本发明涉及管形组织的支承装置,具体涉及插入分支管的分叉的管形组织支承装置以及制造这种支承装置的方法。
管形组织的支承装置是这种技术中众所周知的。这些支承装置通常用圆筒形的金属网制作,该网在内部加压时可以膨胀。或者,这些支承装置可以用绕成圆筒形的金属丝或形成圆筒形状的片材制作。
管形组织的支承装置是一种通常植入人体内包括血管系统的管道中的一种装置,用于增强血管萎缩的、局部堵塞的、衰弱的或反常扩张的部分。这种支承组织还成功地植入其它的区域例如尿道或胆管,以增强这种体内管道。
美国专利NO.4994071(Mac Gregor)公开一种可膨胀的分叉的管形组织的支承装置,该支承装置具有用相互连接的柔性金属丝作的圆筒形主网格。另外两个直径小于主网格的圆筒网格具有类似结构。主网格包括使主网格连接于一个另外网格的柔性金属丝。第二柔性金属丝使主网格连接于另一个另外网格。这些柔顺金属丝构成沿主网格长度和各个另外网格延伸的脊骨。这种分叉支承装置的缺点是构成脊骨的柔性金属丝与各个网格的环形结构的相互连接很复杂。

在图1所示实施例中,分叉的支承装置包括第一腿10、第二腿15及主干10。图2示出用来形成第一腿10的第一片25、用来形成第二腿15的第二片30以及用来形成主干20的第三片35。第一片25和第2片30基本上是平的,具有预定长度和宽度。对于很多应用,第一片25和第二片30具有基本上相同的尺寸,以形成尺寸基本相同的腿10和15,然而腿10、15以及制作它们的片25、30可以根据特定的应用要求而具有不同的尺寸。本发明的支承装置这样定尺寸,使得在组装时的尺寸便是其最后尺寸,然而在优选实施例中,支承装置是可膨胀的,其尺寸被定为适合于在膨胀时形成其最后尺寸。支承装置的片70和75上作成或蚀刻成一定的图案,根据特定的应用要求,孔眼形成各种图案,以便达到要求的如前所述的可膨胀特性。第三片35的尺寸定为当其被卷曲成管子的使其内横截面可以接纳第一腿10和第二腿15的横截面外直径。第一片25具有第一边缘26、第二边缘27、第三边缘28和第四边缘29。第二片30具有第一边缘31、第二边缘32、第三边缘33和第四边缘34。第三片35具有第一边缘36、第二边缘37、第三边缘38和第四边缘39。在切下金属片形成片25、30和35之后,使其形变和卷曲,使两个相对的边缘相接,形成一个圆筒。在图2和3所示的实施例中,边缘27通过焊接线14与边缘29连接形成第一腿10。边缘32通过焊接线19连接边缘34,形成第二腿。边缘37通过焊接线29连接于边缘39,形成主干20。这些边缘可以以技术人员周知的适合于此目的的各种各样方式连接起来,例如拧紧、压边、低温焊,然而在优选实施例中采用熔焊。在一个特别优选的实施例中采用点焊。如图3所示,第一腿10具有近端11、远端12,并形成纵向孔13。第二腿15具有近端16、远端17,并形成纵向孔18。主干20具有近端26、远端27,并形成纵向孔28。图4示出正要组装前的第一腿10、第二腿15和主干20。为形成分叉的支承装置5,将第一腿10的近端11和第二腿15的近端16结合起来,形成主干20的远端27,使得纵向孔13、18和28彼此连通。图5是已装配装置的端视图,图6是侧视图。
图11示出本发明分叉支承装置的第二实施例。支承装置50具有连接于主干部分65的第一腿55和第二腿60。分叉的支承装置50用如图7所示的第一腿70和第二腿75形成。支承装置的片70和75上可以作成或蚀刻出一定图案,根据特定的应用要求其上孔眼形成各种图案,以得到要求的如前所述的可膨胀特征。片70和75基本上是平的,具有预定的长度和宽度。第一片70具有第一、第二、第三和第四边缘71、72、73和74。第二片75具有第一、第二、第三和第四边缘76、77、78、79。为形成支承装置的腿,将边缘72的一部分卷向边缘74的一部分,将边缘77的一部分卷向边缘79的一部分。在片70和75上选择分界点80、81、82和83,如图图8所示。选择这些分界点80、81、82和84使其满足特定的应用要求,并可以根据对腿55和60所需要的长度以及对主干65所需要的长度进行调整。分界点80和81距边缘73和71是等长的,而分界点82和83距边缘76和78是等距的,这样便形成一个腿55和60的长度大体等于主干部分65长度的支承装置。如果选择分界点,使其与边缘71和76相比更靠近边缘73和78,则主干的长度大于各个腿的长度。如果选择分界点,使其与边缘73和78相比更靠近边缘71和76,则各个腿60和65的长度将大于主干65的长度,然而在优选实施例中,选择分界点81、82、83和84,使得近边缘72″、74″、77″和79″的长度约为边缘72、74、77和79的长度的三分之一。如图8所示,分界点80约在边缘72的中点将该边缘分成远边缘72′和近边缘72″。分界点81约在边缘74的中点将该边缘分为远边缘74′和近边缘74″。分界点82约在边缘77的中点将该边缘分成远边缘77′和近边缘77″,而边界点83约在边缘79的中点将该边缘分成远边缘79′和近边缘79″。
为形成支承装置,将边缘72′通过焊接线90连接于边缘74′,形成第一部件95,该部件具有第一腿部分55和主干的第一半65′,如图9所示,将边缘77′通过焊接线91连接于边缘79′,形成第二部件100,该部件具有第二腿部分60和主干的第二半65″。如前所述,可以采用技术人员熟知的各种各样方式连接这些边缘。图10示出正要组装之前的图9所示的第一部件95和第二部件100。为形成图11和12所示的分叉支承装置50,将边缘72″经焊接线92连接于边缘79″,将边缘74″经焊接线93连接于边缘77″,使得主干的第一半65′和主干的第二半65″形成主干65。图12是图11所示支承装置的横截端视图。
在图7的实施例中,片70和75是方形的或矩形的。然而片70和75不限于这种结构,如图7B所示。图11B示出用图7B所示的片270和275作的分叉的支承装置。支承装置250具有连接于主干部分265上的第一腿255和第二腿260。分叉的支承装置250用图7B所示的第一片270和第二片275制作。支承装置的片270和275具有确定的尺寸并如前所述地被蚀刻。如图7B所示,第一片270具第一边缘271、第二边缘272、第三边缘273、第四边缘274、第五边缘275和第六边缘276、第七边缘146以及第八边缘147。第二片275具有第一边缘277、第二边缘278、第三边缘279、第四边缘280、第五边缘281、第六边缘282、第七边缘148和第八边缘149。如图9B所示,边缘274经焊接线290连接于边缘276,形成第一部件295,该部件具有第一腿部分255和主干的第一半265′。边缘280经焊接线291连接于边缘282,形成第二部件300,该部件具有第二腿部分260和主干的第二半265″。如前所述,这些边缘可以采用技术人员熟知的各种各样方式连接。图10B示出组装前正对直的图9B所示的第一部件295和第二部件300。为形成图11B和12B所示的分叉支承装置250,将边缘272经焊接线292连接于边缘149,并将边缘278经焊接线293连接于边缘147,使得主干的第一半265′和主干的第二半265″形成主干265。图12B是图11B所示支承装置的横截端视图。图12C示出替代的构形,该构形可以用来替代图7和7B所示的构形。
本发明的第三实施例包括两部分,该两部分两步顺序配置和组装在病人体内,以形成分叉的支承装置。图13示出主干与第一腿部分110,这一部分具有;纵向孔131;构成主干部分125的近端115;构成第一腿部分130的远端120。第二腿部分140具有纵向孔32、近端145和远端150。主干和第一腿部分110以及第二腿部分140具有一定尺寸并作成或蚀刻出如前所述的一定图案。分支孔135配置在主干和第一腿部分110的近端115和远端120之间。分支孔135的尺寸被定为可以接收第二腿部分140,并在该第二腿部分在分支孔135中膨胀时可以啮合和固定该第二腿部分140。第二腿部分140的尺寸被定为在膨胀时可以被啮合和固定在分支孔135内。图14~21示出如何将分叉的支承装置装配在分叉的腔中。如图14~21所示,待治疗的区域是分叉的腔,该发叉的腔具有第一腔或主腔190和第二腔或分支腔195。如图14所示,将第一引导金属丝155引入主腔190,将第二引导金属丝156引入分支腔195。如图15所示,将气囊式可膨胀的主干和第一腿部分110配置在第一气囊导管170的头部,使得气囊175位于纵向孔131内。然后将第二气囊导管171插入主干和第一腿部分110的纵向孔131并向前移动,使得气囊176位于孔135内。第一导管170装在第一引导金属丝155上,而第二导液管171装在第二引导金属丝上。如图16所示,将未膨胀的主干和第一腿部分110导入到待治疗的区域,使得第一腿部分110位于主腔190内,并使分支孔135与分支腔195连通。引导金属丝156有利于使分支孔135沿分支腔195定位。常规导管和气囊的尺寸是不成比例的,为清楚起见,技术人员周知的细节已省去。使气囊175充气,造成主干和第一腿部分110膨胀,如图17所示,从而将其固定在要求的位置。膨胀后,主干和第一腿部分110的外壁将接触主腔190的内壁,然而为清楚起见,故意留出一个间隙。使第一导管上的气囊170保持在充气状态,然后使第二导管171上的气囊176充气,扩大分支孔135,如图18所示。在扩大分支孔135时,支承装置的构成分支孔135的那部分被向外撑,形成分支紧固唇部180。
使气囊175和176均充气,退回第二导管171,并将第二引导金属丝156留在分支腔195的位置上。然后将第二腿部分140加在第二导液管171,使得气囊176配置在纵向孔132内,然后将第二导液管171加在第二引导金属丝156上。随后引导和导入第二腿部分140进入主干和第一腿部分110的纵向孔131,并前移,穿过分支孔135,使得第二腿部140的远端150伸入到分支腔195内,使近端145与纵向孔131连通,如图19所示。使第二导管171上的气囊176局部充气,然后使第一导管170上的气囊局部充气,充到其压力基本上等于气囊176中的压力。随后使两个气囊175和176同时充气到基本上相等的压力。如图20所示,在第二导管171上的气囊176的充气使第二腿部件140膨胀,使得其外壁啮合和固定在包围孔135的区域上。第一导液管170上的气囊175的充气可以防止在使气囊176充气时主干和第一腿部分110的塌缩。膨胀后,第二腿140的外壁将接触腔195的内壁,然而为清楚起见,在图上特意留了一个间隙。使气囊175和176均充气,然后退回导液管170和171以及引导金属丝155和156,因而装好的分叉支承装置便留在原处,如图21所示。
图22~31示出制造本发明的分叉支承装置的特别优选的方法。图22示出用来形成第一可膨胀管形件301的片300。该片300具有纵轴线302、圆周轴线303、近端304、远端305、第一侧边306、第二侧边307、第三侧边308、第四侧边309、第五侧边310和第六侧边311。该片300上可以具有各种各样的图案,然而在优选实施例中,该片300具有许多可膨胀的网格312,该网格在第一管形件301膨胀之前基本上是柔性的,但在第一管形件301膨胀之后则变成基本上刚性的。在特别优选的实施例中,该片300的柔性网格312基本上是均匀的,如图22所示。
该片的第一侧边306具有近部分313,该近部分具有近端314和远端315。第一侧边306还具有远端部分316,该远端部分具有近端317和远端318。
该片300的第二侧边307具有近端319和远端320,并位于该片300的近端304和该片300的远端305之间。
该片300的第三侧边308具有近端321和远端322,并位于第二侧边307的远端320和该片300的远端305之间。
该片300的第四侧边位于第一侧边306近部分313的近端314和第二侧边307的近端319之间。
该片300的第五侧边位于第一侧边306远部分316的远端318和第三侧边308的远端322之间,并具其长度L1小于第四侧边309的长度L2。在优选实施例中,第五侧边310的长度L1和第四侧边309的长度L2之比约为5∶7,即第五侧边310的长度L1约为第四侧边309的长度L2的约70%。在特别优选的实施例中,片300被蚀刻成具有许多如前所述的大体均匀的网格312,并且沿第五侧边310圆周轴线303配置的网格的数目与沿第四侧边309的圆周轴线303配置的网格的数目之比约为5∶7。
第六侧边311位于第二侧边307和第三侧边308之间。在特别优选的实施例中,第一侧边306、第二侧边307和第三侧边308基本上彼此平行,而第四侧边309、第五侧边310和第六侧边311基本上彼此平行,并且第一侧边306、第二侧边307和第三侧边基本上垂直于第四侧边309、第五侧边310和第六侧边311。
为制作第一可膨胀管形件301,片300的第二侧边307通过连接装置连接于片300第一侧边306的近部分313,而片300的第三侧边308通过连接装置连接于片300第一侧边306的远部分316上,从而形成第一可膨胀管形件301,该管形件具有形成纵向轴线324的纵向孔323,如图23所示。利用技术人员熟知的适合于此目的各种各样的方法可以执行连接步骤,然而,在优选实施例中,可利用拧紧、卷边、低温焊、熔焊或点焊执行连接步骤。在图23所示的实施例中已利用点焊325。在如上所述地连接侧边以后,第四侧边309形成管形件的近孔或支承装置近孔326,该孔与纵向孔323连通,第五侧边310形成管形件远孔或支承装置远孔327,该孔与纵向孔323连通,如图23和26所示。第六侧边311、第三侧边308的近端321和第一侧边306远部分316的近端317形成侧向分支孔328(如图23~26所示),该分支孔的尺寸被定为适合于接收和固定第二可膨胀管形件329(如图26~27所示)。分支孔328的直径D1大于未膨胀支承装置的直径D2,即分支孔328在管形件301膨胀之前和之后均大于第一管形件301的近孔和远孔326和327。
然后将第一可膨胀管形件301送入具有第一腔和第二腔的分叉管内,使得第一可膨胀管形件配置在第一腔内,并使分支孔与第二腔连通。在优选实施例中,如前所述,输送是通过气囊导管进行的。在定位第一可膨胀管形件之后,使其膨胀,膨胀到足以使第一可膨胀管形件固定在第一腔中。
然后制备第二可膨胀管形件329,该管形件具有近端330、远端331和贯穿的纵向孔332。第二可膨胀管形件329(如图25、26和27)上可以形成图案,其形成可与片300的形式相同,如前所述。在优选实施例中,用来制造第一可膨胀管形件301的片300的网格312和第二可膨胀管形件329的网格312′基本上是均匀的。
将第二可膨胀管形件329引入到第一管形件301的纵向孔323,如图25所示,并向前移动越过分支孔328,如图26所示,从而将第二可膨胀管形件329的远端331配置在第二腔内并使第二可膨胀管形件329的近端330配置在第一管形件301的纵向孔323内。然后使第二可膨胀管形件329膨胀,膨胀到足以将第二可膨胀管形件329固定在第二腔内和第一管形件301的分支孔328内,如图27所示。
这种支承装置提供较大的分支孔,这有助于将第二管形件引入到上述分支腔或第二腔,这也属于此实施例提供的优点。另外,这种支承装置特别适合于进行连续分叉的支承,也特别适合于在堵塞之前沿侧向支管进行支承。
图28~31示出图23~27所示的替代实施例和制作第一管形件的替代方法。在此实施例中,第一管形件400(如图29所示)包括近部件401和远部件404,前者具有近端402和远端403,后者具有近端405和远端,如图28所示。近部件401具有纵向孔415,并从具有第一横截面直径D1的第一管407上切下来。远部分404具有纵向孔416,并从具有第二横截面直径D2的第二管408上切下来。D2小于D1。在从管407和408上切下近部件401和远部件404之前可以在管401和404上蚀刻或作出如前所述的图案。或者在近部件401和远部件404从管407和408上切下之后再在该近部件401和远部件上蚀刻或作成一定图案。为制作第一管形件400,将近部件401近端403的一部分用连接装置417固定在远部件404近端部405的一部分上,形成第一管形件400,该管形件具有近端409、远端410和贯穿的纵向孔411,如图29所示。如前所述,可以利用各种连接装置417连接部件401和404,然而在优选实施例中,应用的连接装置是熔焊。在特别优选的实施例中采用点焊。因为D2小于D1,所以近部分401的远端403的未连接部分和远部分404近端405的未连接部分形成如图29和30(此图是图29的端视图)所示的分支孔412。在某些应用中,为了增加第一管形件400的强度,在近部件401的远端403和远部件404的近端405未连接之前便使它们的大部分相互接触。在将远端部403连接于近端部405之前,采用例如使近部件401远端403较大表面积和远部件404、近端405的较大表面积形变、对齐和接触的方法便可以实现这一点。图30A是此实施例的端视图,与图30所示的实施例相比较,该图示出远端403和近端405有较大表面积相互连接。图30A还示出,在此实施例中,分支孔412′大于图30的分支孔412。然后将第二管形件413引入分支孔412或412′,随后使其如上所述地膨胀和固定,使得第二管形件413的一部分与纵向孔连通,形成分叉的支承装置414(示于图31)。
