    摘要： A method and device to elevate retainers on a suture thread to a desired angle such that the retainers can retain the desired elevation. The retainers can be elevated using an apparatus having at least one roller and at least one bending bar, wherein the bending bar contacts the retainers adjacent to the at least one roller to apply a force to the retainers. The retainers can also be elevated using a tube-shaped apparatus which allows the retainers on a suture thread to be bent by the inner surface of the tube-shaped apparatus. In various embodiments of the invention, a suture can be made up of an inner core and a coating that upon a stimuli increases the protrusion of the retainers away from the suture core thereby ensuring that the suture is held securely in place, preventing wound separation and dehiscence. In an embodiment of the invention, the application of the coating to the outer face of the retainer and attractive forces between the coating at different points results in the distension of the retainers away from the suture core. In an alternative embodiment of the invention, the coating inserts into the cut associated with the retainer and repulsive or expansive forces result in a pushing out of the cut and thereby the distending of the retainers away from the suture core.

    摘要翻译： 一种将缝合线上的保持器提升到所需角度的方法和装置，使得保持器可以保持期望的高度。 保持器可以使用具有至少一个辊和至少一个弯曲杆的装置来提升，其中弯曲杆接触与至少一个辊相邻的保持器，以向保持器施加力。 保持器也可以使用允许缝合线上的保持器被管状装置的内表面弯曲的管状装置来升高。 在本发明的各种实施例中，缝合线可以由内芯和涂层组成，其在刺激时增加保持器远离缝合线芯的突起，从而确保缝合线牢固地保持就位，防止缠绕分离， 裂开。 在本发明的一个实施例中，将涂层施加到保持器的外表面和在不同点处的涂层之间的吸引力导致保持器远离缝合线芯的扩张。 在本发明的替代实施例中，与保持器相关联的切口中的涂层插入物和排斥力或膨胀力导致切口的推出，从而保持器远离缝合线芯的膨胀。

    摘要： Devices for excluding aneurysms and treating atherosclerotic disease, for intra-aneurysmal occlusion, and devices for preventing distal emboli. The devices are generally pliable and collapsible thin film devices which can be delivered via a microcatheter into the desired location where they are deployed and undergo either a shape memory phase transformation or in situ polymerization to assume the stable configuration of a permanent endoluminal prosthesis. Prior to being caused to assume their final shape, the devices remain soft, collapsible and pliable to ensure atraumatic delivery through the vascular system. Upon reaching the endoluminal defect in the vessel, the device is extruded from the microcatheter. Devices are also provided for retrieving clots.
