Implantable Microsystems for augmented liver perfusion

Objective

Development of an implantable blood pump system capable of delivering a flow rate of 1 to 2 litres/minute against a back pressure of up to 50 mm Hg with a maximum diameter of 8 mm and maximum length of 30 mm.
Development of efficient sensing and control functions to the implanted motor/pump system and transmission of power and data by 'leadless' electromagnetic transmission through sub-cutaneous tissue.
Development of a compact, efficient, high energy, rechargeable battery which can be implanted just below the skin.
In vitro liver test models for testing the implantable pump system.

The IMALP project develops a microsystem incorporating a blood pump to improve functions in patients with liver cirrhosis. The proposed system will comprise a fully implantable electric micromotor driven micropump incorporating 'smart' flow, pressure and temperature sensors based on CMOS technology. By employing state-of-the-art ASICs, sensing and electrical processing of sensor signals will be performed on ICs installed within the motor/pump housing, which will be small enough to be implanted into the portal vein of the liver using minimally invasive procedures.
