摘要： Blood vessel occlusion devices, systems and methods, in particular embodiments of devices for aortic occlusion. The device includes one or more locator portions and an occluder portion. The device is delivered via transcatheter delivery. The locator portion may be radially expanded using a handle and actuator at the proximal end of the delivery catheter. Tactile feedback from the locator portion is used to determine proper location of the occluder portion, for example within the abdominal aorta. The occluder is then radially expanded to occlude the vessel.

摘要： Devices, systems, and methods used to seal a treatment area to prevent embolic agents from migrating are described. The concept has particular benefit in allowing liquid embolic to be used with a variety of intravascular therapeutic applications, including for occluding aneurysms and arteriovenous malformations in the neurovasculature.
