Abstract: A blood pump system including a blood pump, an intravascular flow cannula, and a pressure sensor. The intravascular flow cannula is in flow communication with the blood pump and has a distal end portion distally from the blood pump and a proximal end portion closer to the blood pump. The intravascular flow cannula has at least one blood flow through opening at its distal end portion for blood to enter or exit the flow cannula. The blood flow through opening has a borderline surrounding the through opening. The pressure sensor is configured radially within the flow cannula and borders a proximal portion of the borderline.

Abstract: The present invention relates to an electric handheld file tool for automatically filing down a workpiece. The electric filing tool is designed to save the time and effort associated with manually moving a file tool back and forth. A power source provides power to the motor of the device, and a linear motion is provided by a spindle to a file attachment for filing the workpiece. The spindle converts the rotational motion of the motor to reciprocating back and forth movement of the file attachment. The tool has an activation button for activating the tool, and a speed control button for controlling a speed of the file attachment. The filing tool can be used with a variety of removably attached file attachments, and can also be provided power using conventional 120-volt AC supply or battery power.
