<P>PROBLEM TO BE SOLVED: To provide a catheter equipped with a pressure sensor capable of correctly determining an intraventricular pressure of a patient. <P>SOLUTION: The intraventricular pressure sensor has a catheter having a first lumen to receive a fluid flowing the inside and a second fluid impermeable lumen enclosing a fluid. The second lumen extends between the pressure sensor element to fit an exposed outer pressure source and a pressure sensor capable of determining the pressure of the outer pressure source corresponding to the displacement of the pressure sensor. The intraventricular pressure sensor is particularly advantageous in direct determination of the intraventricular pressure of the patient. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
