    摘要: A vascular occlusion device includes a braided filament mesh structure defining a longitudinal axis. The mesh structure has a relaxed configuration in which it has an axial array of radially-extending occlusion regions, each of which has a proximal side and a distal side meeting at a peripheral edge, the sides of each occlusion region forming a first angle relative to the longitudinal axis. Each occlusion region is axially separated from the adjacent occlusion region by a reduced-diameter connecting region. The mesh structure is radially compressible to a compressed state in which it is deployed intravascularly to a target site through a catheter. Upon deployment, the device radially expands to a constrained configuration in which the peripheral edges of the occlusion regions engage the vascular wall, and the sides of the occlusion regions form a second angle relative to the longitudinal axis that is smaller than the first angle.

    摘要: In a system and method for deployment of an implant device, the implant device includes a first loop at its proximal end, and a deployment tool has a second loop attached at its distal end. A release wire slidably disposed within the deployment tool has a distal end extending through the first and second loops to releasably couple the implant device to the deployment tool, and a proximal portion extending from a proximal end of the deployment tool, which is held in a retraction device. The retraction device is operable to hold the proximal end of the deployment tool and to pull the release wire proximally through the deployment tool until the distal end of the release wire is withdrawn from the first and second loops to decouple the implant device from the deployment tool.

    摘要: A system and method for managing an occlusion, such as a blood clot, within a lumen or passageway of a patient. More particularly, a system and method for rapidly restoring blood flow through an occlusion including a self-expanding, tubular member through which blood may flow when in an expanded state. The tubular member has a structure configured to engage the occlusive material, thereby allowing for extraction of at least a portion of the occlusive material. The system may further employ a material extraction member that is deployed distally of the tubular member.

    摘要: Embolic protection devices for placement in an arterial system of a human and methods of using such devices. In one embodiment, the device includes a filter having a first filter section configured to be deployed along the ascending aorta and aortic arch, a tapered second filter section extending proximally from the first filter section, and a proximal portion extending proximally from the second filter section. The second filter section is configured to be deployed along the descending aorta, and the proximal portion extends to a position below a renal artery. The embolic protection device can be configured to continuously filter the arterial system blood between a distal end of the first filter section to a position within the arterial system downstream of the renal artery.

    摘要: Systems and methods for forming a tubular braid are disclosed herein. A braiding system configured in accordance with embodiments of the present technology can include, for example, an upper drive unit, a lower drive unit, a mandrel coaxial with the upper and lower drive units, and a plurality of tubes extending between the upper drive unit and the lower drive unit. Each tube can be configured to receive individual filaments for forming the tubular braid, and the upper drive unit and the lower drive unit can act against the tubes in synchronization to cross the filaments over and under one another to form the tubular braid on the mandrel.
