Abstract
A sensor mounted on the distal end of an intra-corporeal catheter detects pressure applied thereto. The sensor includes a chip that is deformable in accordance with pressure applied thereto, strain gauges mounted on the chip, a sensing plate, a projection, a cap and a tube. A cover covers the chip, the sensing plate, the projection and the cap and gives a smooth tapered shape to the catheter's distal end. The projection and the cap transmit pressure applied to the catheter's distal end to the sensing plate and tilt the sensing plate in accordance with the pressure. The strain gauges issue detection signals according to the degree and the direction of the tilting. The pressure applied to the catheter's distal end is detected based on the issued signals.
