    摘要： Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.

    摘要： Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to a medical device. The device can include an elongate core member having a distal portion configured to be intravascularly positioned at a treatment site within a blood vessel lumen, and an interventional element connected to the distal portion of the elongate core member. The interventional element includes a body that is expandable from a first configuration to a second configuration and an electrically conductive radiopaque marker coupled to the body. An electrically conductive lead has a distal portion electrically coupled to the radiopaque marker and a proximal portion configured to be electrically coupled to a current source.
