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.
Claims11
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 operatively connected to the receiver and operative to haptically stimulate the operator responsively to the signals such that the degree of the haptic stimulation experienced by the operator correlates to the amount of the contact force, wherein the haptic stimulation is a vibration with a periodicity, and the period correlates with the contact force.
