Abstract
A catheter includes a longitudinally extending catheter tube to be inserted into a body. A plurality of sensing portions are arranged in the catheter tube for detecting at least two types of pressures acting on the catheter when inserted into the body. Each sensing portion is arranged along the longitudinal direction of the catheter tube. A silicone gel transmits the two types of pressures acting in the body to each sensing portion. The two types of pressures act on each sensing portion in a radial direction of the catheter tube by way of the silicone gel.
