According to some implementations the inner wall surface of the self-expandable member has one or more features protruding therefrom that are adapted to engage the obstruction as the self-expandable member transition from the expanded state toward the unexpanded state. According to other implementations the outer wall surface of the self-expandable member also has one or more features protruding therefrom that are adapted to engage the obstruction as the self-expandable member transition from the unexpanded state toward the expanded state. | 06-09-2016 |
20160157986 | VESSEL OCCLUSION DEVICES, KITS AND METHODS - A blood vessel occlusion device comprising a plurality of legs having a deployed state wherein each of the plurality of legs is angled outwardly toward a vessel wall and a delivery state wherein the plurality of legs are sized and shaped for pushing into a target blood vessel and substantially in parallel to a common longitudinal axis. Each leg has an anchoring tooth at a distal end thereof and a gripping point formed therealong. Each leg switches from deployed state to delivery state by a retention element and maintained in delivery state when said retention element is supported by the gripping point. | 06-09-2016 |

20220133288 | MICROGRAFT FOR THE TREATMENT OF INTRACRANIAL ANEURYSMS AND METHOD FOR USE - A device for occluding a vasculature of a patient including a micrograft having an absorbent polymeric structure with a lumen of transporting blood. The micrograft has a series of peaks and valleys formed by crimping. The occluding device is sufficiently small and flexible to be tracked on a guidewire and/or pushed through a microcatheter to a site within the vasculature of the patient. Delivery systems for delivering the micrografts are also disclosed. | 05-05-2022 |
