Abstract

The invention relates to a balloon catheter device (1) for use in an aorta of a rabbit or a human being. The device (1) comprises a balloon catheter (2), a syringe (3), an actuator (4), a pressure sensor (5), a balloon retracting unit (6), a first control unit (7) and a second control unit (8). The balloon catheter (2) comprises a flexible tube (10) and a balloon (11) at a distal end (12) of the tube (10) and the syringe (3) comprises a chamber (16) containing a fluid, wherein the chamber (16) is connected to a proximal end of the tube (10). The actuator (4) is adapted for increasing/decreasing a volume of the fluid contained within the balloon (11). The pressure sensor (5) is adapted for sensing an inflation pressure of the balloon (11) and the balloon retracting unit (6) is adapted for retracting the balloon (11) out of the aorta. The first control unit (7) is adapted to receive pressure data representing the inflation pressure of the balloon (11) measured by the pressure sensor (5) and to control the actuator (4) depending on the received pressure data, such that the inflation pressure of the balloon (11) is kept stable at a predefined inflation pressure value, and the second control unit (8) is adapted to control the balloon retracting unit (6), such that the balloon (11) is retracted out of the aorta at a constant speed.
