A device capable of sensing pressure allows the sensor and amplifying electronics to be packaged in a very small size and implanted within the body. The sensor consists of a small catheter, the tip of which is placed at the point at which pressure is to be measured, attached to a solid-state pressure sensor. The catheter is filled with a fluid and is connected to an implantable infusion pump which dispenses through the lumen of the catheter, heparin or other drug which inhibits thrombogenisis.
