Description

血管壁修复系统
技术领域
本发明涉及血管壁的修复领域,具体地,涉及一种血管壁的修复系统。
背景技术
现今,心脑血管疾病呈多发态势。其中由于本身病变以及在介入治疗中的误伤,血管壁会出现损伤。对于这种损伤可以采用覆膜支架进行修补,其中的覆膜支架技术涉及支架本身的结构设计,也涉及覆膜支架的植入系统设计,结构复杂、操作繁琐并且成本较高。
发明内容
本发明的目的是提供一种血管壁修复系统,该血管壁修复系统结构简单,操作方便。
为了实现上述目的,本发明提供一种血管壁修复系统,该系统包括修复件,可解脱地承载该修复件的输送装置,所述修复件面向所述血管壁的第一侧具有第一粘贴层,其中所述输送装置在将所述修复件输送到待修补位置后,所述输送装置能够将所述修复件抵压到所述血管壁上以使得所述修复件通过所述第一粘贴层粘贴到所述血管壁上。
优选地,所述输送装置为球囊。
优选地,所述修复件与所述第一侧相反的第二次具有第二粘贴层,所述修复件通过所述第二粘贴层粘贴在所述输送装置上,并且所述第二粘贴层的粘贴力小于所述第一粘贴层的粘贴力。
优选地,修复件由聚偏氟乙烯制成。
优选地,第一粘贴层和/或第二粘贴层包含生物胶材料。
优选地,第一粘贴层包含光固化材料。
优选地,血管壁修复系统还包括光源,输送装置为透光球囊,光源设置在透光球囊内。
优选地,第一粘贴层上覆盖有可解脱的离型膜。
优选地,血管壁修复系统还包括连接在离型膜上的控制导丝,以通过该控制导丝能够将该离型膜从第一粘贴层上解脱。
通过上述技术方案,本发明创新地在血管壁修复中采用直接将修复件粘贴到血管壁上的方案,系统结构简单、操作方便并且成本较低。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说明。
附图说明

图1是本发明优选实施方式提供的血管壁修复系统的结构示意图;。
图2是本发明优选实施方式提供的修补件的剖视结构示意图。
附图标记说明
1修复件2输送装置
3第一粘贴层4第二粘贴层
5离型膜6控制导丝
具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是,此处所描述的具体实施方式仅用于说明和解释本发明,并不用于限制本发明。
在本发明中,在未作相反说明的情况下,使用的方位词如“内、外”是指相应部件轮廓的内和外。“远、近”是以进行血管壁修复时的人体介入点为基础定义的,即远离介入点的方向为远,接近介入点的方向为近。
如图1和图2所示,本发明实施方式提供一种血管壁修复系统,该系统包括修复件1,可解脱地承载该修复件1的输送装置2,修复件1面向血管壁的第一侧具有第一粘贴层3,其中输送装置2在将修复件1输送到待修补位置后,输送装置2能够将修复件1抵压到血管壁上以使得修复件1通过第一粘贴层3粘贴到血管壁上。因此,本发明创新地在血管壁修复中采用直接将修复件粘贴到血管壁上的方案,相比传统的覆膜支架修补方式,系统结构简单、操作方便并且成本较低。
在本实施方式中,为了方便完成对修复件1的承载、运输和抵压,优选地,输送装置2为球囊。当球囊携带修复件1移动到待修复的血管壁时,可以通过球囊的扩张而完成将修复件1抵压的血管壁上的工作,这样,利用第一粘贴层3的粘性,实现修复件1粘贴到血管壁上,从而完成血管壁的修复。球囊装置在介入治疗领域中为公知器械,在此对齐在血管中的移动、扩张、收缩等操作不做过多赘述。
另外,为了实现修复件1可解脱地承载在输送装置2上,优选地,如图2所示,修复件1与第一侧相反的第二次具有第二粘贴层4,修复件1通过第二粘贴层4粘贴在输送装置2上,并且第二粘贴层4的粘贴力小于第一粘贴层3的粘贴力。因此,当修复件1通过第一粘贴层3粘贴到血管壁上时,输送装置2可以与修复件2解脱。
此外,在其他实施方式中,修复件1和输送装置2的可解脱承载方式有还有多种,例如滑动连接结构,具体地,可以在输送装置2上设置有容纳槽,该容纳槽在输送装置2的运动方向上的至少一端设置有可供修复件1滑出的开口,当修复件1粘贴到血管壁上时,只需向远或向进侧移动输送装置2,即可实现修复件1从容纳槽中滑出。该容纳槽可以为具有滑动连接功能的T型槽或燕尾槽结构。
在本实施方式中,修复件1的本身材质可以采用现有技术中覆膜支架的覆膜材料,例如聚偏氟乙烯制成,以起到修复作用并且对不会对人体造成伤害。另外上述中的第一粘贴层3和第二粘贴层4中包含的具有粘贴性质的材料可以为各种对人体无害的胶质,例如生物胶。
另外,在某些治疗中需要修复件1能够克服血管的回弹,针对这一问题,本实施方式提供的修复件能够在常规状态具有柔性特性,而在需要时,则能够固化。这种材料在本发明中优选为光固化材料,即可以在修复件1或第一粘贴层3中包含光固化材料,例如UV树脂。这样,只需在需要时使用例如紫外LED光源照射即可使得修复件1固化在血管壁上,从而克服血管的回弹问题。
相应地,为了实现对修复件1进行照射,血管壁修复系统还包括光源,通过例如能够产生紫外光的LED,另外为了便于操作,输送装置2可以设计为透光球囊,这样,光源可以设置在透光球囊内,从而既能够实现修复件的输送,还能够实现修复件的可选择性的固化。其中光源的控制可采用有线和无线的方式,其中涉及的线路可以布置在球囊的供气、供液管路。本发明实施方式中的球囊可以为二氧化碳充气球囊。
此外,为了避免在未粘贴到血管壁之前,第一粘贴层3粘到其他物质,优选地,该第一粘贴层3上覆盖有可解脱的离型膜5。这样只有在需要进行粘贴作用是,才将离型膜5去除,从而充分保证修复件1和血管壁的粘贴效果。具体地,血管壁修复系统还包括连接在离型膜5上的控制导丝6,以能够通过对该控制导丝6的控制,将该离型膜6从第一粘贴层3上解脱。具体地,控制导丝6的远端连接与离型膜,近端延伸到人体外即可,这样通过操作体外端,例如拖曳的操作即可实现将离型膜脱离第一粘贴层3。
以上结合附图详细描述了本发明的优选实施方式,但是,本发明并不限于上述实施方式中的具体细节,在本发明的技术构思范围内,可以对本发明的技术方案进行多种简单变型,这些简单变型均属于本发明的保护范围。
另外需要说明的是,在上述具体实施方式中所描述的各个具体技术特征,在不矛盾的情况下,可以通过任何合适的方式进行组合,为了避免不必要的重复,本发明对各种可能的组合方式不再另行说明。
此外,本发明的各种不同的实施方式之间也可以进行任意组合,只要其不违背本发明的思想,其同样应当视为本发明所公开的内容。
