摘要: Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A treatment system for such treatment can include an electrolytically corrodible conduit having a proximal portion, a distal portion, and a detachment zone between the proximal portion and the distal portion. An occlusive member having a proximal hub is coupled to the conduit distal portion. The conduit has a lumen configured to pass an embolic element therethrough. An inner electrode assembly can be slidably disposed within the conduit lumen to facilitate electrolytic detachment of the occlusive member at the detachment zone.

摘要: Systems and methods for treating an aneurysm in accordance with embodiments of the present technology include intravascularly delivering an occlusive member to an aneurysm cavity and deforming a shape of the occlusive member via introduction of an embolic element to a space between the occlusive member and an inner surface of the aneurysm wall.

摘要: Systems, methods, and devices for treating vascular defects are disclosed herein. In some embodiments, a method of treating an aneurysm includes positioning a distal portion of an elongated member near or within an aneurysm. The method can include introducing an embolic composition into a lumen of the elongated member using an injector device coupled to a proximal portion of the elongated member. The injector device can pressurize the embolic composition to a pressure of at least 10,000 psi. The method can also include delivering the embolic composition into the aneurysm via the elongated member.

摘要: Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A delivery system for such treatment can include an occlusive member configured to be positioned within an aneurysm sac and having a proximal hub. An elongate tubular member has an engagement member removably coupled to the proximal hub, for example via threaded engagement or an interference fit via one or more engagement members. A conduit extending within or adjacent to the elongated member is configured to receive an embolic element therethrough for delivery to the aneurysm sac.

摘要: Systems and methods for treating an aneurysm in accordance with embodiments of the present technology include intravascularly delivering an occlusive member to an aneurysm cavity via an elongated shaft and transforming a shape of the occlusive member within the cavity. The method may include introduction of an embolic element to a space between the occlusive member and an inner surface of the aneurysm wall. In some embodiments, the elongated shaft is detachably coupled to a distal portion of the occlusive member.

摘要: Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.
