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.
Claims9
A medical probe, comprising:
- a flexible insertion tube, having a distal end for insertion into a body cavity of a patient, the insertion tube comprising a magnetic field generator within the distal end of the insertion tube for generating a magnetic field;
- 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, the distal tip comprising a position sensor within the distal tip, wherein the position sensor is configured to generate a signal in response to the magnetic field, and wherein the signal is indicative of a position of the distal tip;
- and
- a coupling member, which couples the distal tip to the distal end of the insertion tube and comprises a tubular piece of an elastic material having a helical cut therethrough along a portion of a length of the piece.
