Abstract: Apparatus with a pneumatic or hydraulic or mechanical therapeutic catheter. The therapy energy required to treat internal vessels of the patient is transferred by the same fluid or the same elements from the proximal end section to the distal end section of the catheter that transfer information from the distal end section to the proximal end section of the catheter. The information provides understanding of the state of the vessel and how the therapy fluid of the therapy element of the catheter acts on the vessel.

Abstract: A method and apparatus for removing air from blood which contains air. The air-containing blood is conducted through a cyclone device as a rotating cyclone stream, so that centrifugal forces for the separation of the air from the blood are produced in the rotating cyclone stream.

Abstract: The invention concerns a method and apparatus for removing gas from blood, comprising drawing blood through a non-rotating centrifuge chamber, the chamber having an inlet above and an outlet below with the chamber narrowing like a funnel between the inlet and the outlet. The inlet is oriented for directing the flow tangentially into the blood inlet and around the centrifuge chamber. The outlet is connected to a suction source for drawing off blood without reversal of the direction of rotation of the stream of blood in the chamber. The blood is further directed in the direction of flow of blood obliquely downward into the centrifuge chamber with an upwardly open angle to the axis rotation that is less than 90.degree.. An additional chamber communicates with the centrifuge chamber above the blood inlet and defines a gas base that is larger in cross-section than the gas outlet for providing a gas base for separation of the gas and blood.
