Abstract
An ablation apparatus includes a flexible probe adapted for insertion into a heart of a living subject. The probe has a distally disposed ablation electrode to be brought into contact with a target tissue in the heart, and has facilities for measuring contact force with the target tissue. The apparatus includes a transmitter, operative to transmit an indication of the contact force to a wearable device having an actuator operative to haptically stimulate the operator responsively to the indication.
Claims20
An ablation apparatus, comprising:
- a flexible probe adapted for insertion into a heart of a living subject and having a distally disposed ablation electrode to be brought into contact with a target tissue in the heart, wherein the probe is operative for making a measurement of a contact force between the probe and the target tissue;
- a power source, controlled by an operator, and operative to apply a dosage of energy via the ablation electrode to the target tissue to ablate the target tissue;
- a transmitter, operative to transmit an indication of the measurement of the contact force;
- and
- a wearable device having a receiver for receiving signals from the transmitter and an actuator operative to haptically stimulate the operator responsively to the signals.
A method of ablation, comprising the steps of:
- inserting a probe into a body of a living subject, the probe having an ablation electrode;
- urging the ablation electrode into a contacting relationship with a target tissue;
- making a measurement of a contact force between the ablation electrode and the target tissue;
- haptically communicating the measurement to an operator;
- and
- responsively to the communicated measurement, adjusting the probe to achieve a desired value of the contact force while ablating the target tissue using the ablation electrode.
A method of ablation, comprising the steps of:
- inserting a probe into a body of a living subject, the probe having an ablation electrode and a sensing electrode;
- urging the ablation electrode into a contacting relationship with a target tissue;
- thereafter making a measurement of at least one electroanatomic parameter at the target tissue with the sensing electrode;
- haptically communicating the measurement to an operator;
- and
- responsively to the communicated measurement ablating the target tissue using the ablation electrode.
