A catheter with a pressure sensor is provided to prevent punching on a heat wall and comprehensive damage to a tissue by maintaining an optimum contact between a tip and the tissue. A catheter comprises a flexibility insert tube(54), and the flexibility insert tube has the distal end to be inserted into the coelom of patient. The distal tip(52) is connected to the distal end of the insert tube by an elastic member(58). The elastic member unites the distal tip with the distal end of the insert tube. When the distal tip unites organization, the relative motion of the limited range between the distal tip and the insert tube is allowed in response to the pressure displayed in the distal tip. The magnetism position sensor(62) includes more than one compact coils while being within a probe for sensing the location of the distal tip. |
