    • An implant (1) for closing passages in organs is proposed, comprising a primary coil (2) consisting of a resilient material, where the implant (1), in an operational state, forms a secondary coil (3) of greater diameter than that of the primary coil (2), where the implant (1) can be converted by a guide element (5) from the shape of the secondary coil (3) into a transporting state in which the implant (1) adopts an elongate shape, and the implant (1) once again assumes the operational state by removal of the guide element (5). In order to improve the success of treatment, it is proposed, for achieving a better securing of the implant (1) in a larger passage of an organ, that the primary coil (2) has areas of different transverse spring rate along its longitudinal extent. A set is furthermore proposed with an implant (1) according to the invention, and a device for applying such an implant (1) with a guide element (5).
    • 提出了一种用于关闭器官中的通道的植入物(1),其包括由弹性材料组成的初级线圈(2),其中所述植入物(1)在操作状态下形成直径大于该直径的次级线圈(3) 的原始线圈(2),其中通过引导元件(5)将植入物(1)从次级线圈(3)的形状转换成植入物(1)采用细长形状的输送状态, 并且通过移除引导元件(5),植入物(1)再次呈现操作状态。 为了改善治疗的成功,提出为了实现植入物(1)更好地固定在器官的较大通道中,初级线圈(2)沿其纵向范围具有不同的横向弹簧刚度的区域 。 此外,还提出了根据本发明的植入物(1)和用于将这种植入物(1)与引导元件(5)一起施加的装置。

    • A left atrial appendage occlusion device including an occluder disk configured to substantially prevent blood from at least one of entering and exiting the left atrial appendage, a middle portion including a coiled element and a first anchoring element. The coiled element connects to the occluder disk, has a substantially constant cross section and allows for variable length, variable orientation, and/or varied angles. The first anchoring element connects to the coiled element and includes scalloped edges that are configured to anchor the occlusion device to inner walls of the left atrial appendage and reduce the risk of one of penetration and perforation of walls of the left atrial appendage. The left atrial appendage occlusion device may also include a self-centering element that connects to the occluder disk and middle portion and is configured to center the occlusion device within the orifice of the left atrial appendage.
    • 一种左心耳闭塞装置,包括封堵器盘,其构造成基本上防止来自进入和离开左心耳中的至少一个的血液,包括盘绕元件和第一锚定元件的中间部分。 线圈元件连接到封堵器盘,具有基本上恒定的横截面并且允许可变长度,可变取向和/或变化的角度。 第一锚固元件连接到线圈元件并且包括扇形边缘,其被构造成将闭塞装置锚定到左心耳的内壁并且降低左心耳壁的穿透和穿孔之一的风险。 左心耳闭塞装置还可以包括连接到封堵器盘和中间部分的自定心元件,并且构造成使闭塞装置在左心耳的孔内居中。
