Instructions for use: Ikus - Berlin Heart

De-air the pump
Implantation: Preparation in the operating room
Instructions
1. Have the trocar (de-airing needle with obturator) at hand. Remove the protective silicone
cap.
2. Insert the trocar as shown above through the middle of the de-airing nipple of the pump
up to the stop. To do so, turn the trocar slightly (max. 10°) back and forth.
3. Remove the obturator.
4. Pull back the de-airing needle approx. 2 mm. Important: The tip of the cannula is still
visible in the blood chamber.
5. Fix the de-airing needle to the de-airing nipple using the ligature.
6. Pump with PU valves: Pull the adapter tube off the pump.
7. Pump with tilting-disk valves: Pull the tube of the pressure gauge set off the pump, pull
the pump seal off the outflow side and lay both of them out.
Rinse and fill the blood pump
Instructions
1. Fill the pump once or twice with sterile saline solution. To do so, pour sterile saline
solution through the inflow connector into the pump. Empty the pump.
2. Insert the free end of the de-airing tube onto the de-airing needle up to the stop.
3. Fill the syringe with sterile saline solution.
4. Connect the syringe to the stop cock of the de-airing tube.
5. Slowly fill the pump with sterile saline solution. Move possible air bubbles to the outflow
stub by swinging the pump.
6. Lock the stop cock of the de-airing tube.
7. Tap lightly with the de-airing hammer against the pump housing to dislodge air bubbles.
De-air the pump fully via the de-airing needle and the outflow stub.
8. Close both titanium connectors with the pump seal.
9. Lay out the prepared pump. The connectors point upward.
Recommendation
• Before starting the operation, mark the later incision wound sites of the cannulas.
The goal is a stable and tension-free spatial end position of the cannulas. In the case
of biventricular assistance/ support, ensure that two of the four cannulas cross over.
If possible, this should occur outside of the thorax.
