可挠支架 The flexible stent
[0002] 本发明一般是关于可扩展性管状结构，其可插入活体的小空间中；更特别地，本发明涉及一种支架结构，其能够在沿其长度上的点实质且重复挠曲，而不产生机械缺陷以及几何上的实质改变。 [0002] The present invention generally relates to scalable tubular structure, which can be inserted into a living body in a small space; More particularly, the present invention relates to a frame structure, and capable of repeated flexing along its length in the substantial point, generating mechanical defects and without substantial changes in geometry.
[0003] 支架是一种管状结构，其为辐射状压缩或卷曲型态，可被插入活体的有限空间中，例如动脉或其它血管；支架在插入后可辐射状扩展以加大其所在之空间。 [0003] The stent is a tubular structure is radially compressed or crimped patterns, can be inserted into a limited space in a living body, such as an artery or other vessel; stent can be radially expanded after insertion to increase the space in which it is . 支架一般可分为球囊型(balloon-expanding，BX)与自扩展型(self-expanding，SX);球囊型支架需要球囊，其通常为输送系统的一部份，以使支架自血管内部扩展以使血管膨胀；自扩展型支架是通过材料、几何形状、或是制造技术的选择，而设计为一旦其被释放至所欲血管中时，便从卷曲状态扩展成扩展状态。 Stents are generally divided into type balloon (balloon-expanding, BX) with a self-expanding type (self-expanding, SX); balloon stents need balloon, which is typically part of a delivery system for the stent from the vessel internal expansion so that the expansion vessel; self-expanding stents are manufactured by a technique selected materials, geometries, or, and once it is designed to be released into the desired blood vessel, begins crimped state to expanded state. 在某些情况中，需要比自扩展型支架的扩张力更高的力量来使受病血管膨胀；在这样的例子中，可能需要使用球囊或类似的装置来辅助自扩展型支架的扩展。 In some cases, we need higher than the self-expanding stent expansion force strength to cause dilation of blood vessels Shoubing; In such an example, it may require the use of a balloon or similar device to assist self-expanding stent is expanded.
[0004] 支架一般是用于治疗血管与非血管疾病。 [0004] The stent is typically for treating vascular and non-vascular diseases. 举例而言，卷曲的支架可被插入阻塞的动脉中，然后扩展以使动脉中的血流恢复；在释放前，支架一般会在导管中保持其卷曲状态；当程序完成时，支架是以扩展状态留在患者动脉内部，而患者的健康、有时是患者的生命便仰赖支架维持其扩展状态的能力。 For example, the crimped stent may be inserted into the blocked artery and then expanded to restore blood flow in the artery; before being released, the stent will generally maintain its rolled state in the conduit; When the procedure is completed, the stent is expanded state left inside the patient artery, and the patient's health, and sometimes life will depend on the patient's ability to maintain its expanded state of the stent.
[0005] 许多现有的支架都是于其卷曲状态中挠曲，以增进支架在例如动脉中的输送，只有极少数支架在展开或扩展后仍可挠曲。 [0005] Many existing stents are crimped in its flexed state, for example, to enhance delivery of a stent in the artery, only a very small deflection of the stent in the expanded or extended still. 然而在展开后，在某些情况中(例如在进行表面股骨动脉的支架诊疗时)，支架会受到实质上的挠曲或弯曲、或是在沿其长度的位置点上产生轴向压缩与重复移位，这会使支架产生严重的应变与疲劳，因而导致支架失效。 However, after deployment, in some cases (e.g., femoral artery during stent surface treatment), the stent will be substantially flex or bend, or to produce an axial compression and repetition on the position of the point along the length thereof shift, which causes the stent serious strain and fatigue, resulting in failure of the stent.
[0006] 支架状结构也存在类似的问题，实例之一为在导管瓣膜输送系统中使用支架状结构与其它构件时，此种支架状结构托住放置在血管中的瓣膜。 When the [0006] stent-like structure, there are similar problems, one example is the use of other stent-like structure with the valve member in a catheter delivery system, such a stent-like structure is placed in a blood vessel hold valve.
[0007] 根据本发明，建构了一种支架或支架状结构，以沿其长度方向上具有不同类型的管状部分；一般而言，其有支柱部分与螺旋部分，其中支柱部分基本上是建构来提供辐射状扩展与径向强度，而螺旋部分基本上是建构来提供重复挠曲以及轴向压缩与扩展。 [0007] According to the present invention, the construction of a stent or stent-like structure, a tubular portion having a different type of direction along its length; in general, it has strut portion and the helical portion, wherein the strut portion substantially to construct providing radial expansion and radial strength, and the spiral portion is substantially repeated flexing, and to provide a construction of an axial compression and expansion. 挠曲与轴向压缩是同时需要的，支架结构才能在处于轴向压缩或扩展状态时，也可以产生重复与实质的挠曲，而在处于挠曲状态时可以同时产生轴向压缩。 Axial compression and flexure is required while, when in the stent structure can be axially compressed or expanded state, it may be repeated to produce substantial deflection, in a deflected condition and in the axial compression may be generated simultaneously. 较佳为，在螺旋部分之间提供支柱部分、或是在支柱部分之间提供螺旋部分；在一较佳实施例中，所述支架是自扩展型支架，而支柱部分与螺旋部分是沿着支架的长度间隔配置。 Preferably the coil portion provided between the pillar portion is provided between the spiral portions of the pillar portion, or; in a preferred embodiment, the stent is self-expanding stent, the strut portion and the coil portion along the length of the stent intervals.

[0009] 根据本发明的另一构想，螺旋部分是由沿着在两个不同支柱部分上的位置之间的支架轴螺旋状延伸的螺旋组件所制成，其中当支架处于其扩展状态时，两个不同的支柱部分周围间隔的距离大于支架周围的约25% (相当于沿支架轴90度的范围)。 [0009] In accordance with another concept of the present invention, the spiral portion of the coil assembly is made of extending helically along the support shaft between the two different locations on the post portion, wherein when the stent is in its expanded state, different distances around two spaced leg portions than about 25% around the holder (corresponding to a range of 90 degrees along the support shaft).
[0010] 根据本发明的另一构想，螺旋部分是由螺旋组件制成，其沿着所述支架的轴，在两个不同的支柱部分上的位置之间螺旋延伸。 [0010] In accordance with another concept of the present invention, the spiral portion is made of a coil assembly, the coil extending between the two different locations on the post portion along the axis of the stent. 在一实施例中，螺旋组件是双向的，其首先延伸于一周围方向中，然后沿着两位置之间的另一方向延伸且具有一尖峰。 In one embodiment, the coil assembly is bidirectional, which extends first in one circumferential direction, and then extends in the other direction between two positions and having a peak.
[0011] 根据本发明的又一构想，支架具有多个轴向上分开的支柱部分，其一般定义了所述支架的管状轴向片段，并建构为可辐射状扩展。 [0011] According to a further idea of ​​the invention, the stent strut portion having a plurality of axially separated on the tubular axial segment generally define the bracket, and may be constructed as radially extended. 一螺旋部分被轴向插置在两支柱部分之间，且所述螺旋部分具有连接于两个支柱部分上周围分开位置之间的多个螺旋组件，且在支架处于扩展状态时，至少部分的螺旋部分具有比支柱部分大的直径。 When a screw portion is axially interposed between two leg portions, and the helical coil portion having a plurality of connecting components between two spaced locations around the upper leg portions, and the stent in an expanded state, at least a portion of the helical portion having a large diameter than the post portion. 在一替代实施例中，在支架处于扩展状态时，至少部分的螺旋部分具有比支柱部分小的直径。 In an alternative embodiment, the stent is in the expanded state, the coil portion at least partially having a smaller diameter than the post portion.
[0012] 在一实施例中，螺旋组件在连接至所述螺旋组件的支柱组件之间卷绕至少90度；在另一实施例中，螺旋组件则在连接至所述螺旋组件的支柱组件之间卷绕至少360度。 [0012] In one embodiment, the coil assembly between the coil assembly is connected to the strut assembly is wound at least 90 degrees; In another embodiment, the coil assembly is connected to the strut assembly of the coil assembly Room wound at least 360 degrees.

[0043] 详细实施方式说明 [0043] Detailed embodiments described embodiment
[0044] 以下参考伴随的图式，对较佳实施例进行详细说明；在整份图式与说明中，相同的参考符号是用来表示相同或类似的部分。 [0044] below with reference to the accompanying drawings, embodiments of the preferred embodiment described in detail; parts throughout the drawings and description, the same reference symbols are used to designate the same or like parts.
[0045] 图1A与图1B是根据本发明第一实施例的支架10的平面图，其分别显示支架10在未扩展状态与在扩展状态。 [0045] FIG 1A and FIG 1B is a plan view of a first embodiment of the stent embodiment of the present invention 10, which brackets 10 are shown in the unexpanded state and the expanded state. 此处所使用的用语“平面图”是用于说明一展开平面图，其可想象为沿着一条与管状支架的轴平行且位于其外部的线来打开所述管状支架；由此可知，在实际的支架中，图1A的顶部边缘将被结合至下方边缘。 As used herein, the term "plan" is a plan view for explaining a deployment, which may be thought of as a parallel along an axis of the tubular stent and is located outside the line of the tubular stent to open; can be seen, the actual stent in FIG. 1A is a top edge bonded to the edge of the bottom.
[0046] 支架10是由与自扩展支架相同的材料所制成，例如本领域中所习知的Nitinol (镍钛合金)。 [0046] The holder 10 is made of the same material with a self-expanding stent, such as those in the conventional known as Nitinol (nickel-titanium). 一般而言，支架是由管材经雷射切割而成，管材的直径约为5_(图1A)，其可接着扩展为直径约8mm(图1B);而在展开之前，其可卷曲至一个适合应用的直径，例如约为3_。 Generally, the stent is formed by laser cutting from a tube, the diameter of the pipe is about 5_ (FIG. 1A), which may then be expanded to a diameter of about 8mm (FIG. IB); and prior to deployment, which may be crimped to a suitable the diameter of the application, for example, approximately 3_. 然而，可知的是本发明可应用于任何类型与大小的支架。 However, it was found that the present invention is applicable to any type and size of the stent.
[0047] 支架10 —般是由支柱部分12与螺旋部分14所制成，其中轴向上对齐的支柱部分12与螺旋部分14交替配置。 [0047] The bracket 10 - is made of strut-like portion 12 and the coil portion 14, aligned in the axial direction wherein the strut portion 12 and the coil portion 14 are alternately arranged. 在一较佳实施例中，支柱部分12是放置在支架10的任一侦U。 In a preferred embodiment, the strut portions 12 are placed on either stent 10 detect a U. 支架部分12在展开时可辐射状扩展，各支柱部分12包括了支柱环16，其具有由波浪形状、沿支架周围前进的支柱组件16a所构成的样式。 Portion 12 may be radially expanded stent when deployed, each strut 12 includes a strut ring portion 16, a pattern having a wave shape, along the circumference of the stent strut assembly 16a forward constituted. 每个支柱组件16a的宽度与支架周围峰-峰间距离相同，而其长度与沿着支架长的峰-峰间距离相同；由此可知支柱环16可以被部分变直(图1B中的垂直伸直)，以加宽支柱组件16a并减少其长度，这就相当于辐射状扩展支架10。 Each strut assembly 16a around the peak width of the stent - the same as the distance between the peaks, and the length of the peak along the length of the stent - the same distance between the peaks; ring struts 16 may be seen to be straightened vertical portion (FIG. 1B straight), to widen the strut assembly 16a and reduce its length, which is equivalent to radially expand the stent 10. 较佳为，制成支架10的材料可使支柱组件16a在辐射状扩展状态中保留其部分波浪形状。 Preferably, the stent material may cause the strut assembly 10 to retain its portion 16a in a wavy shape radially expanded state. 在释放时，支架会被卷曲并与一导管相称，然后在导管被插入血管后扩展而从导管移出。 Upon release, the stent is crimped and are commensurate with a catheter, and expanded after the catheter is removed from the catheter inserted into the blood vessel.
[0048] 每个螺旋部分都是由多个肩并肩的螺旋组件18所组成，其各沿着支架10的轴螺旋卷绕；螺旋部分14在展开时可辐射状扩展，而在一展开状态时是可压缩、可扩展且可弯曲的。 Helical portion 14 may radially expand when deployed, and in a deployed state; [0048] Each of the spiral section is a plurality of side by side by a coil assembly 18 consisting of, each of the spirally wound along the axis of stent 10 It is compressible, extensible and bendable. 螺旋组件18可连接在不同支柱部分12的支柱组件16a相对的各别波浪部分之间，在此实施例中，各螺旋组件18会沿着支架10表面的产生完全旋转，然而，其也可以产生一部分旋转或多于一次的旋转。 Coil assembly 18 may be connected between the respective wave portions 16a opposing a different strut strut assembly portion 12, in this embodiment, each of the coil assembly 18 will be completely rotated in the generated surface of the stent 10, however, it may also be generated more than one part of the rotation or rotation. 螺旋部分最好是建构为可产生约20% (较佳为介于15%与25%之间)的重复轴向压缩或扩展，并可同时以最小弯曲半径约13mm(较佳为介于1mm与16mm之间)弯曲，且皆不失效。 The spiral portion is preferably constructed as produce about 20% (preferably between 15% and 25%) repeated axial compression or extension, and while the minimum bend radius of about 13mm (preferably, from 1mm to and between 16mm) is bent, and neither failure.
[0049] 如果螺旋组件18在连接至螺旋组件18的支柱组件16a之间以至少90度加以卷绕，便能够产生较佳的可挠性与轴向压缩；或者是，螺旋组件18系以360度卷绕于连接至螺旋组件18的支柱组件16a之间。 [0049] If the coil assembly 18 is connected to the coil assembly 18 between the strut assembly 16a wound to be at least 90 degrees, it is possible to produce a flexible and preferred axial compression; or a spiral line assembly 18 to 360 of the spiral wound assembly is connected to the strut assembly 18 between 16a.
[0050]图2是本发明一第二实施例的平面图，其说明了与图1所示的支架10类似的支架20 ;其基本的差别在于支柱部分12'的结构以及右旋与左旋的螺旋部分(分别为14R与14L)。 [0050] FIG. 2 is a plan view of a second embodiment of the present invention, illustrating a stent similar to stent 10 shown in FIG. 20; the basic difference is that the strut portion 12 'of the right-handed and Zuo Xuan structure, and a coil portion (14R and 14L, respectively). 每个支柱部分12'包括两个相邻的支柱环26、27，其通过一短链节28加以连接。 Each strut portion 12 'comprises two adjacent ring struts 26, 27, which is to be connected by a short link 28. 支柱组件26a、27a紧密相对的尖峰是由短链节28加以连接，因而各支柱部分12'具有一双重支柱环结构；也可以同时连接多个支柱环而形成一个较大的支柱部分。 Strut assembly 26a, 27a closely opposed spike is to be connected by a short link 28, and thus each of the strut portion 12 'has a double ring structure struts; simultaneously a plurality of struts may be connected to form a larger ring strut portion. 具有双重或多重支柱环之支柱部分的优点在于其提供了比单一支柱环之支柱部分更大的径向刚度，且可稳定支柱部分使其较不会受到轴向力量的影响。 Leg portions has the advantage of dual or multiple rings struts provide more than a single strut of the strut ring portion in its radial stiffness, and may be more stable strut portion into the axial forces will not be affected.
[0051] 在右旋螺旋部分14R中，组件18是沿支架10的表面以顺时钟方向前进，而在左旋螺旋部分14L中则以逆时钟方向前进。 [0051] In the right-handed screw portion 14R, the assembly 18 along the surface of the stent 10 proceeds in a clockwise direction and counterclockwise direction places advancing portion 14L of the Zuo Xuan screw. 螺旋组件18基本上是浮动的，且可沿着在任一端的两个支柱环部分之间的支架轴产生相对较大的移位；在此一实施例中，可知在每个螺旋部分14R、14L的支架直径与在任一侧上支柱部分12的支架直径相同。 Coil assembly 18 is substantially floating, and may be a relatively large displacement along the support shaft between the two struts at either end of the ring portion; In this embodiment, it is found in each of the helical portion 14R, 14L the stent diameter is the same on either side of the strut portion 12 of the stent diameter. 然而，这并非必要的情况，且其可由下列实施例说明清楚理解。 However, this is not necessary, and it can be clearly understood by the following examples. 使用左旋与右旋螺旋部分的好处是，当支架展开时，这两个部分会以相反方向加以旋转，而保持支架不同轴向位置的相对旋转位置。 The advantage of using the Zuo Xuan handed screw portion, when the stent is deployed, the two parts can be rotated in the opposite direction, while holding the relative rotational position of the different axial positions of the stent.
[0052] 图3显示的是根据本发明另一实施例的支架30，其与图2所显示的支架20类似，除了螺旋部分34包括双向前进的螺旋组件38之外；螺旋组件38沿着不同支柱部分12'上连接位置之间的支架30边缘双向前进(先以逆时钟方向前进，然后以顺时钟方向前进)；螺旋组件38是以至少90度从一第一支柱部分12'卷绕至尖峰35，并从尖峰35以90度卷绕至一第二支柱部分12'，以维持可挠性。 [0052] FIG. 3 is another embodiment of the bracket 30 of the present invention, which is similar to stent 20 shown in FIG. 2, except that the coil assembly comprises a helical portion 34 beyond the forward bidirectional The display 38; a coil assembly 38 along different strut portion 12 'of the edge of the bracket 30 between a forward two-way connecting position (counterclockwise in a first direction, then proceeds in a clockwise direction); coil assembly 38 is at least 90 degrees from a first leg portion 12' is wound to spikes 35 and 90 degrees from the spike 35 is wound to a second strut portion 12 ', in order to maintain flexibility. 图1A与图1B所示的单向螺旋组件18可使相邻的支柱部分相对于彼此而旋转；而双向螺旋组件38则限制了相邻的支柱部分可以沿着支架轴、相对于彼此而旋转的量，但仍可提供轴向与弯曲可挠性。 FIG unidirectional coil assembly shown in FIG. 1B 1A 18 allow adjacent strut rotate relative to each other part; and 2-way screw assembly 38 adjacent to the restricted portion may strut along the stent axis and rotating relative to each other amount, but still provide axial bending flexibility.
[0053] 图4显示的是根据本发明第四实施例的支架的平面图，在此例中，支架40具有如图2所示的支柱部分12'以及螺旋部分14R、14L(图2)与螺旋部分34(图3)。 [0053] FIG. 4 shows a plan view of a stent according to a fourth embodiment of the present invention, in this embodiment, the stent having struts 40 as shown in FIG portion 12 'and a helical portion 14R, 14L (FIG. 2) and the coil portion 34 (FIG. 3). 此种建构方式的优点在于其结合了不同类型的螺旋组件，因而可得到此处所说明特性的组合，其提供了针对一给定应用而进一步使整体支架效能最佳化的机会。 Construction advantage of this embodiment is that it combines different types of helical components, and thus obtain the combination of properties described herein, which is provided for a given application further optimize the performance of the overall stent opportunity.
[0054] 图5是一截面图，其显示了垂直于本发明第五实施例之支架30'的轴的截面，而图6是同一实施例的侧面示意图。 [0054] FIG. 5 is a cross-sectional view which shows a vertical section of the shaft of the embodiment of the stent 30 'in the fifth embodiment of the present invention, and FIG. 6 is a schematic side view of the same embodiment. 所述支架具有如图3所示的结构，除了其螺旋部分38'的直径比支柱部分12'更大之外；这样的建构方式可增加螺旋部分的径向刚度，但仍达比支柱部分低的程度。 The stent having the structure shown in FIG. 3, in addition to the helix 'in diameter than the strut portion 12' larger portion 38; increase the radial stiffness of the helical portions manner such construction, but still lower than that of the pillar portion Degree.
[0055] 当支架的所有部分都具有相同直径，在支柱扩展时，螺旋部分对血管的外向力可能不会跟支柱部分一样多；图6所示的几何方式会倾向于迫使螺旋部分扩展的比支柱部分多，以增加螺旋部分的外向力，其均衡了径向刚度。 [0055] When all parts have the same diameter of the stent, expansion strut when the coil portion outward force on the vessel may not be as much as with the pillar portion; extension force than the portion of the coil geometry shown in FIG. 6 will tend to multi-part strut, in order to increase the outward force of the coil portion, which balances the radial stiffness.
[0056] 镍钛合金结构具有偏移之刚度，因此当支架处于其扩展状态时，要将结构反向折回折迭状态所需要的力一般会大于继续膨胀受病血管所需的力；在部分的自扩展镍钛合金支架中，会使用球囊来辅助血管的扩展/膨胀。 [0056] Nitinol structure having a stiffness of the offset, so that when the stent is in the expanded state, to reverse folded structure folded state force required generally greater than the force required to continue the expansion vessel Shoubing; partial the self-expanding nitinol stent, the balloon will be used to assist in the expansion vessel / expansion. 此偏移之刚度足以支撑开启的血管，但外向力则可能不足以开启血管(或是可能需要一段更长的时间)。 This offset stiffness sufficient to support the open vessel, but may not be sufficient outward force open the vessel (or a longer period may be required). 因此，使用具有如图5所示几何类型的支架来结合球囊辅助扩展会是一种良好的方案。 Thus, having to be extended in conjunction with balloon stent geometry type shown in FIG. 5 is a good solution.
[0057] 图7A是根据本发明另一实施例的支架40B'的平面图，支架40B'包括支柱构件42，支柱构件42从支架40B'的一端螺旋前进到其另一端；支柱构件42形成了支架40B'的主体。 [0057] FIG. 7A is a stent according to another embodiment of the present invention, 40B 'of the plan view, the bracket 40B' includes a post member 42, strut member 42 from one end of the coil holder 40B proceeds' to the other end thereof; forming a stent strut member 42 body 40B 'of. 在此实施例中，每个支柱组件44a都通过螺旋组件46而连接到支柱构件42下一圈的支柱；在此实施例中，螺旋部分45的螺旋组件46沿支架40B'螺旋前进的量小于一个完整旋转的360度，螺旋组件46前进的方向与支柱构件42沿支架40B'螺旋前进的方向相反。 In this embodiment, each strut assembly 44a are connected to the strut member by the turn of the coil assembly 46 under the struts 42; in this embodiment, the helical 'spiral that spirals amount of component 46 along the support portion 45 is less than 40B a full 360 degrees of rotation, the opposite direction of the helical coil assembly 46 proceeds forward direction of the strut 42 along the support member 40B '.
[0058] 较佳为，螺旋组件46在轴向上彼此相邻，而形成一种弹簧，其可实现较大程度的挠曲度与轴向扩展，而支柱构件42则提供了径向强度，并使支架保持于其扩展情况。 [0058] preferably, a spiral assembly 46 adjacent to each other in the axial direction, and form a spring, which may be implemented with a greater degree of deflection of the axial extension 42 and the strut member provides radial strength, and holding the stent in its expanded conditions.

[0060] 支架40B'与40C'的优势在于可以沿着支架长度更连续分布可挠螺旋组件，且可提供更连续的可挠性。 'And 40C' advantages [0060] wherein the stent 40B may be more continuous distribution of the flexible coil assembly along the length of the stent, and may provide a more continuous flexible.

[0074] 图12A、1213与12C是根据本发明支架200的平面图。 [0074] FIG. 12A, 1213 and 12C is a plan view of stent 200 of the present invention. 图12A显示支架200的扩展状态，其在螺旋状元件18之间距有间隙202。 12A shows an expanded state of the stent 200, a gap 202 which spiral element 18 of pitch. 图1213与12C显示支架200 FIG 12C shows stent 200 and 1213
[0075] 的两种不同压缩状态。 [0075] The two different compressed state. 在图12B中，支架200为压缩状态，因此遍及螺旋状部分14，介于并列螺旋状元件18之间的间隙212便大概相同。 In FIG 12B, the stent 200 in a compressed state, and therefore throughout the helical portion 14, a gap interposed between the juxtaposed 18212 elements will be approximately the same spiral. 介于并列螺旋状元件18之间的间隙212尺寸可以介于O以及大约所述间隙在扩展状态中的尺寸范围之间，举例而言，如在图12A中所示。 Interposed between the helical element 18 juxtaposed between the size of the gap 212 may be between about O and said gap size ranges in the expanded state, for example, as shown in FIG. 12A. 换句话说，当所述间系尺寸为O时，在并列螺旋状元件18之间并无空间，而并列螺旋状元件18便彼此接触。 In other words, when the dimension between the lines is O, there is no space between the helical element 18 in parallel, and parallel to the helical member 18 will contact each other.
[0076] 在图12B中所显示所述支架的所述螺旋状元件已经沿着所述支架缠绕许多次，因此在所述蜷曲状态中，在所述蜷曲状态中的所述支架总长度211是与在图12A终于所述扩展状态中的所述支架总长度201相同，藉此消除缩短情况。 [0076] shown in FIG. 12B in the helical member of the stent along said stent has been wound many times, thus the crimped state, the total length of the stent in the crimped state 211 the same as the overall length of the stent in the expanded state of FIG. 12A in the last 201, thereby eliminating the situation shortened.
[0077] 在图12C中，支架200为压缩状态，因此螺旋状元件18被拉长，而介于并列螺旋状元件18之间的间隙222则遍及螺旋状14的轴向长度而不同。 [0077] In FIG. 12C, the stent 200 in a compressed state, so the helical member 18 is elongated and is interposed between the gap 18 parallel helical element 222 over the axial length of spiral 14 differs. 介于并列螺旋状元件18之间的间隙222尺寸可以介于O以及大约所述间隙202在扩展状态中的尺寸范围之间，举例而言，如在图12A中所示。 Juxtaposed helical member interposed between the size of the gap 222 between O and 18 may be interposed between the gap size range of about 202 in the expanded state, for example, as in FIG. 12A. 换句话说，当所述间系尺寸为O时，在并列螺旋状元件18之间并无空间，而并列螺旋状元件18便彼此接触。 In other words, when the dimension between the lines is O, there is no space between the helical element 18 in parallel, and parallel to the helical member 18 will contact each other. 在图12C中，在所述蜷曲状态中，在所述蜷曲状态中的所述支架总长度221是与在图12A中于所述扩展状态中的所述支架总长度201相同， In FIG. 12C, in the crimped state, the total length of the stent in the crimped state 221 is the same as the overall length of the stent in FIG. 12A in the expanded state 201,
[0078] 可以提供另一种方法以蜷曲所述支架，因此在所述蜷曲状态中的螺旋状部分长度比在所述扩展状态中的短。 [0078] Another method may be provided to the crimped stent, thus partially helical length of the crimped state than in the expanded state is shorter. 举例而言，如果图12A的所述支架，除了在并列螺旋状元件之间并不存在间隙以外，是利用图12B中所显示的相同方式所蜷曲，所述支架于所述蜷曲状态中所具有的长度211，将比在所述扩展状态中的长度201短。 For example, if the stent of FIG. 12A, except there is no gap between the helical elements in parallel, using the same manner as shown in FIG. 12B being crimped, the stent in the crimped state has length 211 than the extended length of the state 201 is short. 在一实施例中，一种蜷曲的方法提供一种支架，其在蜷曲与扩展状态中的总长度相同，而在所述蜷曲状态中，于螺旋状元件支件不存在间隙。 In one embodiment, a method of providing a stent crimped, curled in the same total length and the expanded state, while in the crimped state, in the helical member support element there are no gaps.
[0079] 如同以上所描述，所述支架的一较佳实施例能够准许大约20%的重复轴向压缩及扩展，并同时准许最小弯曲半径大约为13毫米(mm)支架。 [0079] As described above, the preferred embodiment of a stent can be approximately 20% of the repeat permit axial compression and expansion, and while permitting a minimum bend radius of about 13 millimeters (mm) bracket. 一种建构具有具体弹性目标的本发明支架的方法是改变介于在所述螺旋状部分中该间隙空间总和与所述总长度之间的比例。 Construction of one kind of specific scaffolds of the invention has an elastic target is to change the ratio between the clearance space between the sum of the total length of the helical portion. 利用增加所述比例的方式，所述支架的弹性将增加。 The advantage of the increased proportional manner, will increase the elasticity of the stent. 所述比例大概是所述支架所能遵循的得最大轴向压缩。 The ratio is about the stent can be followed to obtain the maximum axial compression. 可以体会的是，为了安全性的考虑，所述最大轴向压缩将受到其它像是在所述螺旋状部分中应变等因子的限制。 We can understand that, for safety considerations, the maximum axial compression will be limited by other factors such as the strain in the helical portion.
[0080]图13是根据本发明支架300的一替代实施例的平面图。 [0080] FIG. 13 is a plan view of an alternative embodiment of a stent 300 in accordance with embodiments of the present invention. 支架300其以上描述的其它实施例一样，除了其包含具有不同配置与不同轴向长度的支柱部分，以及不同配置与不同轴向长度的螺旋状部分。 Like bracket 300 to other embodiments thereof described above, except that it comprises a strut portion having a different configuration and different axial lengths, and different configurations of a spiral portion with a different axial length. 位在所述支架300最外侧部分的支柱部分302包含长支柱组件301。 Bit portion of the outermost portion 302 of the stent 300 comprises strut length strut assembly 301. 长支柱组件301具有长度311。 Long strut assembly 301 has a length 311. 长支柱组件301的长度311大于位在所述支架300内侧部分的支柱部分304的长度312。 Long strut assembly is greater than the length of pillars 311,301 bits 300 in the inner portion of the holder portion 304 of the length 312. 在所述支架的末端上提供长支柱组件301可以有利地提供较佳的固定，并提供与邻近支架重迭的区域，但并不妨碍所述螺旋状部分的弹性。 Long strut assembly provided on the end of the bracket 301 may advantageously provide better fixation, and to provide adjacent regions overlap the stent, but does not prevent the elastic helical portion. 在某些脉管系统中，尤其是大腿膝后窝动脉，所述害病动脉的长度可能非常的长，常常大于10厘米。 In certain vasculature, especially the large arteries Tuixi nest, the length of the diseased artery may be very long, and often more than 10 cm. 可能需要多数支架来治疗这些害病动脉的长片段。 Most stent may be needed to treat these diseased artery long fragment. 此情况中的一般步骤是使邻近支架重迭，因此覆盖被治疗的脉管。 The general procedure in this case is to overlap adjacent the bracket, thus covering the vessel being treated. 当某些传统的支架以此方法重迭时，所述机制将妨碍其弹性，而此人为硬挺方式可能造成许多问题，包含支架断裂。 When some conventional stents overlap this way, the mechanism would prevent its elasticity, and stiffness of this embodiment may artificially cause many problems, comprising a stent fracture. 本发明一项优点是允许弯曲并具有轴向弹性的组件(螺旋状部分)是与提供径向结构的组件(支柱部分)不同，因此在邻近支架上的支柱部分便可以重迭，且不妨碍所述支柱部分的移动与所述支架的完整弹性。 An advantage of the present invention is to allow bending and axial elastic component having a (helical part) is provided with a component (pillar portion) different from the radial structure, so leg portions on adjacent stent can overlap, without prejudice full elastic movement of the bracket portion of the strut.
[0081] 邻近于所述支柱部分302的螺旋状部分303包括螺旋状元件18，其连结至支柱部分302的每一个支柱组件301。 [0081] adjacent to the helical portion 302 of the strut portion 303 includes a helical member 18, each of which is coupled to a pillar portion 302 of the strut assembly 301. 螺旋状部分303可以提供一高百分比的表面面积，以使药剂或其它制药媒介的输送最佳化。 Helical portion 303 may provide a high percentage of the surface area, so that the carrier, or other pharmaceutical agents to optimize media. 支柱部分304则利用螺旋状元件18，于所述支柱部分304侧边320处的每一支柱组件16a处，连结至螺旋状部分303，并在所述支柱部分304侧边321处的每另一支柱组件16a处，连结至螺旋状部分309。 Pillar portion 304 using helical elements 18, 16a at each part of the strut assembly 304 in the side strut 320, portion 303 connecting to a spiral, and each of the other sides of the leg portions 304 of 321 strut assembly 16a at the connecting portion 309 to the spiral. 螺旋状部分309相较于螺旋状部分303而言，提供一较低百分比的表面面积及较大的弹性。 Helical portion 309 as compared to the helical part 303, it provides a lower percentage of the surface area and greater flexibility. 此配置形式可以提供从具有一高百分比表面面积的较硬挺螺旋状部分，至一较弹性螺旋状部分的转换。 This configuration may be provided in the form of transition from stiffer helical portion having a high percentage of the surface area, compared to an elastic helical portion.
[0082] 螺旋状部分309所具有所述间隙长度323总和对于螺旋状部分309的长度324比例，较高于所述间隙长度325总和对于螺旋状部分303的长度326比例，因此螺旋状部分309 一般来说将具有更大的弹性。 [0082] The helical section 309 has a length of the gap 323 to the sum of the length of the helical part 309 324 ratio, the higher the gap length to 325 to 326 ratio of the sum of the length of the spiral portion 303, thus generally spiral portion 309 it will have more flexibility.
[0083] 支柱部分306具有具有支柱组件305的向为支柱部分302或304之半，因此一般来说与支柱部分302或支柱部分304相比之下具有更多的开放区域。 [0083] 306 having a post portion of the strut having a strut assembly 304 of the portion 302 or 305 of the half, thus generally strut or strut portion 302 compared to portions 304 have more open area. 与所述支架其它部分相较，包含具有较大开放区域部分的支架，其优点为所述支架的较大开放区域可以被放置在一分叉动脉上，并且不妨碍血液流动。 Compared with other portions of the stent, the stent comprising a larger portion of the open area, which open area of ​​the large advantage that the stent may be placed in a bifurcated artery and does not interfere with blood flow. 反之，具有一较高支柱组件密度的支柱部分则可能妨碍血液流动。 Conversely, a strut portion having a higher density strut assembly may interfere with blood flow.
