<P>PROBLEM TO BE SOLVED: To provide a new design of an invasive probe such as a catheter or the like and a system and method using the probe. <P>SOLUTION: A medical probe includes a flexible insertion tube, having a distal end for insertion into a patient's body cavity, and a distal tip, which is disposed at the distal end of the insertion tube and configured to be brought into contact with tissue in the body cavity. A resilient member couples the distal tip to the distal end of the insertion tube and is configured to deform in response to pressure exerted on the distal tip when the distal tip engages the tissue. A position sensor within the probe senses a position of the distal tip relative to the distal end of the insertion tube, which changes in response to deformation of the resilient member. <P>COPYRIGHT: (C)2009,JPO&INPIT |
