Abstract
A medical probe includes a flexible insertion tube, having a distal end for insertion into a body cavity of a patient, and a distal tip, which is disposed at the distal end of the insertion tube and is configured to be brought into contact with tissue in the body cavity. A coupling member couples the distal tip to the distal end of the insertion tube and includes a tubular piece of an elastic material having a helical cut therethrough along a portion of a length of the piece.

A medical probe, comprising:
- a flexible insertion tube, having a distal end for insertion into a body cavity of a patient;
- a distal tip, which is disposed at the distal end of the insertion tube and is configured to be brought into contact with tissue in the body cavity;
- a coupling member, which couples the distal tip to the distal end of the insertion tube and comprises a tubular piece of a superelastic alloy having a helical cut therethrough along a portion of a length of the piece;
- a position sensor within the distal tip, the position sensor being configured to generate a signal in response to a magnetic field, and wherein the signal is indicative of a position of the distal tip;
- and
- a magnetic field generator within the distal end of the insertion tube for generating the magnetic field.
