WARNING
If an EXCOR cannula extension set / connecting set is required for
implantation and the length of the tube part needs to be reduced, the
tube part should be cut but only to achieve the following minimum
lengths:
Article Diameter /
Diameter reduction Minimum length
Cannula extension set
A06-006 6 mm 55 mm
A09-009 9 mm 60 mm
A12-012 12 mm 75 mm
Connecting set

Tab. 9-2 Cannula extension set / connecting set: minimum length of tube section
INSTRUCTION
1. Cut the cannulae to the required length. Make the cut perpendicular to the
cannula axis and ensure that the cut is straight.
2. Make sure that the lengths of the 2 cannulae leading to the same pump match.
It must be possible to connect the cannulae to the pump without having to
exert any tension.
9.9 Connecting the blood pumps to the cannulae
WARNING
Ensure that cannulae, blood pump(s) and driving tubes are not subject
to external forces and are free of kinks or sharp bends.
When connecting the blood pump(s), pay attention to the direction of
the arrows on the inflow and outflow stubs. These show the direction of
the blood flow.
