EXCOR cannulas
Description: Blood pump, cannulas, accessories
EXCOR blood pumps consist of a transparent polyurethane (PU) housing divided by a
flexible triple-layer membrane into a blood chamber and an air chamber.
From the blood chamber, an inflow or outflow stub lead to an inflow or outflow cannula.
The stubs themselves consist of PU. At their ends, there are titanium connectors to
which the cannulas are attached. Mechanical valves in the stubs guarantee a targeted
blood flow. EXCOR blood pumps are available with tilting-disk valves (50 - 80 ml stroke
volume) or trileaflet valves made from polyurethane (10 - 80 ml stroke volume).
The blood contact surface of the pump is coated with Carmeda ® BioActive Surface
(CBASTM ). The transparent housing of the blood pump permits easy visual inspection,
so that the filling and emptying and the status of the blood chamber can easily be
monitored.
By means of the de-airing nipple in the blood chamber, the pump is de-aired during
commissioning with the aid of the de-airing set.
The air chamber of the pump is equipped with a driving tube connector. This connects
to the air-conducting driving tube that links the pump to the Driving Unit Ikus. With
suction and driving pressures, the Ikus actuates the triple-layer membrane of the blood
pump. To minimize friction, there is graphite powder between the individual
membranes.
3.2 EXCOR cannulas
For EXCOR, three cannula types in three different sizes are offered:
• Atrial cannulas (inflow cannulas)
• Apex cannulas (inflow cannulas)
• Arterial cannulas (outflow cannulas)
The cannulas consist of tissue-friendly silicon. Suture rings made from polyester velour
permit fast and safe anastomosis of the cannulas. The midsection of every cannula is
sheathed with polyester velour to ensure good inward movement of the cannula.
Some arterial cannulas possess a flexible metal reinforcement that permits the
adjustment of the cannulas to the anatomical conditions.
Some atrial cannulas are delivered with a mandrin.
