[Heart assist systems with integrated microsensors (HIM 2)]

The use of intracardiac pump systems is leading to more physiological support for coronary surgery patients. But the currently available micro blood pump with an integrated micro pressure sensor and an outer diameter of 6.5 mm is not suitable for a transfemoral placement of the device. Therefore a significantly smaller pump with an outer diameter of 4 mm (12F) is been developed and tested. To transfer the sensor technology in this, for the first time the MID (moulded interconnected device) technology is applied in a medical device. In a first step MID is used to integrate a smaller pressure sensor on the existing blood pump. The result should help to find a new packaging and connecting solution for integration of the miniaturized sensor on the 4 mm pump.
