Abstract
A catheter includes an inflatable balloon for insertion into an organ of a patient, one or more electrodes and a coil. The one or more electrodes are disposed on a surface of the inflatable balloon and are configured to be placed in contact with tissue of the organ, and to perform at least one of: (i) sensing one or more electrical signals from the tissue, and (ii) applying one or more ablation pulses to the tissue. The coil is disposed on the surface of the inflatable balloon, and is configured to output a signal indicative of at least one of: (i) a temperature of the tissue, and (ii) a magnetic field indicative of a position of the catheter in the organ.
Claims20
A catheter, comprising:
- an inflatable balloon for insertion into an organ of a patient;
- one or more electrodes, disposed on a surface of the inflatable balloon and configured to be placed in contact with tissue of the organ, and to perform at least one of:
- (i) sensing one or more electrical signals from the tissue, and (ii) applying one or more ablation pulses to the tissue;
- and
- a coil, which is disposed on the surface of the inflatable balloon, and is configured to output a signal indicative of at least one of:
- (i) a temperature of the tissue, and (ii) a magnetic field indicative of a position of the catheter in the organ.
A catheter, comprising:
- an inflatable balloon for insertion into an organ of a patient;
- one or more electrodes, disposed on a surface of the inflatable balloon and configured to be placed in contact with tissue of the organ, and to perform at least one of:
- (i) sensing one or more electrical signals from the tissue, and (ii) applying one or more ablation pulses to the tissue;
- and
- one or more thermocouples, which are coupled to the surface of the inflatable balloon for sensing the temperature of the tissue.
A method for producing a catheter, the method comprising:
- receiving a flexible substrate comprising electrical interconnections formed on a first layer;
- forming, on a second layer of the flexible substrate, a coil, and connecting ends of the coil to the electrical interconnections;
- coupling one or more electrical devices to the flexible substrate and connecting the electrical devices to the electrical interconnections;
- and
- wrapping the flexible substrate around an inflatable balloon, and coupling the inflatable balloon to a distal end of a shaft of the catheter.
A catheter, comprising:
- an expandable balloon defining a longitudinal axis extending through the balloon, the balloon having a compound curved surface of revolution about the longitudinal axis;
- one or more electrodes, disposed on the compound curved surface of the expandable balloon and configured to be placed in contact with tissue of the organ, and to perform at least one of:
- (i) sensing one or more electrical signals from the tissue, and (ii) applying one or more ablation pulses to the tissue;
- and
- at least one coil defining a coil axis extending at an angle to the longitudinal axis of the balloon, the at least one coil being disposed on the compound curved surface of the expandable balloon.
