Abstract
A device for capturing debris from blood flow in a blood vessel, the device including an expandable frame shaped and sized to expand against walls of a blood vessel, a debris obstacle attached to the frame, and a control wire attached to the debris obstacle, configured to control opening of the debris obstacle, wherein the control wire extends from the debris obstacle upstream in relation to a direction of blood flow in the blood vessel. A method for preventing debris from reaching a lung, the method including inserting a device for capturing debris to a location in a vein, controlling debris traps in the device to open and collect debris from the vein, performing the medical procedure, and extracting the device for capturing debris from the body. Related apparatus and methods are also described.
