Abstract: A neural network apparatus receives, as input from a user device, digital imaging information and the clinical information for an aneurysm patient and generates, using a neural network trained for aneurysm outcome prediction, the digital imaging information, and the clinical information, an outcome prediction for at least one intrasaccular implant device for implant in an aneurysm sac identified in the digital imaging information and having a highest predicted likelihood of complete occlusion of the aneurysm sac from a set of potential treatment devices. The apparatus is further configured to output, for display on a device, an identification of the at least one intrasaccular implant device and the outcome prediction for each of the at least one intrasaccular implant device.

Abstract: Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a permeable implant having a radially constrained state configured for delivery within a catheter lumen, an expanded state, and a plurality of elongate filaments that are woven together. The permeable implant may include a stiffer proximal portion that is configured to sit at the neck of an aneurysm. The stiffer proximal portion may include coils, stiffening elements, or reinforcement elements disposed about or associated with the filaments or woven together with the filaments.

Abstract: Devices and methods for treatment of a patient's vasculature may include a resilient self-expanding permeable implant having a plurality of elongate filaments secured in a hub at a proximal end of the permeable implant. Each of the plurality of elongate filaments may have a diameter between about 0.0005 and about 0.005 inches. The implant includes at least some filaments consisting of nitinol and at least some composite filaments that are drawn filled tube wires comprising an external nitinol tube and a radiopaque material concentrically disposed within the external tube. The implant has at least about 40% composite filaments relative to a total number of filaments, and wherein a total number of filaments is about 10 to about 300.

Abstract: Methods and devices for treating a cerebral aneurysm are described. The device may include proximal and distal self-expanding resilient permeable shells each including a plurality of elongate resilient filaments having a braided structure. The distal permeable shell may include a first plurality of filaments gathered at least at the proximal end thereof. The proximal permeable shell may include a second plurality of filaments are gathered at least at the proximal end thereof. The expanded state of the distal permeable shell may have a convex shape at the distal end of the distal permeable shell and the expanded state of the proximal permeable shell may have a generally convex shape at the proximal end of the proximal permeable shell. The expanded states of the distal and proximal permeable shells may also define a toroidal cavity through which an elongate support member extends.

Abstract: Devices and methods for treatment of a patient's vasculature may include a resilient self-expanding permeable implant having a radially constrained elongated state configured for delivery within a catheter lumen and an expanded state with a longitudinally shortened configuration, and a plurality of elongate filaments which are woven together. Each of the plurality of elongate filaments may have a diameter between about 0.0005 and about 0.005 inches. The implant includes at least some filaments consisting of nitinol and at least some composite filaments that are drawn filled tube wires comprising an external nitinol tube and a highly radiopaque material concentrically disposed within the external tube. The implant has at least about 40% composite filaments relative to a total number of filaments, and wherein a total number of filaments is about 10 to about 300.
