Abstract
Apparatus for treatment of circulatory arrest includes a manually operated ultrasound probe (1) for localizing and puncture of a superficial artery (2) with a cannula (8) by which, subsequently, a catheter (10) is inserted towards the heart. The catheter (10) contains an elastically inflatable balloon (14,15) by which the distal aorta can be occluded, thereby making possible the injection of concentrated fluid through openings in the distal part of the catheter (10) from an ampoule (19) containing agents for activation of the cardiac muscle, for blood vessel dilation, for dissolving of blood clots or for protection against hypoxic injuries. The apparatus is controlled by a program stored in a memory unit (41) of a central processing unit (40). One or more pressure sensors (23), driving units (22), and pressure generators (21) are used to control the sequential processes.
