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： A temporary aortic occlusion device is disclosed, having an expandable locator portion and an expandable occlusion portion. The expandable locator portion assists a user in determining whether the distal end of the device has been advanced within a patient's aorta, and the occlusion portion is expanded to occlude the patient's aorta, preferably below the renal arteries.
