ABSTRACT:
A catheter having a sensor for detecting forces acting on its distal end includes a catheter tube, a chamber defined in the catheter tube. The chamber is filled with silicon gel. The catheter also has a sensor chip and a cap. The sensor has a pressure sensing surface and a backside. The cap transmits the forces acting on the distal end of the catheter tube to the pressure sensing surface of the sensor chip. Further, the catheter has a pressure introducing hole. The pressure introducing hole transmits the forces acting on the periphery of the catheter tube to the backside of the sensor chip. The sensor chip issues signals externally in accordance with the pressures transmitted to its pressure sensing surface and its backside.
