A percutaneous system 1 comprising an intracorporeal connector 2 for fluid communication between two compartments through an anatomical wall. Preferably there is an expandable anchor which extends parallel to the wall and an expandable shield which does not substantially contact the wall in a conical shape. A flow regulating device, preferably a pump, may be used to pump fluid (blood) through the hole in the wall. The pump may have a screw type blade. The connector may be manufactured from a shape memory material and include a gate (valve) in the neck portion. The system may contact the fluid with one or more drug compounds, or insert oxygen into it. It may be inserted using a percutaneous insertion device comprising a needle, guide wire, puncture head with preferably a solid tip and a dilator. Preferably it is inserted into the heart as part of a ventricular assist device (VAD). A method of inserting the device is also claimed.
