Abstract
A system includes a catheter and a processor. The catheter includes an expandable distal-end assembly (EDEA) having: (i) a transmitter, which is coupled to the EDEA and is configured to transmit a first signal, and (ii) one or more receivers, which are coupled to an elastic component of the EDEA, and are configured to produce one or more respective second signals in response to receiving the first signal. The processor is configured to estimate, based on the one or more respective second signals, a force applied to the elastic component.
Claims20
A system, comprising:
- a catheter, comprising an expandable distal-end assembly (EDEA) having:
- (i) a transmitter, which is coupled to the EDEA and is configured to transmit a first signal, and (ii) one or more receivers, which are coupled to an elastic component of the EDEA, and are configured to produce one or more respective second signals in response to receiving the first signal;
- and
- a processor, which is configured to estimate, based on the one or more respective second signals, a force applied to the elastic component.
A method, comprising:
- inserting into an organ of a patient a catheter comprising an expandable distal-end assembly (EDEA) having:
- (i) a transmitter, which is coupled to the EDEA for transmitting a first signal, and (ii) one or more receivers, which are coupled to an elastic component of the EDEA for producing one or more respective second signals in response to receiving the first signal;
- applying the first signal to the transmitter and receiving the one or more respective second signals;
- and
- estimating, based on the one or more respective second signals, a force applied to the elastic component.
A method for producing a catheter, the method comprising:
- coupling, to an expandable distal-end assembly (EDEA) of a catheter, a transmitter for transmitting a first signal;
- coupling, to an elastic component of the EDEA, one or more receivers for producing one or more respective second signals in response to receiving the first signal;
- and
- electrically coupling at least the one or more receivers to a processor for receiving the one or more respective second signals and for estimating, based on the one or more respective second signals, a force applied to the elastic component.
