flat piece of metal thereby to produce a metal pattern, b) spraying the flat metal stent pattern with a polymer and a drug, c) deforming the metal pattern so as to cause two opposing sides to meet, and d) joining the two opposing sides at least at one point. Substantially no portion of the stent projects into the lumen of the stent when the stent is expanded against the internal wall of a blood vessel.

    摘要: An expandable helical stent with a securement is provided. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristic. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other. The nestling of the undulation of adjacent helical coils contributes to maintaining the tubular shape of the helically coiled stent. In addition, the nestling of helical coils may prevent the polymer layer from sagging at any point between cycles of the helical coils.
