Abstract
Abstract A miniaturized transducer for in vivo measurements of physiological pressure has a transducer unit (2, 3) and an inner tube (1) with a wall opening (6). A diaphragm (5) covers the wall opening. Distinguishing for the invention is that the diaphragm is protected by an outer tube (8) arranged outside the inner tube, and having a wall opening (9) situated radially opposite the wall opening of the inner tube. An end closure closes off the distal end of the tube and a seal (16) seals the outer tube against the inner tube. The lumen (4) of the inner tube is in communication with the atmospheric pressure.
