SELF-DEPLOYING AXIAL-FLOW PUMP INTRODUCED INTRAVASCULARLY FOR TEMPORARY CARDIAC SUPPORT

摘要

The axial-flow pump for introduction through the vascular system of a patient has a flexible compressible tube (1) forming the pump housing. A radially compressible rotor (7) is located within the tube (1). The drive shaft (6) of the rotor (7) extends through a catheter (4). The catheter (4) can be pulled into a cover hose (5) together with the tube (1) and the rotor (7).
