Abstract
An invasive medical probe includes an insertion tube, having a distal end for insertion in a body cavity of a patient. A metallic material is disposed over the distal tip of the insertion tube and extends from the tip so as to cover a portion of the distal end. An acoustic sensor is contained entirely within the portion of the distal end of the insertion tube that is covered by the metallic material.
Claims15
An invasive medical probe, comprising:
- an insertion tube, having a distal end for insertion in a body cavity of a patient, the distal end terminating in a distal tip;
- a metallic material disposed over the distal tip of the insertion tube and extending from the tip so as to cover a portion of the distal end;
- and
- an acoustic sensor, contained entirely within the portion of the distal end of the insertion tube that is covered by the metallic material.

Apparatus for medical treatment, comprising:
- an invasive medical probe, which comprises:
- an insertion tube, having a proximal end and a distal end for insertion in a body cavity of a patient, the distal end terminating in a distal tip;
- a metallic material disposed over the distal tip of the insertion tube and extending from the tip so as to cover a portion of the distal end;
- an acoustic sensor, contained entirely within the portion of the distal end of the insertion tube that is covered by the metallic material;
- and
- cabling, running from the proximal end to the distal end within the insertion tube and coupled to the metallic material and to the acoustic sensor at the distal end;
- a radio frequency (RF) generator, which is coupled to the cabling to as to supply RF energy to the metallic material for ablation of tissue with which the metallic material is in contact within the body cavity;
- and
- an acoustic processor, which is coupled to the cabling so as to receive and process an audio signal generated by the acoustic sensor in order to provide an indication of the ablation.

A method for medical treatment, comprising:
- inserting a probe into a body cavity of a patient, the probe comprising an insertion tube having a proximal end and a distal end terminating in a distal tip, with a metallic material disposed over the distal tip of the insertion tube and extending from the tip so as to cover a portion of the distal end, and an acoustic sensor contained entirely within the portion of the distal end of the insertion tube that is covered by the metallic material;
- bringing the distal tip of the probe into contact with tissue within the body cavity;
- applying radio frequency (RF) energy to the metallic material so as to ablate the tissue with which the distal tip is in contact;
- and
- receiving and processing an audio signal generated by the acoustic sensor in order to provide an indication of ablation of the tissue.
