Placenta as an ex vivo vascular model for testing of thrombolectomy and pipeline devices

the effects of endothelial damage during thromblectomy are uncertain. The human placenta vascular model is ideal to test various stentrievers and suction devices and to show the behaviour and potential intimal damage that could have been happened during stroke treatment.

ICG imaging

The placental vessels are visualized by infrared 800nm filter.

Marking of the placental vessels

The placental vessels are marked. One half of the placenta is used for testing and the other half for control.

Thrombolectomy simulation

Clot is inserted into the vessel and stentriever is deployed across the clot.

Clot retrieved

Clot was removed by a tested clot retriever.

Testing of flow diverter

A pipeline flow diverter was inserted into embical vessels for testing the intraluminal behavior.

Fast

The tested segment was harvested for histolotical studies.

Compression

Packing of the pipeline stent outside the embilical vessel.

Organic

Standard stentriever of removing the clot from embilical vessel.

Stretching

Stretching of the pipeline stent
