Embodiment approach

[0112] figure 2 yes Figure 1A and Figure 1B A side view of the occlusion device 100 shown in a partially deployed configuration after the distal portion 108 and the intermediate portion 106 have exited the delivery catheter 200 . Such as figure 2 As shown, the guide region 122 extends in a first direction A1 through its proximal end 122a and its distal end 122b. In some embodiments, the proximal end 122a and the distal end 122b can refer to corresponding cross-sectional areas of the guide region 122, and the first direction A1 can be defined by a line extending through the center of each cross-sectional area. The proximal portion 104 extends in the second direction A2 with a portion of its length immediately adjacent to the intermediate portion 106 . For example, an intermediate positioning path along the longitudinal direction of the distal-most portion 120 may define a second direction A2.

Abstract

Devices, systems and methods for treating vascular defects are disclosed herein. For example, one aspect of the present technology relates to an occlusion device comprising a proximal portion, a distal portion, and an intermediate portion (1006, 106, 1106, 1206, 706, 806, 906) extending between the proximal portion and the distal portion. . The distal portion may include a guide region and an introducer element extending distally from the guide region. When the occlusion device is in the deployed configuration, the intermediate portion (1006, 106, 1106, 1206, 706, 806, 906) may form a predetermined bend in the occlusion device that divides the leading region relative to the proximal portion. Angular positioning. Thus, when the occlusion device is pushed distally out of the delivery catheter into the aneurysm, the guide region guides the distal portion away from the aneurysm through the neck such that the proximal portion passes over the neck and generally remains within the aneurysm.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Patent Application Serial No. 15 / 228,278, filed August 4, 2016, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present technology generally relates to devices, systems and methods for treating vascular defects. Background technique [0004] An aneurysm is a congestive dilation of a blood vessel, usually caused by disease or weakening of the vessel wall. The walls of the aneurysm can gradually thin, which increases the risk of rupture leading to hemorrhagic stroke or even sudden death. In the United States, about 30,000 to 40,000 aneurysms rupture each year, accounting for about 5% of all strokes. The prognosis after aneurysm rupture is poor; the 30-day mortality rate is approximately 45%, and only 40-50% of survivors achieve a positive functional outcome. Conventional methods of preventing aneurysm rupture usually in...
