Training set-up for trans-femoral smart canula® application with Seldinger technique

- puncture of the femoral vein
- guide wire insertion
- check position with TEE
- tip positioning in the superior vena cava
- check position with TEE
- smart canula® collapsed (stretched) with mandrel
- smart canula® insertion over the wire
- guide wire removal
- mandrel removal
- smart canula® expands spontaneously
- check position with TEE



Clinical smart canula® application with Seldinger technique for remote cannulation

- puncture of the femoral vein
- guide wire insertion
- tip positioning in the superior vena cava
- stepwise dilatation of the access orifice
- smart canula® collapsed (stretched) with mandrel
- smart canula® insertion over the wire
- guide wire removal
- mandrel removal
- smart canula® expands spontaneously



Clinical smart canula® application for Ross procedure (pulmonary autograft in aortic position):

at this stage the leaflets of the neo-aortic valve are tested. Single central cannulation with cardioplegic arrest was selected for the left side and assisted beating heart for the right side. Note, the relatively deep smart canula® position in order to avoid air locks.



Smartcanula principle (schematic view):

"Collapsed insertion and expansion in situ" with Seldinger technique
