  • Publication number: 20200269016
    Abstract: A medical device delivery system can be used to advance a medical device to a target area within a patient's vasculature. The system can comprise a catheter, a support sheath, and a core member coupled to a medical device. The core member can be used to longitudinally advanced or retracting medical device within a lumen of the support sheath. The support sheath can be advanced within the catheter until a distal end of the support sheath contacts or abuts a reduced diameter section of the catheter lumen. Thereafter, the core member can be advanced into the catheter lumen toward the target area.

  • Publication number: 20200197017
    Abstract: 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.

  • Patent number: 9572652
    Abstract: Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.
